Video compression techniques to solve reducing and removing redundant video data so that a digital video file can be effectively sent and received over a network and stored on computer disks. Now day’s lot of video compression techniques proposed. With efficient compression techniques, a significant reduction in file size can be achieved with little or no adverse effect on the visual quality. The Video Compression algorithm utilized in numerous standards (such as MPEG 1, 2 H.263) usually consists of the following steps. Motion Estimation, Motion Compensation, Discrete Cosine Transform, Run Length Encoding, Huffman Coding. Frame Difference, PCA Method. Many papers and researches are published related to these subject and some of these are taken. This paper gives the survey about some techniques reviewed and discussed from different authors. So it is very helpful to analyzed and compared with any proposed works for video compression techniques.
