Apparatus, method and database for control of audio/video equipment
View Patent ↗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.
