DEFINITION
Classification: 386/33
Compressing when recording or decompressing when reproducing:
(under subclass 1) Subject matter wherein a parameter (bandwidth, data, time etc.) of a component of the color television signal is reduced at the time of writing-in, or increased at the time of reading-out while preserving its information content.
