ABSTRACT:
A simple, efficient technique for encoding NTSC video signals features sampling the signal at 8/3 the subcarrier frequency, generating no more than 256K samples for a full 525 line frame, generating as many samples per horizontal scan line as there are columns in a memory where the frame is to be stored, incrementing a row address counter for the memory once for each new horizontal scan line, and providing an analog reproduction of the color burst signal directly from and based solely on the digital samples of the color burst signal.
