Description

The present invention relates to the field of consumer electronics and radio broadcasting, television and communications.

State of the art

An analogue of the invention: Kononovich L.M. System / method / two-channel stereo with polar modulation. / N.V. Gromov, T.D. Zalesov, B.K. Carro-Est. Reference book: Radios, radios, electrophones and tape recorders. Lenizdat, 1983

The set of features of analogues similar to the set of essential features of the invention:

1 - the mismatch of the points of the sound emitters on the screen / for example, television /, determined by the eyes of the listeners, and the points of the sound sources determined by the listeners with their hearing aid / binaural effect / in the viewing / listening room / stereo TV broadcasts, when the listener shakes his head / listener shifts / ;

2 - the effect of the difference in the course of sound waves from two sound emitters in the stereo broadcast receiver to the listener's left and right ears when determining the point of the sound emitter;

3 - imaginary heat of sound emitters in stereo; / for example, two valid sound emitters in two-channel stereo /;

4 - versatility stereo system;

5 - accuracy of determining the points of sound sources in stereo receivers;

6 - coverage area of the stereo effect in the listening room of the receiving devices;

7 - the combination of stereo with monophonic broadcasting;

8 - the identity of the stereo channels;

9 - creeping of signals of two or more channel stereo from one channel to another when dividing stereo channels;

10 - automatic adjustment of sound power with n sound emitters;

11 - the direction of the horns emitter of sound;

12 - interference phenomena from n sound emitters;

13 - mechanical movement of sound sources by electronic-mechanical robots;

14 - stereo effect quality;

15 - the number of applied sound sources in stereo receivers;

16 - broadband signal channels of stereo devices.

Reasons that impede the receipt of the required technical result in analogues, relative to the invention:

1 - the mismatch of the points of the sound emitters on the screen / for example, television /, determined by the eyes of the listeners, and the points of the sound sources determined by the listeners with their hearing aid / binaural effect / in the viewing / listening room / stereo TV broadcasts, when the listener shakes his head / listener shifts / .

The two-channel stereo modulation with polar modulation currently existing in Russia / author L.M. Kononovich / has a number of disadvantages. Some of them - random movement of the listener's head by Δ l≥ ± 1 cm - lead to the determination of n different points of the same emitter of audio signals, which is unacceptable when watching television broadcasts / there are no coincidences of the image points of the sound emitters on the screen and the points determined listeners of the same image points of sound signal sources with their hearing aid.

It should be noted that regardless of the design of the human brain / stereo signal analyzer: for example, conducting a study of the correlation function of the spectral amplitudes of signals at each frequency with different filter factors for different frequencies, the model of which creates additional dependencies / there is a phenomenon of comparison of two identical signals / definitely at least for one of the frequencies of the spectrum of the sound emitter / when the listener determines the direction of the sound sources. One distance from the listener's left and right ears to the sound source creates “compensation” between the ears when the listener's head rotates, at which the phase difference of the two signals from the two-channel stereo is reduced to zero.

For the experience of stereophonic transmission of sound signals in the present invention when playing a television recording of signals with stereo in accordance with the device of the present invention, we can recommend multimedia projectors: Canon LV-7525, Canon LV-7510, Hitachi CPS-960, which have sufficient brightness for a satisfactory television images on a projection screen with an area of 5-7 m ² or more. Behind the screen area, you can arrange the required number / N / of sound sources that create the effect of stereo.

Determine the required angle of rotation of the head of the listener / Fig. 1/ to determine the point of the sound emitter, in two-channel stereo when the head of the listener deviates from the central axis Oz by Δ x = 1-3 cm / Fig. 2/.

The distance from the television screen to the location of the ears of the head of the listener: h = 1-10 m.

The distance between the ears of the listener: l _goal. = 18 cm.

The distance between the sound emitters of the 1st and 2nd channels / Fig. 2/ or A and B / Fig. 4/: l = 3-5 m.

It should be noted that the mechanism created by nature for determining the point of the sound emitter on a television screen determines the coincidence at one point in the space of the vertices of two isosceles triangles, the sides of which come from two eyes and two ears of the listener. From the condition of the equality of the sides of the triangle, the equality of the times of propagation of sound energy from the point of the emitter to the left and right ears of the listener follows, which, provided that the amplitude-frequency characteristics in the left and right hearing aids of the listener coincide in time / and therefore, in amplitude /, perceive the definition of the point sound energy emitter:

This is true and sufficient under certain assumptions of the mathematical model in the calculations to determine the necessary angle of rotation of the listener's head to the point of the emitter of sound energy.

In figure 1:

a ₂ = b ₂ - isosceles condition of a triangle when the listener determines the point of sound emission / point A /;

a ₁ = b ₁ - equality valid for chords of equal arcs;

α ₁ α ₂ - additional angles up to 180 ° angles β and γ;

α is the angle of rotation of the head of the listener when determining the point of sound emission / point A /;

l _goal - the distance between the ears of the listener.

From Fig. 1 we determine the dependence of the value of the required angle of rotation of the listener's head / α / to determine point A - the point of sound emission from the value of the difference in distance from the left and right ears of the listener to point A in the initial state: α = φ / а-b /.

We obtain from the corresponding triangles:

From / 1 /:

Subtract the equality / 2 / from / 3 /:

We obtain the quadratic equation for the unknown distance a ₁ .

Find the roots of the quadratic equation / 4 /:

When: β = π -α ₁ ; γ = π -α ₂ ; h≥ 1-10 m; l _goal = 18 cm and angles α ₁ , α ₂ tending to 0 / zero /:

cosβ = cosα ₁ = 1;

cosα = cosα ₂ = 1.

With an approximate difference of a-b = 1-3 cm, we take: a ₂ = b; a = b in the sum of these terms.

We get: a ₂ cosβ + bcosγ = 2b.

From / 5 /:

Therefore, under the assumptions made, there is equality:

We take the value a ₁ = / 0.5-1 / · / ab /, which determines the difference in the signal path of the sound emitter from point A to the left and right ears of the listener based on the accuracy of the calculations.

We define from a triangle forming at one of its vertices the angle α / angle of rotation of the listener's head to the point of the sound emitter — point A /, the dependence of a ₁ on the above angle α:

We obtain when a ₁ = / 0.5-1 / · / ab /:

Thus, when

/ a-b / = 1 cm α = / 3-6 / °;

/ a-b / = 2 cm α = / 6-12 / °;

/ a-b / = 3 cm α = / 9-18 / °.

This is much more than the angle of 3 °, corresponding to the accuracy of determining the point of the emitter of sound signals by a person / see: Small Soviet Encyclopedia. T.I: Binaural effect.

Define from figure 3 the total angle:

α Σ = α _{source star} + α _video ,

corresponding to the discrepancy between the point of the sound source determined by the listener in two-channel stereo and the video point on the screen emitting the same sound signal when the head of the listener is displaced by Δ _x from the central axis (Fig. 2/).

When h = 1.5 m - the distance from the listener to the screen / or the location line of the speakers of the 1st and 2nd channels /;

l = 3 m - the distance between the speakers of the 1st and 2nd channels;

l _goal = 18 cm - the distance between the ears of the listener

and the displacement of the listener's head by Δ _x = 3 cm, corresponding to the difference in distances from the sound emitters of the 1st and 2nd channels to the left and right ears of the listener: a-b = 3.8 cm / Fig.2/, we obtain the corresponding angle α ₂ = α _{source star} = / 10-20 / ° / Fig. 3/.

For point α _video / α 1 / - point 0 / Fig. 3/ when the listener is shifted by Δ _x = 3 cm:

α _video = α 1 = 90 ° -arctg [h / Δ x] = 90 ° -89 ° = 1 °.

Thus, the total angle of rotation of the head of the listener relative to the video point / point 0 / and the point defined as the sound source / point A / - figure 3, when the listener is shifted by Δ _x = 3 cm is equal to:

α Σ = / 10-20 / ° + 1 ° = / 11-21 / °

The distance OA / 3 / corresponding to the angle α Σ = 11 ° is

OA = Δ _x + O ″ B,

OA = 3 + 26.3 = 29.3 cm.

Thus, the point of the video on the screen and the point of the imaginary sound emitter for the listener / viewer / do not coincide with each other in two-channel stereo when shifted by Δ _x , i.e. the listener experiences some inconvenience: he cannot hold various poses in the chair / in addition, displacements of the listener's head lead to ambiguous determination of the points of imaginary sound sources at different time points /, which is excluded in the present invention, where there are only real sound sources that are not dependent on displacements listener head at Δ _x .

