Technical field the Invention relates to the fields of electronics, communications, computer science, television, interactive television, industrial and medical theoutermost operations, designed to create the video screens that satisfy the query of the audience (users).

Interactive television provides the following operations: a) preparation and formation of the video signal, (b) conversion of the video signals, the video signal transmission, g) displaying a video image using the screen information display means, d) the formation of signals of a request for funds formation, transformation, and/or display information.

Foveation properties of the eye are used to reduce the redundancy of the video image by reducing spatial and color resolution of the video image or its parts, and use the dependence of the change of resolution from time presenting images to a user in accordance with a feature resolution of his eyes.

These abilities eyes widely studied in medicine, described as a function of the resolution of the eye, used to diagnose diseases of the eye and the whole body. The development of prior art sensors and properties determine the dynamic characteristics of the eye at the present time in the classroom MCI And 61 In 3/14 represented by a large number of devices and methods for Opredelenie USSR 145303 1960, U.S. patents 3507988, 1970, 04397531, 04720189, 04729652, 04946271, 04973149, 05430505, 05583795, 05649061), used only in aviation and military equipment.

For the dynamic characteristics of the eye include the coordinates and the direction of the optical axis of the eye, accommodation, convergence, pupil diameter and other characteristics. To the static characteristics of the eye include the long-term characteristics associated with the individual characteristics of the eye (myopia, astigmatism, color blindness and other ) and affect the function of the dependence of the spatial, temporal and color resolution of the eye from the azimuth angle and the elevation angle relative to the optical axes of the eyes.

In the analogues described proposals for the use according to the spatial resolution of azimuth and elevation plot of the video image relative to the optical axis of the eye in the means of formation, transformation, and transmission of video signals, and means of information display.

So in U.S. patent 04028725 "Video system high resolution (High - resolution vision system) the proposed device, which comprises means to generate video signals in the form of sensitive image sensors (video cameras) and information display means in the form of dirim lower spatial resolution video image, formed on the screen of the information display means for user line of sight to the periphery of the eye. That is implemented by use of means forming a video signal consisting of two television cameras with wide and narrow field of view. The video signals of high and low spatial resolution form in a television camera with dual concentric field of view. Transmit video signals through information channels on the display device, equipped with two cathode ray tubes using the optical system together form a video image consisting of two parts: a wide area with low resolution and narrow stretch - high. Servopress optical mechanism combines the two images and dynamically combines the center of the image to high resolution with an optical axis of the eye of the user. Servopress optical mechanism includes an optical sensor, which dynamically determines the direction of the optical axis of the eye of the user, and generates the control signals, encoding the direction of an optical axis of the eye. Information channel transmit these signals to television permission. Thus, the user's eyes always looking at the image of high resolution on the display screen. The device allows you to work in binocular mode. It is possible to work with computer inputs in the display or from sensors or videomagician tape. This solution allows to provide the image processing for a single user.

U.S. patent 04348186 Installed on the pilot's helmet display computer image generator, connecting with the area of interest of the eye" (Pilot helmet mounted CIG display with eye coupled area of interest) are interesting in that they measure the position of the eyes and head of a user using a means of forming a video image of high resolution, mounted on the head, projecting area of the video image of increased resolution on the canopy and reflect its movement. The proposed tool is only suitable for individual use because it works by defining a region of interest in one eye. In the simulator, the proposed American authors, it is suggested to form parts of the video in the form of a series of concentric rings with different ranking so that the portions of the Central rings had more detail than the Device image, the corresponding instant view" (Momentary visual image apparatus) is the development of a U.S. patent 04348186. The specified technical solution is characterized by the fact that the coordinates of the line of sight of the eye dynamically determine the size foveation high resolution eye shape and move this area sections of the video image with a high level of quality on the screen faster saccadic eye movements. Also available outputs of the low-resolution image to synchronize with the means of displaying images of high resolution in azimuth and elevation. In one of the proposed options position sensor eye will be offered to the helmet.

In the independent claim of this patent proposed to provide electronic parcel merge images of the two resolutions. Tool and system are distinguished by the fact that the boundaries of the image dynamically is not regulated, and they only moved from one sight to another point of sight at high speed. Lot dimensions are determined by means of projecting high resolution images to knead the projection foveation region in a high-resolution image, and means pangelinan a symptom of this invention is the presence of only two sites with different resolution, moreover, the boundaries do not change the form and in every part of the permanent resolution.

