<p>A video signal is coded by transmitting only selected samples, the samples to be transmitted being selected by determining whether omission of that sample and transmission of the next sample would cause any regenerated samples to differ from the corresponding actual input sample by more than a threshold value. If not, that sample is omitted. The values actually transmitted may define the ends of ''best-fit'' straight lines. The threshold may be adaptively dependent upon picture content. A reduction in transmission bandwidth can be obtained.</p> |
