Turner Broadcasting System has ordered Sigma Electronics' Arbalest Digital audio-to-video synchronization systems for use in live-to-air broadcasts. The initial order was used for Turnerâ€™s TNT Cable Networkâ€™s broadcasts of the NBA Conference Finals.
The Arbalest system provides recovery from lip-sync errors created by multiple video and audio transmission paths. In development since 2004, the production model was shown last April at the NAB conference and exhibition in Las Vegas.
The Arbalest automatically detects and compensates for any delay in a transmission up to +/- 5 seconds between a video signal and corresponding audio. The process is transparent to viewers, and uses a patent-pending processing system that accurately identifies the time relationship between video and audio signals.
