摘要： For improving the frequency characteristic of a color television signal, particularly one in which the chrominance component thereof is provided with a bandwidth substantially narrower than that of the luminance component, the luminance component is used to generate a control signal which is proportional to the lack of registration between low and high frequency portions of the luminance component spectrum, and the control signal thus obtained selectively increases and decreases a delay applied to the relatively narrow-bandwidth chrominance component to substantially align its excursions with the excursions of the relatively wide bandwidth luminance component.

摘要： In a video signal reproducing apparatus having a cathode ray tube in which at least one electron beam is made to scan a screen in line-scanning and vertical directions while the intensity of the beam is modulated to establish the brightness of a video picture to be displayed on the screen, and in which bright picture portions are represented by respective high level portions of a video signal defined between rising and falling edges extending from low level signal portions representing contiguous dark picture portions; a waveshaping circuit receives the video signal and acts thereon to provide a compensated video signal in which the width of each high level portion between the respective rising and falling edges is increased, the compensated video signal is employed to control the intensity of the electron beam, the rising and falling edges of each high level portion of the video signal are detected to provide a beam velocity modulation signal with respective positive and negative peaks by which the scanning velocity of the beam in the line-scanning direction is modulated, and the positions of such positive and negative peaks are shafted, relative to the corresponding peaks of a differentiation of the video signal, in the directions toward the adjacent low level signal portions of the compensated video signal.

摘要： In apparatus for reproducing color video signals recorded in successive parallel tracks on a record medium with the chrominance components of video signals recorded in next adjacent tracks having first and second carriers which differ from each other in respect to their phases or polarity characteristics; and in which a plurality of transducers scan along the tracks one at a time so as to reproduce the video signals recorded in each of said tracks along with cross-talk signals from the tracks next adjacent thereto, means for separating said chrominance signal components from the luminance signal component in the reproduced signals, and a signal processing circuit including a switching circuit and a comb filter provides the separated chrominance components of video signals reproduced from each of said tracks with a common carrier and eliminates therefrom the chrominance components of the cross-talk signals on the basis of said different phases of the first and second carriers with which the chrominance components were recorded in the tracks which are next adjacent to each other: the changing-over of the switching circuit is controlled in response to the phase of the chrominance component carrier that results therefrom so as to ensure phase alignment of the common carrier with which the chrominance components of the video signals reproduced from the successive tracks are provided. Further, control signals are recorded on the record medium to identify those tracks in which video signals are recorded with their chrominance components having said first and second carriers, respectively, and, on reproducing, such identifying control signals are reproduced to control the movements of the transducers and, through such controlled movements, to regulate the changing-over of the switching circuit.

摘要： In reducing crosstalk between the low frequency, frequency-converted chrominance portions of h-aligned video signals on adjacent tracks, the frequency converting carrier, but not the entire frequency converted portion, has its polarity inverted at the end of each line interval during the recording of alternate tracks but not during the recording of the remaining alternate tracks. This eliminates the extraneous signal that would otherwise be produced in the balanced modulator of the playback apparatus by any direct voltage offset or transient remanent of a direct voltage offset in the recorded signal.
