Abstract

A method of interactive television providing for generating, transforming or displaying video information taking into account individual peculiarities of the user'"'"'s eye and individual peculiarities of a group of viewer'"'"'s eyes. The method provides simultaneously all or, at least, two operations from the above operations of formation, conversion and transmission of video signal and display of video information perceptible on the screen of information display facilities for one and/or a group of users or an unrestricted group of users. This is accomplished by one or a combination of various video editing and transmission adjustment techniques.

transmitting interrogation signals at least to two facilities for the given video signal formation facility, video signal conversion facilities and information displays facilities, in which the interrogation signal is taken into account with respective

forming of video signals,

converting of video signals and

forming of video image.

2. The method of claim 1, according to which the computing facility generates an interrogation signal for a group of users, which differs by the fact, that

summarizing interrogation signals for the users and/or groups of users taking part of the above group.

3. The method of claim 2, which differs by the fact, that summarizing interrogation signals coding external boundaries of video image sectors of the similar quality level for each level of video image quality coded in a series of interrogation signals for a group of users;

in this connection, for each interrogation signal the external boundary of the video image sector of each quality level comprises external boundaries of all video image sectors with indicated quality level.

4. The method of claim 2, which differs by the fact, that summarizing interrogation signals for the indicated users'"'"' group coding the quality level of video image for each sector of video image coded in a series of interrogation signals for a group of users;

in this connection, the quality level of each sector of interrogation signal video image for a group of users is taken as having the highest quality level for the corresponding sector of video image of each interrogation signal of users or a group of users forming a part of the given group.

5. The method of claim 1, or claim 2 or claim 3 or claim 4, which differs by the fact, that forming series of video signals of the entire video image of high and low quality level of video image in the facility of video signal formation, changing boundaries of each sector of video image in the video signal conversion facility except for the sector of video image of the highest quality level such that the internal boundaries of the above sector correspond to the external boundaries of the video signal area with a higher quality level of video image with respect to the sector with variable boundaries.

6. The method of claim 5, which differs by the fact, that converting a video signal of the entire video image into a series of video signals with quality level of the video image, with the lower quality level of the video image of the initial video signal.

7. The method of claim 5 or claim 6, which differs by the fact, that transmitting the video signal of the lowest quality level of video image via the data channels of data transmission facility to every facility of information display directly or via the facility of video signal conversion, associated with the relevant information display facility.
