Abstract:
In one example, a digital video resampler and decoder is disclosed. An input buffer is coupled to a source of a video signal oversampled by at least two times. A horizontal synchronization detector is coupled to the input buffer, and detects horizontal synchronization boundaries. A counter is coupled to the horizontal synchronization detector to count a number of samples between horizontal synchronization boundaries. A comparator is coupled to the counter and compares the counted number of samples to a reference count. A sample corrector is coupled to the input buffer and modifies a block of samples based on a result from the comparator. An output buffer is coupled to the sample corrector to hold the modified block of samples. A comb filter is coupled to the output buffer, and generates first and second three-dimensional color values based on the modified block of samples.
