Pulse code modulation of video signals: subjective tests on acceptable limits for timing jitter in the decoded analogue samples

摘要

Tests have been performed to investigate the subjective effect, on a television display, of timing jitter in the samples of a 625-line video signal obtained from a p.cm. digital-to-analogue converter. The results of these tests have been used to obtain limits for the amount of both random and sinusoidal forms of jitter which can be tolerated in a broadcast-quality television system.
