Abstract: A video camera is provided with both a liquid crystal display as well as a smaller conventional eyepiece type viewfinder. Switching means responsive to an opening movement of the liquid crystal display from a closed position is used to automatically and smoothly switch off the viewfinder, switch on the liquid crystal display and to enable a speaker. The liquid crystal display is also used as a cover for relatively infrequently used setting switches and controls.

Abstract: Circuits for use with a receiver which notify the operator of a receiving station by means of an audio tone when an opposite station is calling or has ceased transmission. The transition of an opposite station from its transmitting to receiving state or vice versa is detected and a specific change-over sound based upon the detector output is introduced into the principal station's receiver audio amplifier circuits.

Abstract: A processing circuit for a composite color television signal formed of a chrominance component and a luminance component includes a comb filter of the type including a 1H delay line. In order to process the chrominance component, the comb filter is followed by an operational circuit providing a difference signal representing vertical correlation of the input chrominance component for consecutive line intervals, and a feedback loop circuit for combining the input chrominance component with the feedback difference signal before application to the comb filter. A detecting circuit detects correlation of video information in the luminance component in vertically aligned portions of successive horizontal line intervals, and provides a detecting signal which is used to adjust the feedback loop gain on the feedback loop circuit in accordance with the detecting signal. The processing circuit can further comprise a luminance comb filter including the delay line and an additive combining circuit, which is followed by a subtractive combining circuit and a band pass filter having an input connected to an output of the subtractive combining circuit and an output connected to an input of the latter. This circuit gives the luminance comb filter a flat frequency transfer characteristic. In the detecting circuit, a delay circuit is provided formed of a pre-emphasis circuit, an AM modulator, a delay line, an AGC circuit, an AM detecter, a de-emphasis circuit, and a low pass filter.

Abstract: A SIGNAL TRAP DEVICE AND METHOD FOR TRAPPING A DESIRED FM SIGNAL OUT OF A FREQUENCY MULTIPLEXED SIGNAL WHERE A PLURALITY OF FM SIGNALS ARE INCLUDED IN A FREQUENCY MULTIPLEXED FORM. A REPLAY SIGNAL REPRODUCED FROM A VIDEO CASSETTE TAPE IS SUPPLIED DIRECTLY TO A SUBTRACTER (21) WHILE BEING FED TO A FIXED DELAY CIRCUIT (22) AND A VARIABLE DELAYS CIRCUIT TO BE DELAYED THEREIN BY A PREDETERMINED DELAY TIME. THE DELAYED SIGNAL IS SUPPLIED ALSO TO THE SUBTRACTER (21), WHICH THEN SUBTRACTS THE DELAYED SIGNAL FROM THE REPRODUCED REPLAY SIGNAL AND OUTPUTS THE RESULT OF SUCH SUBTRACTION THEREFROM. THE DELAY TIME OF THE FIXED DELAY CIRCUIT IS SO SET AS TO CORRESPOND TO THE CENTER FREQUENCY OF THE CARRIER OF THE DESIRED FM SIGNAL TO BE TRAPPED. MEANWHILE THE DELAY TIME OF THE VARIABLE DELAY CIRCUIT IS SO SET AS TO CORRESPOND TO THE SIGNAL OBTAINED BY DEMODULATING THE DESIRED FM SIGNAL. THUS, THE DESIRED FM SIGNAL CAN BE TRAPPED PROPERLY WITHOUT ANY HARMFUL INFLUENCE ON THE OTHER FM SIGNAL.FIGURE 7
