HIGH-EFFICIENCY CODING FOR PAL COLOR TELEVISION SIGNAL
PAL彩色电视信号的高效编码

Proceeding from the specific characteristics of PAL television signals adopted in China, this paper points out that if the fs=2fsc of sub-Nyquist sampling and DPCM-encoding is used for PAL complete signal, and if the blanking time is utilized to transmit code of effective area, it is possible to transmit a color TV signal over PCM three-group channel.
