Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a video signal recording apparatus and a recording/reproducing apparatus.
In particular, the present invention relates to a video signal recording device and a recording/playback device that perform only recording or recording/playback without converting into a composite color video signal state.

BACKGROUND OF THE INVENTION FIG. 3 shows a block diagram of an example of a conventional video signal recording and reproducing apparatus. First, the operation during recording will be described. A composite color video signal input from an input terminal 1 is supplied to a Y/C separation circuit 2 and separated into a luminance signal Y and a carrier color signal C, respectively. Is the separated H degree signal engineering or nfu? cis circuit 3, FM modulator 4, high-pass filter (hereinafter 1-I P
A frequency modulated luminance signal (FM
iii degree signal) and is supplied to the adder 6.

On the other hand, during recording, the separated carrier color signal is supplied to an ACC circuit 8 through a switch circuit 7 connected to the terminal R side, and after its level is adjusted, it is supplied to a balanced converter 9. Further, the horizontal period signal obtained by sequentially passing the separated luminance signal through a switch circuit 10 and a period separation circuit 11 connected to the terminal R at the time of recording is transmitted to a phase comparator 12 and an adder 1.
3. Phase O tract loop (PL) consisting of voltage 1i1111II oscillator (VCO) 14 and counter 15
L), and after being set at a predetermined frequency, the phase is shifted by 90 degrees every horizontal scanning period by the PS processing circuit 16, and the direction of the phase shift is reversed every field. Phase shift processing (Phase S
(hift processing) and the equilibrium degree il! It is supplied to the I unit 17. It should be noted that since the sweetener 24 is configured during recording, the addition 113 does not perform the caulking operation at time 8.

The balanced modulator 17 has a frequency t equal to the color fall transmission frequency of the standard color video signal from the generator 18 (therefore, in the case of the NTSC system, 3.579545 MHz, and in the case of the PAL system, for example, 4.433679 MHz). 's signal and a signal from the PS processing circuit 16 that has been subjected to the above-mentioned phase shift processing at a frequency of 40fH, for example, and the output signal is passed through a bandpass filter (hereinafter referred to as BPF) 19 (fs +40fH
) is supplied to the balanced modulator 9 as a signal with a frequency of As a result, the balanced modulator 9 uses a low-pass filter (hereinafter referred to as LPF).
) 20, a low-pass converted carrier color signal having a color subcarrier frequency of 4Of+ and subjected to the above phase shift processing is extracted. This low-pass conversion carrier color signal is frequency-division multiplexed with the FM luminance signal in an adder 6, and then in a recording amplifier 2.
1 to the head 22 and thereby recorded on the magnetic tape 23.

Next, the operation during playback will be explained. The edge frequency division multiplexed signal recorded on the magnetic tape 23 is reproduced by the head 25 and supplied to the LPF 27 and HPF 28 through the reproduction amplifier 26, respectively. The reproduced FM luminance signal divided into Ill waves by the HPF 28 is made into a reproduced luminance signal by the FM demodulator 29, and then is added through the de-emphasis circuit 30.
31, and is also supplied to the period separation circuit 11 through the switch circuit 10. During reproduction, the switch circuits 7 and 10 are respectively connected to the terminal P side, and the switch 24 is closed. Therefore, the output phase error voltage of the phase comparator 32, which corresponds to the phase difference between the output signal of the oscillator 18 and the output page 1 color burst signal of the burst sampling circuit 35 (described later), is transmitted to the adder 13 in the PLL through the switch 24.
supplied to From this PLL, there is a period separation circuit 11.

A signal that is phase-periodically synchronized with the reproduced horizontal periodic signal having a jitter of about 100% and is responsive to the phase shift of the reproduced colorverse I-signal is extracted and supplied to the balanced modulator 17 through the PS processing circuit 16, where it is output to the oscillator 18. balanced modulation with the output signal of The output signal of the balance w4 converter 17 is supplied to the balance modulator 9 through the BPF 19 as a conversion signal at a frequency corresponding to the jitter (fs→-40fH) or a frequency very close to this, and is then connected to the LPF 27, the switch circuit 7 and the ACC. Balanced modulation (frequency conversion) is performed with the reproduced low-frequency converted carrier color signal having jitter, which is sequentially passed through the circuit 8.

