Abstract
A method of separating a chroma data component from a video data stream includes determining a phase relationship between a color burst in digital video data samples of a composite video signal and a local clock signal which processes the digital video data samples. In response to determining the phase relationship, interpolation filtering is performed on the digital video data samples corresponding to first and second display lines to generate phase aligned video data samples. Adaptive filtering is then performed utilizing the phase aligned video data samples corresponding to the first and second display lines to separate the chroma component from the digital video data samples corresponding to the first display line.