In U.S. patent 04634384 "optical mixing images, tracking the movement of the head and/or eyes" (Head and/or eye tracked optically blended display system) described the design of the display, generating an image with a resolution corresponding to the spatial position foveation the eyes of an observer.

This system, as U.S. patent 05808589 "Optical system for a display device that is installed on the user's head, uniting the parts of the video high and low resolution" (Optical system for a headmounted display combining high and low resolution images) has only two areas and the boundaries of these areas are constant, respectively, and its scope is very narrow flight simulators, having a dome-shaped screens.

In U.S. patent 05808589 and other similar devices, helmet set information display means, an image is generated for each eye separately. Image areas of low and high resolution combined device in a single image. In the specified device uses two displays: high and low resolution, sootvetstvenno, but the permanent boundary between them. The proposed boundary should correspond to the boundary of the projection foveation region of the retina at the screen.

U.S. patent 05980044 "display Design, taking into account the area of interest using smooth boundary errors combine images" (Area of interest display system with image combining using error dithering), developing U.S. patent 05326266 provides docdisplay system high and low resolution, and the means for their integration and especially methods of combining two images. Moreover, it is proposed to consider the current position of the user's eyes.

In U.S. patent 04513317 "Stabilized on the retina television screen with different resolution" (Retinally stabilized differential resolution television display) proposed to use foveation properties of the eye in the TV display, creating on the screen two zones: high and low resolution in a raster scan image. The device uses a special camera that generates two image areas of high and low resolution and their location depending on the coordinates of the eye. Moreover, the resolution of the high resolution is determined by the best beam electrolicious tube.

The disadvantage of this method is the impossibility of its use at large distances and/or for multiple users at the same time.

Also foveation properties of the eye used to reduce the bandwidth of the video system channel, as for example in U.S. patent 04405943 System narrowband closed lines of communication and control remote-controlled device" (Low bandwidth closed loop imagery control and communication system for remotly piloted whicle). The system is designed to reduce bandwidth "closed video lines and communication system for remote control aircraft.

The device consists of two parts: a remote part comprising a digital camera, the memory, the receiver and the reader video with different resolution; local part comprising means for generating signals of the query ( ) and means of transfer of this information to the unmanned aerial vehicle.

Characteristic for all these devices and methods is the individual nature of their application in aviation simulators, industrial or military applications. The vast majority of the considered technical solutions orientirovaniyu, what is the distance from the source of video information to the user is minimal. It is limited to the period of the information signal on the information channels from the user to the source video and back. It must be less than the period of the optical axis of the eye from one pixel to another pixel of the video frame as perceived by the user. Otherwise, on the edges of a video image during rotation of the optical axis of the eye of the user will experience video problems. For signal transmission request from the information display means to a source of video information must be arranged in operative communication line (On-line).

To prevent deterioration of visual perception of video due to the detection by the eye of the user edge effects in a number of patents, for example in U.S. patent 05071209 System of nonlinear projection with variable resolution" (Variable acuity non linear projection system) is proposed to abandon the clear edges of a video image, and to create an image with smoothly resizable pixels, each of which corresponds to function according to the resolution of the eye. If bysani over a large surface and will not be visible user or easily disposable.

For use foveation properties of the eye of the user group in the U.S. patent N4859050, 1989, describes a "Method and system for generating a synchronized visual presentation and performance for many of the audience" (Method and system for generation of a visual presentation and looking viewers). According to this method, the video pre-cleared and recorded on high-quality equipment for subsequent presentation on a television screen. In front of the screen a person sits and watches the view. The movement of the human eye is monitored by the sensor, which determines the coordinates of the intersection of the optical axis of the eye to the screen. The computer converts the sensor data, calculates which objects presented on the screen at any given time, the viewer looks and outputs on the graphics monitor image of these objects screen, looking at the viewer. Next, using the second graphical monitor, cameras and optical devices put signals of the original view and the graphics monitor. The output signal from a video camera recorded on a second tape of the second VCR with standard quality. From the second cassette is removed irrelevant in the opinion of the expert elements of the ako sufficiently displays the individual properties of an individual user. The proposed method inherent property that makes it impossible to use in an interactive television, a lack of dynamism.

In the patent of the Russian Federation 2134053 "the Way the video and device for its implementation", in which data about the coordinates and orientation of the user's eye shape signals, encoding the boundaries of the image and level of quality within each plot, serves these signals on the vehicle information display in the instrument of formation of information, transforming the source video signal and control the output video so that reduce environmental restrictions on the creation of the video.

