ENCODER TO CONVERT TELEVISION SIGNAL, DECODER TO CONVERT TELEVISION SIGNAL, PERFECT COMMUNICATION PROCESS FOR TRANSMISSION OF TELEVISION SIGNALS AND APPLIANCE TO PROVIDE SIGNALS

摘要

In a Multiplexed Analog Component (MAC) color television transmission system in which the MAC signal is to be converted at the receiver to a composite color television signal having a 227.5 fH color subcarrier, frequency-generation equipment required at the receiver is simplified by selecting the various frequencies in accordance with the following relationship, (f0/n)=(3f1/2)=3f2=f4=227.5k fH, where: f0 is the master clock frequency, f1 is the luminance sampling frequency, f2 is the chrominance sampling frequency, f4 is the MAC sampling frequency, fH is the horizontal line frequency, and n and k are positive integers.
