Abstract

There are provided methods and apparatus for audio and video synchronization timestamp rollover correction. A synchronization apparatus includes a synchronizer for providing synchronization information for synchronizing a video stream with an audio stream during any point in a broadcast thereof irrespective of whether the video stream and the audio stream have different rollover points for their respective timestamps. The synchronization information is encoded for an out of band transmission with respect to the broadcast of the audio and video streams.
