SOFTWARE AND HARDWARE COMPLEX FOR AUTOMATIC CALIBRATION OF MULTIPROJECTOR SYSTEMS WITH POSSIBILITY TO PLAY CONTENT IN HIGH-PERMISSION USING ENCRYPTION FACILITIES AND DIGITAL DISTRIBUTION, METHOD OF CONTENT ENCRYPTION FOR USE IN THE METHOD OF CONTENT REPRODUCING Russian patent published in 2018 - IPC G06F7/00 G06F21/60 H04N19/119 H04N9/31 H04N7/167 

Abstract RU 2657168 C2

FIELD: information technology.

SUBSTANCE: invention relates to the formation region and display images on curvilinear screens using projectors. Method for reproducing the licensed content includes the following phases: receive a frame of the original video image, divide it into parts, encrypt each part and send it to the auto-calibration module, creating for each projector a mask and filter, shader to compensate for geometric distortions on the screen surface, filter for compensation of stray glow from the projectors and a filter to compensate for differences in color, and automatically calibrating smooth transitions between projectors, impose appropriate filters on each projector and project on the screen from each projector the corresponding part of the video image frame, with the files, received as a result of division, and audio files are packed in one file, and during the download, the file is unpacked on the server side and the video and audio streams are decoded in parallel.

EFFECT: technical result is improved quality of displaying licensed encrypted content on a curved surface.