Materials explaining the essence of the invention
1. Way interactive television using foveation properties of the eyes of individual and group users, protecting information from unauthorized access and distribution, detailed functional diagram of Fig.1. It presents a variant of the television interact the formation, and for at least one individual who perceives a video on one means of displaying information. It includes the following operations:
POS. 1 - in the means of forming a video signal to form a video signal of a video image (A1). The video image corresponding to the generated signals may consist of one parcel with a constant level of quality as traditional television (A1-1-1), such as conventionally shown in Fig.2 POS. 2, or of two or more sections with different levels of quality intended for broadcast on a multi-screen information display means (A1-1-2) POS.3, 4, 5.

The video can be formed with a constant time-quality video (A1-2-1) or to have a variable time-level video quality (A1-2-2).

The quality level of the video signal and its corresponding plot of the video image can be represented by the following characteristics or parameters:
- spatial resolution of the encoded video image (number of pixels in the video image);
- color-resolution pixel, namely the number of colors which are able to form a single who Yu, characterized by the frame rate within the site and time of submission sites video;
- contrast video images;
- used types of scalability, such as: signal-to-noise ratio; and other

Video form with constant time bounds (A3-1) or with variable time boundaries (A3-2). At the same time on different parts form the video signals with the same level of quality (see also Fig.3A POS. 6) (A1-1-2) or with different quality levels (A1-2-2) (see also Fig.2B or 3b). Conventionally, the plots in Fig.2 and 3 is represented by three quality levels: low (Ref. 7), medium (Ref. 8) and the highest quality video signal (POS.9).

The means of creating a video form video offline (A2-3-1), i.e. without control signals, or signals of the query (Fig.1 POS.1) coding for the quality sections of the video image, and/or generate signals with variable levels of quality within a specified area of the video image (A2-3-2) and/or at the request signals, encoding the boundaries of video image, generate video signals with variable boundaries within these areas (A2-2-2). Areas may cover a portion of the image, all ISO means forming signal can be used camcorder, in particular camcorder with the ability to generate complementary signals of different quality levels, for example, shown in Fig.2A, 2D, 2F, 2H (POS.2, 3, 4, 5), or camcorder that can with regard to the request signals, the coding parcel boundaries and/or the quality level of the video signal in given areas, to change the orientation and/or field of view when the depth of focus and/or aperture of the camera lens. You can also use combinations of two or more cameras with different level of quality, as in U.S. patent 4028725.

If the source video using the means of reproduction of video signals, this device has the ability to signal the request to read a portion of the recorded information reproducing only those pre-divided recording areas of the storage medium, which correspond to different parts of the video and/or different levels of video quality in the boundaries of the specified area of the video image with consideration of the request signals. The video signals can be generated in a computer input device that generates sign-text information or virtual reality, like computer games.

Inspire is the Russia 021498908 and in U.S. patent 4028725.

The purpose of this split video into sections and reduce the level of quality on all or specific parts of the video is to reduce the information amount of a video signal transmitted via information channels and to reduce the information redundancy of the video image generated by the screen information display means.

POS. 10 to transmit video signals through the information channels of source video data, which are the means of creating a video or a tool to convert the video signal into two or more consumers of video signals, which are a tool to convert video signals and at least one means of displaying information (B1), respectively, as it is carried out at broadcast over the network (B2).

POS. 11 - transmit video signals through information channels from a single source of video signals to a single consumer video signals (B2).

The video signals are transmitted to each designated facility in full or in accordance with the request signals, encoding the boundaries of video signals and/or the level of quality within areas of the video that is passed in the reduced volume information.

The transmission view is about the established communication channel receives individual signals or video signals video sites. When transmitting signals to one or groups of users via a transmitter similar to the transmitter of a cellular communication system, all users with broadcasting receivers corresponding range and are within range of the transmitter, constitute one group of users. The transmitter broadcasts the whole video, commissioned by a group of users, and in accordance with the individual signals of the request form information channels associated with a particular user, such as passing on his receiver coordinates of the video section of the video, or the keys to decrypt ordered by the user section of the video. For the case when the user does not generate a signal request, he can get the whole group video signal for subsequent conversion and/or display of video, commissioned by a group of users.

POS.12 - in conversion tool video with consideration of request signals convert video with permanent parcel boundaries and/or with a constant level of quality within these areas or pings, encoding the boundaries of video and/or quality levels of the video sites videosor is with variable levels of quality within these areas (B2).

Conversion tool video when converting the video signal to reduce the surface area of a video image of at least one signal received on the conversion tool (B1), and/or reduce the quality level of at least one video signal by reducing one or more parameters of the level of quality at the same time.

