In this system 1 mentioned video data are requested from the Central station 2 controls the transfer of video data and transmitted over a telecommunications network 3 to the terminal communication device 4, where with the help of video display 41 of the communication terminal device 4, the video signals corresponding to image data are projected onto the retina 51 eye 5 of the user communication terminal device 4.

The video display 41, which can project the image signals directly on the retina 51 eye of the observer, i.e. the so-called virtual display images on the retina, described in Midwest video data via the video interface, for example in the form of RGB (red-green-blue) signal of NTSC (national standards Committee of the U.S. television), videographic signal VGA (video adapter) or other formatted color or monochrome video or graphic signal. The specialist should be clear that the described in the above-mentioned international applications WO 94/09472 and WO 97/37339 virtual displays display images on the retina and video interfaces can be the preferred way to coordinate so that you can effectively take other formats of television signals and especially digital video. By means not shown in the drawing of interface module television signals and video data can also be coordinated appropriately with the interface signals and corresponding to the received video data is converted so that they can be connected to the interface signals.

The video display 41 and other components of the communication terminal device 4 can be implemented in a common housing or in separate housings, and the video display 41, is placed in the first housing, for example, through a wired or the terminal device 4 can request and receive data from the Central station 2 control video transmission over a telecommunications network 3. Central station 2 controls the transfer of video data based on, for example, in normal communication server, which has a communication module 21 using the necessary hardware components and software for communication over a telecommunications network 3 with the communication terminal device 4. Telecommunication network 3 includes, for example, a fixed network, such as the public switched telephone network (PSTN), or a network based on Internet Protocol (IP), and/or a mobile radio network, such as network standard GSM or UMTS, which is connected with the Central station 2 control video transmission through not shown in the drawing the network nodes, such as the switching center mobile device (SMC) or service center short message (SCS). In variants of execution, in which the telecommunications network 3 includes a mobile radio network, at least some of the communication terminal device 4 is a mobile device radio communications such as mobile phones or portable or handheld computers with telecommunication functions using, for example, messages sloucenou radio (ODA) or in accordance with a suitable Protocol can communicate over used channel via the mobile radio network.

Selection commands and instructions that are entered by the user of the communication terminal device 4 through its elements 44 maintenance and transmitted to the Central station 2 control video transmission over a telecommunications network 3, are there communication module 21 and processed so that the video data requested by the user is read from the database 24, or from the file server Central station 2 controls the transmission of video data through the telecommunications network 3 is transmitted to the communication terminal device 4 of the user. The user may, for example, via a browser, such as Internet browser for direct access to the Internet, or browser WAP (wireless application Protocol), to view the headers of the video data and to request the desired video data, and for example, pause, rewind or fast-forward to run again or to interrupt the transmission of the desired data. The database 24, or the corresponding file server can be implemented in conjunction with other components of the Central station 2 controls the transfer of video data on a common or separate computer. Depending on the implementation of animazione target device 4 may contain the above (not shown in the drawing) of the interface module, who will coordinate the video data received from the Central station 2 controls the transfer of video data in accordance with the interface of video data; and matching the received video data is converted so that they can be enjoyed on the video interface. Coordination of video data corresponding to the video interface of the virtual display images on the retina, can also be made at the Central station 2 transmission control video.

As shown schematically in Fig.1, the video display device 41 contains a module 411 to determine the position of eyes of the user, which determines the current position of the observer's eye and transmits the data through the above interfaces or via optional wired or wireless interface module 42 send back messages about eye position of the user communication terminal device 4. Module to determine the position of eyes of the user, which determines the current position of the observer's eye based on the position of the pupil 52 eye of the observer, also described in the aforementioned international application WO/09472 and may be further modified by the specialist so that the obtained display 41. Depending on the implementation, you can provide data to the provisions of both eyes. Module 42 send back messages about eye position of the user communication terminal device 4, for example, a programmed software module running on the processor of the communication terminal device 4 transmits the received data of the current eye position of the observer by using the communication services of the communication terminal device 4 via the telecommunications network 2 to the Central station 2 controls the transfer of video data. In the Central station 2 controls the transfer of video data transferred to the data of the current provisions in the eyes of the user, received from the communication module 21, is transmitted to the module 22 filtering video data.

