Embodiment

[0040] Traditional data transmission is passive to packet loss, and the situation of packet loss cannot be controlled. This is the phenomenon of blurred screen and freeze that often occurs when we usually watch online videos. This embodiment considers how to effectively improve the user's viewing experience under the same network environment. This embodiment improves the processing of video data transmission from the following two aspects:

[0041] (1) Reduce the encoded GOP value:

[0042] Because the network packet loss rate is relatively high, we use a relatively small GOP value when encoding, and the time interval is about half a second. In this encoding method, the number of video I frames is relatively large. When the previous packet is lost, the client When the terminal is decoding, it can quickly find the next I frame within 1 second, so as to achieve the purpose of fast image reconstruction and reduce the frequency of blurred screens.

[0043] (2) according to the re...

Abstract

The invention relates to a control method and device, belonging to the field of stream media service quality control, and in particular relates to a network self-adaptive stream media service quality control method and device. An active packet loss treating process is adopted in the invention; when the packet loss condition is considered, a relatively small gop coding parameter is set; the network bandwidth is dynamically monitored; to realize the better play experience at a client side, the significances of an I frame, a P frame and a B frame and data information carried by various frames are comprehensively considered; according to the significances of various frames, a program performs packet loss processing according to the sequence of the B frame, the P frame and the I frame; due to the processing manner, the occurrence probability of a flower screen is reduced; and a relatively ideal watching effect can also be achieved basically when the bandwidth is not particularly small.

Description

technical field [0001] The invention relates to a control method and device, belonging to the field of streaming media service quality control, in particular to a network adaptive streaming media service quality control method and device. Background technique [0002] The number of frames is the amount of pictures transmitted in 1 second, and it can also be understood as how many times the graphics processor can refresh per second, usually expressed in fps (FramesPerSecond). Each frame is a still image, and displaying frames in rapid succession creates the illusion of motion. A high frame rate results in smoother, more realistic animations. The higher the frame rate (fps), the smoother the displayed motion will be. [0003] Due to the special physiological structure of the human eye, if the frame rate of the viewed picture is higher than 16, it will be considered coherent. This phenomenon is called visual persistence. That's why film footage is shot frame by frame and pla...