2 - the effect of the difference in the course of sound waves from two sound emitters in the stereo broadcast receiver to the left and right ears of the listener when determining the point of the sound emitter.

Define the difference in the course of the two sound emitters / A, B / to the points / 1 / and / 5 / in two-channel stereo / 4 /:

Δ _{a, b} = b-a; Δ _cd = cd.

In figure 4:

a is the distance from the sound emitter A to the left ear of the listener / point 1 /,

b is the distance from the emitter of sound B to the right ear of the listener / point 5 /,

C is the distance from the sound emitter A to the right ear of the listener / point 5 /,

d is the distance from the emitter of sound B to the left ear of the listener / point 1 /,

ОО ^' = h is the distance from the center of the line of location of the ears of the head of the listener to the screen / or the line of location of the speakers / A, B / 1st and 2nd channels /,

AB = l is the distance between the sound emitters of the 1st and 2nd channels / AO = OB = l / 2 /,

d _goal - the distance between the ears of the listener,

α is the angle of rotation of the head of the listener when determining the imaginary point of the sound emitter in two-channel stereo.

We introduce the notation for the distance between points 1, 2, 3, 4, 5 / Fig. 4/:

Δ _1-2 = Δ _2-3 = Δ ₂ ;

Δ _5-4 = Δ _4-3 = Δ _i ;

Define a, b, c, d from the corresponding triangles / Fig. 4/:

With h = l / 2 = 1.5 m, d _goal. = 18 cm equations / 9 / are reduced to expressions;

/постоянная величина при заданных d_гол. и h/ относительно 1 /единицы/ и разложении функции: /1+х/^m в биномиальный ряд /берем 4 /четыре/ члена ряда/ получим /11/:Given the smallness

/ constant for given d _goals. and h / relative to 1 / unit / and the expansion of the function: / 1 + x / ^m in the binomial series / we take 4 / four / members of the series / we get / 11 /:

The desired function of the difference in the course of the sound wave from two sound emitters to the left and right ears of the listener from the number of possible combinations / b-a / and / c-d /:

Δ _z = ba-c + d.

We obtain, taking into account the equalities / 11 / after transformations, m:

This dependence / 12 / gives a maximum at 2α = 90 ° or α = 45 ° - the angle of maximum difference between the two points of definition of imaginary sound emitters in two-channel stereo due to the difference in the course of the sound wave from two sound emitters to the left and right ears of the listener from among the possible combinations / ba / and / cd /:

Δ _zmax = 3.82 · 10 ^-3 m = 0.382 cm,

which corresponds to the angle of rotation of the listener's head when determining the point of the sound emitter α ≅ 2 °, which, when summed with the angle of the random displacement of the listener's head by Δ _x ≤ 1 cm, leads to the determination of different points of the imaginary sound emitters from one primary sound emitter.

Consequently, the existence of a generalized equation for the difference in the path of a sound wave from two sound emitters of two-channel stereo to the left and right ears of the listener with different perception invariants:

creates additional points of imaginary sources of sound field relative to one primary sound source located in the space of reproduction of sound signals of transmitting devices.

This phenomenon is excluded in the present invention, because at each point in time of presentation of sound power, one / or more / a valid sound source corresponding to one / or more / primary point of a sound source sounds.

3 - imaginary points of sound emitters in stereo / for example, two actual sound emitters in two-channel stereo /.

With the exclusion of signals / b, d / or / a, c / in the analyzer that determines the point of the sound emitter, / Fig. 4/ we get the equalities:

Δ _A = / dc / = 0; Δ _B = / bd / = 0.

These equalities, obtained from equation / 13 /, are the conditions for the listener to determine the points of sound power emitters / A, B / / Fig. 4/. The points of sound power emitters A and B / as mono-emitters / do not provide information about the location of the true points of the primary sound emitters, but are essentially "redundant or imaginary" points of sound field sources that actually sound in the listening room.

This phenomenon is excluded in the present invention, because the sound field in the proposed device moves in space in accordance with the pulse-code signals of the movement of the primary sound sources / information about the primary points of the sound emitters is communicated to the listener only through the actual sound sources /.

4 - the versatility of the stereo system.

It is impossible in an analogue of the present invention to combine with two-channel stereo, four-channel stereo, quadraphone, panophony.

In the present invention, it is possible to reproduce the signals of the above stereo methods without increasing the cost of the construction of stereo broadcast receivers, because the stereo broadcasting method is switched by the pulse-code signals of the code channel of the transmitting devices, and the receiving device provides automatic adjustment of the broadcasting volume in accordance with the transmitted code.

5 - the accuracy of determining the points of sound sources in the stereo receivers.

The accuracy of determining the points by the sound emitter in the receivers of two-channel stereo / analogue / is limited by the displacement of the imaginary points of the sound emitters when the listener's head is shifted, the ambiguity of determining the same imaginary points of the sound emitters when the listener's head is offset, the appearance of additional imaginary points of the sound emitters due to travel differences from sound emitters of the 1st and 2nd channels of stereo to the left and right ears of the listener from the number of possible combinations, the “fuzziness” of the imaginary points of the sound emitters and -this interference phenomena from n sound emitters.

These phenomena give significantly worse angles for determining the imaginary points of sound emitters in two-channel stereo than α = 3 ° - the angle of rotation of the listener's head when determining the point of a sound emitter.

In the present invention, the accuracy of determining the points of sound emission in the receiving device is limited by the size and number of speakers used, the size of the screen / for example, television /.

The accuracy of determining the points of sound emitters in the present invention is practically unlimited and can strive for ideal accuracy / α ≤ 3 ° /.

The number of speakers used in the proposed stereo device can be quite small when using mechanical robots to move sound emitters in accordance with pulse-code signals / this improves the accuracy of determining the points of sound emitters /.

6 - coverage area of the stereo effect in the listening room of the receiving devices.

The coverage area of the stereo effect in the listening room of the receiving devices in the analogue of the present invention is significantly less than the area of the room. In addition, when moving over the area of the listening room of the listener, the definition points of the "imaginary points of sound emission" are shifted relative to the image on the screen / television / of these points of sound emission.

In the present invention, the coverage area of the stereo effect in the listening room of the receiving devices is not limited, because the stereo effect is created by moving the sound source when switching the speaker number in accordance with the transmitted code, rather than a static system of two speakers as in the analogue, the information of one channel at any time can be in one / or more / sound emitters.

Thus, in the present invention, at any point in the listening room, the points of emission of sound and the images of the same points on the screen are uniquely determined / exact coincidence of the points of sound and video regardless of the movements of the listener /.

7 - the combination of stereo with monophonic broadcasting.

The combination of stereo and monophonic broadcasting in an analogue of the present invention is difficult to implement, leads to a deterioration in the sound quality of the signals perceived by the listener / for example, partial suppression of the subcarrier frequency, algebraic summation of the signals of the left and right stereo channels, etc. /.

In the present invention, the combination of stereo with monophonic broadcasting is carried out when the code cacal and three of the existing four signal channels are turned off. In this case, the volume of sound signals corresponds to the previously set amplitude for monophonic broadcasting (i.e., the volume of sound signals remains unchanged when switching from stereo to monaural broadcasting).

In the present invention, when switching from stereo to monophonic broadcasting, there is no deterioration in sound quality, because transformations of the useful signal leading to a change in the spectrum of / also in the reverse transition are excluded.

8 - the identity of the stereo channels.

The identity of the stereo channels in the analogue of the present invention determines the quality of the stereo effect / the absence of phase distortion /.

In the present invention there is no question of the identity of the stereo channels, because 4 / four / wideband audio channels existing in the invention and 1 / one / narrowband / code / channel are mutually independent / transient attenuation between channels is greater than or equal to 60-100 dB /, and when transmitting single-channel stereo / 1 / one / wideband audio channel and 1 / one / narrowband / code / channel / with the movement of the sound source in space in accordance with the pulse-code signals of transmitting devices, the question of channel identity is not worth more.

9 - creeping of signals of two or more channel stereo from one channel to another when dividing stereo channels.

The signal creep between the channels in the analogue of the proposed invention of two-channel stereo is determined by the amount of transitional attenuation / β / of the entire signal transmission line from the studio to the receiver, which can be measured by separation of the stereo channels. To maintain a good stereo effect, the amount of transition attenuation taking into account the interdependence of the signal channels should be equal to or greater: β ≥ 25 dB.

