N.B. Editor's note: Steve Bowbrick will be working for 大象传媒 Future Media & Technology as a "blogger-in-residence" for the next six months looking at, and talking about, ideas for a and the 大象传媒 becoming more open. Make him welcome!

, Nick Reynolds and [no relation] at the Social Media Champions session at FM&T's Open Week

It's a truism that institutions that are important in one era find it difficult to maintain their relevance in the next. Everyone knows that the 大象传媒 in its second great era - the one starting about now - is going to be markedly different from the one that dominated the British broadcast ecology for the last 80 years. So far, so obvious.

The question, of course, is how will it differ? What will a national broadcaster funded by its viewers look like once the network era is properly underway? Can it survive in its current form at all?

Big questions. Happily. not ones that I plan to answer. Which brings me to my new job here.

I've been blogger-in-residence at 大象传媒 FM&T for a few days (I don't have my staff pass yet but I'm on the Beeb part of the microblogging system). I realise I've made it to 45 years old without ever working at the 大象传媒, and it's genuinely exciting:

I find a big, breezy rather optimistic place full of brainy people (lots of them quite young) doing a huge variety of interesting things, many of which are aimed in one way or another at answering those big questions.

And the word that's on more or less everybody's lips is "openness".

? How open can we be?

? Should we share this insight with outsiders?

? Should we be opening our banks of content and code to licence fee payers, entrepreneurs and organisations?

And for the 大象传媒, these questions are given an extra urgency by the context: by the chaotic , by Ofcom's apparently unending , by the of the Kangaroo JV and even by Channel 4's bid for the social media high ground with .

So, fear of notwithstanding, over the next few months, I plan to roam the 大象传媒's corridors - with my trusty guide Nick Reynolds - meeting everyone who has an opinion or an interesting project or a problem to solve with some relevance to the 大象传媒's increasing openness and readiness to share.

I've been writing about this sort of thing for a long time (I've got cuttings going back to 1996) and not long ago, I helped to organise an event at Broadcasting House called , which some of you will have attended.

You should bookmark or subscribe to [], where I'll be blogging everything.

Meanwhile, if you'd like to know more, or if you'd like to contribute to the project, from inside the 大象传媒 or outside, drop me a line or visit (and forgive me while I get the site finished!). And if you work for the Beeb and you see me in a corridor, stop me and say something entertaining.

More on Olinda here and here.

Audio & Music tech chief James Cridland has been in Stockholm, Oslo and Copenhagen, agreeing with his commercial colleagues on technology and competing on content. The talk he gave with GCap's , Radio For The Facebook Generation, is evidently too involved for a straight embed, so :

Quite a few people asked for a copy of the presentation Nick and I gave. It's 38 meg, and given that I was demonstrating Olinda (our rather nice prototype connected radio) and a rather neat webcam-based piece of software that got a spontaneous round of applause (when it worked!), it's a bit hard to simply forward a PPT file to someone.
[N]ote that the speech doesn't make it clear who's speaking at any one time, so don't take anything in here as official 大象传媒 policy, because it isn't.

And Nick Piggott's complementary post is called .

Back here in the 大象传媒 bloggery, James tells Radio Labs that "iPlayer's teething problems have got substantially better since my last report, but here are a few open issues we're aware of":

• A problem with the satellite receivers we use meant that some programmes had gaps in them recently. We switched to an alternative feed for a bit, which had the effect of putting 大象传媒7 in mono among other things, but the satellite receivers now seem happy. We're sorry about that. Coyopa will fix that.
• Generation of Real Audio files for a small amount of programmes has sometimes failed. We think we've got to the bottom of why this happens, and issues are rather fewer of late. Again, apologies to you - particularly PM fans - if this has spoilt your enjoyment. In the majority of cases, Coyopa will fix that too.
• [Update 2008-09-30 1630: now fixed] Listeners in live Windows Media format within iPlayer might notice, in a minority of cases, that they get kicked off at precisely 15 minutes after they start listening. A fix is on the way shortly; it would appear from preliminary tests that it might be related to Internet Explorer, and that it's potentially related to the recent Windows XP SP3 update, or similar for Vista. It's early days, so we might be wrong here - but we're working on it; latest information I have is that we might have a fix next week. Coyopa will, eventually, fix that as we add AAC-family flash streaming.

Chris Williams talks to 大象传媒 Technical Architect Andy Smith under a very -flavoured headline in The Register, :

This week the Radio Labs blog is going to be leaving the world of technology that we normally write about and will look at another side of the internet. For the past year or so, I have been working with three universities on a study of the online behaviours of listeners and fans of 大象传媒 radio and over the rest of this week, we're going to be publishing guest posts from each of the researchers on their case studies: interactivity on the 大象传媒 Radio messageboards, the off-大象传媒 activity of fans of Terry Wogan, fan cultures around the Archers and how the 大象传媒 serves specialist music fans.

...The Mayan God Of Thunderous Noises

I've been bravely promising a change of audio quality for the 大象传媒's (UK national) radio online streams; and I'm very aware I owe you an update. It's a peculiar thing, writing a blog post that I know will be read by thousands of people who have part-funded the work I do. So, where we have problems, I want you to know about them - as well as our successes.

