ABSTRACT:
A video decoder is provided wherein digitized samples of an input video signal are produced at a fixed sampling rate and, from such digitized samples, a fixed number of re-sampled digitized samples are produced for each detected sync pulse included in the video signal. The re-sampled digitized samples are stored in a buffer memory and are retrieved from such buffer memory at a rate synchronized to the sync pulse. With such an arrangement, the analog to digital converter operates at a fixed sampling rate, and overflow situations are avoided.
