摘要： A video signal recording and reproducing apparatus includes a first device for inputting a video signal and a second device for recording the video signal as component signals. In addition, a third device serves to generate a color frame signal from color frame information contained in the video signal. A fourth device serves to record the color frame signal. A fifth device serves to reproduce the component signals and the color frame signal. A sixth device serves to output the reproduced component signals and the reproduced color frame signal.

摘要： A portable video tape recorder for broadcasting applications comprises a pair of video heads (B, B') mounted diametrically opposite to each other on the circumference of a rotary cylinder. High and low frequency carriers are modulated by frequency modulators (5,6) with I and Q signals, respectively, and frequency division multiplexed for application to the video heads. The frequency values of the carriersare selected so that third-order distortion noise caused by the hysteresis characteristics of the video heads and the magnetic tape may fall within a frequency range higher than the frequencies of the modulated carriers by an amount greater than the bandwidth of the I and Q signals which are demodulated by frequency demodulators (49, 50; 39, 40) to prevent the occurrence of beat interference in the frequency band of the reproduced video signal.

摘要： In a video tape recorder, luminance and chrominance signals are recorded respectively by first and second transducer heads (A, A'; B, B') along separate tracks skewed to the direction of tape motion. The transducer heads are rotated in a different tape-head speed relationship during extra modes such as slow-motion or still picture reproduction from the normal tape-head speed relationship, causing the transducer heads to traverse several tracks. A switching circuit (16) is coupled to the transducer heads to selectively connect the outputs of the heads to an output circuit (23, 28) in response to a point of transition of amplitude of the output signal from the second head (B, B') to cancel unwanted signal components detected by the heads during traversal across the tracks.

摘要： An apparatus for recording signals through forming oblique tracks on a recording medium with recording set heads composed of a plurality of heads which are adapted to have different azimuth angles among the adjacent tracks, wherein guard bands are not provided among the respective tracks which become sets to be recorded by a plurality of heads constituting the recording sets, but in at least an editing point, a guard band is provided among set tracks recorded by the recording set heads and the already recorded set tracks so as to effect the recording operation, whereby the interference at the editing point is reduced, the track shift tolerance at the editing time from the conventional VTR is increased.
