Problems solved by technology

However, when the network bandwidth continues to fluctuate for a short period of time, the above scheme will continuously adjust the video encoding bit rate up and down, resulting in short-term frequent fluctuations in video quality. This phenomenon of clear and blurred video images and frequent switching will seriously affect the user's business. perception
Therefore, such solutions cannot really improve the service quality of the streaming media service, and may even damage the user's subjective perception of the streaming media service QoE (Quality of Experience, quality of experience)

Abstract

The disclosure provides a stream media adaptive transmission method, terminal and system. The method includes: receiving streaming media data packets, predicting network conditions according to streaming media data packets, and obtaining network transmission prediction rate; monitoring streaming media service QoE according to streaming media data packets, and obtaining predicted QoE acceptable transmission rate according to service QoE; And obtain the player buffer margin and terminal CPU usage rate, obtain the recommended transmission rate according to the network transmission prediction rate, QoE acceptable transmission rate, player buffer margin and terminal CPU usage rate, and send the recommended transmission rate to the media server ; Wherein, the media server changes the coding rate of the encoder in real time based on the recommended transmission rate, so that the output rate of the streaming media data packet does not exceed the recommended transmission rate.

Description

technical field [0001] The present disclosure relates to the technical field of the Internet, and in particular to a streaming media adaptive transmission method, terminal and system. Background technique [0002] With the rapid development and popularization of FTTH (Fiber To The Home, fiber directly to the home), FTTB (Fiber to The Building, fiber to the building) optical fiber network and 4G+ (optimization technology of the fourth generation mobile communication technology) wireless network, live streaming HD (High Definition, high-definition) / UHD (Ultra High Definition, ultra-high-definition) video streaming services represented by on-demand and on-demand accounts for more than half of network traffic. HD / UHD video streaming has the characteristics of large traffic and continuous network, and is extremely sensitive to network fluctuations. Network packet loss delay, bandwidth jitter, etc. will cause varying degrees of damage to streaming media service quality. Therefore...