First, a recap. Project Coyopa, as you're aware from previous postings, is designed to give better audio quality for 大象传媒 radio.

James Cridland is Head of Future Media & Technology for 大象传媒 Audio & Music Interactive.

Thanks for all your questions and comments on my earlier post about audio-on-demand for the iPhone.

Rather than answer them all independently, here are answers to some common questions:

Is audio-on-demand only available on the iPhone?

iPlayer video and audio-on-demand will also be available on the Nokia N96, which Nokia is due to release on October 1st (see Matthew Postgate's previous post). We initially launched this service on the iPhone as it's a very popular device amongst our audio and music audiences, but the 大象传媒's new media teams are working hard to bring audio-on-demand to other mobile devices in the very near future.

Can I stream live 大象传媒 radio on the iPhone?

The iPhone is currently only available on the O2 network in the UK and continuous streaming of audio and video content is not permitted under the terms of O2's flat-rate packages. We're currently working on supporting live streaming when you're connected via wifi.

Can I stream live 大象传媒 radio on other mobile devices?

I would love to make iPlayer available on all mobile devices but as the media support and browser functionalities vary so widely, this may take some time. Where we can be certain that a wifi connection is being used, and that this connection is also used by the device's media player software, then it's already possible to access live streams. For more details see here.

Unfortunately, many mobile devices swap to 3G or GPRS connections without informing their users - which can be very expensive. The 大象传媒 is in discussions with network operators on this issue and hopes that consumer demand will help to drive this change.

Why doesn't 大象传媒 radio podcast all their programmes?

The 大象传媒 negotiates rights with collective bodies and artists' representatives to make streamed material available for up to seven days after broadcast. Where rights allow, we also make 大象传媒 programmes available to download as podcasts. We currently make over 170 titles available as podcasts and this number will continue to grow. The limits we place on this growth are largely down to cost.

Why have on-demand mobile services been prioritised before improving on-line audio quality?

Improving the audio quality of live internet radio streams remains a key priority. This is a much larger piece of work and will take a little longer to complete. There'll be a post later tonight on the Radio Labs blog detailing progress towards this.

Why do some programmes appear as 'currently unavailable'?

The audio-on-demand facility for iPhone, giving people the chance to listen to programmes from "the past seven days", only launched on Monday. So, the complete list of programmes is being built up over this week. All listed 大象传媒 radio shows should be available by Monday September 29th.

Once again, please feel free to leave me your comments about how this service affects how you listen to 大象传媒 radio.

A few months ago, I gave one of the keynotes at our annual 大象传媒 Future Media & Technology conference.

I ended my speech, which ranged from an overview of the evolution of user interaction models on technology to cloud computing and the semantic web, with a picture of the ...

...and the statement:

All this innovation, and yet this is the best we can currently do for content discovery: brute force text search. We have to do better if we want to evolve.

Okay, it was for dramatic effect, but I believed then and believe now that I was absolutely accurate.

Search is one of the darkest backwaters of technological and experience development (particularly on the internet.) Since then, I've been thinking a lot about how we, the 大象传媒, can improve search on our site, and how we can drive innovation around search in general in the industry.

Earlier this month, there were a couple of really interesting launches in the world of search.

Nick Reynolds is editor, 大象传媒 Internet Blog.

Thanks for all your comments to date - I do read them and mentally log them even where I don't respond directly to them in my posts.

I want to deal, though, with some of the comments about the channel content, and also to share with you some of the issues we face in making decisions for the channel.

大象传媒 HD aims to broadcast in HD the best of programming available from the 大象传媒.

Clearly, "best" is quite a subjective term. It could mean the content which works "best" in HD. When we make decisions about where to make HD investments, that is one of our considerations, and part of the reason why the first programming to deliver in HD has been our sport, costume dramas and natural history.

But it's not always possible to predict whether a programme or series will work well in this way - sometimes we can find a strong visual awareness in unexpected places, and sometimes programmes which we expect to look good in HD don't.

But our promise to look to the "best of the 大象传媒" needs also to reflect the programmes that you (and others) in our audience tell us you really like - either because you watch them in large numbers, or because you tell us in other ways that you think they represent really valuable programming.

And the range of programmes there is much broader - we know that it extends to entertainment shows like Strictly Come Dancing and Jonathan Ross, sport, comedy, documentaries, music and also some daytime programmes.

I believe firmly that the 大象传媒 has a responsibility to consider programmes from across the full range of content and channels which we broadcast, and that we should continually experiment with forms of programming which are not available elsewhere in HD.

They may not look as pristine as those programmes for which HD is a more instinctive format, but they add to the range of HD content available to viewers who have invested in HD connections, and they help to ensure that on 大象传媒 HD, as on all other 大象传媒 channels, we are able to offer programmes which suit as wide a range of tastes as possible.

Even though we've been making programmes in HD for some time now, we still have a great deal to learn about the best ways to work with what remains an emerging technology.

