Abstract

A television receiver includes a chassis (12) having a digital tuner (14) 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 (18) 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 (34) including a RAM (130) (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 (100) 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 (32) having ten digit keys for generating binary signals representing the decimal digits between 0 and 9 and two characteristic keys to generate binary signals representing an increase and a decrease in the controllable characteristic is provided to enable user control of various operating modes of the receiver. When a user operates digit keys to form a number within a predetermined range of channel numbers e.g. 2-83, the control portion of the microcomputer causes the channel to be tuned. Subsequently operation of digit keys within the predetermined range of channel numbers causes the channel to be changed and operation of the characteristic keys causes the controllable characteristic to change. When a user operates digit keys to form a number not within the predetermined range of channel numbers, the control portion of the microcomputer causes power to be decoupled from the chassis. Subsequently, in response to the operation of a predetermined one of the characteristic keys, the control portion causes binary signals generated in response to the operation of the digit keys to be selectively coupled to either the RAM location associated with the present time or to the RAM location for future selections.
