H.264-BASED ERROR ELIMINATING METHOD FOR COMPRESSED VIDEO TRANSMISSION

摘要

The present invention discloses an error eliminating method for compressed video transmission, and further discloses such an error eliminating method based on H.264 for compressed video transmission that error can be eliminated in an uncomplicated and highly efficient way. In the present invention, error elimination is realized by an error information feedback mechanism combined with error concealment and error propagation restraint. Error generation is detected via the NALU sequence number and the information carrying Slice, and the error information statistics e.g. the position of the lost data is analyzed. By defining the extended SEI message, the internal feedback path for the error information is established in a H.264 system. By performing intra-frame encoding refreshment for the slices divided up time by time, error propagation restraint is realized.
