DEFINITION

Classification: 348/571

IMAGE SIGNAL PROCESSING CIRCUITRY SPECIFIC TO TELEVISION:

(under the class definition) Subject matter including a specific circuitry peculiar to processing image information of a television signal.

SEE OR SEARCH THIS CLASS, SUBCLASS:

725, for demodulator, per se, and other receiver circuitry in which no processing, per se, of the image information occurs.
