摘要： A video signal processing apparatus, typically for use as a video tape recorder/reproducer for recording and reproducing high-definition television signals, includes an encoder for converting a chrominance signal into a line sequential signal, time-compressing the line sequential signal and multiplexing the time-compressed line sequential signal with a luminance signal according to time-division multiplexing, thereby producing a time-division-multiplexed signal. A vertical emphasis circuit is connected to an input terminal of the encoder, for performing vertical nonlinear emphasis on the chrominance signal. The video signal processing apparatus also includes a vertical low-pass filter for preventing aliasing distortions from the chrominance signal due to the conversion of the chrominance signal into the line sequential signal. The vertical nonlinear emphasis is performed on the chrominance signal after the chrominance signal has been processed by the vertical low-pass filter.

摘要： Disclosed is a VTR of the helical scan type having a plurality of rotary magnetic heads. This VTR can select one of a first and a second signal recording forms which are different from each other, and record signals on a magnetic tape. In the first recording form, a frequency-modulated video signal including a luminance signal and a color signal and a frequency-modulated sound signal are recorded on the same track so as to be superimposed one on the other. In the second signal recording form, a frequency-modulated luminance signal and a frequency-modulated color signal are recorded separately on tracks adjacent to each other. This VTR has compatibility with respect to the recording/reproducing of two different signals.

摘要： A component video signal transmitting apparatus for suppressing any adverse affects caused by noises which are mixed with FM signals which are transmitted after component video signals are frequency modulated. After the color difference signals (P b and P r ) in the component video signals are previously expanded (10, 11) in level in a high level region, they are frequency modulated and transmitted (1). The high level expanded color difference signals extracted by demodulation (2) of the transmitted signals are compressed (20, 21) in level at the high level region.

摘要： A display method and apparatus are provided for enabling a user, whether or not he has experience, to readily detect a luminance level of a video image with high accuracy. A luminance level of a video signal of a video image is converted to color information to display a change in the luminance of the video image as a change in color. The conversion preferably involves a method of converting the luminance level to color information of three primary colors, red, green, blue, in accordance with a plurality of weights, respectively, a method of converting a luminance level in a predetermined range to color information having a changing rate larger than a changing rate of the luminance level, a method of converting a luminance level out of the predetermined range to color information of a maximum or a minimum level, or the like. Also, the input video signal is preferably displayed together with a converted video image side by side or one on another.

摘要： A color video signal composed of successive groups of analog color samples, successive samples in at least some of said groups alternating between one color and another, wherein such groups represent successively scanned rows or lines of video frames or fields, is processed, prior to recording, by assigning respective samples to one of a plurality of channels of substantially equal bandwidth in a manner such that respective channels contain subgroups of samples representing only one color per subgroup, thereby minimizing the power at the sampling frequency in such channels. The information in the channels is recorded on a corresponding plurality of tracks on a recording medium by multi-channel essentially-fixed-head recording apparatus thereby realizing the manufacturing economy of essentially-fixed-head type apparatus. In one embodiment of the invention, samples of a first color occur more frequently in the color video signal than do samples of a second color, thereby maximizing the utilization of the information storage capacity of the recording medium.In a preferred implementation, the color video signal is generated by a solid state image sensing array having discrete image sensing elements selectively sensitized to green, red, or blue. Green-sensitive elements occur more frequently in the array than do red- or blue-sensitive elements in recognition of the fact that human visual acuity is higher for green, than for red or blue. The signal is separated sample-by-sample and the samples assigned to eight channels in a manner such that for each group of samples, the samples representing green (green samples) occupy four of the eight channels, and the samples representing red (red samples) and/or blue (blue samples) occupy the other four channels.

摘要： A recording/reproduction system performs high precision drop-out processing and compensation in the reproduction mode from a disk-shaped recording medium by using a recording format in which a video signal is divided alternately in units of one horizontal scan line into two channels, and the timing of the recorded video signal on one channel is displaced relative to that of the other channel, so as to record the divided signals on a pair of parallel spiral tracks forming the two channels on the disk. A mean value interpolation circuit is provided in each channel for drop-out compensation, and a portion of a reproduced signal of one channel is compensated by a compensation signal produced by the interpolation circuit of the other channel.
