Ultra low bit rate video coding for surveillance system

In surveillance systems, ultra low bit rate video coding is necessary to reduce the storage and bandwidth consumption, especially for high definition video coding. This paper proposes a new architecture to further reduce the bit rate than H.264/AVC. The algorithm of detecting the difference of the adjacent frames and skipping the static frames in the original video is proposed. Moreover, this paper presents an adaptive coding method to code the active regions with traditional slices and background with the proposed S slice respectively. The S slice contains less syntax elements than the conventional P slice. The simulation results demonstrate that great bit reduction is achieved by these two schemes.
