A method of inserting binary data into MPEG bitstreams

摘要

We propose a method for inserting binary data into MPEG bitstreams. The proposed method allows us to extract the inserted data perfectly eventhough the MPEG video is a lossy algorithm, and the quality of the decoded images after extracting additional information is almost the same as that of the ordinary MPEG bitstreams. Moreover, the standard MPEG decoder can be used for decoding the bitstreams with inserted binary data. In that case, the additional binary data remains in bitstreams but can decode images without obvious image degradation. To verify the effectiveness of our method, we show simulation results using BIFS (BInary Format for Scenes) data for MPEG-4 as an example of the binary data for insertion.
