Abstract
A program selection system for a consumer digital television receiver includes a numeric keypad and scrolling keys for selecting a channel through which a multi-program bit-stream is received. The numeric keypad and the scrolling keys may also be used to select an individual program from the multi-program bit-stream. In one embodiment of the invention, the numeric keypad is used first to select a channel and then to select a program within the channel. According to another embodiment of the invention, the numeric keypad is used to select the channel and another key is used to step through the programs that are contained in the multi-program stream that is carried by the channel. In a third embodiment, scrolling keys are used to select the next channel or the next program within the channel depending on whether the currently selected program is the last program in the bit-stream that is carried by the channel.
