DEFINITION

Classification: 386/109

Compressing in recording or decompressing in reproducing:

(under subclass 46) Subject matter wherein at least a parameter (bandwidth, data, time, etc.) of the television signal is reduced at the time of writing-in, or increased at the time of reading-out while preserving its information content.

27, for compressing or decompressing of a frequency modulated color television signal.

33, for compressing or decompressing of a color television signal.

101, for time compressing of an audio signal.
