FIG. 4 is a block diagram for explaining an embodiment of the signal recording device, and FIG. 4 is a conceptual diagram for explaining a screen during reproduction. Embodiments will be described below with reference to the drawings. Hereinafter, the recording system and the reproducing system will be described separately.

The outline of the present embodiment is as follows. The recorded combined video signal ab obtained by combining the first and second input video signals aa and bb by the combining means A is recorded on the magnetic tape by one recording system, The reproducing composite video signal obtained by reproducing from this magnetic tape is divided by the dividing means D.

To explain the recording system with reference to FIG. 1, the first and second input video signals aa and bb are transmitted from a transmission line (not shown) to synthesize the composing means A, which will be described later, and the input terminal a of the first selecting means SW1. , C and the input terminals d and f of the fourth selecting means SW4, respectively. Further, the recorded combined video signal ab output from the combining means A is the input terminal b of the first selecting means SW1.
And the input terminal e of the fourth selecting means SW4.

The first and second input voice signals cc and d
d corresponds to the first and second input video signals aa and bb, respectively, and the first input audio signal cc is the second selection means SW.
It is supplied to the two input terminals a and b, the input terminal a of the third selecting means SW3, the input terminals g and h of the fifth selecting means SW5, and the input terminal g of the sixth selecting means.

On the other hand, the second input audio signal dd has the input terminal c of the second selecting means SW2, the input terminals b and c of the third selecting means SW3, the input terminal i of the fifth selecting means SW5, and the sixth terminal. Is supplied to the input terminals h and i of the selection means.

Here, the first selecting means SW1 plays a role of selecting an image to be recorded, and the second and third selecting means SW2 and SW3 respectively play a role of selecting an audio to be recorded, and the fourth selecting means S.
W4 plays a role of selecting an image to be output to a TV, the fifth selecting means SW5 plays a role of selecting a main sound to be output to a TV or the like, and the sixth selecting means 6 plays a role of selecting a sub sound to be output to an earphone or the like. The selection operation of the first to sixth selection means SW1 to SW6 will be described with reference to Table 1 below. In Table 1, "1" means the first input video signal aa or the first input audio signal cc, and "2" means the second input video signal bb or the second input audio signal dd. To do.

[0021]

[Table 1] The first to third selection means SW1 to SW3 are controlled by the control signal supplied from the recording selection means B1 in the input means B operated by the operator, and the fourth selection means SW4 is the monitor image selection means. The fifth and sixth selecting means SW5, 6 are controlled by the control signal supplied by the monitor sound selecting means B2 by the control signal supplied by B3. However, the combinations marked with “X” in Table 1 have no meaning for the operator, and cannot be selected by the input means B. For example, when the first input video signal aa is recorded and the signal aa is output to the TV, it is not necessary to monitor and output the second input audio signal dd. The sixth selecting means SW5, 6 are configured to select only the input terminal g and output the first input audio signal cc.

To explain the signals to be recorded during the two program recording, first to third selecting means SW1 to SW3 are described.
Selects the input terminal b. First, as for the video signal, the recording / synthesized video signal ab is supplied to the video recording means 1.
The video recording means 1 performs YC separation of the recorded composite video signal ab which is the output signal of the first selection means SW1 into a luminance signal and a carrier color signal by using a comb filter or the like, performs pre-emphasis on the luminance signal, and performs overmodulation. After passing through a limiter that limits the amplitude to prevent the inversion phenomenon that occurs, FM modulation is performed to generate a frequency-modulated luminance signal. On the other hand, the carrier color signal is converted into the low frequency band and the low frequency band conversion color signal is generated by performing a PS process for shifting the phase by 90 ° for each line in order to prevent crosstalk between adjacent tracks. Then, the frequency-modulated luminance signal having a relatively high frequency component and the low frequency conversion color signal having a relatively low frequency component are frequency division multiplexed to generate an output signal. Then, this output signal is recorded on the magnetic tape TT by using the magnetic heads H1 and H2 which are provided on the rotating drum (not shown) and are separated by 180 °. The video recording means 1 operates similarly when the input signals are the first and second input video signals aa and bb, whereby the simultaneous recording of a plurality of video signals and the normal video signal are performed. The video signal recording means 1 is also used in the case of recording.

Next, the audio signal will be described. The first input audio signal cc is supplied to the first audio recording means 2 via the second selecting means SW2. The first audio recording means 2 performs noise reduction processing such as pre-emphasis on the first input audio signal cc, and then FM-modulates the output signal obtained through FM modulation to the magnetic tape TT. It is recorded in. Here, the magnetic heads H3 and H4 are mounted on the rotary drum so as to be separated by 180 ° and to precede the magnetic heads H1 and H2 by reverse azimuth, and an FM-modulated audio signal is recorded in the deep portion of the magnetic tape TT. Then, the FM modulated video signal is recorded on the surface layer portion by using the magnetic heads H1 and H2. In addition, even when the output signal of the second selecting means SW2 is the second input audio signal dd, the first
The voice recording means 2 operates similarly. Further, the first audio recording means 2 may have two systems of FM modulation systems having two different carrier frequencies, and output signals thereof may be frequency-multiplexed to support stereo recording.

