摘要:
A method for the transmission of a video signal, in which the analogue signal is converted into a digital signal and is digitally transmitted. However, before the transmission is transformed into the spectral domain, some portions of the digital signals are variously weighted on the basis of the physiological behavior of the eye. This weighting is performed by coding the signals to be transmitted in their representational accuracy.
