A split channel bridging unit includes a router that operates under the control of a control processor to route packets of information destined for a user to a modulator which is connected to the cable distribution head-end of the cable television system which serves the requesting user. The modulator encodes the digital information transmitted from the router and encodes it in an RF channel to be carded by the television cable. The cable distribution head-end combines this channel with other conventional cable television sources to broadcast these channels to its users. The customer premises equipment of the user includes an RF demodulator and packet receiver which demodulates the RF encoded signals and utilizes the packet receiver to transmit the digital information addressed to the particular user to the user's personal computer. Upstream requests are made by the user by utilizing a modem connection over the public switched telephone network with a terminating modem contained in the split channel bridging unit. Secured low-speed control information is preferably supported bidirectionally by utilizing a modem connection over the public switched telephone network.
In a telecommunication network that supports communications between users and information service providers by using high-speed cable transmission channels to transport information to the users' customer premise equipment and lower speed transmission channels that carry users' requests from the users' customer premises equipment, the lower speed transmission channels transported by a transmission medium physically separate from the transmission medium that transports the high speed cable transmission channels, a split channel bridging apparatus comprising:
A telecommunication system that supports communications between users and information providers by using cable transmission channels to transport information to the users' customer premise equipment and other transmission channels to carry users' requests from the users' customer premises equipment, the other transmission channels being transported by a transmission medium physically separate from the transmission medium that transports the cable transmission channels, the system comprising:
A telecommunication method for communications between users and information providers by using cable transmission channels to transport information to the users' customer premise equipment and other transmission channels to carry users' requests from the users' customer premises equipment, the other transmission channels being transported by a transmission medium physically separate from the transmission medium that transports the cable transmission channels, the method comprising:
In a telecommunication network that supports communications between users and information service providers by selectively using high-speed cable transmission channels and low-speed transmission channels to transport information to the users' customer premises equipment, the low-speed transmission channels also utilized to carry users' requests from the users' customer premises equipment, the low speed transmission channels supported by transmission medium physically separate from the transmission medium that supports the high-speed cable transmission channels, a split channel bridging apparatus comprising:
