Abstract: An access system and method for providing interactive access to an information source through a television distribution system is disclosed. The distribution system includes a television distribution network, headend distribution equipment at the headend of the distribution network, and a plurality of terminals at terminal ends of the distribution network. An input device and an upstream transmitter are associated with one of the terminals to input a command for the information source and to transmit the inputted command on an upstream channel of the distribution network, respectively. A headend server, upstream receiver, and data encoder are associated with the headend distribution equipment. The headend server is interfaced to the information source. The upstream receiver is interfaced to the headend server to receive and forward the command to the headend server.

Abstract: A system and method for accessing Internet-based and other information through a user television in a television distribution network enables a user to access and view information which is related to the programming content of a currently viewed television broadcast. This concept, known as channel hyperlinking, enables a television viewer to download Internet Web pages, and the like, which are related to a currently viewed advertisement, program, newscast, etc. To facilitate channel hyperlinking, each user of the system sends channel hyperlink requests through an upstream channel to a network headend by actuating a hyperlink button on a television remote control, for example. The network headend is interfaced to the Internet by means of an Internet Service Provider (ISP), and downloads HTML Web page data from the Internet to the requesting user.

Abstract: An access system and method provides interactive access to an information source, such as the Internet, through a networked distribution system, such as a television distribution system. Each user in the television distribution system can access the Internet through an associated terminal by sending commands through an upstream channel to a headend server which is interfaced between a television network headend and an Internet Service Provider(ISP). The headend server manages all Internet information requests from the terminals by forwarding the requests to the ISP and receiving the requested information therefrom. An Internet Protocol (IP) address is assigned only to the headend server which keeps track of the terminals requesting information by means of terminal identification numbers or codes associated with each request.
