Software clock operating method for electronic entertainment appts. e.g with TV receiver or video recorder

The method of operating a software clock involves using a clock generator (1) which provides high-frequency signals at e.g. 16 MHz for a frequency divider (2) and a counter/threshold comparator (3). When a predetermined number of clock pulses has passed, the counter is reset and a time increment sig...

Zusammenfassung:	The method of operating a software clock involves using a clock generator (1) which provides high-frequency signals at e.g. 16 MHz for a frequency divider (2) and a counter/threshold comparator (3). When a predetermined number of clock pulses has passed, the counter is reset and a time increment signal is supplied to a register (4) contg. values corresp. to hours, minutes and seconds.A videotex signal processor (5) extracts real-time information for a comparator/corrector (6). If the times do not correspond, the register is reset (I1) and a correction dependent on the discrepancy is entered (12) into a memory (7) for application to the threshold comparator.
