ABSTRACT:
A process in displaying a video signal according to a sequence of synchronous pulses is disclosed. The process is based on the adjustment of timing of the active part of a video signal to be displayed. That is the starting point of active part of the video signal for each line-displaying is properly and immediately adjusted according to the detection if the trailing end of the previous active part of the video signal lags the synchronization pulse next to its leading end, whereby it can be achieved that the video signal is always displayed in a specified region and synchronization failure can be avoided.
