发明名称 TELEVISION SIGNAL ENCODING APPARATUS
摘要 2094723 9208318 PCTABS00013 In a widescreen television signal processing system, side panel video information (IS; YSH/QS) is scrambled (749; 753) prior to modulating (751; 762) an auxiliary subcarrier which is ultimately combined (770) with main panel video information. In a preferred embodiment the scrambling process involves rotation of image line information about a pseudorandomly chosen cut-point. In a widescreen television signal receiver, corresponding unscrambling processes are utilized.
