The specified system is used for facsimile and electronic communications, the image memory stores encoded image data, the printer is designed to print data in the form of images (US 4805135 A, 14.02.89, H 04 N 1/04),

Known systems for information exchange of data, storage and retrieval of information in a computer network, in which data over the network is moved in digital form.

Movable data on the receiving side is restored, converted by decoding and processing into data in the form of images, images can also be recorded on optical discs (US 4817050 A, 03/28/89, G About K 9/00).

A known system and method for transmitting text and graphic information between a computer and a remote display terminal. The system contains information input-output blocks connected to the processor, random access memory, control unit, interconnected via system buses. The system is designed to store, display, print and otherwise manipulate the stored color image, while the system provides encoding of the information received at the image input and decoding the image into a code signal transmitted via a communication channel to a remote terminal. The processor of the system is connected to the memory, modem, graphic card connected to the monitor. The remote display terminal comprises a processor associated with a modem designed to interface with the communication channel on one side

and with memory or with a means of recording to disk on the other hand (US 5235680 A, 08/10/93, G 06 F 15/00).

Known systems do not allow to coordinate the input and output data streams of external devices connected to information and / or computer systems by simple means.

Known systems due to complex conversions of some formats to others have the property of losing some of the information, or the implementation of such transformations requires a lot of redundant information.

Closest to the technical nature of the claimed system of transmitting information with compression of communication channels is an information transmission system with compression of channels containing transmitting and receiving parts. The input signals of the system are the signals of sound programs and digital data signals that are converted in codecs, for example, are encoded by an MPEG encoder to compress digital audio data. Further, all individual digital streams from all channels arriving at the inputs of the system are multiplexed by the control unit into a combined digital stream, which enters the modulator and further into the communication channel. When receiving carry out the inverse transformation. The incoming signals are demodulated in a demodulator, demultiplexed by a control unit and each is sent to its own decoding unit (codec), after which it is subjected to digital-to-analog conversion and transmitted to the corresponding signal receiver (see Kovalgin, Broadcasting and

electroacoustics, M., Radio and communications, 1999 (signed for publication on 10/29/98), pp. 723-724).

The known system does not allow transmitting signals of television channels of different standards and different resolutions on a single communication channel.

The closest in technical essence information transmission system in a telecommunication network is an information transmission system over a communication network, containing servers connected through communication nodes and modems to client computers. The system is designed to transmit information over the network, including upon request. Modems (modulators and demodulators) are associated with transmission channels, the transceiver equipment included in the system is designed to convert network signals into signals for reception and transmission (I. Norenkov et al. Telecommunication technologies and networks, A, Izmail MSTU them.N.E.Bauman, 1998, S. 31-32, 60-61, 87).

Known systems do not allow to increase the number of serviced requests using known telecommunication networks, i.e. networks have significant customer service restrictions.

In known systems for transmitting, encoding and / or decoding information, the image itself is. In the claimed systems, the message: information data streams, sound information and visual, visualized by representing all messages in the form of raster data

In other words, all known information coding and decoding systems do not use presentation methods. . messages of audio, text, graphic and information recorded on information carriers and encoded with binary symbols, raster (point) data arrays of color space such as RGB, CMY, YUV, LAB, etc., i.e. using digital television coding methods (RE Bykov, The Theoretical Foundations of Television, St. Petersburg, Lan, 1998, p. 52, 56; Blanter D. et al. Scanning and Rasterization of Images, M., Iz- in ECOM, 1999, p. 50). The claimed systems, in contrast to the known systems, use, as a representation of the information entering the system in a very different way, the conversion of information into code sequences of data in raster color space files, which allows to obtain the following technical results. The technical result of the claimed systems for encoding and / or decoding information, a data transmission system with channel multiplexing, and an information transmission system in a telecommunication network is to provide a message (text, sound, graphic, digital, analog information) in the form of code sequences of coordinates of color space points intended for recording, storage, conversion, reading and transmission of information with the aim of using them in appropriate information systems themes. This extends the arsenal of means of encoding and decoding information and allows you to visualize information in the form of graphic images using well-known means of reproduction (video monitors and

etc.) / use as a storage medium its printed image in the form of an array of raster point data. The systems allow such messages to be transmitted over communication channels, including telecommunication channels with a high compression. The technical result of the claimed group of systems is the conversion of input signals from practically any message sources (audio, text, bit, graphic information) into a universal unified form of information representation, namely, into code sequences of coordinates describing color space points, for example, R, G planes, B. This makes compatible both processor systems and television systems designed to process, analyze and present and / or reproduce information, providing A wide range of external devices is connected to the system.