In the present invention, there are from one to four independent signal channels with a frequency band Δ f = 16-20 kHz and one narrow-band channel / independent of the other channels / with a frequency band Δ f = 1-10 kHz for pulse-code signals, transition attenuation between which may be equal to or greater than β ≥ 60-100 dB, which is much better than the analogue.

10 - automatic adjustment of sound power with n sound emitters.

Automatic adjustment of sound power with two sound emitters in the analogue of the present invention / two-channel stereo / is not provided.

In the present invention, each of n sound emitters can emit different sound power at each moment of time in accordance with the pulse-code signals of transmitting devices. Thus, in the present invention, it is possible to implement a stereo method - panophony.

In addition, in the present invention, it is possible with the simultaneous sounding of n _x sound emitters limiting the total power of sound emitters in accordance with the transmitted pulse-code signal of transmitting devices / or a threshold limiter of the total power of n _x sound emitters - automatic adjustment /.

11 - directivity of the horns of sound emitters.

The directionality of the horns of the sound emitters determines the naturalness of the sound reproduced in the receiving device signals, which is not in the design of the analogue of the invention.

In the present invention, the horns of each sound emitter of the receiver may, in accordance with the pulse-code signals of the transmitting devices, occupy a certain position in space along the x, y axes.

12 - interference phenomena from n sound emitters.

Interference phenomena in two-channel stereo / analogue / with algebraic addition / transformations / signals of two channels create significant distortion.

In the present invention there are no interference phenomena from n sound emitters, because the 4 / four / signal channels existing in the invention are interdependent, and single-channel stereo with the movement of sound sources in space in accordance with the pulse-code signals of transmitting devices, in principle, cannot produce interference phenomena. The interference phenomena of sound signals from the addition of signals from sound emitters / speakers / in the perception space of listeners are natural or predetermined creators of stereo transmission.

13 - mechanical movement of sound sources by electronic-mechanical robots.

Mechanical movements of sound sources in the present invention by electronic-mechanical robots create greater accuracy in reproducing points of sound sources in the stereo receiver in accordance with the pulse-code signals of transmitting devices / screen x, y plane in the present invention - Fig. 5 / with a significantly smaller number of effective the receiver of sound sources relative to similar devices without electronic-mechanical robots.

In addition, electronic-mechanical robots can create a directional horns of sound emitters.

In the analogue of the present invention there are no mechanical movements of sound sources, which limits the accuracy of determining sound sources in the receiving device.

14 - quality stereo effect.

The quality of the stereo effect / s / in the analogue of the invention and in the invention is defined as the ratio:

where Δ _perv is the minimum distance between the primary points emitting sound energy that a transmitting device can transmit.

Δ _receiver - the minimum distance between points emitting sound energy, about which the receiving device can transmit information to the listener.

In the present invention, the quality of the stereo effect tends to 1 / unit /: s → 1 with the number of emitters of the sound of the receiver, tending to a large value, and small geometric dimensions of devices emitting sound, / it should be noted that a high resolution of transmitting devices providing information on location in space of primary points of sound emitters.

Thus, the determination of sound emission points can be better than α = 3 ° / the angle of rotation of the listener's head when determining the point of the sound emitter / and leads to an improvement in the quality of the stereo effect when using electronic-mechanical robots that move sound power emitters in space in accordance with the pulse code signals of transmitting devices.

In the analogue of the present invention, the stereo effect quality is much worse than the invention due to imaginary sound sources that shift when the listener shifts in the listening room / or involuntary displacements of the listener’s head / - poor stereo effect quality during a long static scene, the difference in the sound wave path from sound emitters 1- the first and second channels of stereo to the left and right ears of the listener; interference phenomena from n sound emitters: determination of sound emission points may be worse than α = 3 ° / angle of rotation of the listener's head when determining the point of sound emitter /.

15 - the number of applied sound sources in stereo receivers.

In the present invention, in contrast to the analogue / where there are only two sound sources corresponding to two stereo channels / there are N sound sources / two or more / distributed in space / plane and volume / premises for listening / viewing / stereo broadcasts that can be activated in any combination of a given number n _x speakers from the total number N of sound sources of the receiving device by the mechanical installation unit of a given number n _{x of} sound emitters.

The total number N of sound emitters, together with a certain number of applied electronic-mechanical robots in the proposed stereo device, determine the accuracy of determining the sound sources in the receiving device.

It should be noted that in the proposed stereo device with one / or from one to four / useful signal channel there are n _x different sound sources transmitting sound signals from n _x different points in space.

The existence in the design of the analogue of the invention of only two valid sound sources limits the accuracy of determining sound sources due to the instability of perception of imaginary sound sources, etc.

16 - broadband signal channels of stereo devices.

The currently existing method of two-channel stereo / analogue of the invention / defines two broadband signal channels with a frequency band Δ f = 16-20 kHz.

In the present invention, with a single-channel / or four-channel / stereo phone with movement in the “listener perception space” of sound sources in accordance with the pulse-code signals of transmitting devices, there are two / or five / signal channels:

1st / or 1st to 4th / - broadband channel for audio signals with a frequency band Δ f = 16-20 kHz;

2nd / or 5th / - narrowband channel for pulse-code signals with a frequency band Δ f = 1-10 kHz.

Thus, by the method of the present invention, it is possible to carry out stereo transmissions in the frequency band, which determines the standard of the existing television channel: 0-8 MHz.

Therefore, when introducing the proposed stereo into the currently existing analog television channels, one high-quality / Δ f = 16-20 kHz / FM sound channel / existing in the channel / can be activated and one narrow-band pulse-code channel / Δ can be introduced f = 1-10 kHz / in the protective zone of the television channel / Δ f = 0.125 MHz /.

The introduction of stereo sound into analog television channels by the analogue method, where there are two broadband audio channels, is not possible, because, in addition to the above disadvantages of this method: the mismatch of the video points on the television screen and the same points corresponding to the sound sources that the listener defines with your hearing aid when the listener is displaced in the listening room, etc., it is impossible to fit in the channel strip in accordance with the accepted standard the 2nd analog broadband audio channel / il and two identical digital broadband audio channels to a greater degree.

SUMMARY OF THE INVENTION

The essential features of the invention, providing the corresponding technical result:

1 - the coincidence of the points of the sound emitters on the television screen / determined by the eyes of the listener / and the points of determination of sound sources by the listeners / binaural effect / in the viewing / listening room / stereo television broadcasts at the displacements of the listener's head / or the displacements of the listener in the room /.

The above technical result is provided in the present invention by a large variation in the location of sound sources in the space behind the television screen when switching the nth sound source / or n _x sound sources / in accordance with the pulse-code signals of transmitting devices and the existence of only valid sound sources.

2 - lack of additional variation of imaginary sound field sources relative to one sound source located in the plane of the television screen or space behind the screen, due to the influence of the difference in the course of sound waves from two or more sound emitters in the stereo broadcast receiver to the listener's left and right ears, which determines point of sound emitter.

The above technical result is ensured in the present invention by the existence of only valid sound sources that are switched in space behind the television screen in accordance with the pulse-code signals of transmitting devices / or sound radiation at each moment of time, only one valid sound source from the total number of sound sources used in stereo device.

3 - absence of imaginary / or extra / points of sound emitters in stereo.

4 - the versatility of the stereo system.

In the present invention, it is possible to stereo with N sound emitters, which are turned on in accordance with the pulse-code signals of transmitting devices and emit sound energy of different volume levels for each sound emitter in accordance with the code channel signals, combined with 2-channel / 4-channel stereophony at 2/4 / signal channels of sound frequency, quadraphony, panophony.

This design of the invention provides a technical result - the versatility of the stereo system.

5 - the accuracy of determining the points of sound emitters in stereo receivers.

In the present invention, the accuracy of determining the points of sound emission in the receiving device is limited by the size and number of speakers used, the screen size of the projection television receiver.

The accuracy of determining the points of sound emitters in the present invention is practically unlimited and can strive for perfect accuracy: α ≤ 3 ° - to the angle of rotation of the listener's head when determining a point of a sound emitter less than or equal to three degrees / maximum accuracy for a person, at which it is possible to distinguish between two adjacent points of sound emitters.

The number of speakers used can be quite small when using electronic-mechanical robots to move sound emitters in space in accordance with the pulse-code signals of transmitting devices that improve the accuracy of determining the points of sound emitters.

