<p>The present invention proposes a method for generating a digital video signal from an analog input video signal, which prevents picture jitter in the digitized video signal when the analog input video signal is not in complete conformity with a standard.
According to the invention, the method includes the steps of:
- detecting (1) the type of signal source;
- in case the type of signal source is a non-standard type, detecting (2) the existence of an error state;
- converting (3) the analog input video signal to a digital video signal;
- in case an error state exists, replacing (4) an error prone part of the digitized video signal with a substitute signal part; and
- in case the type of signal source is a standard type or no error state exists, keeping the digitized video signal unchanged.</p> |
