Abstract

The embodiment of the invention discloses a method for realizing streaming media service based on a hyper text transport protocol (HTTP). The method comprises: a client sends a request, which is used for a server to feed back a response carrying a media presenting description file to the client according to the request, to the server; the client establishes a time synchronization relationship between the client and the server; the client confirms a uniform resource locator (URL) of a media segment required to be played; the client sends the URL of the media segment required to be played to the server so as to request a media segment file; and the client receives and plays the media segment file corresponding to the URL fed back by the server. According to the embodiment of the invention, the streaming media live broadcast service based on the HTTP can be realized.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of communication, and in particular to a method, a network system, a server and a network device for a streaming media service based on the hypertext transfer protocol HTTP. Background technique [0002] Streaming media services have developed rapidly with the popularity of the Internet. The streaming media service may adopt Hyper Text Transfer Protocol (Hyper Text Transfer Protocol, HTTP). A large number of infrastructures, including web servers and content delivery networks (CDN), can support HTTP transmission, and streaming media using HTTP is becoming a development trend.
