Abstract: Separation of luma and chroma in a video. In an embodiment, values on a current line of the sampled video signal, at ¼-period intervals, are compared with values on a previous line of the sampled video signal, at ¼-period intervals. Values on the current line of the sampled video signal are compared to values on a subsequent line of the sampled video signal. This gives information about the vertical frequency content. Values on the current line are compared with values having the same chroma phase on the same line to provide information about horizontal frequency content. The data of vertical and horizontal frequency logic are used by the decision logic to determine the appropriateness of combing based on these comparisons. If combing is not appropriate, the signal is bandpass filtered instead of combed. The low-pass and combing filters are applied to the original signal, not an interpolated or resampled signal.
