Definition:Following MPEG-1, MPEG-2 video and audio compression standards were developed to meet the need in entertainment TV for transmission media such as satellite, CATV and digital storage media such as DVD.
The main effort was to compress CCIR-601 4:2:0 interlaced video with high quality since virtually all TV materials archived for last 50 years have been interlaced signals. Since the resolution is approximately 4 times that of CIF, the bit rate chosen for optimizing MPEG-2 was 4 Mbps [1, 2]. For the first time, functionality tools other than compression tools were specified in MPEG-2 — Scalability tools. MPEG-2 standards’ scope was enlarged to cover HD applications in July 1992. Now MPEG-2 handles a range of 4–15 Mbps as a generic coder. By generic, it is meant that the coding is not targeted for a specific application, but that the standard includes many algorithms/tools that can be used for a variety of applications under different operating conditions.
