Description

The invention relates to radio communications technology and can be used for digital stereo broadcasting.

The prototype is a “stereo television system” [1], containing on the transmitting side a photoelectric converter / photovoltaic converter /, which is a sensor of video signals of three basic colors B, G, R of the right frame and three colors B ₂ , G ₂ , R _{2 of the} left frame, and includes the first a lens and a first image receiver, a second lens and a second image receiver, each of the image receivers includes a matrix of 10 ⁶ elements / 1000 × 1000 /. The transmitting side includes identical first to third channels for processing the video signals of the right frame and identical fourth to sixth channels for processing the codes of the left frame. The channels for processing the codes are made identically from the series-connected signal extractor of the high-order code, register block, and encoder. The transmitting side includes a code stream shaper, first and second pulse distributors, a frequency synthesizer, a first self-propelled pulse distributor / SRI /, second SRI, the first and second sound code processing channels, five-digit codes of which arrive at the third and fourth information inputs of the code stream shaper. The first SRI gives the synchronization code of the SSI line of five bits, the second SRI gives the synchronization code of the CSI frame. The transmitting side includes a radio signal transmitter from a carrier frequency amplifier, an amplitude modulator and an output amplifier connected in series. The image of the lens is projected onto the receiving surface of the image receivers. Each element of the matrix is a "radiation brightness - code" converter and includes an opaque case, in the input end of which there is an opaque microfilter, attached to the free end of its micropiezoelectric element, the second end of which is fixed in the element case and connected to the output of the pulse distributor through a diode. Behind the microlens and along its optical axis there are three color micro-light filters of colors R, G, B, each of which is attached to the free end of its micro-piezoelectric element. Eight translucent micromirrors are located behind the color filter along the optical axis along the number of bits in the code, and eight photodetectors are located on the side of the casing to which the micromirrors are turned, which receive radiation reflected from the micromirrors and give out pulses to the pulse amplifiers. Each converter is serviced by eight pulse amplifiers and nine keys and is a functional part, which are in the block by the number of elements / converters / in the matrix 10 ⁶ . At the end of the frame period, 10 ⁶ color codes R, G, B and R ₂ , G ₂ B ₂ representing the digitized right and left frames of the stereo pair are received from the functional parts in the register blocks. Codes of video signals of colors R, G, B are formed one after another sequentially in a frame after 13 ms each. For a frame period of 40 ms, in all matrix elements, the conversion "exposure brightness - code" is converted sequentially after 13 ms. The register blocks are identical, each contains 10 ⁶ eight-bit registers from which the video signal codes are sent to encoders that re-encode the high-order signal in the code into binary code and four-bit codes representing the number of the bit in which the high-order signal was located are followed by the encoder output code in eight-bit code. And four-digit codes come already in the shaper of the stream of codes, which are transmitted on the air. The receiving side receives the codes, in the channels of processing the video signal codes, four-digit codes are translated into eight-digit codes and are output to the inputs of the right and left screens, the images from which the viewer perceives three-dimensional through glasses of separate fields of view.

The disadvantages of the prototype are:

1. on the transmitting side, color codes are generated not in parallel, but sequentially after 13 ms, and each converter, when generating three-color codes, works three times in succession for 13 ms.

2. The codes are transmitted from the converters of the image receiver through the connections for the right frame 3 × / 8 × 10 ⁶ / and the left frame through the same connections 3 × / 8 × 10 ⁶ / to the register blocks.

3. On the receiving side, the image formation on the screens is performed by sequentially triple flashing 13 ms of image separately for each color R, G, B, the color image of the viewer is formed by the overlay of three images separately, each for 13 ms on the retina.

The purpose of the invention is to obtain synchronous flashing on the screen simultaneously of three colors and to reduce the number of connections from the image receiver to the register blocks by half from 2/3 × 8 × 10 ⁶ / to 2/3 × 4 × 10 ⁶ / and to exclude connections from the register blocks to encoders and from them to the code stream shaper.

The technical results are on the transmitting side the use as elements of the matrix of converters "the brightness of the colors R, G, B - three codes" synchronously forming three codes of three colors, replacing the channels for processing sound codes with two sound-code converters, which is a digital microphone, on the receiving side, receiving pixels on screens with the simultaneous participation of three colors simultaneously.