The technical result of the claimed systems is also the ability to visualize the sound and / or stream of digital signals in the form of a color image, such visualization of information allows you to expand the arsenal of tools for analysis and / or synthesis of the characteristics of signals and / or states and / or other characteristics of directly information sources using visual, graphical and statistical analysis tools.

Converting sound images (for example, musical ones) into graphic images and / or graphic images into sound ones can make it possible to synthesize visual and sound means for various purposes, including in show business.

Using the proposed information encoding system allows you to create a cryptographic encryption system, because without information about the service information (format) when visualizing information in the decoding process, it is almost impossible to restore the original message. It is advisable to use this property when creating protective elements of money, securities, documents, secret signatures, etc.

In addition, the use of the proposed information conversion allows you to visualize the messages presented in the claimed way by high-precision photo printing, i.e. high-resolution photo printing.

The use of such systems in printing can significantly reduce the volume of printed documents, i.e. save paper media / in this case message visualization, i.e. their perception by a person can also be carried out using one of the options for implementing the system.

The proposed systems allow, as mentioned above, to transmit messages using various television channels of information, as well as telecommunication networks, including the Internet, which allows to increase the number of served requests on the network. The prerequisites for the creation of the claimed systems is that the description and presentation of images, as indicated above, can be made on the basis of color models such as RGB, him, YUV, etc., in which a point can be described by a number (code) value for each of the coordinates used, for example, in the planes "R," G, "B. The set of points forms an image presented in a raster form in

color space, resolution, i.e. the number of horizontal and vertical dots of the image field, for example, for monitors is 640x480 and 800x600. In this case, the quantity of quantization steps in terms of the amplitude of the three color components R, G, B should be added to this value. With an eight-bit representation of message words, one can obtain the message volume

640x480x3x8 7.272.000 (bits) or 800x600x3x8 11.520.000 (bits) for each image field. With the field frequency in the signal equal to 25 fields / sec, this will amount to 7.372 Mbitx25 fields / sec 184.3 Mbit / sec or more. This calculation is given to represent the values of the possible data rates, as well as their volume 7.372x25 184.3 (Mbps) 11.520x25 188 (Mbps).

Thus, the use of the presentation of information by raster data will ensure the compatibility of computing systems, digital television, scanning, printing, and visual presentation tools.

To explain the formation of data in the 36i or Zb2 memory subzones, we note how each raster data point is represented in color coordinates, respectively R (red), G (green), B (blue), A (black and white) color planes.

To do this, imagine that any point n of raster data can be described as, bY, cZ, tK, where X, Y, Z ... K - (1) color planes, for example, R, G, B, A, and , B, c, ... t is the value of the coordinates in the planes of the color space X, Y, Z ... K.

For each point in the sequence of points during coding, we give the length of the values a, b, ev of each color plane in the form of the number of bits allocated to it, for example, respectively, in the planes: R, G, B, A for formats: GIF, 320X240 2-2- 2-2

for formats: TIF, 640X480 3-3-2-0 (2)

The claimed system implements the conversion of input information into the coordinates of the raster points and further into graphic formats of raster data. Moreover, the data (information) flow in the general case is a sequence of data elements packed in the form of a sequence of words having sizes different from the sizes of data elements of a raster file.

Data in information systems, including those that enter the claimed encoding and / or decoding systems, have a certain structure. Formally, a data structure is defined as some well-defined area in the abstract data type that defines this structure. The data format is a certain structure of the information object being processed, recorded on a medium, displayed on a display, printed on paper, i.e. the format indicates actions, for example, recording information in a prescribed form or dividing the storage medium into sectors or zones. The format is defined using headers; headers in these systems define standard options.

The flow of information structured in the form of a format and not structured is fed to the input of the system, i.e. to block 1 input information.

The input unit 1 transfers this data to RAM 3. In accordance with the specified format, which can be specified by entering format data from the keyboard 51 of the control unit 2, or defined by the system, the system must present the data in such a way that the input information stream at the system output has been paired with an external device.

