Abstract: In a broadcast-program selection history information acquisition apparatus and its method, the totalization side can easily totalize selection history information. To acquire the selection history information of a broadcast program selected out of broadcast programs of a plurality of channels, the selection information of the broadcast program is stored at a predetermined acquisition timing and the selection history information which is composed of a plurality of pieces of selection information stored every plurality of acquisition timings is transmitted to a notification destination at a predetermined transmission timing.

Abstract: A television receiver apparatus has large versatility to adapt itself to newly offered services or new modes of use. An external memory element loaded with a flash memory is connected to the receiver apparatus through an external memory interface having a connector and an interface circuit. The external memory element stores information such as a program for implementing an additional function or data such as video and audio data. The information stored in the external memory element is taken up by the receiver apparatus through the external memory interface. The information from the external memory element is processed by a controlling portion of the receiver apparatus so as to be subjected to use.

Abstract: A continuous both-side playback type video disc apparatus having an external command signal generator for generating an external command signal to an external recorder in response to a playback start signal or a lead-in or lead-out track detection signal obtained from a signal reading head, and also an external command signal output terminal for supplying the external command signal therefrom. Synchronized operation control is executed in such a manner that, upon completion of playing back one side of a disc, the recording operation of the external recorder is temporarily brought to a halt by a pause signal at the instant of detection of the lead-out track by the signal reading head, and after proceeding to playback of the other side of the disc, the recording operation is resumed at the instant of detection of the lead-in track on the other side of the disc by the signal reading head.

Abstract: A PCM (pulse code modulated) audio signal recording and/or reproducing apparatus, operates with plural scanning periods, in which a rotary head scans obliquely the longitudinal direction of a tape, and which scanning periods are separated into a plurality of segment periods. PCM audio signals are recorded on one or more channels of a plurality of track channels, formed by the alignment of respective segment tracks which are scanned by the rotary head during the corresponding segment periods of each scanning period, and an identifying signal, indicative of the fact that the PCM audio signals is already recorded, is superimposed upon the PCM audio signal and recorded together therewith on the track channels, whereby it becomes possible to easily identify whether or not the PCM audio signal is recorded on the of track channels.

Abstract: A tape recording apparatus in the form of a modified VCR is employed to record broadcast signals received by an antenna while moving through a radio-broadcast reception area. The recorded signals are maintained in an undetected, modulated-carrier form so that played-back signals from the VCR can be coupled to a radio receiver in a fixed location for testing under mobile conditions. A commercially available VCR is modified to avoid modulating FM signals by frequency a second time.

Abstract: Drop-outs are detected and compensated for in an apparatus for reproducing video and audio signals that have been recorded as first and second mixed signals in adjacent first and second parallel tracks, respectively, on a magnetic record medium such as a tape and in which each of the mixed signals is comprised of a video signal mixed with at least one frequency modulated audio signal, in the case of monaural, having a respective carrier frequency. The recorded mixed signals are reproduced by two magnetic heads that scan the adjacent first and second tracks to reproduce alternately the mixed signals recorded thereon, and drop-outs are detected in the reproduced signals. The audio signals are separated from the reproduced mixed signals, frequency demodulated and combined to form a substantially continuous or reconstituted demodulated audio signal.

Abstract: A video and audio signal recording apparatus includes first and second frequency-modulators in which a first audio signal, for example, a stereophonic left signal, modulates a first carrier and a second carrier with a frequency higher than that of the first carrier so as to provide first and second FM audio signals, respectively, third and fourth frequency-modulators in which a second audio signal, for example, the stereophonic right signal, modulates a third carrier with a frequency higher than that of the second carrier and a fourth carrier with a frequency higher than that of the third carrier so as to provide third and fourth FM audio signals, respectively, a first mixing circuit for mixing the first and third FM audio signals with a video signal, such as, a composite color video signal having a frequency modulated luminance component signal in a frequency band separated from the band of a frequency-converted chrominance component signal so as to provide an interval therebetween for accommodating the firs