Screens 86, 98 with a resolution of 10 ^{6 are} made identically, the matrix of each screen of the elements 1000 × 1000 respectively resolution. The elements in the matrix are miniature radiating cells, Fig. 17, each includes an opaque housing 135, in front of which the lens 136 is mounted on the irradiation side, three color microfilter 137, 138, 139 of three basic colors B, G, R are arranged in series, mounted on their micropiezoelectric elements 141, 142, 143, a damper 140 is located in the outlet end of the housing, which in the closed position blocks the radiation output from the emitting cell. Each color filter and shutter are attached to the free ends of their micro-piezoelectric elements 141, 142, 143 and 144, the second ends of which are fixed in the element body 135. A color pixel is obtained on the screen by introducing three color filters synchronously into the radiation flux for the duration of their control pulses. The color filter is introduced for the duration of the control pulse from its pulse amplifier, and all three control pulses pass through the diodes D1-D3 to the control input of the micro-piezoelectric element 144, so the shutter is open for the duration of the longest control pulse. With the arrival of the control pulse to the input of the micropiezoelectric element 141, 142, 143 and 144, each of them performs a bend with rotation, which introduces the light filter and damper mounted on it into the working position in the irradiation stream. The color of the pixel is the result of mixing colors B, G, R at the moments of their joint presence in the irradiation stream. The irradiating cells are irradiated with white-emitting diodes located in the corresponding quantity and in the corresponding order inside the screen cases on their back sides. The SSI isolation block 100 and the CSI isolation block 105 are made identically, each of which includes / FIG. 14/ a three-digit pulse counter 125, a decoder 126, an element HE 127 and two diodes D1 and D2. The counter 125 counts five pulses in a row 11111 code SSI / KSI /. The information input of the block 100/105 / is the counting input of the counter 125 connected to the output of the shaper 73/74 / pulses, the control input is the input of the diode D1, its output is connected to the control input U _{about the} counter 125, the input of the diode D1 is connected to the output of the pulse shaper 74 / a in block 105 to the input of block 73 /, the first and third outputs of the counter 125 are connected to the inputs of the decoder 126, the output of which is the output of the block 100/105 / and is also connected through the diode D2 to the output of the element NOT 127, and together they are connected after D1 U to a control input _of counter 125. to d FID / CSI / five units in a row 11111 is fed to the count input of the counter 125, and outputs it appears code 101 which decoded the decoder 126 to the output of block 100/105 / receive pulse, which pulse FID / CSI /. When the SSI code is in, the CSI code is not in, and vice versa / Fig.2/. Starting from the second code of the line, from the block 73 to the counting input of the counter 125 there are video signal codes, and since in 8-bit codes there is only one pulse, and in the remaining zeros, the element NOT 127 will give a pulse to the input U _{about the} counter, which will be zero, and at the output of counter 125 there will be no code 101. The D1 will also receive codes from block 74, in which there is also one pulse, the remaining zeros that will reset counter 125, five units in a row are also not dialed in sound codes, and only with the receipt of the SSI or CSI code does counter 125 give out code 101, at which e unit 100/105 / receive an output signal indicating that a code FID / CSI /, the same pulse through the diode D2 is supplied to the control input Uo counter 125 and resets it, preparing it for the next operation. The circuit blocks 100, 105 exclude the appearance of false pulses SSI / CSI / at the output. Flat panel screens 86, 98 are identical, each of them includes miniature radiating cells as an element of the matrix, each of which independently forms a color pixel from three colors B, G, R, which creates conditions for increasing the resolution of flat panel screens.

The work of the transmitting side.

Reading of codes of video signals is carried out by image receivers 2 and 8, as elements in which converters are used "radiation of colors R, G, B - three codes", each issuing synchronously three eight-bit color codes R, G, B and R ₂ G ₂ B ₂ , image receivers 2, 8, eight-bit codes are also re-encoded, as a result, three streams of codes of three colors, each of 4 × 10 ⁶ , coming to the information inputs of 4 × 10 ⁶ blocks 4, 5, 6, follow from the outputs of the image receivers 9, 10, 11 registers, the outputs of which are video signal codes The signals are sent to the first and second information groups of the inputs of the shaper 12 of the code stream, to the 3 and 4 information inputs of which are received in parallel five-bit codes from two sound-code converters. Formed by the block 12, the code stream (Fig. 2/) enters the transmitter 15 of the radio signals and is broadcast.

The work of the receiving side.

