DEFINITION

Classification: 340/825

SELECTIVE:

(under the class definition) Subject matter for controlling one or more devices to obtain a plurality of results by transmission of a designated one of plural distinctive control signals over a smaller number of communication lines or channels than the total number of possible distinct results.

(1) Note. As used hereinafter, the term transmitter refers to the source of signals, and the term receiver refers to circuitry responsive to such signals.

(2) Note. This subject matter differs from simple switching in providing more than one result per channel in accordance with the signal content, as, for example, addressing one of a plurality of devices over a single channel.

(3) Note. Systems containing receivers, receivers and receiver subsystems, are classified in this and indented subclasses. Transmitter, per se, are classified in this class, subclass 345.

(4) Note. Transmission of signals providing for messages of arbitrary content is not classified herein.

(5) Note. Combinations with a specific art end element are usually classified therewith.
