Embodiment Construction

[0038] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] It should be noted that, in the embodiment of the present invention, the video playing terminal may be various terminals capable of playing video, such as a smart TV, a mobile phone, a PC, etc., which is not limited herein.

[0040] The invention provides a dynamic code rate switching method.

[0041] refer to figure 1 , figure 1 It is a schematic flowchart of an embodiment of the dynamic code rate switching method of the present invention.

[0042] In one embodiment, the dynamic code rate switching method includes:

[0043] Step S10, the server acquires the download bit rate of the current video fragment of the program selected by the video playback terminal to download in the server;

[0044] In this embodiment, multiple fragment files of the same program with different code rates are stored on the server, ...

Abstract

The invention discloses a dynamic code rate switching method, comprising the steps of: a server obtaining a current video fragmentation downloading code rate when a video playing terminal selects a downloading program in the server; dynamically adjusting the code rate of a next video fragmentation to be downloaded by the video playing terminal in the sever according to the downloading code rate; and jointing the head leader of the next video fragmentation to be downloaded by the video playing terminal with the tail leader of a current video fragmentation in the server to form a joined video file, thereby allowing the video playing terminal to download the joined video file in a progressive download mode and play the joined video file. The invention also discloses a dynamic code rate switching server and system. According to the invention, dynamic code rate switching can be realized even the video playing terminal and the server do not support the same dynamic code rate switching technology, and the compatibility between the server and various video playing terminals is greatly improved.

Description

technical field [0001] The invention relates to the technical field of video playback, in particular to a dynamic code rate switching method, server and system. Background technique [0002] With the development of the Internet and multimedia technology, it has become a very popular entertainment method to obtain video content from the Internet through video playback terminals such as smart TVs, mobile phones, and PCs. However, since the process of obtaining video from the Internet is not through a private network but through a public network for data transmission, the network transmission rate cannot be guaranteed. When network performance deteriorates due to network jitter and large network delay fluctuations, users may need to continuously buffer while watching online videos through video playback terminals, resulting in continuous freezes in the video screen, which greatly affects the User viewing experience. [0003] At present, in order to solve the problem of networ...
