Outside Broadcast Van(OB Van)
         Heart of any live broadcast event
      Video Management
           Video Mixer :Accomodates
   the videos & graphics .
           Preview monitor & Program
    Sound Management

OB Van ( contd…)
   Video Store
         Collection of Video Tapes :
Feeds from prevoius matches.
         EVS System : used for slow-
 motion pictures and replays.
The Cameras

     16-21 Cameras around the stadium.
     Stump Camera

   super slow          Motion Camera( behind the bowler to   provide
high quality replays)

The Graphics

    Namadgi , Laptop running via TCP-IP.
     AD-HOC Machines (graphics on fall of wicket ,
       play statistics )
     Score-Ticker Machine
This technology uses a special image-processing
system that helps umpires take LBW decisions.
    How Hawk Eye Works
 Uses
        Image-processing system from Roke
     Manor Research
      Six specially placed monochrome        cameras
with 120 MHz .
     Track the ball’s entire trajectory,right from the
point where it is released from the bolwer’s hand to
the point the ball is considered dead
    Updated 100 times every second
What Hawk Eye Gives
   Gives more enhanced feed to TV viewers
   Application of Hawk Eye goes much beyond cricket.
                Virtual Advertising

           Virtual advertising is the electronic insertion of
advertising images during live TV broadcasts of sports and
entertainment events.
          In this, digital images, advertisements, and logos are
super-imposed on live video or inserted into a completed
movie or television show.
          Virtual Advertising
Virtual advertisements have to be
inserted at specific points in the video,
like the billboards on the field. So there
has to be a way to locate and track
designated insertion locations in the live
video. All this work is done is real time so
that the viewers could see the video live
with the virtual advertisements. To
locate insertion points in the video,
pattern recognition techniques are used.
These techniques analyze the video and
look for patterns in the video. These
patterns are then compared with the
stored patterns of the desired locations.
Once there is a pattern match, these
points in the video are located in replaced
by virtual advertisements.
    Virtual Spectator
The Virtual Spectator system
consists of two machines. One
is used to record live data from the
match, like score, fielders’
positions, where the ball was hit
and how high it bounced. The data-
entry operator sits in high position
to get the whole view of the
ground. The other machine is used
to provide feed to the broadcaster,
and its operator works out the
various graphics based on data
coming from the first machine.
IT Stand. and At Stand

 IT at the Stands
 Crowd-control mechanism
    Though I dicussed only about
cricket, but IT takes crucial role in
  broadcasting of each and every
              live Event.
In other words, it is concluded that
  “IT is the backbone of every live