In the module 22 filtering video data, which may be implemented as programmable software module and/or using the corresponding processor of the signal processing to be transferred video data based on the received data of the current provisions of the eyes of the respective user are filtered so that the appropriate referred image data to the external area of the image which is projected comprehension, have a lower resolution than the video data corresponding to the internal areas of the image that is projected on the recess 511 of the retina 51. This particular property of the human eye, namely the fact that a small area of the retina that covers the angle of view is about 2, so-called fossa (cavity), corresponds to the highest visual acuity, can be used so that only the image areas that really projected into the recess 511, are transmitted with the most detailed high resolution, while the resolution, respectively, detail the content areas of the image that is projected out of the recess 511, are filtered, resulting in can very significantly reduce the amount of data to be transmitted, for the filtered video data compared to the unfiltered video data.

In one embodiment, the implementation module 22 filtering video data contains a function 221 crop that provides this filtering video data, on the basis of the actual position of the eyes some areas of the image corresponding to the video data filtered out. So, for example, at least some viltrumites, so the area of the image corresponding to the filtered video data is a segment extracted from the image area corresponding to the non-filtered image data, and this segment contains at least the above-mentioned inner region of the image. Therefore, must be transmitted only video data that correspond to the image areas, which are considered by the user in the details, which, especially in large full image areas substantially reduces the transferable amount of data for the filtered video data compared to the unfiltered video data.

When the filtered video data from the Central station 2 control video transmission over a telecommunications network 3 is transmitted to the communication target device and there with the virtual display 41 to display images on the retina is projected on the retina 51 eyes of the respective user, the user can enter a corrective influence, if the internal region of the high-resolution image, corresponding to the required high degree of detail of the content, not projected on Plumley sharpness. For this purpose, the communication terminal device 4 includes a correction module that can accept and remember the correction values entered by the user, for example, by means of the elements 44 of the service, such as control keys move the arrow keys "left", "right", "up" and "down", for example, these distances horizontally and vertically, and which corrects the data of the positions of the eyes of the user obtained through module 411 definitions of the provisions of the eyes of the user prior to transmission to the Central station 2 transmission control video so the area of the image with the highest resolution and, if necessary, with the highest detail content really is projected onto the recess 511. Thus obtained data of the provisions of the user's eyes and the position of the recess 511 on the retina of the user individually provided by the user into compliance, and individual correction values are stored, for example, on the map 45 with chip (chip-card) communication terminal device 4, for example, on the SIM card (card subscriber identity module), which can be removed from the communication terminal device 4. Module 43 adjusting the I on the processor of the communication terminal device 4, for example, on the processor chip card 45 communication terminal device 4.

The current data of the provisions of the eyes of the user received by the Central station 2 controls the transfer of video data and, if necessary, adjusted, can be stored, for example, using module 23 forecasting. Module 23 forecasting, for example, programmable software module that determines, based on sequence data of the current provisions in the eyes of the user, stored in the work process, expected next eye position, for example, using suitable regression functions. Thus, for example, to reduce the number of feedback messages on the provisions of the eyes of the user, transmitted from the communication terminal device 4 to the Central station 2 control video transmission, especially when a continuous change of position of the user's eyes. To directly transfer data to an abrupt change of the provisions of the user's eye to the Central station 2 control video transmission module 42 send back messages about eye position of the user in the communication terminal device 4 can detect, for example, abrupt razlichie, starting with a predefined threshold value data of this second specific position of the eyes directly transmit to the Central station 2 transmission control video.

In another embodiment, the module 23 forecasting in forecasting expected following provisions eye can besides take into account the content of the corresponding video data so that, for example, expected changes in eye position is correlated with the movement of large and/or the Central objects in the images corresponding to the image data. To perform this latter option may be preferred relevant data to analyze the process using suitable image processing so that their contents could be described in an abstract form, for example, using the notation of objects, vectors and/or coordinate values. Such abstract descriptions of the content may, for example, be stored together with the corresponding video data in the Bank 24 data and fed into the module 23 forecasting.

The user for receiving video information can be accrued payment, for example, directly by subtracting the amount of cash which, the credit card or by invoice for payment, for example, as part of the phone bill, and, for example, video data received per unit time related to a specific topic and/or combinations of such calculations can be recalculated according to the subscription.
