DVD-Video

DVD-Video is a video format used to store digital video on DVD discs, and is currently the dominant consumer video format in Asia, America, Europe, and Australia.

Discs using the DVD-Video specification require a DVD drive and a MPEG-2 decoder (e.g., a DVD player, or a computer DVD drive with a software DVD player). Commercial DVD movies are encoded using a combination of MPEG-2 compressed video and audio of varying formats. Typically, the data rate for DVD movies ranges from 3 Mbit/s to 9.5 Mbit/s, and the bit rate is usually adaptive. It was first available for retail around 1997.
