SMPTE Asks Industry for Lip-Sync Error Information

SMPTE has announced an open call for film and video industry professionalis input on the ever growing audio-video synchronization errors. According to SMPTE, they have formed an Ad Hoc, Lip Sync Issue group designed as a resource and solution for the broadcast industry. The SMPTE is requesting information from broadcast professionals on such topics as MPEG encoding delay issues, in-service measure methods, or any other area where lip-sync errors occur or can become problematic.

"SMPTE is particularly interested in hearing from manufacturers with practical solutions or proposals for measurement and correction of audio-video synchronization errors, and those willing to participate in development of related standards."

You can find more information about the SMPTE standards at the group Web site. Responses should be sent in the first instance, and as soon as possible, to the ad hoc group chair, Graham Jones of NAB.
