Abstract
A television receiver cable of tuning either 'air' channels in an 'air' tuning mode or 'cable' channels in a 'cable' tuning mode includes apparatus for automatically selecting the tuning mode. The auto-tuning mode apparatus operates in conjunction with apparatus for automatically programming a memory for storing tuning information for tunable channels. When the auto-programming mode is selected, the receiver is caused to operate in the cable tuning mode and a search is conducted for active cable channels. If a predetermined number of active cable channels is located, the receiver remains in the cable tuning mode and the memory is programmed with tuning information for all of the cable channels. If the predetermined number of cable channels is not located, the receiver is caused to operate in the air tuning mode and the memory is programmed with tuning information for all of the air channels.
