<p>Composite video is separated into chrominance and luminance using a separation filter selected on a pixel by pixel basis accordance with horizontal, vertical and temporal differences. Signal in a subcarrier domain passes through complementary chrominance and luminance filter paths, each path containing a rate converter and a synchroniser. In the chrominance filter path a chrominance/cross-colour separation filter operating on demodulated chrominance, separates cross-colour which passing through a modulator before combination with the ouptut of the luminance filter path, information from the demodulator being carried forward for use by the remodulator.</p> |
