摘要： An identification signal is produced on the basis of the difference between the potentials in the adjacent horizontal blanking periods of a demodulated line sequential color signal. Therefore, adelay, if, of the discrimination timing can be substantially ignored when compared to the system using narrow- bandpass filters, and the color signals can be accurately discriminated without delay. Further, by the virtue of the provision of the horizontal scanning period rate conversion circuit, a pulse which is synchronous with the horizontal signal and appears accurately at the time interval of one horizontal scanning period is based on for effecting the accurately desired discrimination, so that the discrimination can be reliably effected at the desired posotion without an adverse effect of noise, a dropout in magnetic recoding or the like.

摘要： A clamping circuit (42, 44) for use in a line sequential video processor (73) sets separate dc voltage levels for a pair of color difference signals (B-Y, R-Y). The respective dc levels serve to identify the sequence of the color difference signals in the line sequential signal. By first setting the voltage offset between the respective levels, the dc voltage levels for both color difference signals are later established by clamping only to every other signal. The clamping circuit includes a monostable multivibrator (103) that generates a clamping pulse only at the onset of every other color difference signal.

摘要： A video signal processor used for a recording/reproducing apparatus such as a video tape recorder that includes decoder (36) and encoder (16), or an apparatus for transmitting video signals. The video signal processor divides a composite video signal into a luminance signal and two chrominance signals. At the time of decoding, the video signal processor transmits data signals that indicate the phase of chrominance sub-carrier waves in the composite video signals. At the time of encoding, the video signal processor controls the relation of phase between the composite video signals and the chrominance sub-carrier waves relying upon the data signals, so that the high level of the luminance signal and the chrominance signals have no distortions or minimum ones.

摘要： An apparatus and method are provided for encoding and decoding video signals on a conventional magnetic recording medium in a manner whereby the decoded video signal includes an improved chrominance characteristic. The improved chrominance characteristic is provided by encoding the conventional luminance and chrominance information signals on a first track of the information recording medium for the odd alternate fields and a modified luminance information signal and a select separate color component signal on a second track of the information recording medium. The signal recorded on the first track of the recording medium may be decoded in a conventional manner to provide video signals of limited chrominance video bandwidth or, alternatively, both tracks of the recording medium may be decoded in the manner of this invention to provide an improved chrominance characteristic video signal.

摘要： The present invention relates to a video tape recorder for recording video signals on a magnetic tape.
The tape recorder, rather than recording F.M. luminance signals and F.M. chrominance signals on separate tracks as is conventionally done, records the signals on the same track, sections of luminance signal and sections of chrominance signal being alternated along the track. Recording the signals in this manner does away with the necessity to provide guard bands between adjacent tracks, and also allows one to apply a slant azimuth recording technique because the signals on adjacent tracks are well correlated.

摘要： A circuit for producing a chroma signal which includes both of a first (R-Y) and a second (B-Y) color difference signal on each of scanning lines in response to a line-sequential color difference signal in which a first and a second color difference signal appear alternately on consecutive scanning lines. A carrier generator (40, FIGS. 3 and 5) generates a first (SC2a) and a second (SC1a) color subcarrier which are different in phase from each other in synchronism with the line-sequential color difference signal. The first color subcarrier (SC2a) is subjected to balanced modulation at a first modulator (60) which uses the first color difference signal (R-Y) for the modulation while the second color subcarrier (SC1a) is subjected to balanced modulation at a second modulator (66, 68, 70) which uses the second color difference signal (B-Y). The outputs of the first (60) and second (66, 68, 70) modulators are added together by a first adder (74). A delay circuit (80) is provided for delaying an output of the first adder (74) by a period of time which is substantially equal to one horizontal scanning period. The output of the delay circuit (80) is added to the output of the first adder (74) by a second adder (82) to produce the chroma signal. The circuit eliminates the need for operations heretofore performed for bringing color difference signals into coincidence at the baseband and thereby the need for delay circuits, switching circuits and adjusting circuits which implement such operations.
