Abstract:
1. A method of interactive television wherein video signals are generated based on real time user perception of video images comprising the steps of: forming a video signal of an entire frame of an initial video image in a video signal formation component, said initial video image has a predetermined quality level and predetermined dimension; said initial video image is divided into a plurality of sector video images with predetermined boundaries, said sector video images having the same predetermined quality level; converting the video signal of said initial video image in a video signal transmitter conversion component into a series of sector video signals corresponding to said sector video images; transmitting said sector video signals from said transmitter conversion component via data channels, via a plurality of group user intermediate conversion components, to a plurality of user display components, said intermediate conversion components are substantially connected to said user display components; converting said quality levels of said sector video signals, such that a corresponding quality level of at least one said sector video image is successively reduced, said conversion is provided in said group user intermediate conversion components; forming an entire frame video image on the user display component, said user display component is connected to one group-user intermediate conversion component chosen from said plurality of group-user intermediate conversion components, said forming is based on said sector video signals, said entire frame video image being perceived by at least one user; said sector video images having the same predetermined boundaries and dynamically changeable quality levels; determining eye characteristics of a user by employing at least one sensor in operative communication with one eye of the user, said eye characteristics are determined relatively to the entire frame video image formed by the user display component and perceived at an eye of said user, and by employing data from said sensor to dynamically establish coding characteristics of each user; generating display interrogation signals within a plurality of computing components of a first type, each of said first type computing components is connected to a predetermined display component chosen from said user display components, taking into account an eye resolution of a corresponding user, and said coding characteristics; said display interrogation signals containing information on the quality levels of at least one sector of the video image; transmitting said display interrogation signals to one of a plurality of computing components of a second type, connected to said group-user intermediate conversion component; transmitting said display interrogation signals immediately to said user display component; generating a plurality of group interrogation signals within a plurality of computing components of the second type, said group interrogation signals are generated based on the display interrogation signals of at least one computing component connected to a corresponding computing component of the second type; calculating said quality levels of the sector video image within said second type computing components, in this connection, the quality level of said sector video signals is set as the highest quality level for the respective sectors of the video images corresponding to said display interrogation signals; converting the quality levels of said sector video signals, such that a corresponding quality level of at least one said sector video image is reduced, said conversion is provided in said group-user intermediate conversion component; wherein, said group interrogation signals are taken into account with a respective concurrent adjustment in converting said video signals; and said forming of the entire frame video image on said user display component, based on said sector video signals, is controlled by said display interrogation signal of said corresponding user.
