Abstract:
This is a complex problem, with several causes and fewer solutions. From production to broadcast, there are many points in the signal path and postproduction process where lip sync can either be properly corrected, or made even worse.
This session’s panel will discuss several key issues. Where do the latency issues exist in postproduction? Where do they exist in broadcast? Is there an acceptable window of latency? How can this latency be measured? What correction techniques exist? Does one type of video display exhibit less latency than another? What is being done in display design to address the latency? What proposed methods are on the horizon for addressing this issue in the future?
Join us as our panel covers the field from measurement, to post, to broadcast, and to the home.
