大象传媒 Television will be using the award-winning Hawk-Eye technology in
its coverage for the second year running.
Used for the first time last year at Wimbledon, and previously in 大象传媒
coverage of the Davis Cup and the Stella Artois Championships at Queens,
Hawk-Eye uses the latest camera and computer technology to track the
ball on the court.
Taking into account the trajectory, skid and compression of the ball,
Hawk-Eye produces an accurate real-time computer generated replay which
can be viewed and replayed through 360 degrees.
These graphical representations of the ball's path can be used by the
commentators to illustrate a whole host of statistics and player characteristics,
from the trajectory of a player's serve to the distribution of a player's
return.
Primarily, Hawk-Eye will be used to analyse patterns of play, highlighting
player performance and match strategy - therefore helping to explain
the game and increase viewers' understanding of the intricacies of the
sport.
A secondary use for Hawk-Eye can be to offer an alternative view on
a contentious line call decision, illustrating whether or not, according
to Hawk-Eye, a ball went out of play.
This will not be available to umpires and will only be used if a decision
has been contested by either player or occasionally where there has
been an over-rule.
Hawk-Eye will be used on centre court and number one court concurrently.
The eight primary analytical functions of Hawk-Eye for the 大象传媒 will
be:
1. Serve Direction
Hawk-Eye graphics illustrate the bounce point of serves, colour coded
by Ace, first serve and second serve
2. Break Point Analysis
Graphics illustrate the bounce point of all serves in play while the
serve is at break point.
3. Ace Analysis
3D graphics illustrate the trajectory and bounce point of all Aces.
4. Service Trajectory
3D graphics illustrate the 3D trajectory of a specific player's serve.
5. Return Hit Point
For each player, separate 3D graphics show the hit point of all returns
of serve, with each return colour coded by first serve return or second
serve return.
6. Rally Hit Point
For each player, a separate graphic showing the hit point for all
strokes (excluding serve and return) which were hit into play.
7. Rally Direction
For each player, a separate graphic showing the bounce point of all
their strokes in play (excluding serve and return).
8. Baseline Winners
For each player a separate 3D graphic shows the speed and trajectory
of each baseline winner.
There are a number of other analytical functions, such as net clearance,
strike point and height of a player's shot that may be used by the commentators
in addition to those above.
Hawk-Eye's revolutionary ball tracking technology is fast becoming
the industry standard for broadcasters around the world.
Owned by The Television Corporation Plc., Hawk-Eye was developed initially
for cricket and has been used in test coverage in the UK, Australia
and India.
Its tennis application is now being used at Wimbledon, The Davis Cup,
French Open, Australian Open, Stella Artois tournament and the ATP Masters
tour.
Hawk-Eye's technical innovation has contributed towards 15 awards in
the UK.
Hawk-Eye is also being developed for other sports including baseball.
