He talks about how he got into the profession, the demands on his family life as he spends months covering cricket, the grind of setting up before a cricket match, memorable on-field moments that he has covered amongst other things. Welcome to the show, Hari! Hari Surendhra— Thanks, Subash. Glad to be here.
Hawkeye: Hawkeye Innovations, based in Basingstoke and owned by Sony, was founded by Dr Paul Hawkins and first used by Channel 4 for its cricket broadcasting during the Ashes.
It will now provide goal-line technology in football.
It is also used in Australia, where cricket rights are owned by Channel 9. Audio: The audio is provided by the broadcasters and originates from sound picked up by microphones in the middle stumps at either end. It was originally invented as a broadcast tool but improvements in audio technology have seen it added to the DRS.
A new updated snicko is being trialled during the Ashes. Entitled Real Time Snicko it is quicker to process. At the moment snicko is not part of DRS due to the length of time it takes to match up the audio to the visual images.
Hawkeye: Takes out the guess work for umpires by using up to seven cameras which track the ball from different angles. The video is then triangulated to create a 3d image and uses the same predictive technology utilised in the launch of rockets.
Hot Spot: It can prove if the ball has struck by the bat. Its thermal imaging detects heat which is caused by the friction between the ball and the bat.
It can show up edges not audible. Audio: Umpires can use sound if Hot Spot fails.
Snicko: The soundwave readout is analysed graphically once the moving image is matched with the audio picked up from the stump mics Cons? Hawkeye: It is predictive and there have been suggestions it is not accurate.
It is not used unilaterally.
There is a rival company, Virtual Eye which provides the technology in Australia. Hot Spot: Sometimes fails to detect faint edges from fast bowlers due to lack of friction.
Audio: The stump mics pick up audio from batsmen, bowlers and fielders which can distort the sound of contact between bat and ball. Snicko: It takes too long for the evidence to be collated in time for the DRS. Again, the sound can be distorted by other noises. Hawkeye: Unquestioned and used as normal by the 3rd umpires and players appear to have trust in its use.
Audio: Used by 3rd umpire as evidence for edges even though there has not been any Hotpsot marks. Snicko: Nothing as it is only used by the broadcasters and not the 3rd umpire.