As a result, the reproduced carrier color signal returned to the original phase in the original band is extracted from the balanced modulator 9 through the BPF 33, and then passed through the comb filter 34 for canceling crosstalk from adjacent tracks. The signal is supplied to the burst extraction circuit 35 and also to the adder 31, where it is multiplexed with the reproduced luminance signal to form a reproduced composite color video signal and output to the output terminal 36.

Problems to be Solved by the Invention In the conventional video signal recording and reproducing apparatus having the above configuration, Y/
As the C separation circuit 2, a circuit having the configuration shown in FIG. 4(A) or (B) was used. The poly Y/C separation circuit shown in FIG. 4 (A) is a circuit that separates the luminance signal from the input composite color video signal using the LPF 40 to separate P waves, and separates and outputs the carrier color signal using the BPF 41. It is not possible to separate and output the high-frequency components of the luminance signals that occupy the same band, and the low-frequency components of the carrier color signal may remain in the output luminance signal of the LPF 40 and be slightly output due to color boundaries, etc. This caused deterioration in image quality.

On the other hand, the Y/C separation circuit shown in FIG.
The carrier color signal is passed through a comb-shaped filter consisting of a subtractor 44 and a subtractor 44 into 1 IliP waves, and is outputted to an output terminal 48 through a BPF 45, while being passed through a level W rectifier 46 to an input composite color video signal and a subtracter 47. The configuration is such that the luminance signal is subtracted, separated into p-waves, and outputted to an output terminal 49.

However, this Y/C separation circuit has a one-day delay line of 43.
'r+
-+/2 (however, f'H is the horizontal scanning frequency) and only frequency components in the vicinity are extracted, so in the case of a composite color video signal with vertical correlation to the image pattern, the transport Although the high-frequency component of the luminance signal that occupies the same band as the color signal can also be generated as a P wave, it is not possible to accurately separate Y/C for composite color video signals related to patterns with low vertical correlation, which deteriorates the image quality. There was a problem with letting it work.

Furthermore, the reproduced composite color video signal outputted from the output driver 36 is also multiplexed with a luminance signal and a carrier color signal, respectively.
Because it was a so-called composite signal, when this reproduced composite color video signal is to be displayed on a monitor on a display device or to be dubbed and recorded on another VTR, it is necessary to perform Y/C separation again in these devices. Therefore, the above-mentioned problem occurred.

In this way, conventionally, both the composite color video signal input to the input terminal 1 and the reproduced composite color video signal output from the output terminal 36 were composite signals.
Even if a comb filter is used, dot interference with the luminance signal caused by the color signal and cross-color interference with the color signal caused by the AT degree signal are unavoidable, resulting in deterioration of image quality, especially on large screens that have become popular recently. monitor television receiver,
However, there was a problem in that the image quality was noticeably degraded.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a video signal recording device and a recording/reproducing device that solve the above problems by recording and reproducing luminance signals and carrier color signals without multiplexing them.

Means for Solving the Problems The video signal recording device according to the present invention has a first
and a second input terminal dedicated to the carrier color signal, means for separately generating a frequency modulated at degree multiplied signal and a low-pass converted carrier color signal, and a means for frequency-dividing both of the generated signals. It consists of a means for multiplexing and recording.

Further, the video signal recording and reproducing device according to claim 2 is a device in which a reproducing system is further added to the above-mentioned recording device,
It further includes a first output terminal dedicated to the reproduced luminance signal and a second output terminal exclusively used to the reproduced carrier color signal, and outputs the frequency modulated luminance signal and the low-pass converted carrier color signal from the reproduced frequency division multiplexed signal into 1 iv 5-wave molecules, respectively. demodulating means for obtaining a reproduced luminance signal; frequency converting means for obtaining a reproduced carrier color signal;
The apparatus includes an output means for separately outputting a reproduced luminance signal and a reproduced carrier color signal from first and second output terminals.

