Lip Sync Issues Bug Broadcasters, Video Producers
March 14, 2005
Washington, D.C. - The Society of Motion Picture and Televisoin Engineers (SMPTE) has released a Request for Information in order to address lip-sync errors in broadcast TV and video production.
The society says there is an increasing awareness, both in broadcasting engineering circles and in the viewing audience, that audio-video synchronization errors in broadcasting, usually seen as lip-sync problems, are occurring more frequently, and with greater magnitude, than ever before. The Society of Motion Picture and Television Engineers S22 Committee on Television Systems Technology has formed an Ad Hoc Group to review all aspects of this problem and make recommendations for solutions.
SMPTE is calling for input from interested companies or individuals, particularly relating to the following areas:
-Sources of differential audio-video delay in television and video production, post-production, and distribution.
-Audio-video delay issues through professional MPEG video encoding and decoding systems.
-Differential audio-video delay arising in consumer receiver, decoding, and display devices.
-Out-of-service methods of measuring differential audio-video delay.
-In-service (during program) methods of measuring differential audio-video delay.
-Devices for correcting differential audio-video delay at different points in the broadcast chain.
Responses should be sent as soon as possible to the ad hoc group chair, Graham Jones of NAB at [email protected].
