FIELD: computer science, technology for dynamic control over volume of video data, sent to terminal from server, on basis of data transfer speed in the network.
SUBSTANCE: in the method for providing video data stream transfer service, server determines, whether filling is less than threshold value, or not less, than second threshold value of service, while filling represents amount of data, filling queue generation buffer in a terminal, while first threshold value is less than second threshold value. If the filling is less than first threshold value, than server provides data stream transfer service at predetermined bit transfer speed of service, which is less than current bit transfer speed of service. If the filling is equal to or greater than second threshold value, then server provides service of data stream transfer at predetermined service data transfer speed, which is greater than current bit transfer speed of service.
EFFECT: prevented sudden interruption or delay of data reproduction in the terminal.