A number of you have commented on the picture quality on Jonathan Ross. You're right - the show doesn't look as good at the moment in HD as we would like it to. That's not because - as mwbennett suggests, we're doing it on the cheap, or because light entertainment or studio shows as a whole have a lower quality threshold.

But the conversion of studio TC4 to HD is very recent, and we took a decision that we wanted to bring you the whole series of Jonathan Ross, rather than sorting all technical issues in advance of starting broadcast.

There are still elements affecting picture quality along the broadcast chain that we are working on (and some of these don't just relate to Jonathan Ross). I hope that, as we address them, the picture quality will improve across the channel.

Having said that we want to make sure that the best of the 大象传媒's content is available to you in HD, however that's defined, I have to tell Dazza124 that, unfortunately, Merlin will not be on 大象传媒 HD.

Sometimes, for a whole variety of reasons, the production team decides that it doesn't want to use the format. Those of us on 大象传媒 HD felt that Merlin was a show that we should aim to deliver in high definition, but in the end it was shot in Super 16.

Derek500 asks for the "official" reason for not showing the Strictly Come Dancing results show in HD. I wasn't aware of an "unofficial" reason, but there is no particular issue in discussing why it won't be available on the channel this year.

A lot of work was done to try to ensure that the results show as well as the main show could be made in HD. But the nature of the results show, with lots of small camera filming and a fast turnaround, meant that we were unable to guarantee that the show could be delivered with the requisite proportions of HD content.

I had to take a decision about whether to pursue discussions and invest money which then couldn't be used for other programmes in a show which had a high chance of not actually delivering in HD. Reluctantly, I took the view that we should lose the programme from the HD schedule. It's not a decision I'm particularly pleased about, but in the circumstances it seemed to be the best one to make.

I am discovering that life at 大象传媒 HD is full of this kind of tricky dilemma - to a large extent, it is because the channel and technology are so interwoven into the other things that the 大象传媒 does, and the life of the rest of the channel portfolio.

This is particularly true when it comes to scheduling the channel. We want to bring you the best content available, and we recognise that most of the time you would like to see it in HD at the same time that it is being broadcast in SD.

But sometimes 大象传媒 One and 大象传媒 Two both have something made in HD on at the same time, and sometimes the rights we have to broadcast the content mean that our flexibilty is very restricted.

We have at least two instances coming up. Silent Witness is on at the same time as the first episode of Heroes, which we can only play at the same time as one of the other channels broadcasting it because of the rights we can afford to buy on it.

And we also have a clash between the last episode of the 大象传媒 Two series The Tudors (which I hope you have been enjoying) and the first episode of 大象传媒 One's Little Britain USA - both also acquisitions.

In both cases, we'll aim to broadcast both programmes on the channel - but obviously, only one can go out at the time that it is being shown in SD, and the other slots we have available may be less suited to the content and your lives.

We have heated debates within the team about what the best option is, and I suspect that, whichever programme we choose to prioritise, some of you will feel we've made the right decision and others the wrong one.

I'm interested as ever to know what you think - but also want you to know that even if you don't like the outcomes we get to, the decisions don't get taken lightly.

Danielle Nagler is Head of HDTV, 大象传媒 Vision.

Super Hi-Vision () is a new large-screen television system that is being developed by , the Japanese national broadcaster, in their Science and Technical Research Laboratories ().

SHV has a picture resolution of 4320 lines by 7860 pixels, ie 33 megapixels, ie over 16 times as many pixels as HDTV. SHV also includes 22.2-channel surround sound, with some speakers at ceiling height to provide a 3D audio experience.

大象传媒 Research and Innovation (R&I) is collaborating with NHK STRL to develop practical ways to deliver SVH using a variant of R&I's Dirac video coder. This is a collaboration under the Broadcast Technology Futures (BTF) group; an association of NHK, , , and the 大象传媒 with the aim to carry out research on a wide range of technologies relevant to our industry.

NHK took its experimental SHV theatre to the in Amsterdam this month.

Pictures were projected on a six metre wide screen with the audience only a few metres away; the pictures were so big that they created an -like cinema experience. A short programme was shown featuring wildlife, children and beautiful views of Japan that gave, in NHK's own words, "a sensation of realism". The programme was played back from an uncompressed disk array of several terabytes capacity and a 24 Gb/s transfer rate.

A super high vision camera

The 大象传媒 contribution was a live SHV video link from the balcony of London City Hall using one of only two SHV prototype cameras. The pictures were coded at 640 Mb/s using MPEG-2 and transmitted as IP via the Siemens IT Solutions and Services London Fibre Network to a Cable & Wireless optical cable to Amsterdam.

SIS Live shared the operation of the camera with NHK. They also set up 17 microphones at various heights on a mast and on the building to pick up the ambient sound of London. Siemens provided and ran the technical facilities at each end of the link.

Erik Huggers at one end of the live video link

The Italian broadcaster, RAI, demonstrated satellite broadcasting of SHV at 140 Mbit/s from Turin to IBC.

Is 4000-line TV too detailed for your living room?