This design of the invention provides a technical result: the accuracy of determining the points of the sound emitters, corresponding to the angle of rotation of the head of the listener when determining the point of the sound emitter, equal to or less than three degrees.

6 - coverage area of the stereo effect in the listening room of the receiving devices.

In the present invention, the coverage area of the stereo effect in the listening room of the stereo receivers is not limited, because the stereo effect is created by moving the sound source when switching the speaker number in accordance with the transmitted code / only valid sound sources /, and not a static system of two speakers / analogue / that gives information about imaginary sound sources. The information of one sound channel can be at one time in one / or n _x / sound emitter, i.e. at any point in the room for viewing / listening / stereo television broadcasts, sound emission points / binaural effect / and images of the same points on the screen / exact match of sound and video points regardless of the movement of the listener / are uniquely determined.

This design of the invention provides a technical result: an unlimited coverage area of the stereo effect in the listening room of stereo receivers.

7 - the combination of stereo with monophonic broadcasting.

In the present invention, the combination of stereo and monaural broadcasting is carried out in accordance with the code of the transmitting devices / or the specified code of the receiving device / without deterioration in sound quality / no transformations of the useful signal leading to a change in the spectrum /.

This design of the invention provides a technical result: the combination of the proposed method of stereo with monophonic broadcasting without compromising sound quality.

8 - creeping of signals of two / or more / channel stereo from one channel to another when dividing stereo channels.

In the present invention, there are from one to four independent signal channels in the frequency band Δ f = 16-20 kHz and one narrow-band channel with the frequency band Δ f = 1-10 kHz for pulse-code signals / also independent of other channels /, transition attenuation / β / between which there may be β = 60-100 dB.

This parameter of the invention provides a technical result: a good stereo effect without cross-distortion of the signals of the respective channels.

9 - the identity of the stereo channels.

In the present invention there is no question about the identity of the channels, because the 4 / four / sound channels existing in the invention are interdependent / transient attenuation between channels β ≥ 60-100 dB /, and with single-channel stereo with the movement of sound sources in space in accordance with the pulse-code signals of transmitting devices, there is no question of channel identity in a larger degrees.

This design of the invention provides a technical result: high quality stereo effect with the independence of the four audio channels / the absence of phase distortion / without the requirement of channel identity.

10 - automatic adjustment of sound power with n sound emitters.

In the present invention, each of n sound emitters can radiate at each instant of time a different sound power in accordance with the transmitted pulse-code signals of the transmitting devices.

This design of the invention provides a technical result: the implementation of the stereo method - panophony and limiting the total power of the sound emitters when they are simultaneously played.

11 - directivity of the horns of sound emitters.

In the present invention, the horns of each sound emitter of the receiver may, in accordance with the pulse-code signals of the transmitting devices, occupy a certain position in space along the x, y axes.

This design of the invention provides a technical result: the directionality of the horns of the sound emitters determines the naturalness of the sound reproduced in the receiving device signals.

12 - interference phenomena from n sound emitters.

In the present invention there are no interference phenomena from n sound emitters, because the 4 / four / signal channels existing in the invention are interdependent, and single-channel stereo with the movement of sound sources in space in accordance with the pulse-code signals of transmitting devices, in principle, cannot create interference phenomena.

This design of the invention provides a technical result: the absence of interference phenomena from n sound emitters.

13 - mechanical movement of the sound source by electronic-mechanical robots.

Mechanical movements of sound sources in the present invention by electronic-mechanical robots create greater accuracy in determining the sound source in accordance with the pulse-code signals of transmitting devices with a significantly smaller number of sound sources involved in the receiving devices. In addition, electronic-mechanical robots can create directional horns of sound sources.

This design of the present invention provides a technical result: the ability to move sound sources over distances tending to a small value (zero), leading to greater accuracy in determining sound sources and to the required smaller number of sound sources used in receiving devices, the possibility of a certain orientation of the horns of sound emitters.

14 - stereo effect quality.

The stereo effect quality / s / in the present invention tends to 1 / unit /: s → 1 with the number of sound emitters of the receiver, striving for a larger value, and small geometric dimensions of the devices emitting sound. It should be noted that a high resolution of transmitting devices providing information about sound sources is necessary when determining the leakage of sound emitters with an accuracy corresponding to an angle equal to or less than 3 ° / angle of rotation of the head of the listener when determining the point of the sound emitter /, which leads to improved quality stereo effect when using electronic-mechanical robots that move sound power emitters in space in accordance with the pulse-code signals of transmitting devices.

This design of the invention provides a technical result: high quality stereo effect, determined by the value:

tending to unity at any accuracy in determining the primary points of sound emitters of transmitting devices.

15 - the number of applied sound sources in the stereo receiver.

In the present invention, there are N sound sources / two or more / distributed in space / plane and volume / space for listening / viewing / stereo television broadcasts. Any given number of n _x speakers from the total number N of sound sources of the receiving device can be activated by the mechanical installation unit of a given number of n _x sound emitters. A predetermined number n _{x of} sound emitters determines the accuracy of determining the sound sources in the receiving device.

This design of the invention provides a technical result: the ability to use a given number of sound emitters and in accordance with a given accuracy of determining the sound source, limited by the maximum number of sound emitters of the stereo receiving device.

16 - broadband signal channels of stereo devices.

In the present invention, there are from two to five signal channels:

from one to four broadband channels for audio frequencies with a band Δ f = 16-20 kHz;

2nd / or 5th / narrowband channel for pulse-code signals with a frequency band: Δ f = 1-10 kHz.

Thus, by the method of the invention it is possible to carry out stereo television broadcasts in the frequency band determined by the standard of the existing television channel: 0-8 MHz.

Therefore, when introducing the proposed stereo method into the currently existing analog television channels, one high-quality FM sound channel existing in the analog channel / Δ f = 16-20 kHz / can be activated and one narrow-band pulse-code channel / Δ can be introduced f = 1-10 kHz / in the protective zone of the television channel / Δ f = 0.125 MHz /.

These parameters of the present invention provide a technical result: the introduction of stereo audio transmissions into currently existing analog / or digital / television channels.

The proposed method of stereo is to reproduce in the receiver sources of sound power located in the plane of the television screen or in space behind the screen, regardless of the rotation or movement of the head of the listener / or the listener himself in the room for listening / viewing / stereo television broadcasts /. At any point in the room where the stereo television broadcast is viewed / listened to, there will be a coincidence of the sound points of the transmitted image of the sound sources and the same points of the sound sources of the transmitted sound signals determined by the hearing aid of the listener.

There are no imaginary points of sound field sources in this stereo device.

The block diagram of the device according to the "method of stereo stereo with movement in the perception space of listeners of sound sources in accordance with the pulse-code signals of the primary points of the sound emitters" is presented in Fig.5.

The maximum number of speakers / sound sources / in the plane of the television screen and the space behind the N _max screen is assumed to be 100 / hundred / with the television screen area of the receiving stereo device approximately 10 m ² .

Each cell of the sound emitter N _x consists of a controlled stabilizer / 1 /, which, in accordance with the transmitted code, turns on / off / the sound emitter / D1 / and the amplifier / 2 /; counting trigger / 3 /, including the first input pulse and turning off the stabilizer with the second input pulse; input transformers / Tr.1, Tr.2 / pulse-code channel and sound signal channels; a signal processing unit α _x , _y / 4 /, a memory unit for codes α _{x, y} / 5 /, a code selector α _{x, y} / 6 /, giving the necessary information about the directionality of the horns of sound emitters.

The code channel matrix block / I / consists of N _max cells of sound emitters decoupled by diodes. The inclusion of each cell N _x occurs in a given period of time t _x blocks of horizontal / 7 / and vertical / 8 / rows.

At the frequency of the “1 kHz generator” / 10 / matrix of the code channel matrix f _r1 = 1 kHz, which corresponds to t _x = 1 ms, the total time of information input for the number of cells is N _max = 100: tΣ = 0.1 sec.

During the switching on of one cell N _x t _x = 1 ms, information can be entered with a five-digit code / t and _{.min. int} . = 50 μs / o α _{x, y} - rotation angles of the directional horn of the cell speaker N _x / input 7 of the modulator / 11 / code channel matrix and the code numbers n1 / 1-10 / and n2 / 1-10 /, which correspond certain rows of the code channel matrix vertically and horizontally, determining the value of the number N _x - the number of inclusion of the cell of the sound emitter. The signals α _{x, y} are fed through the modulator to the load resistance of the block of vertical rows / r ₁ /. Signals n1 / 1-10 /, n2 / 1-10 / are entered into blocks of horizontal and vertical rows of the code channel matrix.

