Abstract: This paper presents a study of various video compression techniques. A very large amount of usage of digital multimedia data through communications, internet, wireless communication and other networks has increased the growth of transmission and processing of data .The compression of video signals is required since it reduces resources required to store and transmit data. Video signals differ from image signals in several important characteristics. The most important difference is that video signals have a camera frame rate of anywhere from 15 to 60 frames/s, which provides the illusion of smooth motion in the displayed signal. Another difference between images and video is the ability to exploit temporal redundancy as well as spatial redundancy in designing compression methods for video .There are two important video and image compression standards JPEG and MPEG. JPEG is associated with still digital pictures while MPEG is associated with the digital video sequence.