On the other hand, the second audio signal dd is supplied to the second audio signal recording means 3 via the third selecting means SW3, where it is subjected to noise reduction processing such as pre-emphasis and then the bias signal is applied. The superimposed audio signal is recorded on the audio track formed in the longitudinal direction of the magnetic tape TT via the magnetic head H5. Incidentally, the third selecting means SW
The second audio recording means 3 operates similarly when the output signal of 3 is the first input audio signal cc.

In this way, the recorded combined video signal ab obtained by combining the first and second input video signals aa and bb and the first and second input audio signals cc and dd can be simultaneously recorded. it can.

The signals to be monitored when two programs are recorded will be described. First, for the video signal, the fourth selection means SW4 selects the input terminals d to f to obtain the monitor video signal ee.

That is, as shown in Table 1, the fourth selection means SW
When the input terminal d is selected in step 4, the first input video signal aa is output to the TV monitor (not shown), and the fifth and sixth selection means select the input terminal g to select the first input video signal aa. The input audio signal cc is the main audio signal ff and the sub audio signal g
It is output as g to the TV monitor and earphone not shown. Here, the fifth and sixth selection means SW2 and SW3 make the input terminals h and i unselectable, and the monitor image selection means B3
The monitor audio selecting means B2 generates the control signal so as to select only the input terminal g on the basis of the control signal outputted from the first input video signal aa as the monitor video signal ee. This is to prevent the operator from thinking that the second input audio signal dd is a malfunction of the device and to improve the usability.

Similarly, when the input terminal f is selected by the fourth selecting means SW4, the second input video signal bb is output to the TV monitor (not shown) and the fifth and sixth selecting means are provided. Selects the input terminal i and outputs the second input audio signal dd as a main audio signal ff and a sub audio signal gg to a TV monitor and an earphone not shown respectively.

On the other hand, the input terminal e in the fourth selecting means SW4
When is selected, the recorded composite video signal ab is not shown in T
The screen is output to the V monitor, and the screen becomes a so-called letterbox screen in which two screens are arranged in parallel as shown on the right side of FIG. In such a case, the first and second input video signals aa,
Since bb is simultaneously displayed on the TV monitor, it is necessary that the main audio signal ff and the sub audio signal gg can be both the first and second input audio signals cc and dd. Therefore,
As shown in Table 1, the fifth and sixth selection means SW5 and SW6 can select any of the input terminals g, h and i.

Now, here, the first and second input video signals a
The synthesizing means A for synthesizing a and bb will be described in detail. As shown in FIG. 1, the main part of the synthesizing means A is composed of a memory A2, a memory control means A1 and the like. Based on a control signal output from the memory control means A1,
The second input video signals aa and bb are selectively stored in the memory A2, read out in a predetermined order, and recorded and composited video signal ab
Is being generated.

This combining process will be described with reference to FIG. Screens a and b in the figure are screens of the first and second fields related to the first input video signal aa, and screens c and d are first and second screens related to the second input video signal bb. It is a screen of the field. Then, the memory A2 stores one of the fields and does not store the screen related to the other field. Here, only the screen of the first field is stored, and the memory A stores the screen of the first field relating to the first input video signal aa and the screen of the first field relating to the second input video signal bb. Is stored.

The screen E and the screen F are divided into a screen T composed of an odd line shown by a solid line in the figure, and a screen J composed of an even line shown by a dotted line, respectively. A screen field of the first field relating to the recording composite signal ab is generated by combining screen fields composed of odd lines,
The screens C and N composed of even lines are combined to generate the screen of the second field related to the recording combined signal ab.

Specifically, the first line relating to the first input video signal aa → the first line relating to the second input video signal bb → the third line relating to the first input video signal aa → the second line The third line of the input video signal bb → the second N + 1 line (where N is an integer of 0 or more) of the first input video signal aa → the second N + 1 line of the second input video signal bb,
The first field of the recorded composite video signal ab is generated by reading the signal from the memory A in the order of, and the second field is generated by similarly reading the signal of the even line. At the time of this composition, pixels in the horizontal direction may be thinned out every other pixel, or pixels in the horizontal direction may be thinned out by taking an average value of adjacent horizontal pixels.

Next, the reproducing system will be described with reference to FIG. The same components as those in FIG. 1 are designated by the same reference numerals and the description thereof will be omitted. In the figure, the signal reproduced from the magnetic tape TT by using the magnetic heads H1 and H2 is supplied to the video reproducing means 11 having a complementary relationship with the above-mentioned video recording means 1, and the reproduced signal is reproduced in the high frequency range. To obtain a frequency-modulated luminance signal reproduced separately into the low frequency band and a reproduced low frequency band converted color signal, and FM demodulation is applied to the former, followed by de-emphasis to generate a reproduction luminance signal. On the other hand, the latter is subjected to high frequency conversion and is subjected to a 90 ° phase shift opposite to that at the time of recording for each line to obtain a reproduction carrier color signal. Then, the reproduction luminance signal and the reproduction carrier color signal are added to generate the reproduction video signal 11a.

