The Research of H.264/AVC Video Encoding Parallel Algorithm

The research of H.264/AVC parallel algorithm should be on the condition of not influencing video quality and encoding rate. Through the thorough comprehension of encoding principle and bit-stream structure, this thesis designs a H.264/AVC video encoding parallel algorithm, considering four factors about encoding rate, load balance, system architecture and node state. Video sequence is divided into many independent units of group of picture (GOP), and then they are processed by different nodes synchronously. At last connect the processed bit-stream correctly according the original bit-stream structure. From the results, we can find that it is exactly the same that the data of video quality and encoding rate, which are obtained from the serial algorithm and this parallel algorithm, and it is possible to speed up the encoding process considerably on the system architecture of cluster.
