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.
