Set top box provided with timing function

The utility model provides a set top box provided with a timing function comprising a high frequency head, a QAM demodulator, a TS flow de-multiplexing module, a main control module, a timing module, and a display module. The main control module can be used to transmit the standard time and the date information, which are received by the high frequency head, demodulated by the QAM demodulator, and de-multiplexed by the TS flow de-multiplexing module, to the timing module for the correction of the system time of the set top box, and then the display module can be driven to display the standard time and the date information. The loaded standard time information of the TV signals can be analyzed for the automatic timing, and the system time of the set top box can be updated and displayed.
