Each matrix element is a single inverter “radiation brightness of the colors R, G, B - codes” and contains /Fig.2, 3, 4/ opaque housing 11 form a rectangular parallele the peda of insulating material, in the input box which is placed one opaque MicrosoftR 12, performing the role of a front door attached to the first /free/ the end of micromeasurement 13, in the absence of a control pulse from unit 10 /output 1/ input box body 11 is closed by an opaque microsetella 12, second end micromeasurement 13 is rigidly fixed in the housing 11 and is connected through a diode to the first output of the generator 10. The control pulse has a duration of 0.1 MS, frequency of 25 Hz with an amplitude sufficient to trigger micromeasurement 13 bending /deformation of the bending/ [2, C. 26], and opens the passage to the emission color from the subject to the lens 15, which is fixed in the partition 14. For the microlens 15 role of the lens in its optical axis and at an angle of 45° to it consistently at an adequate distance from each other and are rigidly fixed on the number of digits in the code eight translucent microthermal 161-8. Each located ahead of microthermal 16 passes in the next flux is weakened by two times, which corresponds to the principle of binary code, which every microthermal 16 has a beam-splitting coating that performs the ratio of reflected radiation to a missed like 1:0,5 [3, c.223]. On the side of the housing 11 of the Converter, which turned micromirrors 16, o f the s eight identical microblocks 17 1-8photodetectors /Fig.5/, each of which contains three corresponding 211-3made in miniature form, the first photodetector 211at the receiving side has a red R microsocial, the second 212is at the receiving side green G microsocial, the third 213has a blue B microspatial. Of the reflected from the micromirrors 16 radiation flux sensor 211outputs the electric pulse R, the second photodetector 212outputs the irradiation of an electrical impulse corresponding to the color G, the third photodetector 213outputs the irradiation electrical pulse that corresponds to the color B. the Transducers are maintained respectively of three colors three functional parts [4, c.5], located respectively in blocks of keys 4, 5, 6, each functional part, in turn, blocks of keys consists of functional groups, each of which serves one's own inverter brightness emission colors of R, G, B - codes, functional groups in the block of keys on the number of items /converters/ in the matrix of the receiver 3 images. Functional groups performed identically /Fig.2, 3, 4/, each contains the number of digits in the code eight pulse amplifiers 181-8the input of each of which is connected to one output of the three in the passages R, G, B microbiome 17 photodetectors /Fig.5/, contains nine keys 191-9and one encoder 20, the first to fourth outputs of which are the outputs of the functional group, and together the outputs of all functional groups represent the outputs of the functional parts, i.e. the outputs of blocks 4, 5, 6 keys, each of which is in first 4×106output.

In the absence of a control pulse from the first output unit 10 micromeasurement 13 in an unstressed condition, an opaque MicrosoftR 12 closes the input window of the housing 11. With the arrival of the control pulse Utofrom the first output unit 10 /Fig.1/ microsocial 12 bending of micromeasurement 13 opens at 0.1 MS input window and the radiation flux from the lens 2 /Fig.1/ entered the microlens 15, which generates a stream of radiation arriving at the translucent micromirrors 16. The reflected radiation received at microsatellite R, G, B photodetectors in microplate 17 /Fig.5/.

With the pulse outputs of amplifiers 18 pulses with a duration of 0.01 MS. Block 188the pulse is fed in parallel to the first inputs Ufromkeys 198and 199and opens them, from the output of block 187impulse closes UCkey 198and opens the key 197hereinafter, this process of closing the previous key 197and the subsequent opening of the key 196repeats at a speed of propagation of light through the translucent microseries 16. With the weakening of the subsequent irradiation of the semi-transparent mirror 16 to the failure of the photodetectors 21 to the inputs of the pulse amplifier 18 to the photodetector unit 17, the signals will not be received, and accordingly there are no pulses on the inputs of the subsequent keys 19. For example take that last worked photodetector unit 174in the latter work the amplifier 184that the output signal UCclosed key 194and opened the key 194. At this point, the keys 198-195all closed, and the keys 193-1still not open. The key 199opened by a pulse from the amplifier 188and is in the open state until it impulse 25 Hz unit 10. As a result, the arrival time from the output of the key 199signal Uvydthe keys 199-5closed, and the keys 193-1is not already open, in the open state the AI is only one key 19 4therefore , the signal Uvydwith key 199there is just one public key 194and he is also one arrives at its fourth input of the encoder 20, which encrypts the impulse came to the fourth input of the unit 20, the binary is 0100, and from the output of the encoder should binary code 0100 registers unit.

