  • Shared use video processing systems for distributing program signals from multiplexed digitized information signals
    Patent number: 5784683
    Abstract: A broadcast system supplies multiplexed channels to a plurality of receiving systems. The broadcast system preferably comprises a wireless digital simulcasting network. Each multiplexed channel carries multiplexed digital information signals relating to a group of programs. At least one of the receiving systems serves a plurality of living units. The multi-unit receiving system includes common equipment to perform as much of the processing of the digital information signals as is practical for the particular installation. The common equipment includes a digital receiver processing each multiplexed channel to capture a digital transport stream therefrom and a demultiplexer for separating out the digital information signals for each program from each digital transport stream. A switch routes selected information signals to individual drops or loops going to the living units.
