Abstract
A television receiver includes a chassis having a digital tuner for generating local oscillator signals for tuning the receiver to respective channels in response to binary signals representing corresponding channel numbers and a signal processing unit for controlling at least one characteristic of the receiver such as the sound level, in response to binary signals representing the controllable characteristic. The receiver also includes a microcomputer including a RAM (Random Access Memory) with at least one memory location for storing binary signals representing the present time and a plurality of memory locations for storing binary signals representing future times and channel numbers of channels to be tuned at those times. A control portion of the microcomputer causes binary signals representing the channel number associated with a future time to be coupled to the digital tuner when the present time matches the future time. A keyboard having ten digit keys for generating binary signals representing the decimal digits between 0 and 9 and two characteristic keys to generate binary signal representing an increase and a decrease in the controllable characteristic is provided to enab…
