BAND COMPRESSING TRANSMITION METHOD BY SUB-NYQUIST SAMPLING

摘要

The method is for transmitting video signal utilizing sub- nyquist sampling method to obtain broad band transmission characteristics. The circuit includes a first sampling unit (14) for sampling brightness signal using a first sampling pulse, a second sampling unit (22) for sampling color difference signal using a first sampling pulse, a first D/A converter (15) for converting sampled brightness signal to analog signal, a second and a third D/A converter (23,24) for converting sampled color difference signals, a Y/C divider (12) for dividing video signal into brightness signal and carrier color signal, a decoder (18) for decoding carrier color signal to generate color difference signals, and an encoder (27) for converting color difference signals to carrier signals.
