Abstract

The embodiment of the invention discloses a method for realizing hyper text transport protocol (HTTP)-based stream media service, which comprises the following steps that: a server sends live broadcast start time and the current time of the server so as to allow a client to determine position indicating information of media clips which need to be broadcasted according to the live broadcast start time and the current time of the server; the server receives the position indicating information of the media clips which need to be broadcasted from the client; and the server acquires the media clips corresponding to the position indicating information according to the position indicating information and sends a media clip document to the client. The embodiment of the invention also discloses a network system and network equipment. By the embodiment of the invention, the client can acquire the position information of media data on the server to realize HTTP-based stream media live broadcast service.

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.
