DVD-Video is a popular video format that uses DVDs to store digital video. This format was widely used in the 2000s and dominated the home video market in most parts of the world until it was replaced by Blu-ray Disc. DVD-Video requires an MPEG-2 decoder and a DVD drive to play, both of which are available in DVD players and computer DVD drives with software DVD players. Most commercial DVD movies are encoded with MPEG-2 compressed video and audio in various multi-channel formats with a data rate between 3 and 9.5 Mbps. DVDs use an adaptive bit rate, which means it changes as needed to maintain a consistent video quality.
When it comes to video display, DVD-Video is designed to be compatible with both standard and widescreen formats. Videos recorded in 4:3 aspect ratio are displayed normally on a standard 4:3 screen. On a 16:9 widescreen system, the video is either enlarged or it has black bars added to the sides. Before transferring 4:3 video to DVD, it may have been reformatted in various ways, such as letterboxing or panning to create a wider image. However, the DVD player treats the signal as standard and plays it back accordingly.