Perhaps not, a wall-sized display could show dramas, concerts, to give a feeling of immersion. At other times, the display could be divided up to show different content in "windows", rather like those on a PC display. In the years before SHV would be ready for introduction to the home, this system has the potential to be used for large screen displays for community viewing of sports or special events.

This doesn't mean that HDTV is about to be replaced. It was first demonstrated in Europe 26 years ago, but is only now becoming established in Europe. There are many technical problems to solve before SHV can become practical, which will keep the research labs collaborating for some years to come.

One of the secrets of radio's success has been the ability to listen to it while you're on the move.

Half a century ago, the transistor radio helped to start a revolution in the way people consume media and it's estimated that there are several billion of them being used around the world.

So it's not surprising that lots of people have been asking when they'll be able to listen to the 大象传媒's digital radio services on mp3 players and mobiles.

From today, you'll be able to listen to 大象传媒 radio programmes on demand on an iPhone or iPod Touch for up to seven days after broadcast.

You'll need to be online via a wifi connection and will be able to listen to our radio shows in mp3 format (at 128kbps).

This launch is thanks to the hard work of the 大象传媒's future media teams who have had to adapt audio (and image) formats to suit the iPhone and iPod Touch, change the way audio files are delivered and redesign the service to include the wealth of new content available.

On October 1st, the 大象传媒 iPlayer goes live on the Nokia N96 (see Matthew Postgate's post below). We anticipate rolling out audio on demand to other portable devices soon.

Will this change where and when you listen to radio? Do let me know by leaving a comment.

Our catch-up TV offer just got a whole lot smarter, thanks to the introduction of the series stacking feature on 大象传媒 iPlayer and programme sites on bbc.co.uk.

We first announced this during last month's Edinburgh TV Festival [see earlier post], where we also talked about plans for live streaming of the 大象传媒's TV channels - all part of making our programmes and channels available when, where and how audiences want them.

Series stacking, which starts rolling out this week, extends the availability window of selected series from the standard seven days to the lifetime of the series while on air, up to 13 weeks after transmission of the first episode.

It might seem like a difficult concept to get your head around but the reality is altogether more simple: you can now feast on multiple episodes from the same series for longer.

Unlike a , which requires viewers to know what they want to record in advance of it being shown, stacking lets you join a series part way through its run and catch up not just on the most recent episode, but on earlier ones too.

We expect that this will appeal most to viewers who've heard about a series from friends or colleagues, or read about it in the papers, and can now go back to the start and see it all the way through.

We also expect that many of the programmes already available for seven-day catch-up on iPlayer will prove as popular when offered for longer as a series stack. While viewers can look forward to stacked episodes of their favourite comedies, dramas and factual programmes, we're also hoping they'll be able to enjoy a broader range from across our channels and genres. Imagine, for example, being able to watch a series helping you to learn a new language or skill, at your own pace.

Not everything will be stacked: the offer is restricted to 15% of all content offered on demand, something the 大象传媒 Trust determined in its permissions and approvals, granted in April 2007.

We'll be stacking just first-run series and we've also taken the decision not to include soaps, news bulletins, review-based programmes and single events - because of the types of programmes these are and, for the first two categories, the number of times they're on every week. We'll also be excluding programmes containing material of a legal nature, such as Crimewatch - in case this could prejudice court proceedings.

Series stacking will initially be available for streamed programmes on 大象传媒 iPlayer and via bbc.co.uk programme sites. My colleague Dan Taylor discusses more about what we're doing on these here.

We're working on extending this to downloadable programmes and the iPlayer for TV platforms (currently available to all Virgin Media customers). I'll post again when these are ready to go.

This isn't a true Long Tail offer, as we're merely extending the availability of stacked series for slightly longer than the standard seven-day catch-up window.

But it will be interesting to see how this stretched availability window resonates with audiences and helps them discover not only programmes they might otherwise have missed, but also more episodes of both what they already enjoy and those hidden gems.

We're always keen to hear about what you think of the 大象传媒's evolving TV on-demand offer, so please use the comment box below.

Editors' note: This is a post based on an article in this week's edition of Ariel, the 大象传媒's in-house weekly magazine, by Audio & Music Interactive's Head Of Distribution Technology John Ousby. It includes John's images from the , as blogged at .

Dr , the founder of , was unfortunately upstaged at his own keynote address at IBC in Amsterdam last Friday.

Google and YouTube are parasites. It's all about content; the rest is just railway lines.

This was the message given by ITV boss in his recorded interview included in the session. A few people in the audience started clapping until they realised they were outnumbered by the growing army of raised eyebrows.

Were we in a conference from the late '90s? Or did this have anything to do with the fact that ITV is later this month?

The idea that content can be easily separated from technology and distribution is plain wrong. One has been informing the other since the start of broadcasting, through the production technology available at the time or the way audiences find, share, discuss and consume it.

The biggest mistakes I have seen in the broadcast world are when interactivity is slapped on once the paint is dry in the production process or when a technology application is created without consideration of the audience it is intended for.

You can't spend much time at IBC without hearing about convergence and the ever-redrawn battle lines between content owners, broadcasters, internet service providers and telcos.

was around mobile TV [], which on the broadcast side hasn't had the most prestigious start after several years of hype, trials and struggling commercial services.

