摘要： In a video signal recording/reproducing apparatus, a video signal is subjected to bit rate reduction including a variable length processing to obtain a coded data. The coded data is separated into basic data which shows a basic construction of a video image and has a fixed data length and additional data which shows detailed information of the video image and has a variable data length. In recording the coded data containing basic data and additional data on a recording medium, the basic data is recorded in one region on the recording medium and the additional data is recorded continuously in a region other than the basic data recording region, by which both data are recorded in separated regions on the recording medium.

摘要： In a digital signal magnetic recording/reproducing apparatus, input digital signals of plural channels and a recording current control signal expressing recording current values corresponding to the respective digital signals are time-division mulitplexed and transmitted into a rotary cylinder, and the digital signals and recording current control signal are separated by a circuit built in the rotary cylinder. The recording current for each of the digital signals is controlled depending on the recording current control signal. By time-division multiplexing the input digital signals of plural channels and transmitting the multiplexed signal into the rotary cylinder, the number of channels of the rotary transformer can be reduced. Further, by transmitting the recording current control signal into the rotary cylinder, the recording current of the digitally transmitted signal can be adjusted.

摘要： A two speed or multi-speed video tape recorder of the conventional helical scan type in which the audio signal is capable of being recorded as a time compressed signal at one end of each helical video scan, or alternatively, in conventional longitudinal fashion by means of a stationary magnetic head engaging one edge of the tape.At low tape transport speeds, improved bandwidth (and therefore sound fidelity) is obtained by use of the time compression technique; while at higher transport speeds, there are advantages in utilizing the stationary audio head.Circuitry is provided to automatically utilize the time compression technique at lower tape transport speeds and the stationary head longitudinal recording technique at higher tape transport speeds. A pilot or cue signal is recorded on the tape, to automatically control the reproduction circuitry so that both types of recording methods can be interchanged on the same magnetic tape, with the reproducing circuitry switching accordingly between the two modes, as required.

摘要： A video recording and reproducing apparatus with photoelectric image camera in which a color signal processing circuit of a recording system is simplified. For recording, a luminance signal and a chrominance signal are produced in accordance with an image being picked up through a photoelectric transducer. The luminance signal is angle-modulated, while a carrier signal having a lower frequency than the standard carrier signal is directly modulated with the chrominance signal, whereby a chrominance recording signal equivalent to a signal obtained by a frequency conversion of the standard carrier signal to a low frequency band is obtained and added with the angle-modulated luminance signal to be recorded. Upon reproduction, the angle-modulated luminance signal undergoes angle-demodulation to be converted to a reproduced luminance signal, while the color (chrominance) recording signal is frequency-converted to a high frequency band to be reproduced color signal. The reproduced luminance and color signals are added together to obtain a reproduced color video signal.

摘要： A magnetic recording and reproducing apparatus, for recording and reproducing the color television signal including VIR signal, of the type having a comb filter which is inserted in the chrominance signal system and includes a delay line for causing a delay equal to one horizontal line scanning period. In this apparatus the VIR signal has no line correlation so that the output of the comb filter becomes a VIR signal the amplitude of which is reduced by 6dB and that the amplitude and/or phase of the chrominance components of VIR signal are caused to vary over a wide range due to the effects of VIT signal. In order that the stable and correct color images may be reproduced even by a color television receiver of the type in which the amplitude and phase of the chrominance components of VIR signal are detected so as to automatically adjust the color saturation and hue, the amplitude of the chrominance components of VIR signal is detected and corrected in a recording system of a magnetic recording and reproducing apparatus; the burst signal and the chrominance components of VIR signal are compared in phase so as to correct the phase of the carrier color signal with the difference signal before the carrier color signal is recorded; and in the playback mode the chrominance components of VIP signal of the carrier color signal free from time axis distortions are replaced with the stable oscillator output.

摘要： In a magnetic recording and reproducing device having at least one rotating magnetic head for recording and reproducing video signal and digital form audio signal in a contiguous manner along each track which is inclined at an angle relative to the direction of travel of a magnetic tape, a discriminator signal is combined to the digital form audio signal. The discrimination signal has a first section carrying a check code and a second section carrying information. During the reproducing mode, the discrimination signal is detected such that the information carried in the second section is made invalid when the check code has a predetermined code pattern, and the information carried in the second section is made valid when the check code has a code pattern other than the predetermined code pattern. Furthermore, the check code is used to indicate the type of information contained in the second section.
