摘要： PURPOSE: To obtain a normal regenerated image having no color disappearace or hue confusion by setting a intermittent recording scale factor at an odd number in case of intermittently magnetically recording a video signal of PAL or SECAM system.
CONSTITUTION: A figure shows a relation between a frame number in intermittently recording a video signal of PAL system by 9 times of intermittent recording scale factor and an odd line burst phase and the odd line burst phase is reversed every frame. It is easily understood that when setting at an odd number except 9 times of the intermittent recording scale factor, the odd line burst phase is reversed every frame similarly thereto. Accordingly, if the intermittent recording scale factor is set at an odd scale factor, the relation between the frame number and the odd line burst phase becomes always normal and a normal regenerated image picture having no color disappearace of a hue confusion is obtained.

摘要翻译：目的：通过在间歇地记录PAL或SECAM系统的视频信号的情况下，通过设置奇数的间歇记录比例因子来获得没有颜色消失或色调混淆的正常再生图像。构成：图示出间歇地记录PAL系统的视频信号的帧数与间隔记录比例因子的9倍与奇数行脉冲串相位之间的关系，奇数行脉冲串相位每帧反转一次。容易理解，除了间隔记录比例因子的9倍之外，当设置为奇数时，与其类似地，每帧的奇数行脉冲串相位反转。因此，如果将间歇记录比例因子设定为奇数比例因子，则帧数与奇数行脉冲串相位之间的关系变得总是正常，并且获得没有颜色消失的色调混淆的正常再生图像图像。

摘要： PURPOSE:To suppress mutual interference between a sound signal and a video signal by smoothing record equalizing characteristics for a luminance signal, inserting a comb line filter to a liminance signal circuit and connecting a recording chroma signal circuit to a chroma signal equalizing circuit. CONSTITUTION:Parts 20, 21 are a luminance signal (YFM) extracting LPF and a chroma subcarrier suppressing comb line filter respectively and a circuit 22 uniforms synchronous peak potential and smoothes the characteristics of circuits 24, 25. A luminance signal YFM is obtained from the output of a frequency modulation circuit 27. On the other hand, parts 30, 31 are a chroma signal (CL) extracting BPF and a YFM suppressing filter respectively. A part 39 is a CL recording equalizer and a part 41 is a sound signal compressing circuit. Since said constitution prevents the emphasis of the lower band wave of the YFM, the lower band wave is not leaked into a band of an AFM. In addition, connection of a compressor 41 to a sound circuit prevents a sound signal from being distorted by the YFM. Since the CL recording equalizer 39 suppresses the upper wave of the CL, the distortion of the sound signal by the CL is resolved. Smoothing recording current for the YFM suppresses noises due to the DP (differential phase) of a head system and a circuit 35 in the CL circuit prevent leakage from the sound circuit.
摘要翻译：目的：通过平滑亮度信号的记录均衡特性来抑制声音信号和视频信号之间的相互干扰，将梳状滤波器插入限位信号电路，并将记录色度信号电路连接到色度信号均衡电路。构成：部件20,21是分别提取LPF和色子副载波抑制梳状线滤波器的亮度信号（YFM），并且电路22均匀同步峰值电位，并使电路24,25的特性平滑化。从...获得亮度信号YFM 输出频率调制电路27.另一方面，部分30,31分别是提取BPF和YFM抑制滤波器的色度信号（CL）。部分39是CL记录均衡器，部分41是声音信号压缩电路。由于所述结构防止YFM的低频波的强调，所以较低频带波不会泄漏到AFM的频带中。此外，压缩机41与声音电路的连接防止声音信号被YFM扭曲。由于CL记录均衡器39抑制CL的上部波，所以解析了CL的声音信号的失真。用于YFM的平滑记录电流抑制由于头系统的DP（差分相位）引起的噪声，并且CL电路中的电路35防止来自声音电路的泄漏。

摘要： PURPOSE:To obtain a continuous wave coincident with the initial phase of an intermittent input signal, by shifting the phase of a signal by means of plural multipliers, LPFs, sample holding circuits and continuous wave oscillators. CONSTITUTION:A multiplier 13 compares the phases between a carrier wave S1 given from an oscillator 11 and a burst signal S2 given from an input terminal 12. A multiplier 15 compares phases between a signal obtained by giving a 90 deg. phase shift 14 to the wave S1 and the signal S2. The outputs of multipliers 13 and 15 are led to sample holding circuits 18 and 19 via LPF16 and 17 respectively. An output signal S4 of the circuit 18 is compared with the signal S1 through a multiplier 21 in terms of phase, and at the same time an output signal S5 of the circuit 19 is compared with the S1 by a multiplier 22 respectively. Signals SM1 and SM2 obtained from those phase comparisons are added together 23, and therefore a signal S0 is delivered through a terminal 24.

摘要： PURPOSE:To prevent deterioration of a picture quality, by compensating and dubbing a time axis of a reproduced luminance signal and a chrominance signal, making a local horizontal synchronizing signal a reference. CONSTITUTION:A reproduced luminance signal which is obtained by an output of an LPF19 is led to a CCD33, and is led to a horizontal synchronization separating circuit 29, as well. By an output of the circuit 29 is obtained a horizontal synchronizing signal having jitter which is contained in the luminance signal. On the other hand, to a terminal 30 is provided a local reference horizontal synchronizing signal, and a luminance signal whose time axis is compensated by an output of the CCD33 through a VCO32. In this same way, an I signal and a Q signal whose time axis and timing are compensated are obtained by outputs of CCD39, 40. These signals are dubbed by other VTR through a dubbing terminal 41.

摘要： PURPOSE:To obtain a stable reproducing picture image without skew distortion and color disappearence by compressing a time axis of a video signal, reducing the width of a video signal and recording the result on a magnetic tape. CONSTITUTION:A recording track length lT of a conventional magnetic recording device is reduced to a recording track length lN of a conventional VTR and H arrangement is applied. The 263rd signal 263 is divided into two and they share the last part and the first part of the adjacent track of one field. Through the apparent constitution (from the standpoint of a conventional VTR), the length of signal missing part at head switching corresponds to 1H and no skew distortion and color disappearence are caused by the reproduction of the conventional VTR.