Furthermore, the video signal recording and reproducing apparatus according to claim 3 of the present invention provides a luminance signal and two types of color difference signals, three primary color signals and a periodic signal, a tli degree signal and a carrier color signal.
means for separately generating a frequency-modulated luminance signal and a low-pass converted carrier color signal, each having an input terminal into which at least one set of signals separately enters; and frequency-division multiplexing of both of the generated signals. means for separating and recording a frequency modulated luminance signal and a low frequency converted carrier color signal from the reproduced frequency division multiplexed signal, respectively, demodulating means for obtaining a reproduced luminance signal, and means for obtaining a reproduced carrier color signal. frequency conversion means;
One or both of three types of primary color signals and two types of color difference signals are demodulated from the reproduced carrier color signal and the reproduced luminance signal, and three types of signals from these signals and the reproduced luminance signal are output at least at ~b ratio. There are more ways to do this.

The luminance signal and the carrier chrominance signal input separately to the one set of input terminals are generated into the frequency-modulated luminance signal and the low-pass converted carrier chrominance signal, and then frequency-division multiplexed by the recording means. recorded on the recording medium. Therefore, in the recording system, the input signal is converted into the frequency division multiplexed signal and recorded without passing through the Y/C branch circuit at all.

On the other hand, the reproduction system smell blade is configured such that among the reproduced frequency-modulated 111 m degree signal and the reproduced low-pass converted carrier color signal which are reproduced from the recording medium and separated, the reproduced frequency-modulated luminance signal is demodulated by the demodulating means. This becomes the reproduced luminance signal. Also,
The reproduced low-band converted carrier color signal is returned to the reproduced carrier color signal of the original band by the frequency conversion means. These reproduced luminance signals and reproduced carrier color signals are respectively supplied to the output means and outputted separately from the first and ff12 output terminals, or one of the three types of primary color signals and the two types of color difference signals. -or both primary color signals after being converted.

At least three types of signals are output from among the color difference signal and the reproduced luminance signal.

Therefore, even in the reproduction system, a reproduction signal is output in a form such as a component signal without generating and outputting a multiplexed signal (composite signal) of a luminance signal and a carrier color signal.

Example Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a block diagram of an embodiment of the present invention. In the figure, the same components as those in FIG. 3 are designated by the same reference numerals, and their explanations will be omitted. In FIG. 1, the ti degree signal Y and color difference signals (R-Y) and (B-Y) are input separately to the first set of input terminals 51-1, 51-2 and 51-3. In addition, a second set of input terminals 52-1.52-2.52-3
A red signal R1, a green signal G, a blue signal B, and a periodic signal are input separately to the input signal R1 and 52-4. Further, a luminance signal Y and a carrier color signal C are input separately to the third set of input terminals 53-1 and 53-2 in a separated state. That is, 5
3-1 is an input terminal exclusively for the luminance signal, and 53-2 is an input terminal exclusively for the carrier color signal.

The matrix circuit 54 generates a luminance signal Y and two types of color difference signals (R-Y
) and (BY), respectively. Switch circuit 55-
1 is the luminance signal from the matrix circuit 54 and the input terminal 51
One of the luminance signals from -1 is selectively output to the switch circuit 56.

Further, the switch circuit 55-2 supplies one of the color difference signal Q (RY) from the matrix circuit 54 and the color difference signal (R-Y) from the input terminal 51-2 to the balance W4 unit 58.

The switch circuit 55-3 receives the color difference signal (B-Y) from the matrix circuit 54 and the color difference signal (B-Y) from the input terminal 51-3.
-Y) is selectively output to the balanced modulator 59.

On the other hand, a color signal extracted from the oscillation 418 and having a frequency equal to the xm transmission frequency fS is phase-adjusted by a phase adjuster 62 to produce a frequency t's that has a predetermined phase and a phase difference of about 90°. After being converted into two types of signals,
They are fed separately as carrier waves to balanced modulators 5 and 59. From this, balanced modulated waves obtained by balanced modulating the carrier frequency rs with the color difference signals (R-Y) and (B-Y) are taken out from the balanced modulators 58 and 59, respectively, and the adder 6
0. As a result, the adder 60 outputs the carrier color signal obtained by quadrature two-phase modulation of the carrier frequency t's using the color difference signals (R-Y) and (B-Y) as the output signal of the encoder 61, and switches the switch. The signal is supplied to circuit 57.

The switch circuit 57 selects one of the carrier color signals generated by the encoder 61 and each carrier color signal from the Y/C separation circuit 2 and the carrier color signal dedicated input terminal 53-2. When outputting and recording, switch circuit 7
．． The signal is sequentially passed through an ACC circuit 8 and supplied to a balanced modulator 9.

