In this information age, a efficient video encoding/decoding technology will help reducing information redundancy, delaying processing, enhancing the robustness, improving visual perception of quality, increasing the compression ratio, etc. At first, this article describes the history of video encoding/decoding standards development. Research on the key technologies of H.264 coding standard currently...
Video coding standards (e.g. H.264, HEVC) use slice, consisting of a header and payload video data, as an independent coding unit for low latency encode-decode and better transmission error resiliency. In typical video streams, decoding the slice header is quite simple that can be done on standard embedded RISC processor architectures. However, universal decoding scenarios require handling worst case...
In this paper we explore a method to encode/decode multiview textures and associated supplementary data (depth map as an example) together in a single bitstream. Least significant bit (LSB) of last two levels in each transform block has been modified according to the depth encoded bits, thus resulting in very minimal loss in PSNR of textures (0.1 – 0.5dB) with overall bitrate gain of about 13% for...
