Abstract: PURPOSE:To ensure an excellent S/N and a wide dynamic range of the sound signal, by supplying the FM modulated sound signal to a rotary magnetic head with no mixture with a video signal and recording the sound signal at a high recording level. CONSTITUTION:Left and right signals SL and SR are modulated by FM modulators 6 and 7 as well as 11 and 12 and turned into FM modulated left and right signals of different frequency deviation bands. The signals LF1 and RF3 supplied from BPFs 13 and 15 are mixed together by a mixing circuit 17. The signals LF2 and RF4 are also mixed in the same way. Each mixture output and video signal are supplied to mixing circuits 21 and 22 and then recorded. In this case, the gains of variable gain amplifying circuits 18 and 20 are controlled with a control signal P, and the level of each mixture output is considerably reduced compared with the video signal. Thus the interferece is reduced to the video signal. When the recording is carried out with no mixture with the video signal, only the mixture output is supplied to the circuits 21 and 22 by a control signal Q. Then the gains of the circuits 18 and 20 are controlled, and the mixture output is supplied to the head with a sufficiently high level compared with the recording with mixture of the video signal. Thus, both S/N and dynamic range are improved.
Abstract translation: 目的：通过将FM调制声音信号提供给不带视频信号的旋转磁头，并以高记录级别录制声音信号，确保良好的信噪比和广泛的动态范围。 构成：左右信号SL和SR由FM调制器6和7以及11和12调制，并转换成不同频率偏移频带的FM调制左和右信号。 从BPF 13和15提供的信号LF1和RF3通过混合电路17混合在一起。信号LF2和RF4也以相同的方式混合。 每个混合输出和视频信号被提供给混合电路21和22，然后被记录。 在这种情况下，利用控制信号P控制可变增益放大电路18和20的增益，并且与视频信号相比，每个混合输出的电平显着降低。 因此，干扰减少到视频信号。 当与视频信号不混合进行记录时，仅通过控制信号Q向电路21和22提供混合输出。然后控制电路18和20的增益，并且提供混合输出 与具有视频信号混合的记录相比，具有足够高的电平。 因此，提高了S / N和动态范围。

Abstract: PURPOSE: To take a state in which a desired unit partition period set as a frame period in a video signal is precisely and surely taken out by memory and a prescribed control circuit. CONSTITUTION: A memory part 24 repeats an operation to store plural frame periods of the video signal sequentially. A frame selection part 28 is operated so as to select the specific frame period of the video signal. A control unit part 20, when the frame selection part 28 being operated while the memory part 24 is operated, stores the prescribed number of frame periods and the prescribed number of frame periods arriving afterwards before the frame period being stored at that time, and also, stops the storage of another frame period, and sets a state in which stored plural frame periods are read out.

Abstract: PURPOSE:To attain the partial rewriting at all times with no erroneous recording by detecting the record mode set when a track is formed out of the part immediately before a reproduction system by said reproduction system when the partial rewriting record is carried out and performing the rewriting record in the same record mode. CONSTITUTION:When the partial rewriting is carried out, a command signal U is trasmitted from n action control part 3. In this case, a reproduction mode is set before transmission of the signal U. It is defined that a record mode is set at a recorded part immediately before the partially rewriting part of a magnetic tape and when an oblique track is formed for the discrimination signal R sent from an FM sound signal existence discriminating circuit 37. Such signal R is held by a preholding circuit 63. Then recording reproducing switches 5-7 are switched when the signal U and the control signal P' are transmitted from the part 3. Thus the partial rewriting is performed for the color video signal which is supplied to an input terminal 2 in accordance with the signal R held at the circuit 63.

Abstract: PROBLEM TO BE SOLVED: To simplify the operation in the case of printing out a still image by using a detection means to detect whether video information VS is a moving image or a still image, allowing the user to depress a memory button and a print button when the information is a moving image and to depress only the print button when the information is a still image. SOLUTION: When a power button of a video printer 20 is depressed, a moving image or a still image of a current video signal VS of a video equipment is displayed on a monitor 9. Whether the input video signal BS is a moving image or a still image is discriminated. The discrimination is conducted manually by the user and a changeover switch 14 is operated or a still image/ moving image detection circuit 13 is used to detect a motion of the input image for automatic discrimination. When the input image is discriminated to be a still image, a CPU 6 allows the monitor to display a guidance of depressing a print button 5a and also its still image immediately. When the user depresses the button 5a according to the guidance, the input still image is stored in a memory 4 and the CPU 6 allows a thermal head 12 to print out the image.

Abstract: PURPOSE:To prevent the deterioration in picture quality by providing a means decreasing the part where a magnetic track recorded already is erased by overlapping the final magnetic tracks at the inserting edition and recording in a tracking servo circuit. CONSTITUTION:A movable contact (m) of a changeover switch SW1 is switched to a reproducing side fixed contact (p) at the inserting edition and recording and a movable contact (m) of a changeover switch SW2 is switched to a recording side fixed contact (r). Further, a control signal being at a high level during the insertion edition and recording is applied to an input terminal 11, a transistor 9 turns on and a capacitor 8 is connected in parallel with a capacitor 7. Thus, the amount of delay in a delay circuit 3 is different from that at normal recording and the recording position of the magnetic track at the insertion edition and recording is shifted as a whole.

Abstract: PURPOSE:To stable the carrier frequency, by correcting the oscillating frequency while no modulated signal is supplied and having a control so that the corrected frequency is maintained as a center frequency even when the modulated signal is supplied. CONSTITUTION:Switches 2 and 9 are turned off and on respectively with a switching signal W. Then the output of a voltage control oscillator 5 is compared with that of a reference oscillator 7 by a phase controller 6. Those compared outputs are connected to the control input terminal of the oscillator 5 through a filter 8 via a buffer part 10. Under such conditions, the oscillating frequency of the oscillator 5 is corrected to the frequency of the oscillator 7. When the switches 2 and 9 are turned on and off respectively with the signal W, a modulated signal S is applied to the control terminal of the oscillator 5. In this case, the output voltage of the filter 8 obtained during correction is held at a capacitor 11 and then applied via the buffer 10. Therefore a carrier frequency is equal to the frequency of a reference signal.