Convert video with consideration of request signals produced in one or more stages depending on the number of users with sensors, which determine the characteristics of the eye and from the branching patterns of the users location.

Conversion of video signals can be divided into stages.

The first stage of conversion, this conversion on total request signal at the city level and/or at the district level, and/or at the quarter level (also available in other grades and it doesn't really matter), i.e. at the top level of the hierarchy layout users.

In the following steps of converting video signals perform the conversion on total request signal (obtained by summing the signals of demand from individual users and groups of users) on street-level home and/or at the last stage of the transformation perform the conversion of video signals taking into account the individual signals of the query directly on the users themselves, depending on the availability of data from sensors to users.

Conversion of video signals can be performed in two or more media conversion in parallel, for example to users perceiving a video on the different means of information display (see Fig.2B and 2C), and/or sequentially, the video with the same quality level Fig.2A is converted into a video image of Fig.2G for multiple users, and then the video image is converted into image boundaries and levels of quality sites video for a single user (Fig.2B or 2C).

Conversion tool in converting video signals dynamically reduce the amount of information of the video signals of the video image. Dynamic reduction of the volume video conversion tool with regard to signals that encode the orientation of the user's eyes, is described in U.S. patent 4405943. However, this method is suitable only for individual users.

POS.13 - using screens of display devices form a video image corresponding to the received video signals. Parts of the video image corresponding to the received video signals, have boundaries and level of quality of the video image corresponding to the characteristics postrow request, the characteristics of the user's eyes can not be measured by the sensors.

POS. 14 - when entering in the vehicle information display request signals encoding the boundaries of video and/or level of quality on specified areas other than the edges of the video signals received by the means of displaying information, in that the means forming the image boundaries and levels of quality corresponding to the request signal (D2). This task can be solved by means of displaying information previously proposed by the authors, based on cathode ray tubes, liquid crystal displays and others, for example as described in the patent of Russia 2134053.

POS.15 - one or more users perceive the image formed on the screen of at least one information display means (E). The user may be one, there may be two or more in a single video image, as shown in Fig.4.

The quality level of video image or its part, the eye of the user may be presented with the following characteristics or parameters:
- spatial-resolution video (minimum angular rasme perceived by the eye as a separate pixels);
- color resolution, the number of colors that can distinguish between the eyes in a single spherical angle;
- number of shades of gray color;
- temporal resolution, characterized by the frame rate within the site perceived by the eye as flicker;
- brightness,
- contrast video images;
and other

POS. 16 sensor or sensors dynamically define the characteristics of the eye relative to the video image perceived by the user, and generate an information request signals, encoding characteristics of the eye or eyes of several users, as shown in Fig.4 POS.25.

As characteristics of the eye can be used dynamically measured by the sensor or sensors: orientation, the coordinates of the eye relative to the video and other features. Thus define the coordinates of one of the two eyes of the user or a certain number of the total number of eyes or all of a user's eye, gathered at the screens. Possible that each user located at the screen with a separate sensor. Or each eye has an individual, such as helmet-mounted sensor.

POS. 18 - predatorially device (O1), in this dynamically changing characteristics, such as the coordinates and the direction of the optical axis of the eye, the depth of the accommodation, passed dynamically (O1-1) and slowly changing characteristics such as the diameter of the pupil function according to the resolution of the eye relative to the optical axis of the eye, transmit to the computing device periodically or initially injected into the memory of the computing device (O1-2).

Function according to the resolution of the eye is defined as depending on the mode and kind of repeatable data and subjective characteristics of the user.

POS.19 - on signals, crypto dynamic characteristics of the user's eyes, taking into account the functions according to the resolution of the eye, at the computing device generates the request signals, coded information about the boundaries of at least one portion of the video (K1) and/or about the quality levels of video image on at least one piece of video (K2), within which(s) provide the needs of the user's eyes, or a user perceives the video.

When determining the boundaries and levels of quality sites video solve the problem minimi is s video to minimum level when within a specified area of the eye, the user perceives the image as realistic. Minimizing the level of quality sections of the video image and the reduced size video sites of high level is produced at the earliest possible stages of formation, transformation, transmission of video signals or display information.

In the above analogues form only one request signal, which is fed to the means of forming, convert video or on the vehicle information display (patent of Russia 2134053). We propose to develop at least two request signal. In Fig.1 POS.20 shows the formation of the individual request signals to a single display means information on POS.21 - group signals request for two or more information display means or summary of request signals obtained by summing the individual and/or group of signals of the query.

