Abstract

An information distribution system enhances a vehicle audio/video system. The system flexibly delivers audio and video, potentially obtained from many different sources, to different locations in the vehicle. Each passenger receives the audio or video that is of interest to them without distracting interruptions.

wherein the first plurality of gain logics is operable to scale a first data sequence of a first input data stream included in the plurality of input data streams with a first gain value for output on the first output channel, and simultaneously, the second plurality of gain logics is operable to scale the first data sequence of the first input data stream with a second gain value for output on the second output channel;

wherein the first plurality of gain logics and the second plurality of gain logics are operable to scale the data sequences destined for the same output channel independently of each other;

wherein each of the plurality of signal combiners combines scaled data sequences destined for the same output channel into a single combined output data stream; and

wherein the router is further operable to completely block delivery of a specific input data stream with respect to all output channels based on at least one of a time, a date, and a user preference.

2. The system of claim 1, where the plurality of input data streams comprise a plurality of input audio data streams, the plurality of output channels comprise a plurality of audio output channels, and the scaling configurations comprise a volume weighting for the data sequences destined for the plurality of audio output channels.
