Abstract
A method of canceling an abnormal synchronous signal including the steps of: detecting a predetermined pattern data synchronous signal from input digital data; determining 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, normally-recorded actual synchronous signals are detected while abnormal synchronous signals are canceled from the detected synchronous signals, on the basis of the periodicity of the synchronous signals and identification information. Thus, normal signal processing can be performed using the detected actual synchronous signal.

- (a) detecting a predetermined pattern data synchronous signal from input digital data;
- (b) determining that a detected synchronous signal is an actual synchronous signal if the detected synchronous signal has periodicity;
- and
- (c) annulling the detected synchronous signal if the detected synchronous signal does not have periodicity.
A method of canceling an abnormal synchronous signal, comprising the steps of:
- (a) detecting a predetermined pattern data synchronous signal from input digital data;
- (b) determining whether a detected synchronous signal has periodicity;
- (c) when the detected synchronous signal has periodicity, determining that the detected synchronous signal is an actual synchronous signal if identification information is detected;
- and
- (d) annulling the detected synchronous signal if identification information is not detected.
A method of canceling an abnormal synchronous signal in a method of recording digital data in divided pre-synchronous blocks and data synchronous blocks and reproducing the recorded digital data, comprising the steps of:
- (a) detecting a predetermined pattern data synchronous signal from the recorded digital data;
- (b) determining that a detected synchronous signal is an actual synchronous signal if the detected synchronous signal has a first period;
- (c) determining that the detected synchronous signal is an actual synchronous signal if the detected synchronous signal is a data synchronous signal for a data synchronous block having a second period different from said first period;
- and
- (d) annulling the detected synchronous signal if the detected synchronous signal is not an actual synchronous signal as determined in the steps (b) and (c).