POS. 22 - transmit individual request signal to the renderer (O2-3) and/or the conversion tool (O2-2) associated with the specified renderer information (O2-1-1).

POS. 14 by means of displaying information with regard to signal request) the supply of information.

At the same time, the signals of the query information display means can be enjoyed on a tool to convert video signals associated with the specified renderer information (O2-2-1) POS.23. In accordance with the signals of the query conversion tool convert borders and/or levels of quality sites video POS.12.

POS. 24 total transmit a request signal of the means for forming video signals (O2-2). In accordance with the request signal in the means of creating a video form video sites video with parcel boundaries and levels of quality within these areas, relevant to the needs of the user's eye, perceiving the video (B1, B2).

In accordance with these signals the request to the video signal sequentially reduces information redundancy with regard to the needs of user groups, gathered around a single screen, or group of users, simultaneously watching the video on many screens. This group can cover the entrance, house, street, city, etc. in a sequence, the signal reduces the redundancy to a level consistent with the needs of the eyes of one individual user sites with different levels of quality on the screen of the information display means.

In the vehicle information display, not taking into account the signals of the query form of the funds received from the generation or conversion of video signals, a video signal, consisting of parcel boundaries and level of quality corresponding to the group request signal (POS.13).

In the patent equivalent of the U.S. 4028725 form the control signals, i.e. signals that are generated based on the properties of the control object: camera, computer. In our offer produce and transmit the request signals, which characterize the properties of the user's eye.

In the proposed method, a single display device or group of devices display information common information channel, for example a feeder at the entrance to the house, gets the total information signal with reduced redundancy of video data. Generally users look into one video, so there is a possibility that increasing the number of users behind a single means of displaying information, the amount of transmitted video will grow or nonlinear does not change, as described in U.S. patent 4859050.

In addition, for users that have the characteristics of the eye measured by the sensors and for costminimising redundancy, and on a display means of the information not provided by the sensors is fed group video signal based on the summed signal of the request.

Concurrent execution of the tasks listed above allows you to perform the task.

All of the above features is necessary and sufficient to ensure the solutions and achievement of the technical result.

8. If the quality levels of the video signals of low and high levels of quality are characterized by the fact that the element video (pixel) video signal of low level is and video the proposed method under item 5, or 6, or 7, characterized in that the means of forming the video signal or the conversion tool video element video (pixel) video signal with reduced level of quality is defined as the average of the items of video information (pixels) of the video signal of high level of quality belonging to the plot of the video image, limited by the boundaries of the specified pixel video with low quality (A4/B8).

Video of the first advanced level form or convert the summation of a base video signal and a video of the advanced level of quality, so you can receive the video signal of the first high quality level. The second video of the advanced level of quality form or convert the summation of the signal base level and the video signal of the first and second advanced level of quality.

11. The described methods and devices of the formation and transformation of signals that produce the specified transformation without signal request. The algorithm incorporated in the means of generation or conversion, an input video signal is divided into several signals, mutually complementary. Can be used a means of creating a video like the one presented to /the Technique of film and television, 1999, 1, S. 21, "Technology Studio cameras and TV systems in the era of digital television. Part 2. The technology of cameras for HDTV. L. J. Smith.Thorpe, Sony Corp./, and a tool to convert video signals, similar to those described in "Digital processing of television and computer images. edit Zubarev Y. B. and Dvorkovich C. P. - M. , 1997, in the scheme 8.6 encoder video implement the solution: the signal base level and the video signal of the advanced level. Diagram of the encoder shown in Fig.14. For the inverse transform of the signals provided by the conversion in the conversion tool, associated with a particular means of displaying information, the decoder, in which for each piece of the video summarize the basic video signal and each of the extended video signal corresponding to video signals of a given number of quality levels. Functional diagram of the method according to p. 10 shown in Fig.15. From the closest of the method according to p. 5 it differs by the following operations:
POS.40 - in the means of forming video signals produce or tool to convert video convert video to several video video base and at least one advanced level of quality (A6/ 10-1).

POS. 41 - in conversion tool video signals to obtain a number of video signals of different levels of quality summarize the basic video quality and advanced levels of quality (b).