Information about transition between scenes together with information about the type of transition between scenes is transferred to video decoder in the message of additional extension information, if the transition between the scenes represents a gradual transition between the scenes, algorithm of spatial-temporal masking of errors is used for masking the image, if the transition between the scenes represents a scene cut, and only a part of the image is lost or damaged, then spatial error masking is used to mask the lost or damaged part of the image, and if the whole image belonging to scene cut is lost or damaged, and the image begins a new scene, it is not masked.

EFFECT: creation of method, by means of which the appropriate form of error masking may be selected for frames which are subject to transitions between scenes in a video series.

SUBSTANCE: invention relates to communication, in particular, to reducing the message redundancy. The developed method allows transmitting additional data without increasing the volume of transmitted data with the transmission rate left intact. First, the initial image is separated into not overlapping range units to be classified. Here, note that every range unit is refereed to one of the three classes, and the said classification is applied to the domains and units from the code book as well. Additional data is entered into lower category of the domain or units indices, to the rest categories of indices of the domain of the initial image or units from the code book applied is the trial inversion procedure. Now, the domain indices and units from the code book are optimised to be transmitted, along with the data on indices of their orientation, over the communication channel. The receiving party isolates the additional data and restores the initial image.

EFFECT: transmission of additional data without increasing the common volume of transmitted data at the required transmission rate.

SUBSTANCE: invention refers to method and electronic device for determination of applicability of the encoded file in an application, which allows for using such type of files but has some restrictions related to properties of such file type, as well as to the computer-readable medium containing the computer programme for performing the said method. To fulfill the above method, the electronic device contains at least one block for correlating the files associated with the application, which accepts (50) at least one property of the encoded file and correlates (52) the property with the application, creates (54) an indicator showing whether the file can be used by the application relying on correlation, and connects (56) the indicator with the encrypted file for further provision of quick decision making regarding usage of the file by the application.

EFFECT: provision of quick choosing encoded files for usage by the application without preliminary decoding of the file.

SUBSTANCE: method contains steps of processing information on the basis of mathematical transformations, divisions of the image into blocks of the image and coding of the current block, and the division of the image is carried out repeatedly on square blocks whose sizes are defined by a mass of initial data. For blocks which are not analysed before, an un-oriented graph is built, whose each top corresponds to one of such blocks, and each block consistently subject to affine transformations. Each transformed block is compared to all other blocks and if the degree of distortions of such a block at replacement of one of other blocks satisfies with it to the set restrictions on quality of the image between corresponding tops the column create an edge for reception the column, minimal covering which the set of tops answers an optimum base subset of blocks. The information is compared with that stored in memory of the block therefore leaving the information on the storage of the image corresponding to the minimal volume of data necessary for restoration of the image, then the procedure is repeated for the next size of the square block.

EFFECT: increase in the factor of compression of the image with minimal loss of quality at its restoration.

SUBSTANCE: invention is related to method of reduction of redundancy of transmitted information. Invention actually consists in creation of method for additional information transmission at fractal coding of images. Transmission of additional information is carried out in the following manner: whenever initial image is compressed with the help of fractal compression method, in indices of domain units orientation binary sequence of three digits is recorded, which represents additional information, then based on this additional information processed domain is turned and brightness coefficients - o and contrast coefficients - s are searched for by method of least squares, which correspond to optimal values, at which the following expression is minimised: where {dij} and {rij} accordingly are values of pixels in domain and range areas, as a result of which optimal domain is found with account of inbuilt additional information for coding of range unit, after that indices of domains, coefficients of brightness and contrast, additional information are sent through communication channel. On receiving side additional information is separated and initial image is restored.

EFFECT: creation of method for additional information transmission with fractal coding of images.
