NBA Conference Finals in sync thanks Sigma
Turner Broadcast Systems has purchased Sigma’s Arbalest digital audio-to-video synchronization systems for use in the upcoming NBA Conference Finals and all other live-to-air broadcasts.
The Arbalest system is designed to end lip-sync errors created when video and audio signals are sent through multiple transmission systems before hitting the air. The system automatically detects and compensates for any delay in a transmission up to plus or minus five seconds between a video signal and a corresponding audio. The process is totally transparent to viewers, and uses a patent-pending processing system that accurately identifies the time relationship between video and audio signals.
Sigma has been working on the system since 2004 but the first production models just became available this April. Bill Swilley, president of Sigma Electronics, says the system is a dependable, verifiable way to ensure that the picture and sound captured during a live broadcast reaches the studio perfectly synchronized.