12. Distributed separately the signals are convenient to handle, cutting tool convert video signals from the video signals of the advanced level of the sites with the specified request signal boundaries. If oinformation, the pixel values of the video signals put on the whole frame or only in the area of high level of quality, for example, in the following way K-1 chroma signal pixels high level so that the average value of the chromaticity of superpixel multiplied by K, and the chromaticity of the last K-th pixel will be equal to the difference between the sum and the product. A similar approach is possible when the signals basic and advanced levels differ by the ratio of signal/noise ratio, frame rate, color and other characteristics of the level of video quality. Alternatively, when rejecting the calculation of amounts of works and differences, for the hue of the pixel is low take the color of one of the pixels of the original level, selected in the sequence is the same for each group of pixels, or different, or randomly. When the summation signal of high level for the entire image or only on the area of high level To-1 pixel comes from a video of the advanced level, and one pixel of the signal baseline.

13. To simplify the calculations proposed for the formation of a pixel signal of a low level view of the level of quality.

For example, the process of converting video signals of a video image of a number of quality levels in basic and advanced levels of quality signals without signals request the proposed method under item 6, or 9, or 10, characterized in that the signal is low, relative to the source, level of quality is formed by aggregating information from several (K) nearby pixels of the original video signal, and dividing this sum by the number of pixels in one pixel of the video signal of low level. For example, the chromaticity of a few pixels is added up and divided by the summed number of pixels (To). After processing all pixels of the video signal of the original level, get a video of the entire frame is low and accordingly reduced dimensionality. On the other hand, the signals K-1 pixels from the initial level pass in the generated video signal of high level. This procedure may be repeated by the number of quality levels of the video signals minus 1. The total number of all signals is not greater than the volume of the video signals of the highest quality, with boundary equal to the borders of the video.

Video basic level comes on information channels on all Soi, the obtained(s) in the respective encoders. In the decoders (adders) are summed video on sites video and send SDI video signal, consisting of areas with variable boundaries and different levels of video quality on specified areas.

The method may be used in conjunction with existing video standards PAL, SECAM NTSC, if as a basic video using standard distributed over networks or essential, and advanced signals propagate along separate information channels.

14. For example, if the request signal is determined at the stage of formation or transformation, as defined by sections cover the entire frame of video, then transfer operation request signal can be adjusted and limited to all sites, i.e., only the most high quality video to their time to pass on SOYBEAN users that they look at the moment. And other areas or even less quality than the previous level, or other boundaries, or not sent, depending on the load transfer medium and condition, and criticality transmission time poceski, dynamically providing possible or necessary to the performance of the funds transfer, quality customer service, which entered the sign of a given signal request.

15. The method according to p. 5, or 6, or 10, wherein the pre-recorded video sites video source quality level (A9-1), the means of forming a video signal reproducing every part of the video quality, given request signals, for which the media with parallel write data in parallel to the address recorded video sites video with original quality, means forming video signals when playing a video with the original level of quality reproduce parallel reading several sections of the media, when playing a video with low read part simultaneously recorded sites video (A9-2).

The feasibility of the invention
To demonstrate the feasibility of the proposed method of interactive television using foveation properties of the eyes of individual and group users, and demonstrate the provision of technical financial p is s foveation properties of the eyes of individual and group users when solving the problem of television broadcasting in high definition.

When implementing claimed by the authors of the method consider the case where the formation of the video signal produced by using the same means of video - TV high definition cameras. In accordance with dependent way 7 convert video only video in the series of video signals of different levels of quality. Ask three quality levels: the first is the lowest level of video quality meets the standard SECAM (625625 pixels in the frame), the first higher level of quality corresponds to the spatial resolution (12501250 pixels in the frame), which is 2 times larger than the spatial resolution of standard SECAM, the second a higher level of quality corresponds to a resolution comparable high-definition television HDTV (25002500 pixels in the frame), which is 4 times larger than the spatial resolution of standard SECAM.

Assume that the existing and the claimed methods are implemented in the following television system, in which:
users simultaneously vepris.13 and POS.14);
- each information display means at the same time is an average of two users (the first level, 2 user);
every 10 information display means are located in one staircase at home and connected to one access means broadcast video signals (second level, 20 users);
every 10 entrances of homes connected to the housing means broadcast video signal (level 3, 200 users);
every 10 houses connected information channels with street by means of broadcast video signals (level 4, 2000 users);
every 10 streets connected information channels with the quarterly means of broadcast video signals (level 5, 20000 users);
every 10 blocks connected by channels with the district by means of broadcast video signals (level 6, 200000 users);
every 10 districts connected information channels with the city by means of broadcast video signals (7 level, 2000000 users).

