Title
Algorithm and architecture design of multi-layer video coding enginewith hybrid scheme for wireless video links
Abstract
For a wireless linking system, the bandwidth might be limited. Therefore, it needs a codec to compress the data transmitted in the system. However, tranditional video codecs can not be used directly in the wireless linking system because there are several requirements in the system. First, the codec should support various applications. Second, low latency is required for real-time applications. Third, error robustness is important in the wireless linking system. In this paper, a coding engine with hybrid scheme for wireless video links is proposed. It consists of two codecs which are JPEG-LS and H.264 intra prediction to process various applications and provides two type of bitstreams for wireless bandwidth variation. 20% of hardware cost is reduced by putting mode decision in front in the proposed encoder. The proposed codec is error robust by not using temporal information and has a low latency of 1.84us by macroblock pipelining architectures. The processing capability of the proposed architecture achieves Full-HD 60fps.
