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. The headend server also maintains a plurality of Internet browser applications active at all times to insure that a terminal requesting Internet access can be immediately interfaced to the ISP through one of the active browser applications. Each of the downstream television signals includes a vertical synchronization signal that is preferably employed to generate a framing signal for synchronizing upstream transmission of the data packets comprising the information requests from the terminals.
