The invention relates to a method for eliminating errors in compressed video transmission. A method for eliminating errors in H.264 compressed video transmission is disclosed, to eliminating errors in a simple and efficient manner. In the invention, an error information feedback mechanism is used in combination with error concealment and error propagation suppression to eliminate errors. An error is detected and statistics of error information, such as position of lost data, is obtained by sequence numbers of NALUs and information for carrying slices. An error information feedback channel is established in H.264 architecture by defining an extended SEI message. The error propagation is suppressed by segment-wise intra-coding in batches.
