Video is the sequence of images played with respect to time. The successive images are highly correlated with each other. Video compression algorithms take the advantage of this fact. Only the residual informati on is transmitted using the technique called as block based motion estimation and motion compensation . MPEG1 (Motion Picture Expert Group), MPEG2, MPEG4, H.261, H.263, H.264 are the ancestors of H.265. Work on the emerging “Advanced Video Coding” (AV C) standard now known as ITU - T(International Telecommunication Union) Recommendation H.264 and as ISO 14496(International Organization For Standards) (MPEG - 4) Part 10 has dominated the video coding standardization community. The work has been stimulating, intense, dynamic, and all - consuming for those of us most deeply involved in its design. The time has arrived to see what has been accomplished. The new H.264/AVC & Enhanced version H.265 standard is designed to provide a technical solution, the H.265 is th e latest video compression technique in which 50% of bit rate is saved more than H.264 and broad range of applications, including broadcast over cable, satellite, cable modem, and terrestrial. It finds the applications in interactive or serial storage on o ptical and magnetic storage devices, DVDs (Digital Video Disk). Conventional services over Ethernet, LAN (Local Area Network), wireless and mobile network and mobile.