Consider a simple example, when the format is set from the keyboard 51 (figure 2), consider the operation of the encoding system and the encoding and decoding system.

The system, according to purpose, operates in an encoding mode of information (Fig. 1, Fig. 2 and Fig. 5).

The input data stream, including unstructured data, i.e. without format, it enters through the data input unit 1 in RAM 3, where it is stored for the duration of processing in the system.

In this case, for simplicity of description, a command is issued to the control unit (element 38) via the keyboard 51 for implementing the encoding mode. In addition, data on the format of the external output device (bus specification) is entered into the control unit using the same keyboard, according to which the input information should be converted. The coding start signal also comes from the keyboard to all elements 38-43 of the control unit 2. Next, through the element 38, a mode selection signal is input to A14, a data zone or a zone of header words is selected

39f 24

(Fig. 2.5, input A13 element 39). In this case, suppose that the selected memory zone 35i words header Zi-Ze (figure 5).

Next, the Zi-Ze headers themselves are selected by applying selection signals from the encoder 14 to the inputs A10-A12 via the element 40 of block 2. These signals correspond to the desired header, the data about which are received from the keyboard 51 to the element 40.

The procedure for transferring the selected header Z from zone 35 of the memory unit 15 to the output unit 11 is carried out by applying counting pulses to the input of the counter 12 from the control unit (element 41), while the binary code at the output of the counter controls enumeration of addresses A2-A9 (Fig. 5) containing words that make up the selected header from the zone 35i of the memory block.

Then the counter is turned off. The number of words displayed from the memory can be increased by adding to the output words a simple combination added by the signals from the outputs of the encoder 13. This procedure corresponds to the selection of additional sequences of data words. Next, the output of the informational message arriving at the system from the data input unit 1 is carried out. To this end, a signal is inputted at input A13 to switch from the header area 35 to the data area 36, i.e. to data selection mode. Then, signals are sent to the address inputs of the selection of the data words themselves, i.e. inputs A10-A12 for selecting the corresponding subzone Dx-D with the heading Dv from zone 36i. To do this, 8-bit words of the entered data are transferred to the register 21 from the RAM 3.

Depending on the selected format, the keypad 51 sets the sequence for reading data from the selected subzone 36i D by controlling the inputs of AO-A1. This is due to the fact that reading can be different for different formats. For example, it can be sequentially along the planes, first all the values of the plane R, then G, then B or line by line, but in a known standard manner, prescribed format.

The selection of the raster words themselves color planes (2) from the selected subzone D is as follows. Data from the register 21 is supplied to the corresponding inputs A2-A9 (the counter does not work) for control from element 42 of block 2. Depending on this data, the corresponding words are selected from the indicated subzone D according to the correspondence table (Fig. 5, 36i). Thus, at the output of the memory block, a predetermined raster data structure is formed, the format of which corresponds to the format of the external device. At the output of the output unit 11, the data is represented by graphic raster data formats.

Decoding mode coding and decoding systems and decoding systems are implemented as follows.

For the case when the systems decode the data stream of the format of an external device connected to the input of the corresponding system into the format of an external device connected to the output of the system, the operation does not differ from the system in the encoding mode described above. The difference is that the memory zones Zbg and Zba of data are used in the decoding mode selected at the input A14 by the control unit 2.

A signal is input at input A14 for decoding mode selection and a format is input for generating output data from keyboard 51.

Further, the decoding process proceeds in the same sequence / as in the encoding mode.

In the case of the decoding mode of graphic formats of raster data, for example, data represented by a similar coding system, it is first necessary to select the encoding parameters of the graphic format. If the graphic format does not contain a header (it has not been read by the scanner) or if it is not known in advance, that is, it cannot be entered from the keyboard, then for simplicity, select the raster data header located at the beginning of the raster data in the read data block 1, for example as indicated in FIG. 7.

The case where raster data was printed using a color printing printer connected to the output of the system output unit 11 when encoding data with the declared encoding system, i.e. recorded on the storage medium.

On the printout, dots will be placed line by line according to the encoded data for the field

rendered message. These points can be represented in the color "R," G, "In or black and white A.

Let it be necessary to decode the information printed (presented) in this way.

