Description

The method of transmission stream medium data and fluidisation transmitting device
Technical field
The present invention relates to data communication field, particularly relate to transmit the method for stream medium data and fluidisation transmission Device.
Background technology
The Internet as a kind of new media and information propagation pattern, be deep into global respectively Individual corner, same to radio and television, newspaper, magazine are the same, and the Internet the most progressively becomes the important sources of information One of.Rise and the development of the Internet are huge challenge for radio and television services, but also give simultaneously Radio and television services bring great opportunity to develop.Utilize the communications advantage and flexibly of the Internet Communication idea realizes radio and television and the Internet surging and combines, has complementary advantages thus capture Modern Communication The commanding elevation of technology and publicity initiative, be that Internet Age radio and television participate in network and win development The key of opportunity, is also the only ways developed in the Internet Age of radio and television.
At multimedia messages such as transmission over networks audio/videos, currently mainly there are download and two kinds of sides of stream transmission Case.One is to use the mode downloaded, and audio/video file is the biggest, so needing bigger storage Space and longer download time.Two is the time-base medias such as stream transmission audio/video animation, by Video service Device is to subscriber computer continuously, transmit in real time.In the system using stream transmission, user need not wait until Whole file is all downloaded complete, and has only to the start-up study through several seconds or tens seconds and can see See.When time-base media is play on a client, the remainder of file will continue in server on backstage Continuous download.Stream transmission is not only start-up study ten times, is shortened Radix Achyranthis Bidentatae, and need not the biggest delaying Deposit capacity.
Streaming Media refers to use in a network the continuous time-base media of streaming technology, i.e. Streaming Media to realize Key technology transmit as a stream exactly.Be transmitted by streaming technology, though the most crowded at network or Under the conditions of the dial-up connection that signal is very poor, it is also possible to provide sound shadow clear, unbroken to spectators, thus Arrowband the Internet transmission multimedia audio/video content is made to become possibility.
Existing streaming media server provides service for being embodied as more user, uses high-performance, height more CPU power consumption, expensive realizes streaming media, provides system collection by the ability providing CPU Cheng Du, wastes disposal ability and the resource of CPU greatly.Such as the most typical streaming media server Mainboard only can provide the streaming media service of 600-800Mbps, high-performance streaming media server master Plate 4000Mbps only, but price and costliness thereof, up to 100,000, power consumption is very big, even more than 200W.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of method transmitting stream medium data and fluidisation transmission Device, when solving streaming media server transmission stream medium data in conventional art, in order to be embodied as more use Family provides service, the problem that produced hardware resource waste is bigger, power consumption is higher.
A kind of method transmitting stream medium data in embodiments providing streaming media server, including:
Fluidisation transmitting device in streaming media server is according to the relative users configuration read from SRAM Information, obtains corresponding stream medium data from storage array；
In described streaming media server fluidisation transmitting device by described from storage array obtain corresponding Stream medium data is packed according to Ethernet protocol.
Embodiments provide a kind of fluidisation transmitting device, including:
Pretreatment module, for fluidizing the relative users configuration letter that transmitting device reads from SRAM Breath, then obtains corresponding stream medium data according to described user configuration information from storage array, and will The stream medium data obtained is sent to packetization module；
Packetization module: for fluidize stream medium data that pretreatment module sends over by transmitting device according to Ethernet protocol is packed, and is sent on Ethernet.
The embodiment of the present invention have employed increases an independent fluidisation transmission dress inside streaming media server Putting, utilize high-performance, high power consumption, the ability of expensive CPU that instead of in conventional art are embodied as More users provide service, utilize independent fluidisation transmitting device to process the stream medium data request of user, Reduce equipment cost, decrease power consumption.
