Abstract

The invention discloses a streaming media self-adaption matching transmission method, system and server, and relates to the technical field of streaming media transmission. In a process of realizing IPTV video business, video streaming of different quality grades is sliced into code stream flow control blocks capable of performing decoding independently. In video business negotiation, an SDP (Session Description Protocol) adds information that describes the video streaming of different quality grades, and a user terminal analyzes the information and prompts user selection. The user terminal can perform feedback through an RTCP (RTP Control Protocol) according to network conditions and operating requirements, and negotiates with a server side to select flow control blocks of the video streaming of different quality grades, and thus the user terminal can realize smooth switching playing of the video steaming of different quality grades.

Description

technical field [0001] The invention relates to the technical field of streaming media transmission, in particular to a streaming media adaptive matching transmission method, system and server. Background technique [0002] There are roughly three ways of streaming media transmission: traditional streaming, progressive downloading, and adaptive streaming. RTSP (Real Time Streaming Protocol, real-time streaming protocol) is a protocol applied to traditional streaming, which establishes a session (Session) between the client and the server, and the server uses RTP (Real-time Transport Protocol, real-time transmission Protocol) The protocol encapsulates the video stream, and performs streaming output according to the video stream encoding bit rate. Progressive download is a simple transfer method for downloading files from an HTTP (Hypertext Transfer Protocol, Hypertext Transfer Protocol) WEB server. The client allows the media file to start playing while it is still being dow...