Then, information about the number of the cell switching sound emitter N _x and the angles of rotation of the directional speaker of the cell / D1 / is supplied from the output of the code channel matrix block / outputs 1, 2 / to the inputs of the corresponding cell N _x / inputs 1, 2 Tr.1 /.

When changing information on the blocks of horizontal and vertical rows of the matrix of the code channel / input 6 /, an impulse for changing information is supplied.

The memory circuit blocks of horizontal and vertical rows code channel matrix is introduced for a given number of simultaneous switching speaker _x n / N _x or -x cells sound emitters / information code numbers n1 / 1-10 /, n2 = / 1-10 /, which is then repeats with the given sequence.

To exclude clicks in the dynamics when switching on / off / the corresponding cell of the sound emitter N _{x, the} duration of the cell switching pulse is equal to or greater than t _on ≥ 0.1 sec.

If it is necessary to turn on a certain number of sound emitters, less than N _max = 100, there is a mechanical installation unit in the code channel matrix for the set number of _{x x} sound sources / 9 /, in which the number of sound emitters n _x ≤ N _{max is} set using jumpers.

The block diagram of a stereo device includes a VCR / 12 / that reproduces television signals that can be input to a projection television system, and a five-channel VCR / 13 / that reproduces audio signals from four signal channels U _sl 1-4 and signals from one pulse-code channel / U _code /. The five-channel audio tape recorder is synchronized from the VCR.

The number of signal channels in the proposed stereo device is accepted by four, i.e. each signal channel U _SL 1-4 corresponds to the corresponding blocks of the signal matrix of the channels: II-1-II-4.

Each of the 4 matrices / outputs 3, 4 / of the signal channel is connected to the input of the amplifiers N _x cells of the sound emitters / inputs 3, 4 of the transformer Tr.2 / through decoupling diodes, while the signals U _sl 1-4 can be supplied independently from each other to any cell N _x / or n _x cells / from N _max .

With the frequency of the “300 kHz generator” / 17 / of the signal channel matrices 1-4 f = 300 kHz / out.5/, the maximum frequency of the sound signal Ω _max = 16 kHz and the selected maximum number of simultaneously emitted sound emitters 4 / four / in each of 4 signal matrices per Ω _max sound signal U _sl 1-4 information about five points will be transmitted.

The total number of sound emitters turned on at one time in 4 signal matrices in accordance with signals n1 / 1-10 /, n2 / 1-10 / is 16 / sixteen /.

At the inputs of 8-11 modulators / modulator / 18 / - for the matrix block of the 1st signal channel of the audio frequency - input 8 / blocks of matrixes of the signal channels of the audio frequency 2-1 - 2-4 information about the signals of the audio frequency U _sl 1-4 with a frequency band Δ f = 16-20 kHz and loudness of the reproduced signal / A _n / by each sound emitter of the corresponding matrix through a television receiver / 24 /, code selector N _x , A _n , α _x , _y / 25 /, digital-to-analog converter / 27 /.

Audio signals are removed from the television receiver / 24 / - output U _SL 1-4 / 8-11 / or from a five-channel audio tape recorder / 13 /.

The signals from the modulator / 18 / are applied to the load / r2 / of the block of vertical rows / 15 /.

Information on the numbers n1 / 1-10 /, n2 / 1-10 /, is entered into the memory circuit of blocks of horizontal / 14 / and vertical / 15 / rows in each of the 4 matrixes of signal channels for a given switching number N _x cells of the sound emitter which is then repeated with a given sequence.

When changing information on the blocks of horizontal and vertical rows / 14, 15 / - input / 6 / matrices of the signal channels of the audio frequency, an impulse for changing the information is supplied.

In the unit for the mechanical installation of a given number n _x sound sources / 16 / in each of the 4 matrices of signal sound channels, a specified number of sound emitters can be set using jumpers for n _x ≤ N _max .

At the telecentre / radio center /, the following are automatically determined: the activation code n _x 1-4 is the cell number of the sound emitters of each block of the matrix of signal channels of the audio frequency with the automatic code identifier n _x 1-4 / 19 /, the code corresponding to a certain volume level of each sound emitter from N _max , automatic code identifier A _n 1-4 / 20 /; code corresponding to the rotation angles of the directional speaker horn, automatic code identifier α _{x, y} 1-4 / 21 /.

After blocks 19, 20, 21, the output signals of these blocks together with 4 signal sound channels / frequency band of each of these channels Δ f = 16-20 kHz / - signals U _sl 1-4 are fed to the pre-amplifier of the telecentre / 22 /.

Then, after transformations, the total output signal of the block / 22 / is fed to the transmitter of the telecentre / 23 /.

When using in the present invention a single signal broadband audio channel / frequency band Δ f = 16-20 kHz / currently existing in analog television channels / this channel occupies the frequency band Δ f _sound in the frequency band of the television channel 0-8 MHz = 250 kHz / and one narrow-band pulse-code channel with a frequency band Δ f _code = 1-10 kHz, the necessary frequency band for the implementation of the proposed stereo method fits in the frequency band of a television channel 0-8 MHz, because an additional narrow-band pulse-code channel with a frequency band at the transmitter output Δ f = 20-50 kHz fits in the protective zone of the analog television channel / Δ f = 0.125 MHz /.

To receive signals n1 / 1-10 /, n2 / 1-10 /, corresponding to the inclusion number n _{x of the} cell of the sound emitter, the code signal passes through a television receiver / 24 /, code selector N _x , А _n , α _{x, y} / 25 / to the converter N _x → n1,2 / 26 / and then to the signal selector n1,2 / channels 1-4 / / 28 /. This snob of receiving signals n1,2 gives the most optimal frequency band occupied by these signals.

It should be noted that the total volume level of the transmitted signals with the simultaneous inclusion of n speakers does not exceed the natural level of the signals in the present invention, which is automatically adjusted.

In the currently existing analog television channels, in which one broadband channel / frequency band Δ f = 16-20 kHz / is used to transmit audio signals, two matrices can be used to implement the proposed stereo method: I - code channel matrix; II - matrix of the 1st signal channel of sound frequency.

Thus, it is possible to implement single-channel / or 4-channel / stereo with movement in the space of sound sources with the number of simultaneous sounding of these sound sources no more than 4-16 with different amplitudes. In this case, the frequency of the matrix compaction generator is f _g = 300 kHz. At frequencies of the matrix compaction generator, greater than 300 kHz / for example, 1 MHz /, it is possible to turn on 48 / forty-eight / sound sources with different amplitudes at the same time.

When transmitting signals from one telecentre to another, the signals of the proposed stereo method can be converted into 2-channel stereo signals / two sound sources without switching sound sources or without moving in the space of sound sources in accordance with the transmitted pulse-code signals / and vice versa.

1. The design of the device according to the aforementioned method of stereo communication consists of n cells of sound emitters located in the receiving device location in a certain geometric order, while the sound emitters are fixed in certain coordinates of the above room. Each cell of the sound emitter can be turned on or off in accordance with the pulse-code signals of the transmitting side, in addition, the signals of any of the 4 signal channels of the audio frequency can be sent to the inputs of the cells of the sound emitters when these signals are switched by blocks of matrixes of the signal channels of the audio frequency. Therefore, the proposed method of stereo allows you to move sound sources in the space of the location of the receiving device or perception of listeners in accordance with the pulse-code signals of the transmitting side.

It should be noted that the primary points of the sound emitters are located on the transmitting side, for example, a movie studio, television studio, theater stage, and are primary or primary, and the cells of the sound emitters are located on the receiving side and are secondary or repeating the primary points of the sound emitters in the stereo signal receiver.

According to the Little Soviet Encyclopedia, 1960, T.8 definition of stereo on page 1123: transmission or reproduction of sound, which retains the perception of the spatial arrangement of sound sources. It should be noted that the purpose of the proposed stereo method, the definition of which is indicated in the T.8 encyclopedia, is realized in the case of the implementation of the device according to the method of claim 1: switching sound sources located in the location space of the stereo receiving device in a certain geometric order, or moving to the space of perception of listeners of sound sources, because in accordance with the pulse-code signals of the transmitting side, information is transmitted in binary code on the coordinates or spatial arrangement of the primary points of the sound emitters to the stereo receiver, while the above-mentioned pulse-code signals in combination with the audio frequency signals of the sound frequency signal channels transmitted with a certain synchronism , represent the generated stereo signal according to the proposed method for the implementation of stereo. In this case, there is a time dependence of the sound sources reproduced in the stereo receiver and location coordinates codes, sound amplitudes, directional angles of the horns of these sound sources in accordance with the pulse-code signals transmitted in the narrow-band code channel, in contrast to the polar modulation stereo method, where between the two channels of sound frequency there is a phase dependence of the sound frequency signals.