Assume that users in both television means are located at a distance of 3 m from the screen, perpendicular to the optical axis of the eye, have a size of 57 cm diagonal and aspect ratio 3 to 4. With regard to options agenie, having on the outer border of the spatial resolution corresponding to the resolution of a television video signal of the lowest level of quality, will not exceed 128128 pixels, and the second a higher level of quality will not exceed 6464 pixels. For both techniques discussed in section with a diameter of 1 cm spatial resolution generated in the vehicle information display video broadcast signal is below the spatial resolution of the user's eyes. Thus both methods form a video image having subjectively the same level of quality.

Define the amount of information of the video signals transmitted via information channels from forming video signals to the display means of the information in the existing method for cable television: the number of rows - 2500; the number of pixels in the row (number of columns) - 2500; the amount of video information of one pixel is 2 bytes; the amount of video information of one frame is 12.5 MB; frame rate is 24 frames/sec; the amount of video information transmitted for each information channel HDTV - 300 MB/s; length TV the channels level entrance, house, street, neighbourhood, district and city information channels of the lower level are connected at an arbitrary point: the length of an access television channel 50; house - 200; street - 1000; quarterly - 3000; district - 5000; urban - 10000.

Total traffic video information transmission from the access television channels to display products 3000000 MBkm/s

Total traffic video information transmission (MBkm/s) for all vnutripodezdnaya television channels - 1500000; intra - 600000; nutrilion - 600000; intra - 150000; intra-district - 45000; intra - 30000.

Total traffic video information transmission through all information channels HDTV - 5508000 MBkm/s

Define the amount of information transmitted over communication channels in the television broadcasting system using the proposed methods.

Unlike the existing method of television broadcast offered us the method further provides for the presence of dynamic feedback control quality video sites for individual and group users. Oprhanage the method according to p. 1 sensors associated with means of displaying video information, determine the dynamic characteristics of the eye relative to the video image generated by the tool information display (POS. 16) (And). For example, the coordinates and orientation of the optical axes of the eyes relative to the video image generated by means of displaying information, the method and device described in the patent of the USSR from 1959 or later U.S. patents 1983 and later dynamically generate the signals, their encoding, as described in the patent of the Russian Federation 2134053. Dynamically transmit signals, encoding the coordinates of the eyes relative to the video image, the computing device (POS.18) (A).

At the computing device in accordance with method 3 for each eye with regard to function according to the resolution of the eye (L) produce signals that encode the boundaries of the video image of the first high quality level and a second higher level of quality (Ref.27) (K1-1). Boundaries can be for example defined by the coordinates of the nodes (Fig.2 POS. 45, 46, 47, 48) broken line (POS.49), envelope plot of the first higher level of video quality (Ref. 50). The coordinates of the points set in the coordinate system associated with the boundaries of the plot define the boundaries equals the resolution to the lowest possible level of quality and consequently, the eye of the border is not visible. The first point (POS. 45) specify two coordinates X1 and Y1 a total of 22 bits of information. The coordinates of the second point (POS.46) you can set the value changes of coordinatesThe second coordinate in the transition from point POS.45 to point POS.46 remains constant. Coordinate 3rd set point value changes of coordinatesX when moving from point POS.46 to the point 47, the coordinates of The thus remain constant. Taking into account the geometrical features of the rectangle, finished 4th point on the border between the area of low quality and the site of the first high quality level.

Given the maximum size of the first area of high quality level horizontalX and verticallyUp to 128=27pixels video low quality, to specify the coordinates of the second point and each subsequent you will need 7+1 bit of information. The coordinates of the polyline (POS. 49), covering the area of the video image of the first high quality level (POS.50) will be given in full, when the coordinate of the next point will coincide with the coordinate of the starting point (POS.46). C is a rectangle, the total request signal of the first high quality level one information display means on one eye will be 22+28=38 bits/frame/eye.

Setting the coordinates of the first point (POS.51) a broken line (POS.52) covering the area of the second elevated relative to the first point of the first polyline (8+8=14 bits/frame), and setting the maximum size of the site the second higher level of quality, horizontally and vertically, not exceeding 64 pixel of the video image of low level request signal, encoding the boundaries of the area of the video image of the second high level, will be in one eye 14+26=28 bits/frame/eye.

For information display means serving one user at a frame rate of 24 fps, the request signals, encoding the boundaries of the video image of the first and second elevated levels of quality for one eye of the user, will make for one eye 24(38+16)= 1296 bits/s

Then, in accordance with method 2 in the computing device generates the total request signal (POS.28) (K1-2) encoding the boundaries of the video image of the first premium urope surface video cover with boundaries of the first high-level video image of each eye perceives the image.