Figure 7 presents an example of visualized raster data (one line), while the data header can be highlighted, for example, by placing data points printed in the form of a field (or visualized in the upper left corner)

on the dot field monitor) messages of a sequence of 32 points, which is performed in the same way for all graphic files of raster data of the declared encoding systems. The first 8 points are made in the form of a combination of gray (halftone) points, among which dots are highlighted in red (for the R plane) that describe the number and place of significant bits of the R plane (for example, taking into account the distribution of significant bits specified in expression (2) for a given format). Zones can be allocated in another way.

This is followed by 8 points describing the points of the green plane (G) by an appropriate combination of gray and green points.

Next is a combination of 8 bits of gray and blue dots (plane B), the last 8 points are a combination of black and white dots (not shown in the drawing).

After that there are raster data points (not shown in the drawing).

The decoding process in this case occurs as follows (Fig.2 and Fig.6). The scanner reads the image of the message and feeds to the information input unit 1, which transfers data to RAM 3 and to element 48 (Fig. 2) to highlight the standard header of the raster data presented as described above (Fig. 7). In element 48, the incoming data from block 1 (row) and the data of the standard raster header (Dv) are compared, and if they coincide, element 48 sends a signal to the format selection control element 39, after which, from the keyboard 51, commands for decoding and further processing of data as described for the coding system.

Using the keyboard 51, the command is entered into the decoding mode at input A14, the format code Z (header), in other words, the transcoding of an external device connected or potentially connected to the information output unit 11 is carried out. Block 4 is transferred to the decoding mode by applying control signals from block 2 (initiated by the keyboard 51) along line 20 to input A14 of block 15 (Fig. 2).

Then, along line 19, a signal is input to input A13 to select the "data or" headers mode, then, along lines 18, a signal is fed to inputs A10-A12 to select the fli-fle or Zi-Ze subzone. Then, along lines 17, the encoder 13 selects planes for the decoded word R, G, B, A or C, M, Y, K, etc. If the data during the encoding were not divided into separate bytes R, G, B, and the partition was only recorded in the header i.e. described on the demand of the format, then the corresponding subzone (Dg-D) is selected on lines 18. The output data in this case are directly output through register 46. If the data arrives in the form of bytes R, G, B, A, then they are previously collected in register 45 by pushing the significant bits of the individual decoded words from register 46 for control from element 39 of block 2., and then uploaded to the bus of the information output block 11 by signals from elements 42 (Fig. b).

The specified process of shifting the received word into the register 45 is necessary for the bit distribution of significant bits in accordance with the distribution in the eight-bit word of all

components of a, b, c, m color areas (crochet (1) and (2)).

The decoding process itself does not differ from the encoding process described above in coding systems.

The data obtained during the decryption process at the output of the memory block, as indicated above, are collected in the shift registers 45 and 46 into a whole word. At the end of the decryption, the word received in the register 45 is issued to the input of the output unit 11.

The communication channel compression information transmission system comprises (FIG. 3) an MPEG signal codec 22i, an HDTV (high definition television signal) codec 222, a modulator 23, a demodulator 24, bitmap encoding and / or decoding nodes 26, a control unit 25.

The inputs and outputs of the codecs 22i and 222 are connected to the audio and video channels of television and to the audio and video channels of high-definition television (HDTV), the codec 22i and 222 are connected to the inputs of the inputs of the corresponding node 26i - 262 of raster encoding and / or decoding, nodes 26 and codecs 22i and 222 are connected via the control bus 27 to the control unit 25, the control unit 25 is connected to the control inputs of the modulator 23 and the demodulator 24, has an external control input 28i, the outputs and inputs of the nodes 26 are connected respectively to a modulator 23 connected to the communication channel 29 and the demodule torus 24 associated with the communication channel 30. Nodes 26i and 262 are connected to respective codecs 222 and 22i, 26i node may be connected to a data source / for example, the Internet via the bus 282.

./9 30

The information transmission system with the sealing of communication channels (Fig. 3, Fig. 2 and Fig. 5) works as follows.

The nodes of the raster coding and / or decoding 26i - 263 of the claimed system are made in the same way as in the system of encoding and decoding information (Fig. 1, Fig. 2, Fig. 5, Fig. 6) and work the same way as described for the encoding mode and decoding mode.

