A digital video disk (DVD) player is a device for playing video DVDs. A digital video disk player can perform an interactive playback in which a user can communicate with the player during playback. The information on a DVD formatted disc is recorded as discrete packets of data, in accordance with the applicable video and audio data compression standards. DVD provides means to record video and audio data at high density. In this case, the video data is recorded in the MPEG (moving picture expert group) while the audio data is recorded in the linear PCM format, dolby AC-3 format, MPEG format, etc. DVD subpictures are used as the graphical user interface (GUI) for such features as providing the user the ability to select from one of several different videos on a disc. DVD Video players are designed to reproduce both video and audio data recorded in a DVD-Video. A video disc player reading a DVD formatted disc may be controlled to display certain packets of data and skip over others. DVD players are each equipped with a pick-up head (PUH) and a pick-up base (PUB), the PUB is comprised of a spindle motor and a feeding system. DVD players may be coupled to other devices, such as a display device, a video/audio recording device, audio equipment and communicate with these other devices via a data bus. DVD players mix the decoded subpicture information with the decoded video into a single analog video signal for transport to a television.
