DATA REDUNDANCY APPLICATION ALGORITHM FOR THE LOUDPLAY CLOUD GAMING PLATFORM Russian patent published in 2022 - IPC G06F17/14 H04N21/20 A63F13/355 

FIELD: computing technology.

SUBSTANCE: invention relates to the field of computing technology and network technologies. The technical result is achieved due to the forward error correction during the transmission of video stream data from the server to the client, performed by adding such additional service data to the transmitted information that allows errors to be corrected without an additional request, wherein when video stream data is being encoded, 2p verification characters are added on the server side to the block of m-characters; all m characters of the initial block are used in calculating each verification symbol, therefore, Fourier transforms are applied to accelerate the process of decoding the received data on the client; wherein a redundancy level changing algorithm depending on the duration of session, frame type, connection type, and the current state of the channel is applied; the streaming session is started with a video stream bitrate parameter equal to 10 Mbit/s; 100% redundancy is added during the first 30 seconds of the session, which is necessary to stabilise the data channel; and after 30 seconds, the redundancy level in the video stream is reduced to 20%, excluding the IDR-frame, the redundancy whereof is always maintained at 100%.

EFFECT: possibility of simultaneous increase in the smoothness of the image and up to a 30% reduction in the graphic image processing delay time.