Mobile operators have struggled with small volumes of low quality video clips in walled gardens that are expensive to consume and unreliable in reception. With mobile services, context is everything - not just the web (or telly) bundled across to a smaller screen, but content which takes account of where and how it is consumed, and by whom.

You could draw the conclusion that video on the move just isn't as important as was thought. I believe it's just a question of when.

We are in a transitionary phase where we are just starting to see the possibilities for mobile video once it's made easy to consume and the pricing structure is relatively understood, as with the iPhone.

Let's just start to think about mobile video and audio, of which TV is a subset rather than a starting point - both broadcast- and internet-delivered video have a part to play in the future of mobile TV.

looks like anything else on display at IBC until you understand what it's doing. Live p2p video streaming based on the tribler infrastructure - a potential solution to iPlayer success... Great project involving 大象传媒's George Wright, and the among others. Of course, not just video can use this. Nice work.

Walking the halls at IBC proffered the usual mix of landmark moments, promising new technology and the next biggest, brightest display screens, some of which can be seen in .

It made me proud to see that the 大象传媒 were involved in a lot of the best of show - DVB-T2 (next generation digital terrestrial TV delivery), Super High Vision (HD on steroids) and p2p-next (live peer to peer streaming), to name a few.

Let's just hope that next year can see a keynote fit for 2009 not 1999.

DVB-T2 - rotated constellations (256 QAM): 大象传媒 has been leading the work of the DVB group in its next generation DVB-T work. DVB-T2 gives about 50% extra capacity than DVB-T and will be essential for Freeview HDTV services - currently planned for the end of 2009. More detail here: dvb-t2

Today is a big day for 大象传媒 television on the web with the launch of brand new websites for 大象传媒 One, 大象传媒 Two and 大象传媒 Four as well as an updated 大象传媒 Three site (building on February's relaunch) and a new TV homepage.

It also heralds the switch on of live streaming (simulcast) for 大象传媒 Four, C大象传媒 and CBeebies, joining 大象传媒 Three, 大象传媒 News and 大象传媒 Parliament, which are already available to watch live online, with 大象传媒 One and 大象传媒 Two due to follow later this year [see recent press release and previous multicast trial].

Last but by no means least, today also marks the passage of /programmes from beta to fully
fledged live service, boasting a permanent, findable web presence for every TV and radio programme that the 大象传媒 broadcasts.

A lot of things to launch all on one day? Unquestionably, but it's indicative of the increasingly interconnected nature of the 大象传媒's online offer, where the channel websites are no longer discrete content areas, but are fully integrated with the wider programmes offer and beyond.

So, how did we set about redesigning (and hopefully improving) some of the most visited pages on bbc.co.uk? Well, we started with your feedback on the previous sites, collected via the bbc.co.uk Pulse survey, which told us that the basic tasks of finding out what's on television and quickly locating information on specific programmes were most important and could be made easier.

With this in mind, we placed a schedule carousel along the top of the new channel homepages and a snapshot of what's on now and next across every 大象传媒 TV channel at the heart of the new TV homepage. We also added a Programmes A-Z module to the top right of all of these pages to provide quick access to the wealth of programme information housed within the newly minted /programmes.

A significant development since the channel websites were last refreshed (in July 2007) is the availability of catch-up programming via 大象传媒 iPlayer, which we've reflected via a dedicated module on each of the homepages, showcasing the most popular programmes on demand with a link through to the full iPlayer offer. iPlayer availability is also reflected in the schedule carousel with a Watch Now button appearing for programmes which can be viewed on demand and Watch Live buttons for those being simulcast.

The eagle-eyed among you might notice that the channel homepages have a discreet temporal metaphor to them, with past programming on the left of the page, the present reflected in the centre, and future highlights to the right, reflecting the expanding life of programmes beyond a single moment of transmission (for more on this topic, check out ex-大象传媒 staffer Dan Hill's blog post on ).

Lower down on the homepages, you'll find links to top video clips, photo galleries and "Be on a Show" information, as well as channel-specific elements such as 大象传媒 Four's Newsletter and comments forums.

Of course, it's not all about the homepages. Behind the schedule links are full TV listings for each of the channels (including regional variations), which are fully integrated with /programmes, meaning they will they will be permanently accessible, unlike the What's On What's On listings (which these will replace) which became inaccessible after just two days.

Each channel site also has an area for channel trailers (known in the industry as ), compiling the stings that appear between programmes on 大象传媒 One, 大象传媒 Two, 大象传媒 Three and 大象传媒 Four.

Far too many people have contributed to the above projects to list them individually; suffice to say it's been a truly pan-大象传媒 effort with colleagues from Vision, Audio & Music and Future Media & Technology all collaborating to raise the bar for the 大象传媒's programme and channel support online.

We're really keen to hear your feedback on the new sites, so please leave a comment below.

