Intelligent error resilient video encoder |
摘要 |
A method and apparatus for compressing video data to improve its tolerance to error, especially with a low bit rate network. With this invention video data is divided into a number of frames and each frame is divided into a number of macroblocks. A dependency count is assigned to each macroblock, and if the dependency count for the macroblock exceeds or is equal to a threshold, the dependency block is intra-coded using low bit rate coding algorithm. If the dependency count is below the threshold, the macroblock is inter-coded.
