Abstract:
Lip sync remains a complex problem, with several causes and few solutions. From production through transmission and reception, there are many points where lip sync can either be properly corrected or made even worse. This session’s panel will discuss several key issues. What is the perspective of the EBU and SMPTE regarding lip sync? Are things being done in production that create this problem? Who is responsible for implementing the mechanisms that ensure lip sync is maintained when the signal reaches your television? Where do the latency issues exist? How can the latency be measured? What are the recommended tolerances? What correction techniques exist? How does video display design affect lip sync? What factors need to be accounted for in Digital Audio Workstations when working with external video monitors in a post environment? Join us as our panel addresses these questions and yours.
