Abstract:
A synchronizing signal detecting apparatus comprising:a timer for outputting time instant data;detecting means for detecting a time instant value for each of a plurality of potential synchronizing signals occurring during a time frame series;means for determining a count value for time instant values which are detected for consecutive time frames;first storage means for storing a detected time instant value for each of the plurality of potential synchronizing signals;second storage means for storing each time instant value having a count value equal to a preselected amount;time data coincident detecting means in which only one time instant value having the largest count value is detected from time instant values stored in said second storage means, and when one such time instant value cannot be detected, the detecting operation performed by said detecting means is sequentially repeated for subsequent time frames series; andmeans for outputting a synchronizing signal when said time data coincident detecting means detects one time instant value having the largest count value.
