Auxiliary interface apparatus
First Claim
1. An auxiliary interface device, comprising:
- an electronic circuit to interface to the signal output of a signal source, said signal source developing or receiving more than one signal, and providing for the user selection of at least one of the signals in deference to the others so that said apparatus provides for the selection of at least one special signal having predetermined characteristics,a detector which recognizes the presence of the at least one said special signal when present or part of a signal developed by the apparatus to which said auxiliary interface device is connected, said detector being able to distinguish between said at least one special signal and other signals ordinarily present or developed by the apparatus to which said auxiliary interface device is interfaced,a signal switch to substitute at least one auxiliary signal in place of a signal output by the apparatus to which said auxiliary interface is interfaced,said signal switch being configured to substitute said at least one auxiliary signal for the signal normally developed by said apparatus to which said auxiliary interface device is interfaced when said detector recognizes the presence of the at least one special signal in the signal normally developed by said apparatus to which said auxiliary interface device is interfaced.

Abstract
An auxiliary interface device, comprising an electronic circuit to interface to the signal output of a signal source, said signal source developing or receiving more than one signal, and providing for the user selection of at least one of the signals in deference to the others so that said apparatus provides for the selection of at least one special signal having predetermined characteristics, a detector which recognizes the presence of the at least one said special signal when present or part of a signal developed by the apparatus to which said auxiliary interface device is connected, said detector being able to distinguish between said at least one special signal and other signals ordinarily present or developed by the apparatus to which said auxiliary interface device is interfaced, a signal switch to substitute at least one auxiliary signal in place of a signal output by the apparatus to which said auxiliary interface is interfaced, said signal switch being configured to substitute said at least one auxiliary signal for the signal normally developed by said apparatus to which said auxiliary interface device is interfaced when said detector recognizes the presence of the at least one special signal in the signal normally developed by said apparatus to which said auxiliary interface device is interfaced.

12. The Interface device comprising:
-
electronic circuitry to interface to a signal output of a signal source apparatus, said signal source apparatus generating or receiving of a plurality of signals and permitting for the user selection of one of those signals, such that said apparatus allows for selection of a plurality of special signals, at least one detector to recognize and distinguish between each of said plurality of special signals to which said auxiliary interface device is interfaced, a plurality of switches operated in accordance with said at least one detector configured to substitute at least one auxiliary signal from among a plurality of auxiliary signals according to the presence of the special signal, and corresponding to said at least one special signal in place of a signal normally developed by or present in the apparatus to which said auxiliary interface is interfaced, said plurality of switches being operated so as to substitute one or more of said plurality of auxiliary signals when said detector recognizes the presence of one or more of said corresponding special signals. - View Dependent Claims (13, 14, 15, 16)