Further, the switch circuit 56 is connected to the Y/-C separation circuit 2. One of the three types of brightness signals from the m-degree signal dedicated input terminal 53-1 and the switch circuit 55-1 is selectively outputted to the emphasis circuit 3. Normally, switch circuits 56 and 57 are switched in conjunction, and switch circuit 55
-1 to 55-3 are also switched in conjunction.

The low frequency conversion carrier color signal obtained by balanced modulation by the balanced modulator 9 and the FM luminance signal taken out from the HPF 5 are as follows.
After frequency division multiplexing by the adder 6 as in the conventional case,
The information is recorded on the magnetic tape 23 by the head 22 .

This allows, for example, a VTR that outputs a reproduced luminance signal and a reproduced carrier color signal without converting it into a composite signal during reproduction.
By inputting the output signals to the input terminals 53-1 and 53-2, respectively, dubbing recording can be performed on the magnetic tape 23 as a frequency division multiplexed signal of a predetermined standard without converting it into a composite signal. In this case, dubbing recording of good image quality can be performed without deterioration in image quality due to the Y/C separation described above.

Moreover, input terminals 51-1 to 51-3. or 52-1 to 5
2-4, by supplying a predetermined signal from a television camera, telecine, etc., it is possible to convert it into the predetermined frequency division multiplexed signal and record it on the magnetic tape 23 without converting it into a composite signal. Therefore, recording of good image quality can be performed without deterioration in image quality due to the Y/C separation described above. Furthermore, the frequency division multiplexed signal recorded by this recording system can also be compatiblely reproduced by an existing VTR using the low frequency conversion color recording and reproduction method.

Next, to explain the operation during reproduction, the reproduced carrier color signal which has been subjected to the same signal processing as in the conventional system and taken out from the comb filter 34 is transferred to the R-"Y demodulation circuit 63 and the B-'
The signals are supplied to the l-adjustment circuit 64, respectively.

On the other hand, as described above, the oscillator 18 outputs a signal for generating a frequency conversion signal for returning the reproduced low frequency converted carrier color signal to the reproduced carrier color signal of the original band. The signal frequency is a frequency equal to the color subcarrier frequency ts.

Therefore, in this embodiment, the output signal of this oscillator 18 is branched and supplied to the phase adjuster 62, where the R-Y axis, B
- Perform the necessary phase adjustment to perform demodulation on the Y axis,
Two output signals having a phase difference of 90 degrees from the phase adjuster 62 are separately supplied to the RY demodulation circuit 63 and the BY demodulation circuit 64 as demodulation reference carrier waves.

As a result, the demodulated baseband color difference signal RY is taken out from the RY demodulation circuit 63, and the similarly demodulated baseband color difference signal @B-Y is taken out from the B-YIA modulation circuit 64. It will be done. These color difference signals (R-Y)
and (B-Y) are respectively supplied to the matrix circuit 65 and output to output terminals 67-2 and 67-3.

The matrix circuit 65 uses the above two types of color difference signals and 7412
The reproduced luminance signals from the 7722 circuit 30 are respectively supplied, and these are subjected to known matrix processing to generate three primary color signals of a red signal (R), a green signal (G), and a blue signal (B), and the output terminals 68 -1.68-2 and 68-3
and a composite periodic signal (SYNC) to output terminal 6-4.

Some recent television receivers are equipped with video input terminals for three primary color signals, and others are equipped with video input terminals for color difference signals and luminance signals. etc., it is possible to display a high-quality color image. That is,
The reproduced video signal is converted into three primary color signals or T without being combined.
Since the fJ intensity signal and the two types of color difference signals are transmitted separately and simultaneously in a component signal format, there is no mutual interference caused by the combination of the luminance signal and the carrier color signal as in the prior art.

Further, the reproduced luminance signal taken out from the de-emphasis circuit 30 is output from output terminals 66-1 and 66-1 exclusively for reproduced luminance signals.
7-1. The reproduced carrier color signal from the comb filter 34 is output to an output terminal 66-2 exclusively for reproduced carrier color signals.
is also output. The reproduced luminance signal and the reproduced carrier color signal taken out from the output terminals 66-1 and 66-2 are output to be recorded by dubbing on another VTR, for example.