Radio signals are received by block 70, which is an electronically tuned channel selector, to the third input of which a frequency synthesizer 101 receives a frequency equal to the carrier frequency of the transmitter 15 / Fig. 1/, necessary for detecting a single-band signal / 8 p.146 /. The signal from the mixer, which is the output signal of block 70, enters the radio frequency amplifier 71, is amplified, and fed to the input of a bipolar amplitude detector 72, made according to the scheme in Fig. 9. Diode D1 selects the envelope of the modulating signal / Diagram 9 in Fig. 18 /. Diode D2 from the modulating one selects the envelopes of positive half-sine waves / symbols of units of codes of the right frame /, diagram. 10 Fig. 18. The diode D3 from the modulating one selects the envelopes of the negative half-sine waves / symbols of units of codes of the left frame / diagram 11 of Fig. 18 /. From the first output of block 72, the detected positive half-sine waves of 375 MHz are fed to the input of the first pulse shaper 73, and from the second output of block 72, the detected negative half-sine waves are fed to the input of the second pulse shaper 74. Shapers 73, 74 form rectangular pulses from harmonically changing signals, units in the codes are represented by pulses, zeros by their absence. The order of operation of the receiving side is set by the signals of the channel for generating control signals: the first role belongs to block 100 SSI / code 11111 /. Each time the SSI code block 100 arrives at the input, a horizontal SSI clock pulse of 25 kHz appears at its output, which opens the key 102, and the fine tuning of the frequency in the 101 frequency synthesizer proceeds from the SSI signals, its own stability is 10 ^-6 . From the output of the first driver 73 pulses, the codes are fed to the input of the first key 75, which is closed in the initial state, opened by the SSI pulse through the diode D1 / 10 /, and at the beginning of the frame opens through the second diode D2 from block 105. From the outputs of the driver 74 pulses codes of video signals are fed to the input of the second key 87, which in the initial state is closed, opens together with the key 75 signal SSI or CSI. The codes of the right frame are bitwise and sequentially received in the first to twelfth bits in the first receiving register 76, the codes of the left frame are transmitted in the first to twelfth bits of the second receiving register 88, three four-bit codes of video signals are placed in each receiving register. The second inputs of the frequency synthesizer 101 are connected to the second group of outputs of block 69, the signal from which sets the frequency output from block 101 to the third input of block 70. The frequency synthesizer produces: from the first output, 25 MHz pulses of the sampling frequency of the video signals, from the second output, clock pulses 375 MHz, from the third output pulses of 75 kHz frequencies of sound codes, from the fourth - sinusoidal oscillations of the carrier frequency to the third input of block 70. From the output of the first driver 73 pulses, three codes of video signals of the right frame B, G, R are filled in the receiving reg Streit 76 code bits 1-4 colors R, 5-8 bits of color code G, 9-12 bits of color code B. The same procedure of filling bits in register 88 receiving the codes of the second / left / frame. From the receiving registers 76, 88, the codes are synchronously issued by 25 MHz signals to the decoders 77, 80, 83, 89, 92, 95, respectively, which decode the four-digit codes from their outputs to the drives 78, 81, 84, 90, 93, 96 codes 8-bit codes are already received in the frame, in which the pulse is in only one of the eight digits. During the period of 40 ms frame is the concentration of the codes of both frames in the drive code frames. At the end of the frame period, the codes of both frames are synchronously issued in parallel in the form of U _output 25 Hz signals into their pulse train 79, 82, 85, 91, 94, 97 in terms of duration and amplitude. The duration of the pulses in each code from the outputs of these blocks corresponds to table 3, they are now control signals and are fed to the control inputs of the micro-piezoelectric elements 141, 142, 143, respectively, in all the emitting cells 135 of both screens 86, 98 Ufig. 10 and 17 /. Playable video mode: 1000 × 1000 × 25 Hz, there is no horizontal and vertical scanning.

Filling the registers with the codes of the first line begins with the opening of the key 121 with a 25 Hz signal from block 105. The public key 121 passes pulses U _D 25 MHz to the input of the pulse distributor 123, the clock pulses from which are sequentially fed to the first, clock, inputs of the bits of eight registers 124. the register from the last 1000th output of block 123 closes the key 121 and opens the key 121 in the next block _{2 of 2} registers, the registers 124 of which are filled with the codes of the second line. For a frame period of 40 ms, registers 124 _1-8 are filled in with codes in all blocks of 120 _1-1000 registers. From the last block 120 _{1000 of} Fig. 11, the output signal is sent in parallel to the fourth control inputs of all blocks of 120 registers and opens in them the second keys 122, passing one signal U _OUT 25 Hz, synchronously issuing from all blocks of registers 120 _1-1000 and all drives frame codes codes of video signals to their respective blocks 79, 82, 85, 91, 94, 97 of the pulse shapers in duration and amplitude. Each drive of frame codes has 8 × 10 ⁶ outputs that are connected to the same number of inputs in the pulse shaper blocks in duration and amplitude.

The signal inputs of the keys 128 _{1-3 are} combined and are the second control input of the register unit 107, 114.
