Abstract

The method and the system can be used in communicationsengineering for making interactive connection between Centre anduser for entertainment, educational or professional objectives andfor public opinion polls of the viewers' interests - peoplemetry.By the method additional information is superimposed on the normalvideosignal in digital form, two separate spots are formed in thevideopicture modulated as light and dark in cycle with thetransmitted data. When the additional information is converted thesingle-dimensional file of logical levels 0 & 1 is converted intotwo-dimensional, each cell of the single-dimensional file beingsubstituted by a column of two cells of different logical levels.The so modified videosignal is received by the user and by him theadditional digital information is separated and decoded. Thesystem consists of satellite, air and cable television (1a, 1b,1c) containing a generator of physical protocol, videosource,videomixer and transmitter, and of studio for videocassettes (2a)and multimedia studio (2b) including a generator for physicalprotocol, videosource, computer system for videocutting andrecording unit. These units are in connection with the user'sequipment containing a tuner (4), TV receiver (5) with opticalconverters (8, 9), video recorder (6), personal computer (7),transceiver module (3), remote control (10) and transmitter forfeedback to the server (12).6 claims, 5 figures
