Turner Broadcasting Orders Sigma Electronics’ Arbalest Digital Audio-to-Video Lip-sync System

Initial Units to be Used for TNT Cable Network’s Broadcasts of NBA Conference Finals

East Petersburg, Penn., May 22, 2006 – Sigma Electronics, Inc., an innovator of high-quality, cost-effective digital and analog switching, generation, and distribution products for television, radio, and cable, announced today that Turner Broadcasting System has ordered Sigma’s Arbalest Digital Audio-to-Video Synchronization Systems for use in live-to-air broadcasts. The initial order is intended for Turner’s TNT Cable Network’s upcoming broadcasts of the NBA Conference Finals in progress now. Turner Broadcasting System, Inc. is a Time Warner company.

The Arbalest system provides flawless recovery from lip-sync errors created by multiple video and audio transmission paths. In development since 2004, with input by leading broadcast and cable companies throughout its development, the production model was shown in April (2006) at the National Association of Broadcasters (NAB) conference and exhibition in Las Vegas.

"We are pleased that Turner Broadcasting has ordered our Arbalest synchronization system," said Bill Swilley, president of Sigma Electronics. "Our Arbalest system provides an answer long sought by broadcasters and cablecasters: a dependable, verifiable way to ensure that the picture and sound captured during a live broadcast reaches the studio perfectly synchronized."

The Arbalest automatically detects and compensates for any delay in a transmission up to +/- 5 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.

The result is perfectly synchronized television over the air, on cable, or anywhere else that flawless synchronization is required. The Arbalest system is compatible with all television broadcast systems and other transmission avenues including streaming applications.

In its production model, the Arbalest system processes multiple simultaneous multi-format feeds. Available video formats include high definition and standard definition; audio formats include AES audio, Dolby E and AC3.

Arbalest systems are now available for order from Sigma Electronics. More information is available by calling toll-free 1-866-569-2681, or visiting the Sigma Electronics website at www sigmaelectronics.com.
