Title: Dynamic channel assignment for data transmitted via cable television channels
Inventor: MAJETI VENKATA CHALAPATHI
IPC: H04N7/167
Filed: 1996-04-02
Abstract: A system which avoids the bandwidth inefficiencies of simply providing multiple separate and independent channels for distributing data services over television compatible networks by considering the multiple channels as one unit and managing them as one unit with an upstream bandwidth management unit. This bandwidth management unit dynamically assigns active users to unused bandwidth among multiple channels. To accomplish this, the bandwidth management unit records each request for channel bandwidth that is made, each request that is being actively fulfilled, and each request that has been completed. Thus, data serviceproviders, such as multimedia services, can efficiently use multiple 6 megahertztelevision network compatible channels to distribute their data to many requesters/users at high rates of speed over a relatively inexpensive existing network.

Title: Secure radio personal communications system and method
Inventor: DENT PAUL WILKINSON
IPC: H04B15/00
Filed: 1995-02-15
Abstract: A secure radio personal communication system and method includes a base station which relays cellular verification signals between a wide area cellular network and a cellular terminal via the wire telephone network. Thus, cellular telephone calls which are routed to a cellular terminal via a base station, when the cellular terminal is within a local region covered by the base station, may be exchanged between the cellular network and cellular terminal over the wire telephone network. Calls from the wide area cellular network which are routed through the base station can thus employ the same authorisation systems and methods which are employed by the wide area cellular network. Signals between the base station and the cellular terminal are preferably exchanged when the cellular terminal is parked in the base station. Verification and encryption signals may be exchanged. The same signals may be used for enhanced security when the base station is relaying wire network calls to the cellular terminal when the cellular terminal is in the local region. Alternatively, separate verification and encryption protocols may be used.
