摘要： A system, apparatus and method are disclosed for separating a current frame of a composite video signal into a luminance signal and a chroma signal. A relative chroma correlation value is generated using a plurality of lines of the current frame. A weighted sum of inter-line pixel differences of the current frame is generated using the relative chroma correlation value. A frame difference signal is generated by subtracting a previous frame of the composite video signal from the current frame. A detected motion signal is generated that corresponds to motion detected in the current frame. The weighted sum of inter-line pixel differences, the frame difference signal, and the detected motion signal are combined to generate the chroma signal. The chroma signal is subtracted from the current frame to generate the luminance signal.

摘要： The invention provides techniques for separating luma and chroma signal components in a composite SECAM video signal. During reception, the SECAM video signal is split into luma and chroma output. The amplitude of the chroma carrier is monitored during reception. If the chroma carrier amplitude is greater than a threshold, the value of the chroma output can be reduced. Also, if the chroma carrier amplitude is greater than another threshold, a portion of the chroma carrier can be added to the luma; or the trap band of the band-trap filter for extracting luma from the composite video can be reduced. The respective amount of the reduction in the chroma output and the increase in the luma output are independently determined but both may proportional to the magnitude of the deviation in the chroma carrier amplitude from the different thresholds.

Various aspects may generate a restored sampled signal by adding samples to the cropped sampled signal read from memory. Various aspects may, based on the synchronization signal, output the restored sampled signal coarsely synchronized to the received sampled signal. Various aspects may determine a phase difference between the output restored sampled signal and the output received sub-carrier. Various aspects may adjust the phase of the restored sampled signal in response to the determined phase difference.
