METHOD FOR INTERACTIVE TELEVISION USING FOVEAL PROPERTIES OF THE EYES OF INDIVIDUAL AND GROUPED USERS AND FOR PROTECTING VIDEO INFORMATION AGAINST THE UNAUTHORISED ACCESS, DISSEMINATION AND USE THEREOF
The invention relates to radio-electronic, telecommunication, television, interacting television, video telephone and videoconference communication engineering. Said method makes it possible to increase the ratio between the volume of useful video information and the total volume of video information transmitted to individual and grouped users, and reduce the volume of superfluous video information during the formation, conversion, transmission and display thereof, etc. The inventive method consists in forming request signals for at least one eye of one user or a group of users according to signals received from a transducer. Said signals define the characteristics of the eye and consider the function of the resolution power thereof. The request signals being transmitted to at least two forming, converting, transmitting and displaying means in which the video signals are formed, converted and transmitted, the video images are displayed on the terminals of the users with respect to said request signals.
