Abstract
The invention relates to a streaming media communication technology based on RTSP, in particular to a method for sending a RTSP request message in a Windows Media streaming media system. Aiming at the problem that: when a client of the streaming media podcasts, the users of a same GUID are out of limit, thus resulting in the failure of podcasting of the subsequent users; the invention discloses the method for sending the media request message in the streaming media system. The technical proposal of the invention comprises the following steps: (a) the user agent information of a streaming media client is generated; the GUID in the user agent information binds the identifying information of the streaming media client; (b) the streaming media client sends the RTSP request message carrying the user agent information to a server. The RTSP request message sending method of the invention is applied in the field of steaming media communication and has the advantages of avoiding the problem that broadcasting failure occurs owing to GUID collision when the Windows Media streaming media client podcasts and promoting the service quality of the streaming media terminal and success rate of access.
Description
Technical field
The present invention relates to streaming media communication technology, particularly the sending method of RTSP request message in the Windows Media stream media system based on RTSP.
Background technology
Windows Media is that the information streaming that Microsoft proposes is play scheme, is intended to Internet and Intranet and goes up the media stream transmission of Information that realizes comprising audio frequency, video information.Because Windows Media technology has characteristics such as convenience, advance, integration, low expense, gradually by the solution of numerous local side manufacturer, as the manufacturer of production set-top box as stream media system.The user terminal set-top box is sending RTSP (Real Time Streaming Protocol, when real time streaming transport protocol) asking, need carry User-Agent (user agent) information of client, comprise title, version number and the GUID (the unified identifier of the overall situation) of player, GUID is generated by the displacement numeral of network interface card reference numbers and cpu clock.As " wmplayer/9.0.0.3250 guid/3300AD50-2C39-46C0-AE0A-78F007CDDD99 " user agent's information for the STB terminal transmission, wherein " 3300AD50-2C39-46C0-AE0A " is the fix information of GUID, " 78F007CDDD99 " is the variable information of GUID, generated at random by cpu clock.When a plurality of terminal set top boxes send the RTSP request, different terminal set top boxes can occur and send identical GUID.
Stream media system request authentication process based on RTSP is generally: when IP set-top box incoming stream media server, user's request that Windows Media Server system docking is received has perfect authentication mechanism, guarantee networking user's use, forbid disabled user's access, the IP STB terminal sends the RTSP solicited message behind the authentication success, streaming media server judges whether the same GUID user who carries in the solicited message transfinites, and not transfiniting then provides service for the user again; If transfiniting then, refusal provides visit.Windows Media server has carried out limiting (the concurrent user number maximum number of giving tacit consent to same GUID is 10) for the concurrent user number of same GUID, when causing carrying out with the IP set-top box that the number of users of program request is concurrent to surpass 10, and subsequent user program request failure.
Summary of the invention
Technical problem to be solved by this invention is, carries out a sowing time at the Streaming Media client, and same GUID user is transfinited and caused the problem of subsequent user program request failure, and the method that sends the medium request message in a kind of stream media system is provided.
The technical scheme that the present invention solve the technical problem employing is that the method for transmission medium request message is characterized in that in the stream media system, comprises the following steps;
User agent's information of a, generation Streaming Media client, the identity identification information of the GUID binding Streaming Media client in described user agent's information;
B, Streaming Media user end to server send the RTSP solicited message of carrying user agent's information;
Further, among the described step a, the identity identification information of Streaming Media client is its MAC Address;
Further, the variable information of the GUID in described user agent's information is generated by its MAC Address.
The invention has the beneficial effects as follows, guaranteed that the GUID information that each stream media terminal sends has nothing in common with each other, avoided Windows Media Streaming Media client to carry out a sowing time because the problem that the GUID conflict can not be play has improved the service quality of stream media terminal and inserted success rate.
Embodiment
The invention will be further described below in conjunction with embodiment.
With the IP set-top box is that the Streaming Media client is an example, in order to guarantee that the GUID information that each IP set-top box sends has nothing in common with each other, the generation that generates GUID data in user agent's information (User-Agent) is made corresponding changes, the identity identification information of the GUID binding IP set-top box in the User-Agent information, such as the difference numbering of every IP set-top box, every IP set-top box MAC Address etc., the GUID that every IP set-top box is generated has uniqueness.The generation of GUID data is with reference to existing WMPlayer client signaling format, comprise fix information and variable information two parts data, wherein the generation of fix information is with existing identical, at the identity identification information of variable information part binding IP set-top box, as MAC Address.For further simplification, cancellation generates the variable information of GUID by the displacement numeral of cpu clock, and is directly generated the variable information of GUID by the MAC Address of IP set-top box.Guaranteed the data uniqueness of every IP set-top box transmission GUID information.Carry out seamless link in order to reach Windows Media Server, the IP set-top box WMPlayer client and server that generally need disguise oneself as carries out alternately.Generate User-Agent information by WMPlayer version number, GUID information, the IP set-top box sends the RTSP solicited message of carrying User-Agent information to server.For example, the MAC Address of IP set-top box is " 00 14 49 00 F3 3B ", the fix information of supposing the GUID of this IP set-top box is " 3300AD50-2C39-46C0-AE0A ", WMPlayer version number " 9.0.0.3250 ", then the User-Agent information of this IP set-top box is " wmplayer/9.0.0.3250guid/3300AD50-2C39-46C0-AE0A-0014-490 0-F33B ".Because the MAC Address uniqueness of IP set-top box is applied in the RTSP solicited message of Windows Media Streaming Media FTP client FTP, guaranteed the uniqueness of its GUID information, when thereby the same GUID user who avoids the Streaming Media client to carry out a sowing time is transfinited, the problem of subsequent user program request failure.
Claims (3)
1. send the method for medium request message in the stream media system, it is characterized in that, comprise the following steps;
User agent's information of a, generation Streaming Media client, the identity identification information of the GUID binding Streaming Media client in described user agent's information;
B, Streaming Media user end to server send the RTSP solicited message of carrying user agent's information.
2. send the method for medium request message in the stream media system as claimed in claim 1, it is characterized in that among the described step a, the identity identification information of Streaming Media client is its MAC Address.
