Abstract: If previously stored transmitters allocated to certain program settings in an entertainment electronics appliance are reallocated to the usual program settings, e.g., because of a changed transmitter distribution arrangement due to a change of location, time consuming reprogramming becomes necessary. The present invention concerns obtaining a simple sequencing process for reallocating previously stored channels to the desired program setting number. A microprocessor receives a command, and within a time window determined by the command, reads previously programmed data concerning two selected program settings from a main memory into a first auxiliary memory, and from this auxiliary memory into a second auxiliary memory, interchanging the channel numbers, and from the second auxiliary memory into the main memory again, so as to keep the same program numbers.

Abstract: The disclosed embodiment of the invention comprises method and/or equipment to program a video or audio appliance, such as a video recorder, with tuning data such as the channel number, frequency or the like, required to receive television and/or radio transmissions, whereby the tuning data specific to a station can be entered into a program memroy of the video or audio appliance and be assigned to a program number or other program identification indicia. The tuning data and its assignment to a program number or other program identification are loaded automatically from a program memory of an already programmed video or audio appliance, such as a television set. In addition, apparatus is included for automatically loading the current time, for example, from videotext decoder unit.

Abstract: A continuous time-of-day or date correction of a signal produced by a clock module is obtained from the data in a video-text or teletext signal that contains accurate time-of-day and/or date reference information. When the video-text/teletext data contain such reference information, the data of the output signal of the clock module are compared, on a continuous basis, with the received video-text/teletext. In case of a deviation between the clock module data and the reference information, a correction signal is applied to the clock module and corrects the clock module.
