ABSTRACT:
In a widescreen television signal processing system, a side panel high frequency luminance information component and a side panel color difference information component are combined and processed as a combined signal by a noise reduction encoder, time expander and filter before modulating an auxiliary subcarrier. After demodulation at the decoder, the combined signal is filtered, time compressed and processed by a noise reduction unit before being separated into its constituent components.
