METHOD FOR PROVIDING SELF-SURVIVING CLOCK TO BE SYNCHRONIZED WITH A TIMECAST IN COMMERCIAL BROADCASTING |
摘要 |
The present invention relates to a method of providing an independently surviving clock synchronized with a time signal service for commercial broadcasting, which allows an independently surviving clock provision module produced in the form of a small part to reset a divider (33) for dividing an oscillation frequency by a precise hourly time signal, which is detected in a broadcasting signal from the moment that external power is supplied, and for generating a second pulse, and to output both a second pulse, obtained by synchronizing the current time counted by a counter (34) with the precise hourly time signal detected in the broadcasting signal, and serial data about the current time to the outside of the module, thus providing a second pulse and time information having high precision to the general public at low cost. |