The data of the television channel and the data of the high-resolution channel (HDTV) are supplied through the corresponding codec 22i (222) to the input of the data input unit 1 of the raster coding and / or decoding unit 26i and / or 262, respectively (FIG. 2, FIG. 3). Data from the network goes to the input unit 1 of the node 26z. The data is overwritten in RAM 3 in each of the nodes 26 and received in the block 4 raster coding, which implements the presentation of this data received, for example, in MPEG or HDTV format, or in the form of a digital stream (node 2bz), in a graphic format of raster data or standard color TV signal data PAL, SECAM ... as described for the encoding mode of the encoding system and the encoding and decoding system. Information about the type of coding mode and the data parameters at the output of the output unit 11 is entered from the keyboard 51 or through the control unit 25 programmatically to the elements 38-43 of the control unit 2 of the nodes 26i - 2 63.

The received raster data from nodes 26i - 2bz in a common graphic file format or a color television signal standard is transmitted in a common stream through a modulator 23 to a communication channel 29. The control unit 25 allocates to each channel

a predetermined message length / or a predetermined number of lines (via bus 27) and reads (control bus 27) from output units 11 of nodes 26 through a modulator to a communication channel. The specified length or the specified number of lines for each channel can also be set by the control signal at input 28i to the control unit. The specified unit 25 can be performed as a control unit 2 in the form of a controller.

The specified conversion allows you to encode television visual and audio messages in the form of certain lines of the raster of the television image, highlighting each television channel a predetermined number of lines of the raster image, i.e. thus unified in this way the data stream is transmitted on one channel, i.e. transmit streams from television channels and from high-resolution channels. Moreover, based on the fact that the information flow rate in a conventional television system is 135 Mb / s, the number of channels that can be placed with a standard television (TV) stream can be determined.

135 Mbps: 1.5 Mbps 90 channels MPEG1, z conventional resolution or

135 Mbps: 15 Mbps 9 high-resolution MPEG1, z channels and, accordingly, any combination of television streams and data streams that have passed through an encoding system containing a raster encoding unit is possible. At the same time, the amount of information that can be placed on one line of a raster image is (720x360) x8x25 216 Kbps, where

32

number 720 - the number of brightness elements per line

number 360 - the number of color elements

number 8 - the number of bits in a word describing brightness and color

number 25 - number of frames

From here the required number of lines of the image raster will be

1.5 Mbps: 216 Kbps - 6.944 “7 lines for conventional TV

1.5 Mbps: 216 Kbps - 69.44 "70 lines for HDTV

It can be seen that the simplest way to allocate channels when they are compressed can be a way to split the lines of a raster of a TV image between different codecs, i.e. allocating a given number of lines to a channel, while additional codecs 22 are connected in the same way as codecs 22i and 222 and they can also be allocated a specified number of lines. At the same time, information on the lines allocated to it is entered into the control unit 25 by the control panel 28i for each node 26. The control unit 25 controls the coding start processor in the nodes 26 and the reading process from the output unit 11 of each node 26 to the modulator. The modulator 23 and the demodulator 24 respectively perform the functions of generating the signals of the transmitter and receiver. The control unit 25, as indicated above, allocates to each channel a predetermined number of lines of the bitmap image, which are transmitted in the same sequence to the modulator 23 and then to the communication channel 29. Thus, the system allows converting all the data received on different television channels into general graphic format or color television standard and read the converted data line by line through the modulator into the communication channel.

The information transmission system can also work in the mode of decompression of channels.

In this case (FIG. 3), the signals of several sources of information (not shown in the drawing) arrive through the demodulator 24 to the inputs of nodes 26 (or node). The control unit 25 at the input 28i receives information about the number of connected sources and the lines allocated to it in the received data stream. The control unit 25 connects a given number of data lines or a message in a predetermined number of bits to the input of the corresponding node 26, the TV channel format is entered from the keyboard, and the block 4 of the corresponding node 26 encodes the message and connects it to the corresponding codec 22i and 222 for conversion and transmission to corresponding television channel.

Thus, in the reverse decompression mode, the control unit 25 controls the arrival of raster information line by line (highlighting certain lines in the received information) to the corresponding node 26. Nodes 2b convert the message to the format of television channels according to the algorithm described for the encoding system. The formatted data is transmitted through the corresponding codec 22 to the corresponding television signal receiver (not shown in the drawing).

