<p>A video decoder is provided wherein digitized samples (C) of an input video signal (A) are produced (12) at a fixed sampling rate (B) and, from such digitized samples, a fixed number of re-sampled digitized samples are produced (24) for each detected sync pulse (D) included in the video signal (A). The re-sampled digitized samples (E) are stored in a buffer memory (32) and are retrieved from such buffer memory (32) at a rate (H) synchronized (16,20,22) to the sync pulse (D). With such an arrangement, the analog to digital converter (12) operates at a fixed sampling rate, and overflow situations are avoided. <IMAGE></p> |
