TELEVISION SIGNAL ENCODED WITH AUXILIARY VERTICAL-TEMPORAL INFORMATION |
摘要 |
A system for encoding a progressive scan widescreen EDTV signal so as to be compatible with a standard NTSC receiver develops an auxiliary signal containing vertical-temporal information derived from image field difference information of the progressive scan signal. The auxiliary signal facilitates the conversion of the encoded NTSC compatible signal to progressive scan format in a widescreen progressive scan receiver. |