The advantage of the system is the ability to perform all the functions of the MAC system using the same type of coding for all signals and the ability to transmit a large number of channels, including high-resolution channels.

Moreover, as you know, the system "MAC / packet S.I. Alyabyev, Broadcasting and electroacoustics, M., Radio and communications, 1999, 792

c.f ill. Page 704 / is characterized by the following features: compaction of analog and digital components separated by time, encoding of the image signal according to the MAC type, where the luminance signal and one of the two color difference signals are separately compressed and then placed within the line; batch seal for audio and data signals with their digital transmission; the possibility of using identification systems, limited access, scrambling the video signal and classifying audio signals.

At the same time, the compaction of analog and digital components with time division provides a large bandwidth at a given bandwidth of the radio channels.

Figure 4 presents an embodiment of the claimed system for transmitting information in a telecommunication network, including the Internet.

The system comprises a raster coding and / or decoding unit 26, a modulator 23, a demodulator 24, a control unit 25, a switching unit 21, a server 37, a client personal computer 49, and a monitor 50.

The claimed system operates as follows.

On the telecommunications network 32 through the switching node 31 to the server 37 receives service requests, the server 37 is connected to the network 32 through the switching node 31 or directly. Responses to requests can be received by the client over the network in a standard way. If it is necessary to transmit in an accelerated manner, the client can take advantage of the formed transmission channel, containing on the transmitting, receiving sides

nodes of raster coding and / or decoding, modulator and demodulator. To do this, the control signal supplied to the input 28 of the control unit 25 initiates the operation of the system. The unit 25 connects the server 37 through the switching unit 31 to the control bus 27 and the responses, upon the client’s request, are sent to the bitmap encoding and / or decoding unit 26, which is executed similarly to the encoding system and encoding and decoding system described above.

The digital data stream from the server enters the input unit 1 of the node 26, then is overwritten in RAM 3, then by the commands from the block 25, which is connected via the control bus to the elements 38-43 of the control unit 2 of the node 26, the process of encoding data into raster graphic formats is carried out data or in the color television standard and transmit them through the output unit 11 of the node 26 to the modulator 23, through which, from the control unit 25, the data is sent to the client demodulator 24. In this case, you can use any known standard communication channels that are consistent with the flow of information.

The demodulator receives a graphic file or image field of a CV TV response to a request, decodes it as decoded as described in the encoding and decoding system and encoding systems, visualizes it through the monitor 50 of computer 49.

It should be noted that the usual speed of information transfer in the telephone network does not exceed 33.6 Kbps, which, with large amounts of information consumed, greatly loads telephone lines and stations.

The inventive system can serve simultaneously a maximum of 135 Mbps: 33.6 Kbps "4000 people. at a speed of the telephone network or 400 people at a speed 10 times higher (336 Kbps) or 135: 1.5 to 90 people, respectively, when transmitting at the speed of normal MPEG video. With an average volume of requested data of 10 Mbit / s, the system is capable of serving 13 people per second at a speed of 1.5 Mbit / s or, respectively, 13x60x60 46800 people / hour.

Taking into account the average distribution of the time of requests and the amount of data, we can assume that the actual number of serviced requests will be 10 times larger, i.e. about 500,000 people.

At the same time, the speed of information flows from well-known Internet providers in the network of their international access is about 10-30 Mbit / s.

The number of such providers is about 10.

The figures show the importance of this application of the raster coding system in information transfer systems.

In addition, the essential features of the claimed systems is that when saving raster data files on magnetic, optical media or transferring them over digital networks, the encoding depth depends only on the graphic format used and can be a maximum of 32 bits / pixel or more, since practically these operations take place without loss of information.

When transmitting raster data, the coding depth depends only on the resolution of the receiving systems, due to

interference and other features, and transmission systems, and does not depend on the type of coding in the claimed system.

We can also say that this coding is also carried out with the aim of harmonizing the transmission system, visualization used, and ensuring the storage of information in the form of hard copies.

The advantage can also be considered the possibility of using such coding in batch or frame transmission of information that are widely used at present, as well as a uniform coding method, regardless of the source data.

It should be noted that encoding in the form of raster data is practically protected from the introduction of so-called “viruses, since graphic files are not executable computer systems, and encoded data is used only by specific output devices: audio, video, etc.