At , Jeremy Kirk has a detailed feature called 大象传媒's iPlayer Takes Online Video Programming To The Edge, with lots of quotes from iPlayer nabob Anthony Rose, stats and DRM observations:

But over the last 10 months, the iPlayer has seen major upgrades to the way it can deliver video, video quality and compatibility with an ever-expanding number of mobile devices, putting the iPlayer on the forefront of Internet video delivery. The 大象传媒 is solving many of the problems with online video delivery that have vexed other services around the world.

There's also a to iPlayer from Audit Bureau of Circulations chief exec Chris Boyd in Media Guardian:

I love the iPlayer; I just think it's amazing. About two years ago I tried to use the ITV equivalent, which would never download, and then over Christmas my daughter and I wanted to watch separate programmes at the same time and a friend of hers told her that the iPlayer was very good. Since then I've used it pretty much every week.

I promised you an update on numbers after the Olympics and here it is. The statistics are endless and with the analytics tools at my disposal I could prove that I am the rightful King of Sheba, so I'll just give a summary of some key messages.

Overall we served approx. 50m sport video streams during the Olympics. This averaged out at about 3m per day, but peaked at 5.5m on Tuesday 19th August. There were many athletes you were interested in and Chris Hoy and the cycling team, Rachel Adlington, Christine Ohuruogu, Usain Bolt and Michael Phelps were all athletes that generated large audiences.

As an example of what people were watching, here's what people watched (ie, started a video stream) or read (ie, viewed a web page) on Wednesday 20th when was :

• 200m : 914,543
• 200m video: 501,943
• 200m heats : 61,257
• 100m video: 54,357
• 200m heats video: 42,986
• 200m interview video: 33,500
• 100m : 33,500

We found that as much as 45% of the Olympics audience engaged with video from the Olympics site. The trend is more interesting in that in general you were keen to engage with video. Looking at how we promote AV, how we create clips and how we deliver them are all things to build on from the Olympics.

For example, the opening ceremony live stream was embedded on the News and Sport front pages, as well as the Olympics index. Around 80% played the stream on the Sport indexes, while 50% played the stream on the News index. In general, a quarter of the traffic which came to the Olympics site from the UK watched video (that is, those in the UK who can access the geographically rights-restricted streams).

My favourite statistic is that you watched nearly 9.7m hours of Olympic video on the website (yes, you did!) and regularly there were over 100,000 watching at the same time though the peak stayed at just under 200,000 across live and on demand videos.

How do the online and TV viewing experiences compare? Well, online you watched live video for about 15 minutes per day, and dipped in and out of on demand clips for about 3mins20sec per day. TV figures are in Roger Mosey's post here.

The Chinese can't get enough of the Olympics, like they don't want it to end and it's interesting to note that even though they could not see the video, there was a large international audience on the 大象传媒 Olympics site, some watching the live text updates, some looking for story details.

As well as the glamour of the Olympics, day-to-day news gathering carried on and also on Wednesday 20th, we served 2.7m news AV clips, with a peak in demand following the Madrid plane crash.

These are all amazing figures and if you are interested in comparing different countries in Europe and how they engaged online, you can start by looking .

So another lesson? If this blog post had video in it, more of you would have read it... perhaps.

Thanks to you for enjoying the Olympics with us so much. Now go ... you can get back to work in October.

John O'Donovan is Chief Technical Architect, 大象传媒 FM&T Journalism.

The 大象传媒 World Service Trust uses the creative power of the media to achieve development goals. We use a variety of approaches including television and radio drama and advertisements to raise awareness and promote change in behaviour on health, governance, human rights, the environment and other development issues.

We were recently given a tough task: to make condoms more acceptable, and free from negative judgment, in a country that doesn't really acknowledge that sex happens, never mind sex that should be protected.

We came up with a wacky idea to get people talking about condoms. We recorded a condom-themed ringtone. Listen to the mp3 here.

This is, we think, the first time that a mobile ringtone has been used to communicate a social or public health message. With one in four people in India having a mobile phone, and ringtones being, for some, statements of personal style, it's a new way to reach people.

We also decided to use a ringtone because, when the phone rings, the tune - or, in our case, the word "condom" - is put out in public. This stimulates conversation, which is desirable as - according to research - those who talk about sex and condoms are more likely to have healthy behaviours, such as using condoms consistently.

We wanted to create a conversation piece that would get people talking and would ultimately help to break down the taboo about condoms. We want to portray the condom user as a smart and responsible person. Having the ringtone on your phone shows that you understand this.

Setting up a true tone ringtone

There are three ways of setting up a true tone ringtone download service:
? IVR: Interactive voice response is a voice service where the mobile user dials a code, hears the ringtone and has the option of selecting the option to download the ringtone
? SMS: the mobile user sends a code word (e.g. "CONDOM") to a shortcode (in our case it was a seven-digit numerical code) and gets a WAP push in reply, from where the user has the option to download the ringtone, at which time download costs apply
? online: the MP3 file posted on an internet site allows the user to save it on his/her computer and then transfer it to his/her mobile telephone.
In addition to these, the ringtone can be shared via bluetooth and emailing MP3 files.

