H.264 Video Coding Algorithm Research And DSP Realization

In the emerging communication system, research on fast coding algorithm is the key technology for improving video quality. It has been a hotspot project of application to video communications in recent years. H.264 is the latest video coding standard developed by the Joint Video Team (JVT) which is formed with ITU-T Video Coding Experts Group (VCEG) and ISO/IEC Motion Picture Experts Group (MPEG) in 2003. H.264 is a new developing video coding standard, as MPEG-4 part10, and it aims at proposing a high quality and low bit rate video compression standard by researching into the existing coding technologies. H.264 has been the focus in the video compression area, it has a promising future in digital media market. So it is important for engineering application and theory to research deeply into H.264 and the implement of its fast H.264 encoder.This dissertation mainly research on the new techniques in H.264/AVC. First the author describes the history of video coding, then introduced the H.264/AVC standard in detail. In succession, the author mainly researched some algorithms in Intra-frame and Inter-frame. For Intra-frame, emphasized on pattern selecting algorithm, especially those fast algorithms, and I also gave a new algorithm with a good effect. For Inter-frame, the emphasis was motion estimation, especially those fast searching algorithms. I also gave a improved algorithm in fast searching and gained good effect.After having researched some algorithms in H.264, I emphasized on realization of H.264 encoder. DSP is a good plat for it, I researched naturalization and optimization in DM642 flat. In the last, I accomplished some task and gained a good effect.
