METHOD FOR INTERACTIVE TELEVISION BROADCAST Russian patent published in 2016 - IPC H04N19/124 H04N21/43 

FIELD: telecommunications.

SUBSTANCE: invention relates to television video for transmission over a communication channel. Disclosed is a method of interactive television broadcasting, taking into account individual characteristics of vision, where method comprises experimental diagnosis of individual sensitivity of vision of user using user-visible images - visual stimuli with further convergence of results of said diagnostics in quantisation table. Control of foveation properties of sight of user, as well as compression and decompression and/or video transmission over a communication channel is made with due allowance for diagnostics of individual sensitivity of vision of user.

EFFECT: technical result is to provide interactive television broadcasting, which takes into account individual characteristics of user, which includes calculation of optimum table quantisation discrete wavelet transform coefficients (DWT) of all sizes, for all fields of view of user, adjusting quantisation coefficients depending on image area position on matrix after screen, therefore taking into account scale of distortion during compression, which is performed with use of DWT and using segments different quantisation tables for each type of segments.
