ABSTRACT:
An all-channel two mode television tuning system includes a counter for sequentially generating channel numbers to adjust tuning. An 82 .times. 1 bit read/write memory is addressed in a program mode by the generated channel numbers to provide locations for storage of signals for tuning to preselected channels. In the operate mode channel numbers are again generated to access the memory locations and logic circuitry determines if generated channel numbers correspond to preselected channel numbers. Channel skip control circuitry is activated in the operate mode to cause very rapid counting faster than viewer perception whenever non-selected channel numbers are determined and a much slower speed or pause condition when correspondence with a preselected channel number is determined.
