摘要： A signal processing apparatus for changing the frequency characteristics of an input signal, e.g.--a video or audio signal, allows a signal to pass through a transmission circuit in a positive time sequence and then, allows the signal to be transmitted through another transmission circuit having the same transmission characteristics in a reverse time sequence with respect to the positive time sequence. Also, while the transmission circuit is arranged to have a zero-phase characteristic, each segment of a continuous signal is processed throughout a period which is equal to at least two times a duration of an impulse response direction of the transmission circuit. Accordingly, unwanted wave errors appearing at discontinuous regions of the signals are eliminated.

摘要： At least three heads are mounted on a rotary drum. Between the first and third heads which are located in close proximity to each other and have different azimuth angles, a minute height difference is formed in the rotation shaft direction of the rotary drum. Signals of a plurality of data rates are recorded and reproduced by using the first and second heads or the first and third heads. Two heads having the same azimuth angle are disposed on the rotary drum so as to be opposed each other at a central angle of 180°. In search speed reproduction, search data are reproduced by the two heads. Tracks are divided in the unit of plural tracks so as to form track sets. Search data areas of each track set are disposed at a position of each track which is separated from the edge of a tape by a predetermined distance. In search speed reproduction, the phases of the tracks and the heads are controlled, and all effective data of the search data areas are reproduced by plural scans of the heads.

摘要： When transmitting encoded video data and audio data, a transmitter 201 also transmits a decoding method 107 generated by decoding-method generation means 203. In the case of a receiver 202, decoding control means 111 controls decoding means 208 in accordance with a received decoding method 113 and thereby, decodes video data and audio data 115. Thus, it is unnecessary for the receiver 202 to previously prepare all of a plurality of decoding methods and the transmitter 201 does not need to encode video data or audio data in accordance with the decoding method owned by the receiver 202.

摘要： In a video signal recording/reproducing apparatus for recording and reproducing two-channel component signals, input two-channel component signals are processed separately from each other by two recording signal processing circuits to be recordable two-channel component signals. The recordable two-channel component signals are exchanged at predetermined intervals by a first switching circuit to be two combined signal each containing the recordable two-channel component signals which appear at periods corresponding to the exchanging invervals. The two combined signals are recorded on a recording medium via recording heads and reproduced from the recording medium via reproducing heads. The reproduced two combined signals are exchanged at the predetermined intervals by a second switching circuit to be the recordable two-channel component signals, which are thereafter processed separately from each other by two reproduced signal processing circuit to be the original two-channel component signals.

摘要： A PLL circuit for a phase comparator, a low-pass filter (LPF), a voltage-controlled oscillator (VCO) and a frequency divider. A first control circuit is responsive to a discontinuous phase change of a reference signal of the PLL circuit for inhibiting the operation of the phase comparator or disconnecting the LPF from the phase comparator during a predetermined period so that the discontinuous phase change information is not transmitted through the LPF to the VCO. At the same time, a second control circuit resets the frequency divider by a pulse of the reference signal after the discontinuous phase change or applies a voltage corresponding to the discontinuous phase change to the VCO so that the output signal of the frequency divider is locked in phase to the reference signal after the discontinuous phase change. With the cooperation of the first and second control circuits, the PLL circuit quickly recovers its stable state after the discontinuous phase change of the reference signal.

摘要： A video signal recording/reproducing apparatus has, in a recording signal processing section, a first switching circuit for exchanging 2-channel component signals at intervals of nH (n: any integer, H: horizontal scanning period) to obtain two combined signals each containing the 2-channel component signals which appear alternately at periods of nH, and a first delay circuit for delaying one of the two combined signals by nH so that the same kind of signals appear at same timings in the two combined signals. The two combined signals one of which is delayed by nH will not be interfered with each other by crosstalks therebetween which will occur in the subsequent circuits including recording and reproducing heads. A reproduced signal processing section has a second delay circuit for delaying by nH a reproduced combined signal which corresponds to the combined signal which has not been delayed in the recording signal processing section so as to recover the original timing relation between reproduced two combined signals, and a second switching circuit for exchanging the reproduced two combined signals one of which is delayed by nH by the second delay circuit at intervals of nH to obtain the original 2-channel component signals.

摘要： In a video tape recorder of the color under recording type, in which a low frequency band converted carrier chrominance signal is recorded together with an FM luminance signal, another FM modulator is provided for modulating a wide band chrominance signal. An additional head records the FM chrominance signal on at least a part of a track on which video signal has been recorded in the color under recording. In reproduction, it is checked whether the FM chrominance signal is reproduced or not for selecting the FM chrominance signal or the color under recorded carrier chrominance signal as a reproduced chrominance signal output.
