Symetrix Delays Yahoo

San Rafael, CA (December 13, 2010)--Yahoo! has installed two Symetrix Jupiter processors to manage video signal delay at its sports broadcast facility.

San Rafael, CA (December 13, 2010)–Yahoo! has installed two Symetrix Jupiter processors to manage video signal delay at its sports broadcast facility.

The Yahoo! sports broadcast facility, which produces original webcasts, including Fantasy Football Live, recently upgraded its video equipment to high-definition (HD). Systems integrator, Snader and Associates (San Rafael, CA) performed the original upgrade and returned to install two of Symetrix’ new processors between the facility’s audio router and its soundboard. After the analog sunset switch to HD, latencies in the new system led to unacceptable delays in the video signal relative to the audio signal. The eight-input, eight-output Symetrix Jupiter processors handled the delays and provide Yahoo! with spare processing power for future upgrades.

Snader and Associates helped assemble Yahoo!’s sports broadcast facility back in 2000, and was called back to swap out existing equipment for an HD path and a new switcher. Nevertheless, some of the facility’s standard definition workflow had to remain in place. “We were all aware that there would be some delay issues with up- and down-conversion,” said Snader engineer, Nicholas Smith, “but these were worse than we expected and, perhaps more importantly, the delay times were inconsistent and depended on which combination of cameras and devices were used for a particular broadcast. That meant we couldn’t simply slap a fixed delay on the audio and call it done. The situation called for more nuance.”

The Symetrix Jupiter series is inspired, in part, by smartphone technology. Users download an app that meets the requirements of their sound system from the Symetrix website, and the Jupiter hardware is immediately and appropriately configured. If needed, users can tweak setting from a programming interface. For Yahoo!, Smith used the Sound Reinforcement 2 app, which allowed the client to route audio sources through the Jupiter and adjust the delay to match the video.
