DIGITAL TELEVISION SYSTEM WHICH SWITCHES CHANNELS IN RESPONSE TO CONTROL DATA IN A TELEVISION SIGNAL

摘要

A digital television system receives control data from a source and uses the control data to switch channels on a digital television. The digital television system includes a memory which stores computer executable process steps and channel switching circuitry which is capable of receiving television signals transmitted over a plurality of different channels. At least one of the television signals is received over a first channel and includes control data relating to a second channel. A controller is also included in the digital television system, which receives the control data and which executes the process steps stored in the memory so as to control the channel switching circuitry in accordance with the control data to switch from the first channel to the second channel.
