Efficient redundant frames encoding algorithm for streaming video over error prone wireless channels

The H.264/AVC coding standard only specifies the decoding process and the bitstream syntax to allow considerable flexibility for the designers to optimize the encoder for coding performance improvement and complexity reduction. This paper proposes the use of redundant Predicted (Marionette) frames to prevent temporal error propagation in H.264/AVC streaming over error prone wireless channels. Compared with the H.264/AVC conventional redundant slices technique, our proposed approach can effectively enhance the smoothness of the video. A visual quality comparative study has been also carried out in order to validate the proposed approach.
