FIELD: television signal generation from image record signal and extraction of additional information from radiated signal. SUBSTANCE: method depends on elimination of non-required part of image information (thin structure) due to irreversible multiplexing followed by decompression of image record signal, that is, reduction of data and insertion of useful and control information in space cleared in this way. Device implementing this method functions to decode radiated analog signal processed according to this method. EFFECT: maximized amount of useful information transferred within framework of standard analog television broadcast. 27 cl, 5 dwg
