Systems and methods for error resilient encoding
WO 2002071639 A8
Abstract
The present invention is related to error resilient video encoding. Embodiments of the present invention provide systems (Figure 1B, 100B) and methods for reducing error propagation in a video data stream, for refreshing macroblocks, for reducing frame rates in a video data stream, for generating error correction information for a media stream, for performing bit rate allocation for a video data stream, and for detecting scene changes in a video data stream.
