Description
Technical field
The present invention relates to media data storage, more particularly to RTSP Streaming Medias are converted into the technology of object storage.
Background technology
RTP (Real-time Transport Protocol write a Chinese character in simplified form RTP) is a network transmission association
View, is described in detail the normal data bag form for transmitting Voice ＆ Video on the internet.Real-time Transport Protocol is usually used in stream media system
(coordinating RTSP agreements).
Security Real Time Protocol (Secure Real-time Transport Protocol or SRTP) is passed in real time
A defined agreement on the basis of defeated agreement (RTP), it is intended to for the RTP in unicast and multicast application program
Data provide encryption, message authentication, completeness guarantee and protection of resetting.
Media business is a kind of new business for developing rapidly in recent years, and streaming media service utilizes streaming technology, in bag
Multimedia content data, such as data such as video, audio frequency are transmitted on exchange network.Streaming technology is mainly characterized by,
Continuous video and voice data are put into after treatment Website server, so, user can be downloaded while watching
With listen to, without just watching and listening to after whole file download to the user terminal for using.
Traditional stream media system is based on C/S (client/server) pattern, and all of client will take from Streaming Media
Business device obtains the streaming media resource required for it, therefore the performance requirement of streaming media is very high, and the number clients of its support
Amount is also very limited.
The stream media system being used widely in currently available technology is greatly reduced described based on P2P technologies
The calculating pressure and bandwidth occupancy of object storage.
Object is stored relative to NAS, SAN etc. traditional storage mode, in expansible row, security, high availability, economy
Property etc. convenient have greater advantage；The cloud storage almost all of main flow is set up on the basis of object storage.
RTSP (Real Time Streaming Protocol), RFC2326, real time streaming transport protocol is TCP/IP associations
An application layer protocol in view system, the IETF RFC submitted to by Columbia University, Netscape and RealNetworks companies
Standard.The protocol define how one-to-many application effectively transmits multi-medium data by IP network.RTSP is in system
It is located on RTP and RTCP in structure, it completes data transfer using TCP or UDP.HTTP compared with RTSP, HTTP request by
Client computer sends, and server responds；During using RTSP, client-server can send request, i.e. RTSP can be with
It is two-way.RTSP is the multimedia series flow agreement for controlling sound or image, and allows multiple crossfire demand modelings simultaneously,
Network communication used during transmission is reached an agreement on not in the range of its definition, and server end can voluntarily select to use TCP or UDP
To transmit streamed content, its grammer is similar with HTTP 1.1 with running, but is not specifically addressed by time synchronized, so comparing energy
Tolerant network postpones.And it is above-mentioned allow simultaneously multiple crossfire demand modelings (Multicast), except service can be reduced
The network consumption at device end, more further supports multi-party video conference (Video Conference).Because the running side with HTTP1.1
Formula is similar, so the cache function ＜ Cache ＞ of proxy server ＜ Proxy ＞ are applied equally to RTSP, and because RTSP has weight
New guide function, visual actual loading situation provides the server for servicing to change, to avoid excessive load centralization in same
Server and cause postpone.
The agreement is used for C/S models, is a text based agreement, for setting up and assisting at client and server end
The real-time streaming session of business.
Real-time streaming protocol (RTSP) is application level protocol, controls the transmission of real time data.RTSP is expansible there is provided one
Framework, the controlled program request for making real time data, such as audio ＆ video is possibly realized.Data source includes field data and is stored in editing
Middle data.The agreement purpose is the multiple data is activation connections of control, is to select sendaisle, such as UDP, multicast UDP and TCP,
Offer approach, and to select based on transmission mechanism provider's method on RTP.
The continuous Streaming Media of one or several time synchronizeds is set up and controlled to real-time streaming protocol (RTSP).Although continuous media
It is possible that stream is exchanged with controlling stream, and usual itself does not send continuous stream.In other words, RTSP serves as multimedia server
Network remote is controlled.RTSP connections are not tied to transport layer connection, such as TCP.During RTSP connects, RTSP user can open
Or multiple connections transmitted to server are closed to send RTSP requests.Additionally, Connectionless Transport Protocal, such as UDP can be used.
The stream of RTSP flow controls may use RTP, but RTSP operations are not relying on the transmission mechanism for carrying continuous media.
The operation that agreement is supported is as follows：
(1) media are retrieved from media server：User can submit a demonstration description to by HTTP or other methods.Such as
Demonstration is multicast, demonstrates formula just comprising the multicast address for continuous media and port.As demonstration is only sent to by unicast
User, user should provide destination address for safety.
(2) media server is invited and enters meeting：Media server can be invited to participate in the meeting for just carrying out, or playback matchmaker
Body, or record a portion, or all.This pattern is very useful in distributed educational applications, it is several in meeting can be in turn
By remote control button.
(3) media are added in ready-made lecture：As server tells that user can obtain additional media content, to live lecture
Seem and be particularly useful.As being similar in HTTP/1.1, RTSP requests can be by agency, passage and caching process.
RTSP agreement features：
(1) extensibility：New method and parameter are easily added into RTSP.
(2) easily parsing：RTSP can be parsed by standard HTTP or MIME resolvers.
(3) safety：RTSP uses safe web page mechanism.
(4) independently of transmission：RTSP can use unreliable datagram protocol (EDP), reliability datagram protocol (RDP)；Such as
Application layer reliability is realized, RSP can be used.
(5) multiserver is supported：Each stream can be placed on different server, and user side sets up several with different server automatically
Individual con current control connection, media sync is performed in transport layer.
(6) recording equipment control：The controllable record of agreement and playback apparatus.
(7) stream control is initially separated with meeting：The offer of conference initiation agreement is provided, or be can be used to create and only can be assessed a bid for tender
Knowledge number.In particular cases, invitation service device membership can be carried out with SIP or H.323.
(8) it is adapted to professional application：By SMPTE markers, RTSP supports frame level precision, it is allowed to remote digital editing.
(9) demonstration description is neutral：Agreement does not force special demonstration or meta file, can transmit Format Type used；However, drilling
Show that description must at least include a RTSP URL.
(10) agency is friendly with fire wall：Agreement can be processed by application and transport layer fire wall.Fire wall it is understood that
SETUP methods, are that UDP Media Streams open one " breach ".
(11) HTTP is friendly：Herein, RTSP advisably adopts HTTP ideas, makes present structure all reusable.Structure includes
Internet content selection platforms (PICS).Server state, RTSP are needed due in most of the cases controlling continuous media
Not only to HTFP adding methods.
(12) appropriate server controls：As user starts a stream, it is necessary to a stream can also be stopped.
(13) transmission is coordinated：Before actual treatment continuous media, user's tunable transmission method.
(14) performance is coordinated：Such as essential characteristic is invalid, it is necessary to have some cleaning mechanism to allow user to determine which kind of method is not given birth to
Effect.This allows user to propose suitable user interface.
The present invention provides a kind of mode that RTSP is converted to object storage.The system includes data source of stream media, processes
Server, streaming media clients, system is identified and deposited by the data addition that processing server sends data source of stream media
In storing up object storage, streaming media clients can direct play stream media data source media, the also playable matchmaker for having stored
Volume data, access the media data that stored preferentially can access other streaming media clients by way of P2P, otherwise just can be to
Object storage sends request.
The rear end storage of traditional Streaming Media is used mostly centralised storage, and Single Point of Faliure easily occurs, once first number of key
Go wrong according to server, performance and availability all can be greatly affected；In addition the performance and capacity of rear end storage also cannot be flexible
Extension.Traditional Streaming Media rear end storage server generally cannot quick response client the control command such as broadcasting, exist higher