This reproduced video signal 11a is supplied to the memory D2 in the dividing means D and at the same time the seventh selecting means SW11.
Is supplied to the input terminal l of. Also, the seventh selection means SW
A reproduction division video signal is supplied to the input terminal k of 11 from the division means D, and the seventh selection means SW11 selects the input signal based on the second control signal C2 to generate the output video signal hh. .

Here, the memory D2 and the memory control means D1
The operation of the dividing means D constituted by and will be described with reference to FIG. When the reproduced video signal 11a is the reproduced signal relating to the recording / combined video signal ab shown on the right side of FIG. 4, the dividing means D operates effectively and selectively reproduces two screens as shown on the left side of FIG. It is a thing.

That is, the reproduced video signal 11a is stored in the memory D2.
The first and second field screens are temporarily stored. Then, based on the first control signal C1 representing the screen selection supplied from the control means C, the memory control means D1 causes the memory D2 to operate.
To control. For example, when reproducing the video 1 in FIG. 4 corresponding to the first input video signal aa, one screen is synthesized from the first and second field screens of the reproduced video signal 11a related to the video 1 and the first screen is displayed. A screen related to a field is generated, the screen related to the next field is the same screen as the first field, and one screen is generated from the third and fourth field screens in the next field, and the following is repeated to reproduce the split video. Generating a signal. In this way, although the reproduced divided video signal has one field thinned out, a complete signal can be obtained for one field, so that deterioration of vertical resolution can be prevented to a minimum regardless of recording / reproducing of two screens. . Of course, when generating the reproduction divided video signal, the expansion interpolation processing may be performed using the adjacent line or the adjacent pixel. Further, the memory D2 and the memory control means D1 are the memory A2 and the memory control means A1 used at the time of recording.
Of course, the structure may be simplified by using the two functions, and when the three-dimensional YC separation is used, the memory used for this and the memories A2 and D2 may be used.

Next, the reproduction of the audio signal will be described. The signal reproduced from the magnetic tape TT by using the magnetic heads H3 and H4 is supplied to the first audio reproducing means 12 having a complementary relationship with the first audio recording means 2, where FM demodulation and noise are performed. The output signal obtained by performing the reduction process is supplied to the input terminals m and n in the eighth selecting means SW12 and the input terminal m in the ninth selecting means SW13.
Further, the signal reproduced by using the magnetic head H5 is supplied to the second audio reproducing means 13 having a complementary relationship with the second audio recording means 3 and the output signal obtained by performing noise reduction processing or the like there. Are supplied to the input terminal o in the eighth selecting means SW12 and the input terminals n, o in the ninth selecting means SW13.

Then, the eighth and ninth selecting means 12, 13
Selects an input signal based on a third control signal C3 output from the control means C and selectively outputs a main output audio signal ii and a sub output audio signal jj to a TV monitor and earphone not shown. .

Here, the output video signal h when the magnetic tape TT on which the recorded composite video signal ab is recorded is reproduced.
The relationship between h, the main output audio signal ii, the sub output audio signal jj, and the first to third control signals C1 to C3 will be described with reference to Table 2 below. It should be noted that "1" and "2" in Table 2 mean reproduction of images 1 and 2 related to the first and second input image signals aa and bb.

[0041]

[Table 2] First, when displaying images 1 and 2 simultaneously in a letterbox format as shown in the image output image in Table 2,
Since it is not necessary to divide the reproduced video signal 11a, the first control signal C1 is turned off, and the second control signal C2 is input to the input terminal l of the seventh selection means SW11 so that the reproduced video signal 11a becomes the output video signal hh. It is controlled to select.
In this case, the third control signal C3 is the input terminal m of the eighth and ninth selecting means SW12 and SW13 so that the first and second input audio signals aa and bb can be selected. Any of o can be selected.

When the video 1 is output next, the first control signal C1 is in the video 1 selection mode and controls the dividing means D to output the reproduction divided video signal relating to the video 1, and the second control signal C1 is output.
The control signal C2 of is a reproduction division video signal and an output video signal hh
Therefore, the seventh selection means SW11 controls to select the input terminal k. Further, in such a case, if the signals output from the first audio reproducing means 12 corresponding to the video 1 are not output as the main audio output signal ii and the sub audio output signal jj, the video and the audio do not match, The third control signal C3 controls the eighth and ninth selecting means SW12 and SW13 so as to select the input terminal m.

Further, when outputting the video 2, the first control signal C1 goes into the video 2 selection mode, controls the dividing means D to output the reproduction divided video signal relating to the video 2, and outputs the second control signal. C2 is an output video signal h which is a reproduction division video signal
The seventh selecting means SW11 controls so as to select the input terminal k so as to set to h. Further, in such a case, if the signals output from the second audio reproducing means 13 corresponding to the video 2 are not output as the main audio output signal ii and the sub audio output signal jj, the video and the audio do not match each other. Third
Control signal C3 of 8th and 9th to select input terminal o.
It controls the selection means SW12 and SW13.

In this way, normal reproduction can be performed, and video and audio can be selectively reproduced from the magnetic tape on which two screens are simultaneously recorded.