When the frame rate of 24 frames/s request signals, encoding the boundaries of the video image of the first and second elevated levels of quality one display means, make four eyes 41296/8=648 bytes/sec

In accordance with method 5 request signals generated for one eye or the eyes of the users (Fig.9 POS.27/29 or 28/30), and passed to the renderer information and higher computing device (POS.31).

Calculate the maximum size of the request signal generated for the city means to generate video signals, or convert the video signals in accordance with method 3. Define the number of lots of the video image is equal to the number of pixels of video lower quality level, the number of quality levels - 3; number of bits to specify the quality level of one pixel is 2 bits; the frame frequency is 24 Hz; volume request signal quality levels of sections of the video - 2343 KB/s

The calculated request signal for all users of the city will be maea from the number of a user's eye, calculate the volume of request signals transmitted over communication channels. A special feature of this method is that the information transfer request signals each level combined into a "star".

Length television channel (m) from the information display means to access the computing device 60; up - pan-200; to street - 1000; up to quarter - 5000; to the district - 10000; to the city - 15000.

Total traffic signals transmission request for all information channels (MBkm/s) from each information display means to vnutripodezdnaya computing devices - 15,23; to intra - 19,89; to vnutriplitnykh - 38,97; to intra - 76,34; to intra-district - to 59.82; up due to 35.15.

Total traffic transmission request signals in accordance with the proposed method is 245,4 MBkm/s

Determine the volume of video information transmitted over communication channels from forming video signals to the means of displaying information in accordance with the claimed method. In accordance with method 11 form video and/or convert the video signals in the video signal: bases is VNA quality in accordance with the method proposed by p. 12 corresponds to the amount of video SECAM and is 1/16 of the amount of TV HDTV signal.

Total traffic transmission video signal baseline quality - SECAM (MBkm/s) for all vnutripodezdnaya television channels - 187500; intra - 112500; nutrilion - 18750; intra - 5625; intra-district - 938; intra - 188.

Total traffic video information transmission through all information channels HDTV 344250 MBkm/s

Distribution of advanced video quality levels in accordance with the claimed method 11 corresponds to the above structure of the request signals, and the structure of distribution of video basic level of quality in accordance with the method according to p. 11 and corresponds to the structure of distribution of HDTV.

Determine the amount of video information, the first and second extended levels of quality that you want to pass on one means of displaying information of the claimed method, taking the form of sections of rectangular video, as the number of eyes, at the same time perceiving the image formed by one screen means Otago box frame of the video signal of the first high-level quality - 32768 bytes. The amount of video information of one frame of the window signal of the second high level of quality is 8192 bytes. The amount of video information of one frame of the window signal of the first advanced level of quality is 24576 bytes. The amount of video information of one frame of the window signal of the second advanced level of quality is 7680 bytes. The amount of video information of the first and second extended levels of video quality perceived by the two eyes of the user is 65 KB.

Determine the maximum amount of video signals of the first and second high levels of quality that are generated or converted to urban telecentre (POS. 36) (A6-1/ 10-1) based on the fact that the points of view of all users uniformly cover the whole video.

The volume of the video signals of the first and second quality levels, formed or converted in accordance with method 11 is 15/16300=281 MB/s

Video this volume provide to the district a means of converting video signals (POS.10) (B1). Conversion tool video signals in accordance with a total request signal from 100000 users transform the boundaries of video enhanced levels of quality and reduce the total amount of giving will be 1%.

The decline of video on each subsequent level suppose that is approximated by an exponential function. Total traffic transmission of video information video enhanced quality levels (MBkm/s) for all vnutripodezdnaya television channels is 1206999; intra - 1014317; nutrilion - 753960; intra - 490007; intra-district - 119883; intra - 20763.

Total traffic signals basic and advanced levels of quality and signals the request for the proposed method will be 3261902 Mbitkm/s

Total traffic video information transmission through all information channels HDTV, as was calculated above, will be 5508000 MBkm/s

This value is significantly lower traffic transmission of high-definition video signals in accordance with existing methods.

The above model shows the implementation of the declared technical result of independent and some dependent ways in reducing traffic transmission, reduce the maximum flow of video information, the compatibility of the new television standards is x from the source video. Also, because the information channels of the lower levels of transfer limited amounts of video data, the received video frames do not provide value for other users.

In this example, all figures are given for the case when packing video on how JPEG, MPEG-1,2,3,4, or other use. Application packaging signals together with the proposed method will lead to a reduction in the absolute values of the information flow, but will retain their correlation and advantages of the proposed method.
