Control of audio/video equipment is provided by an apparatus constructed
like a computer, with audio and video subsystems. The audio subsystem
includes a programmable analog mixer and several analog and digital
multiplexers to route and mix multiple inputs to multiple outputs.
Databases are stored in computer mass storage to record preferences for
playback of digital versatile discs, compact discs and audio files stored
in the mass storage device, such as MP3 files. The playback preferences
may include video output format, language, surround sound mode, etc. for
DVDs and surround sound effects for CDs and audio files.
