Abstract:
1. A digital video resampler and decoder comprising: an input buffer coupled to a source of a video signal having horizontal synchronization boundaries, the video signal being oversampled by at least two times; a horizontal synchronization detector coupled to the input buffer, the horizontal synchronization detector to detect horizontal synchronization boundaries in the video signal; a counter coupled to the horizontal synchronization detector, the counter to count a total number of samples between a pair of the detected horizontal synchronization boundaries; a comparator coupled to the counter, the comparator to compare the counted number of samples to a reference count; a sample corrector coupled to the input buffer, wherein the sample corrector is operable to modify a block of samples based on a result from the comparator to generate a modified block of samples; an output buffer coupled to the sample corrector to hold the modified block of samples; and a comb filter coupled to the output buffer, the comb filter to generating a first and second three-dimensional color values (U.sub.3D & V.sub.3D) based on the modified block of samples.
