In order to improve the quality of H. 264 video transmission, an adaptive data hiding and error recovery approach for I frame of H. 264 video stream is proposed in this paper. At the encoder for an H. 264 intra-coded I frame, the important data for each macroblock(MB) are extracted adaptively and hidden into the RTP header of the next frame by the proposed data hiding method. At the decoder, if the important data for a corrupted MB can be correctly extracted, the extracted important data will be used for error recovery; otherwise a simple algorithm is used to recover the corrupted MB. Simulation results show that the performance of the proposed approach is better than existing approaches.
