A system and method for providing interactive multimedia services to subscriber premises utilizing wireless distribution within the subscriber premise. The service is provided via a communications link delivering to the subscriber premises broad band digital information including video and audio from a plurality of information providers and control signals in a multiplexed form. This multiplexed signal is then separated and processed on premise and distributed in a two-way fashion using frequency hopping code division multiple access (CDMA) spread spectrum using radio frequency signals preferably at UHF. Upstream control signals from the user installation are communicated from the individual user terminals in the same wireless manner.

Wireless video distribution

A digital network delivers multiplexed channels to a customer premises. Each multiplexed channel contains a digitally multiplexed data stream including digitized broadband information relating to a number of programs. At the customer premise, a shared processing system includes several channel selectors and program selectors. Each channel selector selects one of the multiplexed channels, and each program selector selects digitized broadband information relating to a selected program from a selected channel. A multiplexer combines the selected digitized broadband information from the program selectors into a transport stream. A transmitter system, for example comprising a digital modulator, a spread spectrum modulator and a broadcast antenna, provides a wireless broadcast of the digital transport stream throughout the customer premise and possibly one or more near by premises. Terminal devices within range of the broadcast receive the wireless broadcast and process selected digitized broadband information from the transport stream to present information relating to a selected program, e.g. on an associated television set.

Wireless on-premises video distribution using digital multiplexing

A system and method for providing interactive multimedia services to subscriber premises utilizing wireless and power line distribution within the subscriber premise. The service is provided via a communications link delivering to the subscriber premises broad band digital information including video and audio from a plurality of information providers and control signals in a multiplexed form. This multiplexed signal is then separated and processed on premise and distributed in a two-way fashion using frequency hopping code division multiple access (CDMA) spread spectrum using radio frequency signals preferably at UHF for the broadband downstream signal and power line carrier for the control signaling.

Customer premise wireless distribution of broad band signals and two-way

A system and method for providing interactive multimedia services to subscriber premises utilizing in whole or in part the public switched telephone network. The service is provided using an existing twisted wire pair subscriber line with Asymmetrical Digital Subscriber Line (ADSL) technology. The ADSL connection provides a 1.5 mbits/s downstream video information channel, a two-way telephone connection, and a 16 kbits/s control channel. This multiplexed signal is then separated and processed on premise and distributed in a two-way fashion as a complex radio frequency signal. Multiple television sets and telephone stations may be simultaneously served and may conversely communicate commands upstream to the multimedia network. A complete installation may be made in an entire premise without the necessity for any significant installation of new wiring. The system and methodology provide flexibility and are adapted to serve as an integral termination for multiple multimedia distribution and delivery architectures.
