A microprocessor control system is described for effecting channel tuning and function selection in a television receiver. The system will respond to commands entered by a set of controls at the television receiver or to remote control commands received at the television receiver. A channel number display is also provided whereby the channel number of a station currently tuned is displayed. A microprocessor within the system is programmed to validate control information received from an operator either by remotely generated commands or by controls located on the television receiver. Operator supplied information is processed and implemented by the microprocessor control system to effect control over the television receiver.
