Abstract

A video bitstrean error resilient transcoder (100), method (300), video-phone, and video-communicator are provided wherein error resilience is implemented by verifying a syntax of a video bitstream and replacing the video bitstream between resynchronization markers with a valid syntax that is used by a decoder to produce a video sequence.