As cost was a priority, both for minimising our costs and the cost to the mobile user, we selected the SMS and online options. We tried to negotiate the SMS download for free because this was a non-profit public awareness campaign, but with India having many telecoms companies and operators, this was an impossible task, which meant that a free download from a website was just as important as the SMS download.

The dedicated website is at and also has condom-themed games and details about the campaign.

Through the SMS option we were able to capture most GPRS and all CDMA providers in the country. The arrangement with our service provider is that the download costs nothing to 大象传媒 World Service Trust, but costs 3 Indian Rupees (INR80 = 1GBP) for the request SMS and between INR10-20 for download from WAP push.

A shortcoming of this approach is that only people with true tone-enabled mobile phones can download the ringtone. As we've witnessed, people don't even know what their phones enable, as evinced by the vast numbers of people who have requested the download but have not been successful because their phones do not support the true tone ringtone.

We've debated whether to produce a polyphonic version, but decided it defeats the purpose of the getting the word "condom" out.

The ringtone is being promoted in TV and radio adverts. You can see the TV ad on the Trust's website or below:

Much to my excitement, the idea to use mobile telephone ringtones to influence views about condoms has not only gripped India, it has now become an .

The campaign started just a month ago and here are a few topline results:

• We've had over 270,000 requests for downloading the ringtone in India through our SMS shortcode. This does not include the number of people who have obtained the ringtone via Bluetooth and our website.
• The campaign website condomcondom.org has received over 2m hits. We get over 65,000 hits a day.
• We've collected hundreds of news stories from all over the world that have covered the campaign. It's appeared on the front page of the as well as international media. International sources covering it range from and to the very random - I was recently interviewed by a radio station in Bogota Colombia!
• The Indian government has adopted our campaign and is airing our TV and radio adverts at its own expense as part of its National AIDS Control effort.

We are tracking all of the media and to the campaign, specifically to assess the impact this has had on people's attitudes towards condoms.

I'll leave this post with an amusing (and completely true) anecdote. When we were recording the ringtone in a Mumbai studio, the shape of the audio wave file on the computer screen was unbelievable, uncanny. Have a look:

With this "condom normalisation" project, we've added a new device to our tool kit - the mobile ringtone!

We're taking in bringing 大象传媒 iPlayer to mobile audiences, or as The Times :

Lying in bed watching the latest episode of Strictly Come Dancing on a mobile phone will become possible from next month after a tie-up between the 大象传媒 and Nokia.
All 大象传媒 programmes transmitted in the past seven days will be available to download to the new Nokia N96 multimedia handset, in a first for the broadcaster and phone maker.

N.B. 大象传媒 News also has the story (ed)

Mobile can be a complex environment and there is a great deal of fragmentation to contend with.

I have always wanted to take 大象传媒 iPlayer to mobile but we have been waiting for devices to arrive which mean we can create the kind of experience that audiences have come to expect from the service.

The iPhone and iPod Touch gave us something to work with and we launched a beta for those devices earlier in the year. Some aspects of the experience were fantastic but there were still compromises. The was always gong to be a contender, as we knew it would be optimised for video and audio. The success of the also meant there was a good chance of it becoming a mainstream device.

Nokia were keen to work with us on the project and together we looked into what it would take to launch something. It proved to be the first platform where we could fully realise the ambition that we had for mobile iPlayer. Naturally, we will want to introduce other devices as they become available - and we're already working on the next group.

It will be interesting to see how people use 大象传媒 iPlayer on mobile rather than over a set-top box or a computer. I think that the ratio of download to streams might be more, even compared to the PC; I also think that 大象传媒 radio programmes will perform well. No doubt there will be some surprises that we will be able to feed into the next version.

As ever, any launch is only the beginning of the journey and now we have the core functions of iPlayer available we will begin to see what the mobile version can do uniquely well. Social features seem an obvious choice but there is a possibility for something around location. Ultimately, we want the mobile version to make a contribution to a 大象传媒 iPlayer that is greater than the sum of its parts.

Getting the show into HD is a key part of trying to make good our promise that we'll bring you the very best programmes that the 大象传媒 has to offer across our channels in HD. Like him or loathe him, JR is undoubtedly the best in class when it comes to that kind of entertainment.

I hope that you will find other innovations through the autumn in a number of programming areas, and can also tell you that 大象传媒 HD will be on air for longer. We'll be starting our schedule at 7pm on weeknights and earlier at the weekends throughout September and, I hope, further increasing the hours toward the end of the year.

Finally, I've started some work to look at the question of DOGs to help me to make a decision about what we should do on a subject I know many of you feel strongly about. No promises as to the outcome, but I wanted you to know that it's underway.

Imagine for a moment that it's January 2008 and that (The Digital Video Broadcasting Project) is currently drafting a called DVB-T2 for the next generation of digital terrestrial television transmission (DTT) systems.

For Freeview to remain competitive against other competing delivery channels, such as satellite, cable and in the future IPTV, it has to be able to deliver High Definition content to viewers who now increasingly have HD-ready large flat panel displays in their homes.

So DVB-T2 is a key enabler for DTT, Freeview in the UK, to be able to deliver HDTV services.

