Video compression is essential for multimedia communication. Without using video compression, it is impossible to provide fast video transmission over the wire and wireless transmission medium. Widely used video coding standard is the Moving Picture Expert Group (MPEG) which is used in digital video applications such as Digital Video Disc (DVD) and High Definition Television (HDTV). This review paper discusses the basics of video compression i.e. its need, feasibility and the quality measurement of video frames. Moreover it also explains the various video compression techniques such as MPEG 1, MPEG 2 and MPEG 4. Finally theoretic comparison of these algorithms is done and their limitations are discussed in brief.
