The Research On A Universial Video Coding About Compression Algorithmic In Shot

With the rapid development of information technology, multimedia information business people on the ever-increasing demands. Although people in their efforts to increase access bandwidth and improve access speeds , but the multimedia data compression technology is still widespread concern High compression ratio of the video coding has become the current field of digital signal processing one of the hot issues.The existing video compression is mainly based on the frame of compression, that is, intra-frame compression and the adjacent compression, Through intra-frame compression and adjacent indeed can greatly compressed video data compression, but it ignore the situation in no neighboring frame compression. With the development of video compression, the compression of the redundancy of the no-adjacent frame is very necessary.This paper studies the redundancy of not adjacent frame in video, video shot redundant. A repetition of the shot compressed to enhance the video compression ratio. Through theoretical analysis, verify the feasibility and effectiveness of the shot compression algorithm. This article is based on known video-compression of the border, made by detecting the key Frame of shot to compare the two shotes are redundant, so the shot of the video can be compressed. As video shot at scene of redundancy is often redundant and therefore this paper, "sliding window" approach to reduce the compression algorithm of the time complexity.By design DirectShow filters on the shot there redundant video data compression. By design DirectShow filters on the shot there redundant video data compression.The results show that support DirectShow codecs in the video encoding format, the existence of the video shot redundancy,to achieve good compression effect. The compression ratio of the test video is up to 1.06: 1...