The generated stereo signal can be transmitted, except for a narrow-band code channel, for example, in one audio frequency channel during the sounding of each sound source from the nth number of sound emitters existing in the receiving device at different time intervals. Moreover, the pulse-code signals transmitted by the transmitting side in the narrowband code channel do not carry information about the audio frequency signals of the corresponding channel of the audio frequency, but carry information about the spatial location of the sound sources, for example, transmitting the coordinate codes of sound sources or "moving in the perception space of source listeners sound. "

The purpose of the proposed method of stereo is carried out in the device, which in a static state represents the n-th number of cells of sound emitters located in the listening room of stereo broadcasts in a certain geometric order. The inputs of the above cells are fed signals from a stereo receiver, consisting of a code channel matrix block, four audio frequency signal channel matrix matrices, a television receiver, code selector N _x , A _n , α _{x, у} ; Converter N _x → n1,2; digital-to-analog converter, signal selector n1,2 / channels 1-4 / / cm. figure 5 /.

For certain pulse-code signals corresponding to the location of one of the nth number of sound emitters, a certain cell number of the sound emitter is turned on, the sound frequency signals of one signal channel of the sound frequency are fed to its inputs. The above-mentioned pulse-code signals are determined on the transmitting side by the apparatus for generating these signals, in particular, by automatic code identifiers. With the simultaneous sounding of 4 points of sound emitters on the transmitting side, four cells of sound emitters in different coordinates are switched on at the same time at the inputs of which sound frequency signals from 4 sound signal frequency channels are supplied.

The sound sources in the receiving device are at the same time of sounding in the same coordinates as the primary points of the sound sources on the transmitting side, provided that the 1: 1 scale of the premises is the location of the sound sources on the transmitting and receiving sides.

2. The proposed method of stereo sounding is carried out by switching n cells of sound emitters located in a certain geometric order on the receiving side, in accordance with the transmitted side of the narrow-band code channel pulse-code signals of the transmitting side, which correspond to certain coordinates of the above cells. With these code signals, the code channel matrix includes the corresponding ni cell of the sound emitter from the total number of n cells using a controlled stabilizer / 1 - see Fig. 5 / and a counting trigger / 3 - see Fig. 5 / cell switching pulse applied to the input 1, 2 ni sound emitter cells. At the same input 1, 2 are supplied pulse-code signals corresponding to the directivity angles of the horns of sound sources.

In accordance with the same pulse-code signals corresponding to the coordinates of a certain cell, audio signals can be applied or 1: 4 audio channels of the audio frequency can be switched to input 3, 4 of the sound emitter cell using the corresponding blocks of matrices 1-4 of the audio signal channels frequency. Then, the sound frequency signals pass through the amplifier / 2 - see Fig. 5 / cells of the sound emitter and fall on the sound emitter - speaker D1 / cm. 5 / cell emitter sound. Moreover, for different signal channels of sound frequency, different cells of sound emitters are switched on.

Thus, it is possible to implement the proposed stereo method “by switching n cells of sound emitters in accordance with the transmitted pulse-code signal of transmitting devices in a narrow-band code channel when switching from one to four signal channels of sound frequency to the above cells of sound emitters”.

3. Pulse-code signals corresponding to the coordinates of sound emitters located, for example, in the studio on the transmitting side, sound amplitudes of the same sound emitters, directional angles of the horns of the same sound emitters necessary for the functioning of the receiving device according to the proposed method of stereo sounding, depend only from the location on the transmitting side of the sound emitters, their sound amplitudes and directivity angles of the sound wave. The above sound emitters on the transmitting side are the primary points of the sound emitters. On the receiving side, in the cells of the sound emitters located in the volume of the room where the stereo receiver is located in a strict geometric order with a predetermined interval between the sound emitters, a certain number of the sound emitter cell is turned on, a certain sound amplitude of the sound is emitted, the directional angles of the horns of the sound emitters are pulsed code signals coming from the transmitting side. Thus, the state of the cells of the sound emitters on the receiving side depends only on the pulse-code signals of the transmitting side.

The choice of a given number of sound emitters on the receiving side determines only the fidelity of stereo signals coming from the transmitting side with a certain specified accuracy of determining the point of the sound emitter.

4. A method for generating pulse-code signals corresponding to specific coordinates of sound emitters, sound amplitudes and directional angles of horns of sound emitters on the transmitting side, for example, in a television center studio, provided that the emitters have a 1: 1 scale of arrangement of sound emitters on the receiving and transmitting sides or the studio has the same geometric dimensions and the location of the location of the stereo receiving device is carried out using automatic code identifiers: coordinates N _x 1-4, sound amplitude A _n 1-4; horn angles α _{x, y} 1-4.

For a given number of sound emitters in the receiving device, for example, one hundred, the reproduction of stereo signals is carried out with appropriate accuracy. In order for the sound emission to come from no more than 4 sound emitters, sounding simultaneously, it is necessary that the script, for example, a theatrical production, be written accordingly.

When playing a television broadcast on the screen area of a television receiver: S = 10-20 m ² accompanied by stereo sound / n sound sources located in a certain geometric order behind the screen, while signals 1 are sent to the above sound sources in accordance with pulse-code signals -4 signal channels of sound frequency / the linear dimensions of the sound emitters corresponding to the primary points of the sound emitters, for example, parts of the singer’s body, and the coordinates of the sound emitters vary significantly elevizionnom screen while changing the parameters of the optical systems transmit television cameras located in a television studio, which is the transmission of television pictures of different fragments aforementioned general TV station plan. From which it follows that it is advisable to determine the primary points of sound emitters in the studio automatically as follows: 16 sound emitters that can be in a television frame and sound simultaneously / four sound emitters - for each sound channel of the audio frequency with 4 stereo speakers in the receiver sound channels of sound frequency /, emit sound frequency signals with different sound amplitudes.

These signals are received by miniature microphones with amplifiers, providing close interaction of perceived signals, which are transmitted to miniature radio stations operating at different high-frequency frequencies. In these radio stations, there is a radio code generator that corresponds to the number of the radio station, while the above code generator modulates the 2nd narrow-band channel / 1st channel corresponds to the audio / signal channel, occupying a frequency band from 35 to 38 kHz. In addition, the same code generator modulates the LED located on the radio station’s body, while the above LED emits electromagnetic energy outside the range of visible light that enters the television camera of the transmitting side, on which an additional transmitting tube is mounted. The additional transmitting tube receives signals only from the LED, as the above additional transmitting tube is equipped with a suitable optical filter / scan generator in the camera is common, and the lenses are connected mechanically to achieve one focal length for the additional and main transmitting television tubes of the camera /. Thus, the size in the frame of the transmitted television image is the same in all the involved transmitting tubes.

The coordinates of the primary points of the sound emitters are determined on the transmitting side as follows: a high-frequency signal receiver receives signals from 16 radio stations or 16 primary points of sound emitters. Then these signals are transferred to the sound engineer’s console, where they are converted into four signal channels of the audio frequency U _sl 1-4, while each of the 16 signals of the primary points of the sound emitters is formed with its own sound amplitude. Signals U _SL 1-4 are fed to the pre-amplifier of the telecentre / 22 - see _figure 5 /. Code signals corresponding to the coordinates of the primary points of the sound emitters or the cell number of the sound emitter on the receiving side from the automatic code identifier N _x 1-4 / 19 are received at the same block 22 - see Fig. 5 / in a specific time sequence. Block 19 is supplied with code signals corresponding to the coordinates of the primary points of the sound emitters from the camera and code signals corresponding to the number of the radio station, from the camera and radio station.

When counting the number of scan lines of the additional transmitting tube of the camera, a light signal appears from the LED located on the case of one of the 16 radio stations at the corresponding line length. The value of the number of the nth line and the length of the corresponding line when counting in the computing unit of the camera are code numbers N _x 1-4 corresponding to the coordinates of the primary points of the sound emitters on the transmitting side or a specific cell number of the sound emitter on the receiving side. When the codes of the radio stations going through the air from the 2nd channel of the radio station and the codes of the same stations coming from the camera coincide, in block 19 the codes of numbers N _x 1-4 are grouped into four in accordance with the determined signal channels of the audio frequency. One of the 4 sound emitters is selected as the main one, the remaining three sound emitters are selected as auxiliary. The signals of all 4 sound emitters are entered into a single signal channel of sound frequency with different sound amplitudes.