Incidentally, dubbing recording may be performed using the input signals of the input terminals 67-1 to 67-3 or the input signals of the input terminals 68-1 to 68-4, and since they are not converted into component signals even once, they are not converted into component signals. Image quality dubbing recording is possible, but the input terminal 53-1 is dedicated to luminance signals. By providing the dedicated input terminal 532 for the II sending white color signal, there is no possibility of color change due to errors in the encoder 61, the matrix circuit vR54, or even the matrix circuit 65, and dubbing recording with more faithful color reproducibility can be performed.

Incidentally, in the above embodiment, the encoder 61 generates the carrier color signal of the standard color television system from the three primary color signals or the two types of color difference signals.
Since the signal to be recorded is a low-band converted carrier color signal, this low-band converted carrier color signal may be directly generated.

This has been achieved in the second embodiment of the present invention shown in FIG.

In the figure, the same components as in FIG. 1 are denoted by the same reference numerals, and their explanations will be omitted. In FIG. 2, during recording, the PS processing circuit 16 outputs the same frequency as the color subcarrier frequency of the low-pass conversion carrier color signal (for example, 40·fn), and the phase moves in a fixed direction by 90° every horizontal scan Ill lff1. A signal is extracted in which the phase transition direction is inverted every field.

Therefore, in this embodiment, the output signal of this PS processing circuit 16 is supplied to a phase adjuster 69, where the output signal of 21! has a phase difference of 90 degrees from each other at the same time. The phase is adjusted to obtain a similar signal. Two types of signals extracted from the phase adjuster 69 and having a frequency of 40.1 days and having phases different by 90° at the same time are supplied to balanced modulators 58 and 59 as carrier waves, respectively. As a result, the adder 60
From the carrier wave 40 is the color difference signal (R-Y) and (B-Y).
- A low-pass conversion carrier color signal obtained by quadrature two-phase modulation of fn is extracted, and after removal of high frequency components by an LPF 70, it is supplied to an adder 6.

Note that the circuit that directly generates a low-frequency conversion carrier color signal from two types of color difference signals is not limited to the above-mentioned embodiment; for example, the circuit proposed by the inventor in Japanese Patent Application No. 33330/1982 Processing circuits can also be applied. This proposed processing circuit consists of four types of 40 f
A total of two H low-frequency carrier waves are selected and outputted every horizontal scan II, and are respectively supplied to two balanced modulators to which two types of color difference signals are supplied.

Further, the present invention is not limited to the VTR of the above-described embodiment, but can also be applied to other video signal recording and reproducing apparatuses that use an optical disc or a magnetic disc capable of recording and reproducing as a recording medium.

Furthermore, the PS processing is performed using the well-known P l (Phase Inv
Further, in the case of a recording/reproducing method other than the azimuth recording/reproducing method, this processing is not necessary.

Effects of the Invention As described above, according to the present invention, the Kimaro TG signal and the carrier color signal are band-sharing multiplexed based on the input signals (luminance signal, carrier color signal, primary color signal, color difference signal, etc.). Since a predetermined frequency division multiplexed signal is generated and recorded without ever separating it from the composite signal, Y/C
Signal deterioration due to separation can be completely eliminated, and signals with good image quality can be recorded and dubbed.In addition, if input terminals dedicated to luminance signals and input terminals dedicated to carrier color signals are provided, three primary color signals and Since there is no need for an encoder or matrix circuit to generate luminance signals and carrier color signals from color difference signals, it can be constructed at an extremely low cost by simply improving the current VTR, and there is no possibility of color changes due to errors in the matrix circuit. This makes it possible to record with greater fidelity in terms of color reproducibility, and in addition, it is possible to effectively use the entire luminance signal band, including the luminance signal high-frequency components of the carrier color signal band, which were previously removed. , it is possible to achieve even higher image quality. In addition, since the luminance signal, color difference signal, primary color signal, or carrier color signal are output separately without Y/C separation, signal deterioration due to Y/C separation and mutual interference due to the combination of the three signals may occur. Also, there is no interference such as cross color or dot interference caused by incomplete Y/C separation, so it is especially suitable for television reception on large screen monitors. xIta also has the advantage of being able to reproduce and display high-quality color images with no noticeable deterioration in image quality.
