摘要： A system for transmitting or recording and reproducing a frequency modulated wave suppresses beats produced by a carrier wave and a signal component of high energy level distribution, which is disposed in a range of higher frequencies of a wave signal. A frequency component, which is liable to be reproduced as a beat signal, is subjected to pre-emphasis. A demodulated signal obtained by demodulating the frequency modulated signal is subject to deemphasis with a characteristic opposite to the preemphasis characteristics applied to the wave signal. Thus the frequency-phase characteristics of the signals is uniform throughout the system, whereby the influence exerted by moire beat interference on the demodulated signal can be minimized.

摘要： In a de-emphasis circuit designing method for minimizing the number of peripheral components of a video signal processing integrated circuit (IC), a circuit device for determining the level of a reproduced video signal of the de-emphasis circuit is included in the video signal processing IC. The number of components is reduced by designing all circuit elements of the circuit device for determining the level of the reproduced video signal of the de-emphasis circuit so that they are incorporated into the video signal processing IC at the time of design of the video signal processing IC, thereby reducing cost and reducing any deviation in the playback (PB) level due to external component deviation. The video signal processing IC comprises the de-emphasis circuit and a video level setting unit, the latter comprising an amplifier connected to an output of the de-emphasis circuit, a plurality of resistance elements, and a plurality of respective switches for ON/OFF switching of the resistance elements, thereby setting the gain of the amplifier and the level of the reproduced video signal.

摘要： There is provided a video cassette recorder comprising a delay element (1), a switching unit (2) for switching an output of the delay element (1), a logic unit (3) for controlling the switching unit (2), and a skew detection unit (4) for detecting a skew, wherein the delay element (1) shares a delay element used for vertical emphasis/vertical de-emphasis and for a comb line filter during a special replay. The video cassette recorder thus provides a fast-forwarding replay image, a rewinding replay image and a still image with improved skew distortion from a tape recorded in a long recording mode providing quintuple the recording time of a standard mode. This realizes an excellent special replay image at low cost without requiring an expensive circuit such as a TBC and the like.

摘要： A video signal recording system is disclosed which includes a circuit for generating a control signal representative of the level of the high-frequency portion of a full-bandwidth luminance signal. An adaptive deemphasis circuit reduces the level of the high-frequency portion of the luminance signal in response to the control signal. A folding circuit folds the high-frequency portion of the deemphasized luminance signal into the low-frequency portion. The folded deemphasized luminance is combined with the control signal and recorded on the video tape. A video signal playback system is disclosed which includes a circuit for separating the previously recorded control signal from the previously recorded folded deemphasized luminance signal. An unfolding circuit unfolds the played back luminance signal to produce a wide bandwidth deemphasized luminance signal. An adaptive reemphasis circuit boosts the level of the high-frequency portion of the unfolded luminance signal in response to the separated control signal.

摘要： A video signal recording and reproducing apparatus comprises a magnetic tape (4) into which video signals are recorded. A preemphasis circuit (35) modifies the video signals prior to the recording into the magnetic tape (4), so as to increase magnitude of high-frequency components with respect to magnitude of low-frequency components on time base. A record start or end ID signal is generated in response to a record start or end signal in an ID signal recording circuit (36) which memorizes this ID signal into a corresponding portion of the magnetic tape (4). A mute circuit (46) resets the preemphasis circuit (35) in response to the record start or end signal. There is further provided a deemphasis circuit (37) for modifying the video signals after reproducing from the magnetic tape (4) in a complementary manner with respect to the preemphasis circuit (35), so as to decrease magnitude of high-frequency components with respect to magnitude of low-frequency components on time base. An ID signal detecting circuit (38) detects the record start or end ID signal from the magnetic tape (4) and generates an ID detecting signal. A mute circuit (49) resets the deemphasis circuit (37) in response to the ID detecting signal.

摘要： An image is stably reproduced in a special reproduction mode of still, frame advance or slow motion mode without residual image and/or blur. A video signal reproducing apparatus operates to alternately repeat the steps of interrupting a de-emphasizing process at a time at which the de-emphasis process for one video image signal period is completed, holding a content of a frame memory constituting the de-emphasis circuit without refreshing the content and performing a de-emphasis process based the content of the memory during a subsequent video image signal period.

摘要： A method and an apparatus by which a panorama image is produced with a high degree of accuracy from an image signal are disclosed. An image signal produced by a CCD imaging element is recorded onto a video tape by way of a camera signal processing circuit, a recording signal processing circuit, a recording/reproduction amplifier and so forth. Meanwhile, a microcomputer calculates of a motion vector of an image from the output of a motion vector detector to which the image signal from the CCD imaging element is inputted, and controls a video subcode processor so that motion vector information may be recorded onto the video tape. The motion vector information is reproduced from the video tape together with the image signal, and a plurality of images are formed from the thus reproduced image signal and joined together in accordance with the motion vector information to produce a panorama image.

摘要： A digital VTR using Automatic Track Finding (ATF) of a four frequency pilot signal system, employing a multiple segment recording system for high density recording and wide band recording. In a recording mode, a segment code signal is recorded on each track in response to a frame synchronizing signal. In a reproduction mode, the phase difference between the reproduced segment code signal and the frame synchronizing signal is detected by phase comparing circuit 26. The rotation speed of capstan motor 29 is controlled so that the phase relation of one signal in the reproduction mode becomes the same as that in the recording mode. As a result, it is possible to reproduce a stable video in the VTR using the segment recording system.
