Embodiment

[0025] In this example, the network bandwidth is tested in the form of detection packets.

[0026] First, the server stores at least two video sources with different bit rates and resolutions, and stores its related information, which includes the corresponding resolution and playback address information. When the user orders the desired video, the client automatically selects the corresponding The resolution of the service level, link to the corresponding playback address to play, and then the client passes the test message transmission between the server and the client within a certain period of time, and counts the data between the server and the client according to the response message network bandwidth, and take the average value as the final calculated bandwidth, compare the bandwidth calculated in the last certain period of time with the bandwidth calculated this time, the certain time here can be 20 seconds (that is, divide the entire video playback time into processin...

Abstract

The invention relates to a network technology, which solves the problems of image frame loss and / or smearing and / or jiggling and / or long cache time of a current website during video transmission due to different or unstable bandwidths, and provides a self-adaptive method for controlling network video quality. The technical scheme of the self-adaptive method can be summarized as follows: at least two video sources of different code rates and definitions are provided in a service; and the sources are selected and switched by a client according to the detected network bandwidth. The self-adaptive method for controlling the network video quality has the beneficial effects that the self-adaptive method for controlling the network video quality is convenient for users, and is suitable for transmitting network video sources.

Description

technical field [0001] The present invention relates to network technology, in particular to network transmission technology. Background technique [0002] With the development of network broadband technology, various video websites have sprung up like mushrooms after rain. However, the traditional website video transmission technology - transmitting the same video with uniform resolution cannot meet the needs of users. First of all, different network bandwidths and different terminals Users have different requirements for video resolution. Secondly, due to the fluctuation and instability of bandwidth, under the premise of fixed video image frame rate and resolution, users can play video when the network condition is good and the available bandwidth is high. The video is smooth and clear, but when the network conditions become poor and the available bandwidth becomes low, the proper image frame rate cannot be guaranteed, which will cause image frame loss, smearing, and jitte...
