Abstract

PURPOSE:To reduce the deterioration in the quality of video signals remarkably, by eliminating the sound signal only at the 1st and 2nd band rejection filters from a reproduced output obtained from the 1st and 2nd tracks. CONSTITUTION:The signal component only of the sound signal in the 1st track is eliminated at the 1st band rejection filter 71A from a reproduced output SA obtained from the 1st track and the signal component only of the band of the sound signal in the track is eliminated at the 1nd band rejection filter 71B from a reproduced output SB obtained from the 2nd track.

Description

Detailed Description of the Invention The present invention provides a method for reproducing video signals and audio signals from a magnetic recording medium in which video signals and audio signals constituting a television signal are recorded with high density on the same magnetic track. In particular, the present invention relates to an audio signal reproducing device in which omission of information in a video signal can be minimized and deterioration in quality of the video signal can be significantly reduced.

When recording video and audio signals on magnetic tape, the usual recording method involves recording a video signal that is a mixture of a frequency-modulated luminance signal on the high frequency side and a frequency-converted carrier chrominance signal on the low frequency side using a rotating magnetic tape. A head records on a video track inclined with respect to the tape running direction, and a frequency-modulated audio signal is recorded on an audio track extending in the tape running direction on one side of the tape using a fixed magnetic head. If the audio signal is 2 channels, such as a stereo audio signal,
The audio signal of the λ channel is recorded on separate parallel audio tracks by a separate fixed head.

In this type of recording method, the running speed of the magnetic tape is slowed down so that the video signal is transmitted at high density so that adjacent video tracks are adjacent to each other, without forming so-called guard bands between adjacent video tracks. If you record, you can record for a long time.

However, in this case, crosstalk between adjacent video tracks during playback becomes a problem, but video signals are recorded alternately on every seven tracks using two rotating heads with different azimuth angles, and If that track is played back using a rotating head with the same azimuth angle as when it was recorded, the azimuth loss for the crosstalk component from the adjacent track will be large for the brightness signal frequency-modulated on the high frequency side. The problem will be solved.

Furthermore, although the effect of azimuth loss cannot be expected for the carrier color signal whose frequency has been converted to the lower frequency side, the phase should be made continuous on every other track, and/or on every other track. By recording in a controlled state such as inverting each horizontal period, and passing the reproduced carrier color signal restored based on its phase through a comb-shaped characteristic filter, crosstalk components from adjacent tracks can be eliminated. can be removed.

By the way, when recording video signals at high density by slowing down the running speed of the magnetic tape, the relative speed between the rotating head and the tape can be maintained at a speed sufficient to record video signals, but it is difficult to record audio signals. This has the disadvantage that the relative speed between the fixed head and the tape decreases, and the quality of the recorded audio signal deteriorates. Therefore, it is possible to avoid deterioration in the quality of the audio signal by mixing the audio signal with the video signal and recording the mixture using a rotating head on a track that is inclined with respect to the running direction of the tape. In this case, the video signal, in which the frequency-modulated luminance signal and the low frequency-converted carrier color signal are mixed, is further mixed with two channels of audio signals and recorded at high density on the same track. In order to do this, it is necessary to ensure that there is no crosstalk interference between adjacent tracks with respect to the reproduced audio signal, and also to be able to separate and extract each signal, especially the audio signals of two channels, at the time of reproduction.

Therefore, a method can be considered in which the frequency relationships of each signal are set to the relationships shown in FIGS. 1 and 2 and recorded. 1st
In the figure and FIG. 2, the horizontal axis shows the frequency f, and the vertical axis shows the level t. That is, this method, as shown in FIG.
A relatively narrow frequency band B3 from the upper limit of the band of the low-pass-converted carrier color signal CL to the lower limit of the band of the frequency-modulated luminance signal YF is defined as the audio signal band, and this band Bs is defined as the same width q. The frequency is divided into two bands, and the first to ≠-th frequencies f, -f4t are set as the center frequency of each band. However, fi < f, z < f 3 < f
It is 4z. The l-channel audio signals are each frequency-modulated, but in this case, in every other first track TA shown in FIG. f, and f3, and in every other second track TB, the l-channel audio signal is modulated using other non-adjacent second and ≠ frequencies f, 2 and f. frequency modulation. That is, when the l-channel audio signal is a left signal and a right signal of a stereo audio signal, for example, as shown in FIG. 2, the first track TA has a frequency-modulated left signal LA with a carrier frequency of f. The frequency-modulated right signal RA with a carrier frequency of f3 is recorded, and the !th! On the track TB, a frequency-modulated left signal LB with a carrier frequency f- and a frequency-modulated right signal RB with a carrier frequency fII are recorded.

Set the white beak to 3.2MHz. In addition, in this case, the level of the carrier color signal CL is made lower than the level of the luminance signal YF, and the audio signal LA + LB + R

The left signal LIA and the left signal RA recorded on the first track TA are separated and taken out by the third band pass filter, and the left signal LIA and the left signal RA recorded on the first track TA are separated and taken out.

The frequency is demodulated by the ≠ frequency demodulation circuit, the continuous reproduced left signal is obtained by the output of the first and second frequency demodulation circuits, and the continuous reproduced right signal is obtained by the output of the third and ≠ frequency demodulation circuit. . Also, from the first and second tracks TA and TB, the first

RA r RB is removed, and the playback output from which the audio signal has been removed is supplied to a video signal playback system to obtain a continuous playback video signal.

