Lightweight Information Hiding in H.264/AVC Video Stream

摘要：

This paper proposes a new real-time information hiding algorithm on latest H.264/AVC video coding standard. The information is embedded into the Trailing Ones of 4x4 blocks during the Context-based Adaptive Variable Length Coding (CAVLC) process. This algorithm is efficient with low computational complexity. The simulation results show that the degradation of video quality is negligible, and the same overall bit-stream length is maintained. Under the simulation of different RTP packet loss channels, the embedded information can be well recovered.
