METHOD AND SYSTEM FOR ESTIMATING NETWORK THROUGHPUT WHEN TRANSMITTING VIDEO SIGNAL Russian patent published in 2020 - IPC H04N21/2662 

FIELD: physics.

SUBSTANCE: invention relates to the computer equipment. Method of estimating network throughput capacity during video signal transmission, in which determining the starting maximum bitrate, minimum useful bitrate, frame per second rate (FPS) for transmitting a video signal to a user device and a forward error correction (FEC) algorithm; determining the average number of packets per frame and the frame interval of the video signal based on the start bitrate and the FPS; transmitting a video signal to a user device with certain parameters in a predetermined time interval; determining, for each transmitted frame, packet loss when delivered to a user device; determining the number of fully assembled video signal frames on the user device, wherein, if the number of collected frames is greater than or equal to the minimum set number of collected frames determined based on the start bitrate and FPS, then determining the network throughput capacity as sufficient for video signal transmission with the specified parameters.

EFFECT: technical result consists in improvement of accuracy of determining network throughput when transmitting a video stream.
