Abstract

A home entertainment and information system is provided which assigns and transmits audio programming to audio output devices. Digital and analog signals from a variety of program sources are received by the home entertainment and information system. The system assigns and transmits to an audio output device a program that is distinct from programs assigned and transmitted to other audio output devices within the same system, and thus where two users are viewing different programs visually displayed on the same or different monitors, they hear the audio portion of the respective program they are viewing through individual audio output devices. An audio output device is also assignable to a remote control device such that when a program is selected using the remote control device, the audio portion of the program is transmitted to the assigned audio output device.