The sequence of codes of numbers N _x 1-4 at the output of block 19 is unique: from the 1st to the 16th.

Then comes the sequence of codes of amplitudes of sound of the primary points of sound emitters, the code signals of which from 16 radio stations are entered into the automatic code identifier A _n 1-4 / 20 - see Fig. 5 /. On the same block 20 are coded signals from the camera and radio stations corresponding to the number of the radio station.

When the above codes coincide in block 20, the sound amplitude codes of the primary points of the sound emitters A _n 1-4 are grouped, obtained from the analog-to-digital converter of the sound engineer board. The sequence of codes of numbers And _n 1-4 at the output of block 20 is unique: from the 1st to the 16th.

The directional angle codes of the horns of the primary points of the sound emitters are determined in the automatic code identifier α _{x, for} 1-4 / 21 - see Fig. 5 /. The directional angles of the horns α _{x, y} 1-4 of sound sources are determined in n television cameras located along a certain radius r in the studio through α ≥ 15-30 °. When you turn the sound source in the studio of the transmitting side at a certain angle, the radio station with the LED equipped with a reflector turns with it. On one of the n cameras, an LED signal appears with the code signal of the radio station, while ni the camera determines the sector corresponding to the discrete value α _{x, y} . In addition, each television camera can provide information about the angles of directivity of the horns of several sound sources, because each sound source with a different geometric arrangement in the studio corresponds on the transmitting tube of the nth camera to a certain vertical line number and a horizontal line length segment. The analog values of the values α _{x, y} 1-4 in the corresponding television cameras are converted in analog-to-digital converters into the code values of these quantities, which are fed to the input of block 21. Code signals from television cameras and radio stations corresponding to the number of the radio station are received on the same block 21. When the above codes coincide in block 21, a grouping of codes corresponding to the values of the directivity angles of the horns of sound sources occurs. The sequence of codes of numbers α _{x, y} 1-4 at the output of block 21 is unique: from the 1st to the 16th.

The sequence of codes N _x 1-4, An1-4, α _{x, y} 1-4; entered in the pre-amplifier telecentre / 22 - see figure 5 /, is unambiguous in the above sequence.

Signals N _x 1-4, A _n 1-4; α _{x, y} 1-4; U _sl 1-4 start up in block 22 and then through the high-frequency generators of the transmitter of the telecentre / 23 - see figure 5 / are broadcast. In block 22 and a television receiver / 24 - see figure 5 / it is possible to adjust the maximum sound level of the total signal of the sound channels U _sl 1-4.

In addition, it is possible to generate pulse-code signals artificially using a single-pulse generator of a five-channel audio tape recorder / 13 - see Fig. 5 /, for recording into the narrow-band pulse-code channel of the aforementioned audio tape recorder, the signal codes N _x 1-4; A _n 1-4, α _{x, y} 1-4, before the corresponding point in time of sound sources 1-4 signal channels of the audio frequency. All channels of the five-channel audio tape recorder are synchronized from the VCR / 12 - see figure 5 /.

The above methods for generating pulse-code signals that carry information about the coordinates of the primary points of sound emitters, their amplitudes of sound and directional angles of the horns of sound emitters, provide high accuracy in determining the primary points of sound emitters on the transmitting side, high accuracy of reproduction of these points in the cells of sound emitters at the receiving side and therefore high quality stereo effect.

The reality of the implementation of the proposed stereo method follows from the following: the above signals N _x 1-4, A _n 1-4; α _{x, y} 1-4; U _SL 1-4 are allocated in the stereo receiver in units of 24, 25, 26, 27, 28 / cm. 5 / and are divorced into the corresponding blocks of matrices 1-4 of the signal channels of the audio frequency and the matrix block of the code channel. The values of the numbers n1,2 for each matrix are allocated in the converter N _x → n1,2 / 26 - see figure 5 /, the signal selector n1,2 1-4 / 27 - see figure 5 / and correspond to the code numbers defining in blocks of horizontal and vertical rows / 7, 8, 14, 15 - see figure 5 / of the above matrix blocks, the on-time and the number of the cell switching sound emitter, to the inputs 3, 4 of which are fed through the blocks of the matrices: II-1-II- 4 sound frequency signals U _SL 1-4; the switching pulse of the sound emitter cell and the code values of the directivity angles of the horns of sound sources α _{x, y} 1-4 are fed through the matrix block of the code channel I to the input 1, 2 of the above sound emitter cell.

Because each block of matrices II-1-II-4 corresponds to one signal channel of sound frequency, which can be connected at different switching times in accordance with the transmitted code-side pulse code signals to a given number, for example 100, of cells of sound emitters on the receiving side, it is possible switching n cells of sound emitters / n = 100 / or switching / switching on / these cells to four high-quality sound channels at a time specified by the code signal.

The code number α _{x, y} 1-4 is set in the cells of the sound emitters using blocks 4, 5, 6 / cm. figure 5 /, which is fed through the code matrix I: modulator / 11 - see figure 5 /, the block of vertical rows / 11 - see figure 5 / to the corresponding coordinate code N _x 1-4 cell number of the sound emitter. The analog value of the code number A _n 1-4 is fed to the matrix II-1-II-4 modulator / 18 - see figure 5 /, the block of vertical rows / 15 - see figure 5 / from the digital-to-analog converter / 27 - see figure 5 /. Code number A _n 1-4 determines the amplitude of the sound of the audio frequency signals U _SL 1-4, transmitted to the corresponding coordinate code N _x 1-4 cell number of the sound emitter.

Thus, the reality of the implementation of the proposed method of stereo is to reproduce the nth number of sound sources on the receiving side that carry information about their spatial location, which is unique when implementing the device according to the above method of stereo.

5. The ability to carry out actions; the unambiguous coincidence of the points of the sound emitters shown on the television projection screen or movie screen and determined by the listener's eyes, and the points of the same sound sources determined by the listener's hearing aid / binaural effect /, is real in the device for implementing the proposed stereo method / cm. figure 5 /. In this case, the above stereo receiver and, for example, a projection television receiver are projected, which projects a television image onto a 10-20 m ² screen, receiving television image signals from a VCR / 12 - see FIG. 5 / and stereo audio signals from a five-channel audio tape recorder / 13 - see figure 5 /, synchronized from the above video recorder. In addition, it is possible to broadcast over the air from a telecentre, in which the television image signals are synchronized with stereo sound signals received by the projection television receiver and receiver for implementing the proposed method of stereo. Thus, there is a relationship between the television image on the projection screen of the television receiver and the synchronous sound signals of the stereo receiver: for example, the singer’s mouth opens and closes in time with the sound signals played by the singer. With a large area of the television projection screen, it is possible to place a large number of sound emitter cells behind the screen that are part of the stereo receiver, which can be turned on / off / at almost any point in the area occupied by the projection screen. For example, if the images of frames with the singer are being transmitted in television, the sound source in accordance with the pulse-code signals of the transmitting side will be turned on at the point on the television screen where the singer’s mouth is located. Thus, the listener will observe the coincidence on point TV of the projection screen of point 1 - the image of the sound emitter / singer’s mouth /, defined by his eyes, and the point of the sound emitter, which is the switching point of the sound emitter cell, located at point 2 behind the television screen where the singer’s mouth, the listener determines the above point 2 with his hearing aid. Point 1 matches point 2 on a television screen for a listener watching and listening to a television broadcast with stereo audio. Unambiguous coincidence of these points with high accuracy is possible with high quality stereo effect. The same is true provided that the pulse-code signals are transmitted: N _x 1-4, A _n 1-4, α _{x, y} 1-4 by the transmitting side in accordance with the design of the receiving device, in particular, taking into account the geometric arrangement of the cells of the receiving sound emitters devices behind a television projection screen.