So... back to that day in January 2008.

There are about 30 emails every day on the DVB-T2 email reflector as people from all over the world discuss detailed technical aspects of what should be in the specification.

Simply reading these emails is a full-time job in itself.

Ofcom has published the result of its on the future of digital terrestrial television. It says that at the time of digital switchover,

one multiplex should be cleared of existing services in order to be upgraded to the new technologies, MPEG-4 and DVB-T2.

In the broadcasting world, there are two major trade shows each year. The first is in Las Vegas in April and the second is in Amsterdam in September.

Now we knew that the specification was on its way and we had two ambitious goals:

The first was to have real DVB-T2 compliant signals on air as soon as the was approved by DVB (which is expected to be in either March or June).

The second was to show a live real-time end-to-end chain consisting of High Definition (HD) source material, a DVB-T2 modulator, a DVB-T2 demodulator and an MPEG-4 video decoder showing pictures on a large HD display at IBC in September.

Remember it's January 2008 and at this point we have... nothing.

The first goal was to produce a modulator so that we could begin transmissions at the same time as the specification is approved.

We also needed to work with our transmission partners and in order to find a suitable transmission site and to install our transmissions equipment there, as well as applying for a transmission licence from Ofcom. After considering many factors, such as the availability of a suitable frequency, was chosen.

The main development task for us in 大象传媒 R&I was to produce a modulator. We needed to build both the hardware and the ().

In order to produce a in the short time available, we opted to use a .

This meant that in hardware terms, we only had to build an interface card and a box to put it in. The photo below shows the prototype modulator we developed. The hardware was developed by one of my colleagues Martin Thorp.

In June we visited Guildford transmitter to install our transmission equipment. The picture below shows the inside of Guildford transmitter hall with our equipment installed in the rack.

We then made a few spot measurements around Guildford to verify that the signal was being transmitted as expected.

The picture below shows Martin (right) and me (left) receiving the first test transmissions from Guildford.

On the day that the specification was approved by DVB (26 June 2008), we issued a press release to tell the world that we had begun the world's first experimental DVB-T2 transmissions.

Immediately after the press release went out, I had to do a series of press interviews about what we had done. I even did one of these by phone on my summer holiday from America.

The next stage was much more difficult. We had to build a demodulator in time for IBC in September (two months away).

Now, a demodulator is much harder than a modulator. The specification tells you exactly what signal to transmit, so "all" you have to do is build a piece of equipment that codes the signal in the way defined by the specification.

When you build a demodulator, you have the problem that the signal will not be as good as when it was transmitted (it could be subjected to noise, multipath or interference for example). So you have to build your demodulator to cope with all these problems. You also have to design algorithms to receive the signals at all.

As with the modulator, we opted to use a FPGA () development card. However, due to the additional complexity of the receiver, we needed to use two of them.

Again, my colleague Martin organised the hardware (including building an interface board) while I was on holiday in America.

The result was that when I came back, he had built the receiver shown in the photo which was a perfect hardware platform on which to develop the receiver firmware. The date was now August 4 and I knew that I was going to have to put in long hours to develop the demodulator. So my wife and kids went to visit their grandparents in Tenerife for a couple of weeks. During this period I was working seven days a week from 10am to 2am. Oliver Haffenden came in at the weekend to help me with the algorithm development work.

In parallel to this work, Chris Clarke had developed a 32K FFT and BCH decoder and John Elliott had developed an LDPC decoder.

The good news is that by the time my family got back, we were viewing rotated 256-QAM constellations in the receiver [see picture]. This was a very encouraging sign.

After several more days of long hours, we finally achieved a working demodulator. Entirely by coincidence, we achieved the first working demodulator on the day of the 60th anniversary of the R&D Department at Kingswood Warren.

This meant that many of our senior managers who were our site for the anniversary were able to have a full demonstration of DVB-T2.

In order to have some high definition material to show at IBC, we coded some new material with the latest MPEG-4 encoders (which looks fantastic to me) and obtained rights clearance to use the material.

So at the end of this week, we will be packing up the demonstration and shipping it to Amsterdam to demonstrate at IBC. If you're there, please come and visit me on stand 1.D81 - we're looking forward to showing you the world's first end-to-end DVB-T2 modulator / demodulator chain.

The Archers is a radio soap opera - "an everyday story of country folk" - that has been running for more than 15,000 episodes since May 1950. What I find particularly intriguing about The Archers in terms of the future of radio is that it is, in a way, happening in real time.

Every evening on Radio 4, the programme contains events that happened (approximately) "today" in - so if it's Easter in real-life then it's Easter in The Archers. It's also very topical - featuring real-life events such as outbreaks of foot-and-mouth disease or the World Cup. As a drama, each episode is split into distinct scenes - typically indicated by a fading to silence - a convention for audio drama because of its need for clear signposting. The other interesting aspect is the many distinct facets of each scene - which characters are involved, the time of day, the current location, the storylines that intersect at that moment and even the weather.

So, earlier this year, the Radio Labs team started to design and build a prototype website for The Archers based around the drama's scenes and facets.
