MPEG-2

MPEG-2 is a group of coding standards for digital audio and video, agreed upon by Moving Pictures Experts Group(MPEG). MPEG-2 is typically used to encode audio and video for broadcast signals, including direct broadcast satellite and Cable TV. MPEG-2, with some modifications, is also the coding format used by standard commercial DVD movies. MPEG-2 includes a few parts: Systems part (part 1) defines Transport Stream to carry digital video and audio over somewhat-unreliable media, and are used in broadcast applications. The Video part (part 2) provides support for interlaced video. The MPEG-2 Audio part (Part 3) enhances MPEG-1's audio by allowing the coding of audio programs with more than two channels. In MPEG-2 AAC (Part 7), audio can alternatively be coded in a non-backwards-compatible way, which allows encoders to make better use of available bandwidth.