6. Implementation of actions leading to the feasibility of the feature: "high quality stereo effect is achieved due to the interdependence of the signal channels of the audio frequency with a large transitional attenuation between the channels, the absence of crosstalk between the channels and phase distortion in the channels when determining the points of sound emitters without strict identity requirements channels. " consist in the following: in the proposed device, the stereophony of the four signal channels of the audio frequency do not affect each other, because The sound frequency channels in the transmitting and receiving units are isolated from each other by filters with large attenuation of frequencies outside the filter transparency interval: attenuation is greater than or equal to 60-80 dB, which leads to almost absolute independence of the filtered sound frequency channels. When connecting the nth number of cells of sound emitters at a certain point in time to each of the four signal channels of the sound frequency in the stereo receiver, there is no violation of the independence of the sound frequency channels, because in blocks of matrices 1-4 of the signal channels of the audio frequency, the channels of audio frequency are decoupled by diodes, which give a large attenuation of these channels from each other when switching blocks of vertical and horizontal rows in the above matrices.

When stereophony is implemented in a system with polar modulation, there is an interdependence of two audio frequency channels: if these channels are identical, there are deviations of the geometric location of the points of the sound sources reproduced by the stereo receiver from the primary points of the sound emitters in the studio at a 1: 1 scale of the premises where the sound sources are located on the transmitting and the receiving side.

When implementing the device according to the proposed stereo method, the accuracy of reproducing the points of sound sources in the space of the receiving device does not depend on the parameters of the signal channels of the audio frequency, but depends only on the accuracy of determining the primary points of the sound emitters on the transmitting side during normalization of pulse-code signals and on the accuracy of reproduction at the receiving side of the corresponding points of sound emission in accordance with the above pulse code signals. In each channel, sound frequencies can be reproduced with their own characteristics, as there is no dependence of the accuracy of reproduction of the points of sound emission in the receiving device on the identity of the channels. When implementing the device according to the proposed stereo method, one-time dependencies between the signal channels of sound frequency are not assumed when determining the points of sound emitters on the transmitting and receiving sides, but there is a synchronously time-dependent dependence of the time of switching on the cells of sound emitters on the receiving side on the time of "turning on" the primary points of sound emitters on transmitting side. In this case, pulse-code signals containing information on the spatial arrangement of the primary points of the sound emitters are transmitted in the narrowband code channel.

The provision in the proposed device stereo of interdependence of the signal channels of the audio frequency leads to the implementation of actions leading to the implementation of the sign; "the absence of interference phenomena from n sound emitters." Reproduced sound signals from n sound emitters in this case create a natural perception of these signals similar to n primary points of sound emitters in a studio.

7. The proposed stereo method can be implemented in currently existing analog or digital television channels by using one existing high-quality FM sound channel in an analog television channel with an audio frequency bandwidth Δ f = 16-20 kHz and introducing an additional single narrow-band pulse -code channel with a frequency bandwidth Δ f = 1-10 kHz in the protective zone of the television channel Δ f = 0.125 MHz.

The generated pulse-code signal N _x 1-4, A _n 1-4; α _{x, y} 1-4 starts from the automatic identifiers of the codes / 19, 20, 21 - see Fig. 5 / to the pre-amplifier of the telecentre / 22 - see Fig. 5 / together with the sound frequency signals U _sl 1-4 and through the transmitter of the telecentre / 23 - see figure 5 /, after modulation of a high frequency of the order of 7, 9 MHz, is transmitted to the air at the frequency of the television channel. The signals of the transmitter of the telecentre are perceived by the receiver of the stereo and the receiver of television signals.

Signals the audio frequency of the FM channel of the sound channel of the television channel are entered onto the matrix block of the 1st signal channel of the audio frequency, which commutes these signals in accordance with the pulse-code signals of the narrow-band code channel to a given number of cells of sound emitters of the receiving side and sets the amplitude of sound signals sound frequency of the above cells. The blocks of matrices II-2-II-4 of the signal channels of the audio frequency are not involved. The signals of the pulse-code channel are entered onto the matrix block of the code channel I, which enable / disable / the cells of the sound emitters and set the directivity angles of the horns of the sound sources. The above signals pass through blocks 24, 25, 26, 27, 28 / cm. 5 / stereo receiving device to respective matrix blocks.

Thus, the signals of one signal channel of the audio frequency are reproduced in the stereo receiver at different geometric points in the location of the receiving device in accordance with the pulse-code signals of the transmitting side. The above playback points of the audio signal channel correspond to the primary points of the sound emitters located in the television studio of the transmitting side. At the same time, stereo audio signals with high stereo quality are reproduced in the receiving device during a solo performance at each moment of time, and when several sources of sound are heard in the studio of the transmitting side at the same time, the pulse-code signals of the transmitting side carrying information about the corresponding number of sounding points of sound emitters located in different coordinates and reproduced in the cells of sound emitters of the receiving side us with varying amplitude sound.

8. Method and means of implementing the feature: "densification by high-frequency pulses was applied, the time of turning on the nth number of signal channels of sound frequency using the nth number of independent matrices with decoupling diodes for the number of emitters emitted at the same time in each channel at the same time with different amplitudes sound, the inputs of which it is possible to send signals, leading to the possibility of implementing the method of stereo with movement in the perception space of listeners of sound sources in accordance with the pulse code signals of the primary points of sound emitters "- consist of the following: each n-th matrix of the audio signal signal channel compresses one audio frequency channel: at one time of a given interval of sounding of sound sources, it is possible to include from the total number of N cells of sound emitters existing in the stereo receiver , any four cells sounding with different amplitudes in accordance with the pulse-code signals A _n 1-4, which in the digital-to-analog converter / 27 - see Fig. 5 / are converted to an analog value and wound up in the corresponding matrix of the signal channel of the audio frequency to the input of the modulator / 18 - see figure 5 /. The required amplitude of the sound of the sound signals of the channel is set in accordance with the above analogue value at the time of switching on the Ni cell of the sound emitter in accordance with the pulse-code signals of the coordinates of the primary points of the sound emitters on the transmitting side N _x 1-4.

Each matrix of signal channels of sound frequency from the total number of n matrices includes cells of sound emitters in the time interval determined by the generator 300 kHz / 17 - see figure 5 /, including the above cells using blocks of horizontal and vertical rows / 14, 15 - see 5 / pulses with a repetition rate of 300 kHz and the corresponding duration. Thus, the high-frequency pulses are compressed to turn on the corresponding sound frequency channel included in the input of the corresponding block of the matrix of the signal channel of the sound frequency, into four cells of sound emitters, sounding simultaneously with different sound amplitudes. The coordinates of the inclusion of the cells of sound emitters can change after a given period of time, i.e. sound sources are turned on at different geometric points in the room where the stereo receiver is located or move from one point in space to another in accordance with the pulse-code signals of the primary points of the sound emitters located, for example, in the television studio on the transmitting side.

Information on the formation of pulse-code signals N _x 1-4, A _n 1-4, α _{x, y} 1-4 are given above.

9. The concept: "to reproduce the signal power corresponding to the true sound source with z _x sounding sound emitters simultaneously" in one or four channels of sound frequency, involves limiting the total power of the signals of four sounding sound emitters simultaneously in one channel of sound frequency or limiting the total power of signals 16 sounding sound emitters simultaneously in four channels of sound frequency.

To limit the above total power of the signals of the sound emitters, the gain adjustment of the sound signals of each of z _x sound sources is applied in accordance with the transmitted side of the pulse-code signals A _n 1-4. The setting of a certain power level of the sound signals of each sound source occurs, for example, in the television center studio on the remote control of the sound engineer by the personnel serving this remote control. In this case, it is possible to limit the total power z _{x of the} sound emitters. The need to limit the radiation power of simultaneously sounding, for example, 16 sound emitters / maximum radiation power of one sound emitter P _1max = 1-3 W / is obvious, because in case of random errors of the sound engineer, malfunctions of the transmitting and receiving equipment, etc. radiation of the total sound power from 16 sound emitters, greater than or equal to 16 watts, is possible. The above circumstance is important when operating the stereo receiver in the apartment of a house with poor sound insulation.

The control of a given level of the total power z _{x of the} sound emitters in the stereo receiver takes place in the pre-amplifier of the telecentre / 22 - see figure 5 / and the television receiver / 24 - see figure 5 / as follows: sound frequency signals from the maximum number of emitter cells sound existing in the stereo receiver, are wound up on the adder with a threshold automatic gain control, included in the television receiver. When the total power of the switched-on cells of sound emitters is greater than or equal to 0.1-1 W / the required total radiation power of the cells of sound emitters of the receiving device, the stereo is set by the listener using the volume control /, a signal appears from the threshold automatic gain control, which reduces the total radiation power of sound signals, acting on the block 24, or turns off the stereo receiver using a threshold device.
