<p>A method of cancelling an abnormal synchronous signal including the steps of: detecting a predetermined pattern data synchronous signal from input digital data; and deciding that a detected synchronous signal is an actual synchronous signal if the detected synchronous signal has periodicity, and otherwise, annulling the detected synchronous signal. In the above-described method, only a normally-recorded actual synchronous signal is detected while cancelling abnormal synchronous signals from the detected synchronous signals using the periodicity of a synchronous signal and identification information. Thus, normal signal processing can be performed using the detected actual synchronous signal. <IMAGE></p> |