According to the method or apparatus described above, in each of the first and second tracks TA and TB, two channels of audio signals, for example, a left signal and a right signal of a stereo audio signal, are
Using non-adjacent λ frequencies of ~≠th frequency f/~f, i.e., for example, two frequencies 300 kHz apart
Since frequency modulation is performed using two frequencies, the two bandpass filters that separate and extract the frequency-modulated left and right signals from the playback output obtained from the same track and the same rotating head have very poor passband characteristics. The output of each bandpass filter does not have to be steep (this makes the design of the bandpass filter easier). , signals with adjacent carrier frequencies mix in as crosstalk components from adjacent tracks, and a beat occurs between this crosstalk component and the main signal, resulting in a beat in the output of each frequency demodulation circuit. It is conceivable that noise may appear, but in the above method, the first to
For example, the interval between two adjacent frequencies of frequencies f, -f, , is /,! ;OkHz, which is outside the band of the demodulated Otoyama signal, so these beat noises can be removed by providing a low-pass filter on the output side of each frequency demodulation circuit.

However, in the above-mentioned method or apparatus, since the audio signals of the channels recorded on the same track are frequency-modulated using two non-adjacent frequencies among the seventh to ≠ frequencies f/ to f, As is clear from FIG. 2, the frequency band of the audio signal on the same track ends up being widened, such as BX in the first track TA and BY in the second track TB. Therefore, in order to prevent the frequency-modulated audio signal from interfering with the video signal on the playback side, it is necessary to It is necessary to remove the Bs signal component, and as a result, information in the video signal is often omitted in the high frequency region of the low frequency-converted carrier color signal Ct and the low frequency region of the frequency modulated luminance signal YF. There is an inconvenience that the quality of the fault signal deteriorates considerably.

However, the level of frequency-modulated audio signals as crosstalk components from adjacent tracks mixed into the playback output is low due to playback azimuth loss, and there is little risk of interfering with the video signal. From the reproduced output, a signal component in the band Bx shown in FIG. 2 is removed by a first band elimination filter, and from the reproduced output of the second rotary head, a signal component in the band Bx shown in FIG. It is also possible to remove the signal component of the BY signal. According to this, as shown by the chain line in FIG. For the second track TH, the component of the carrier color signal CL converted to the low frequency band can be extended to the high frequency side and extracted, and the omission of information in the video signal can be somewhat reduced. (It is possible. However, there are still many missing information in the video signal.)
The quality of the video signal deteriorates considerably.

In view of the above-mentioned points, the present invention, in combination with a special recording method, minimizes the omission of information in the video signal and significantly reduces the deterioration in the quality of the video signal.

In the recording method that is the premise of the present invention, the frequency relationship of each signal is set as shown in FIGS. In Figures 1 and 5, the horizontal axis represents the frequency f, and the vertical axis represents the level t. That is, as shown in Figure ≠, the relatively narrow frequency band BS between the low-pass converted carrier color signal C+ and the frequency-modulated luminance signal YF is the audio signal band, and this band B8 is the same width. is divided into t bands, and the first to third frequencies f/~ are set as the center frequency of each band.
The point of setting f≠ is the same as the above method, but in this method, in the first track TA, the audio signal of the λ channel is divided into the adjacent first and second frequencies f/ and f.
, 2, and in the second track TB! The audio signal of the channel is frequency modulated using different adjacent third and ≠ third frequencies f3 and f. That is, when the audio signals of two channels are the left and right signals of a stereo audio signal, for example, as shown in FIG. A frequency-modulated right signal RA with a carrier frequency f, 2 is recorded, and a frequency-modulated left signal L13 with a carrier frequency f3 and a frequency-modulated right signal L13 with a carrier frequency f, are recorded on the second track TB.

This carrier color signal CO is then supplied to a comb-shaped characteristic filter K through a bandpass filter g7 to remove crosstalk components from adjacent tracks, and the carrier color signal Co from which the crosstalk family and tray have been removed is obtained. The carrier color signal is led out to the output terminal 2.

In the recording method that is the premise of the present invention, when recording video signals and audio signals at high density on the same magnetic track, a comparison between a low-frequency converted carrier color signal CL and a frequency-modulated luminance signal YFO is required. The narrow frequency band B8 is set as the audio signal band, and within this band B, the seventh to ≠ frequencies f/~f are set, and the audio signals of two channels are distributed between every other track TA and the other one. When performing frequency modulation using these first to WJ≠ frequencies f, -f, divided by two tracks TB, the λ channel audio signal is modulated by these first to WJ≠ frequencies in each track TA and TH. Frequency modulation is performed using two adjacent frequencies f7 to f, and in the playback device of the present invention, the first and second bands are determined from the playback output obtained from each track TA and TB. Removal filters 7/A and 7/
Since the reproduced video signal is obtained by removing only the two frequency-modulated audio signals whose carrier frequencies recorded on each track are adjacent to each other, the audio signal of the !channel is mixed with the video signal. It is possible to minimize the omission of information in the video signal due to the recording, and it is possible to significantly reduce the deterioration in the quality of the video signal.
