Frequency generation during switch-over for multi-frequency video monitor |
摘要 |
The present invention discloses a method and apparatus for generating a synchronizing signal during a frequency switch-over of an input signal from a first frequency to a second frequency in a video monitor system. The method comprises the steps of: (1) detecting the frequency switch-over; (2) maintaining the synchronizing signal at the first frequency; (3) generating the synchronizing signal at a third frequency; (4) determining if the second frequency is valid; and (5) if the second frequency is valid, generating the synchronizing signal at the second frequency.
