Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0043] The system framework of the present invention is as figure 1 As shown, the core algorithm mainly includes two parts: the flow reduction algorithm and the scheduling performance evaluation. The process is as follows: Figure 4 As shown, the specific implementation steps are as follows:

[0044] Step 1, generate the media description file MPD: the streaming media server will encode the media content provided by the streaming media content provider with different bit rates, and the bit rates are {b 1 ,b 2 ,...,b L}, and b 1 2 L , where for any i and j if ii j , and then align and cut content copies of various bit rates into fixed-size (2-10 seconds) content slices, and then aggregate parameter information such as the bit rate, slice length, and data download URL of each content copy to form a media description file;

[0045] Step 2, establish ...

Abstract

The invention discloses a streaming connection scheduling method suitable for a multi-server adaptive streaming media system, which includes: a media description file is generated according to media content, a streaming connection is established between a streaming media client and a streaming media server, and the media description file is preloaded; each stream connection evaluates its data transmission performance according to the bit rate buffer media content slice corresponding to the network throughput, performs stream connection scheduling according to different stable conditions, evaluates the performance improvement of stream scheduling, and selects whether to perform stream recovery operation according to the evaluation result. The invention not only can evaluate the quality of the scheduling strategy, but also provides a reference for the system to cope with the change of the network condition, and the invention can simplify the connection without losing the robustness and the high fault-tolerant ability brought by the multi-servers to the streaming media system.

Description

technical field [0001] The invention belongs to the field of dynamic self-adaptive streaming media transmission based on the HTTP protocol, and in particular relates to a stream connection scheduling algorithm of a server self-adaptive streaming media system. Background technique [0002] With the development of the Internet, especially the development of emerging Internet services represented by online video and webcasting, the demand for bandwidth of streaming media services has gradually become the main demand for Internet bandwidth. Streaming media technology has gradually developed from a traditional connection-oriented protocol to a stateless adaptive streaming protocol based on HTTP. This streaming media solution based on the HTTP protocol has many advantages over traditional streaming media solutions, such as reusable existing HTTP infrastructure (including servers, proxies, and caches), reliable transmission, and easy passage through firewalls, etc. . [0003] In ...
