<p>An error detecting circuit of a system time clock is described, which includes a counter section for counting the pulses of the system time clock and resetting the count value at every given period, an error generating section for generating an error value, a loop filter for outputting a voltage value in accordance with the error value, and a voltage controlled oscillator for providing a clock signal corresponding to the voltage value from the loop filter. The frequency of a system time clock of a decoder is modified in accordance with the difference of the system time clock of the decoder from that of an encoder, thereby synchronizing the system time clocks of the decoder and the encoder.</p> |
