A DVD player is a device that plays discs produced under both the DVD Video and DVD Audio technical standards, two different and incompatible standards.
Technical Details
A DVD player has to complete these tasks:
* Read a DVD disc in ISO – UDF version 1.2 format
* optionally decrypt the data with either CSS and/or Macrovision
* read and obey the DVD's Regional lockout codes and display a warning if the player is not authorised to play the DVD
* decode the MPEG-2 video stream with a maximum of 10 Mbit/s (peak) or 8 Mbit/s (continuous)
* decode sound in MP2, PCM or AC-3 format and output (with optional AC-3 to stereo downsampling) on stereo connector, optical or electric digital connector
* output a video signal, either an analog one (in NTSC, PAL or SECAM format) on the composite, S-Video, SCART, or component video connectors, or a digital one on the DVI or HDMI connectors
