Abstract
Systems and method for synchronizing audio and video signals are described. The audio and video signals are tagged in an encoder. The tagged signals are transmitted across a network. The tagged signals are analyzed to detect phase errors or lip synch errors between them. A synchronization signal is generated in response to such lip synch errors.
