System.
Background technology
HTTP live streaming media is the biography of the stream data carrying out live streaming media using HTTP (HTML (Hypertext Markup Language))
Defeated.The agreement of existing market main flow includes the HLS of Apple（HTTP Live Streaming）, HDS (the HTTP of Adobe
Dynamic Streaming) and Microsoft HSS (HTTP Smooth Streaming).The core of above-mentioned three kinds of agreements
Scheming system is that live stream data is cut into slices, and generates the listed files information of continuous renewal to inform that playing end goes down
Carry, splice and play slice of data.It is advantageous that host-host protocol is simple, inferior position is that slice of data is subject to key frame interval shadow
Ring, interaction flow is complicated, client could be play after needing to accumulate several sections, and live playout-delay is larger.
The common live agreement of another kind of HTTP of industry is that live streaming data virtual is become an infinitely-great FLV
（FLASH VIDEO）File, and be transmitted by http protocol.This agreement keeps simplicity and the High Availabitity of http protocol
Property, and simplifying interaction protocol, playout-delay can significantly shorten.This agreement is commonly known as HDL, i.e. HTTP Download
Live streaming.

Under：
Request：
GET/live/livestream.flv?wsHost=flv.drag.test.com HTTP/1.1
accept:*/*
accept-encoding:gzip,deflate
accept-language:zh-CN
connection:Keep-Alive
host:www.abc.com
referer:http://www.abc.com/vplayer.swf
Response：
HTTP/1.1200OK
Content-Type:video/x-flv
FLV.......................................................................
