Method for storing digital channel tuning data, and circuit, television

Abstract

The disclosure relates to a method and a circuit for storage of digital tuning data and parameters for a number of television channels in a rewritable memory. The channel search is initialized by pressing a single button to initialize a scan of the reception frequency band. The scanning of the frequency range is interrupted for a preset time-out period .DELTA.t each time a stop-scan signal is generated and resumes automatically until the entire range has been scanned. After each stop-scan pulse, if the single button is pressed during a time-out period, At, the system begins toggling through the possible values of each parameter relating to the station, the current value of the parameter being memorized when the single button is pressed again. The invention also includes a television and video cassette recorder implementing the above method.
