Embodiment
Below, in conjunction with the accompanying drawings structure and the effect thereof that is suitable for embodiments of the invention described, but diagram in the accompanying drawing and relevant description just are suitable for structure of the present invention and active a certain embodiment, and above-mentioned technological thought of the present invention and core texture are not limited thereto.
Fig. 3 is to being suitable for the illustration figure that streaming media service of the present invention provides the work of method to describe.In following explanation, the Streaming Media client is meant the mobile communication terminal with flow medium function.DST PLAYER just carries with a kind of form of application program in terminal, then it is considered as the main body of work in the process that the present invention will be described.
As shown in the figure, at first the session information request message is transmitted the streaming media server lead the streaming media service that is used to provide content of multimedia by the Streaming Media client.Transmit streaming media server URL (rtsp for example: // 150.150.141.143).At this moment, Liu's media server is included in Streaming Media layout table (step SGT) SDP inside and is provided to the Streaming Media client.SGT is meant: the URL Table that the content that can provide in the Streaming Media mode is provided to the user once, Live streaming arrangement information and to explanation (Description) of each content etc. makes the user can receive the content information that is upgraded in real time.
The Streaming Media client utilizes display unit to show the information that is included in the Streaming Media layout table (step SGT) to the user, and employed special browser this moment (Viewer) is by the application program of lift-launch in terminal with DST PLAYER.SGT by special browser, or utilized option keys to show to the user in the process of streaming media playing before the session that is used to carry out streaming media service begins.Simultaneously, SGT is comprised in SDP inside, and the Streaming Media client can be obtained SGT information and be stored into this locality from SDP.When server upgrades SGT, Liu's media client will store SGT again.
The user can obtain the tabulation and the additional information of content and select needed content from SGT.At this moment, the new URL that selects can be redirected (Redirect) and be delivered in the server, and the Streaming Media client is retrieved SGT when receiving SDP at every turn.Therefore store new SGT in the time of can being updated at the version of each SGT, thereby make the user can receive updated information.
Below, in conjunction with the accompanying drawings 4 and 5 pairs in accompanying drawing in the process of receiving stream media service, need to ask the situation of the streaming media service of other content of multimedia to describe.
In step in play stream media data (step S51) when pressing option keys (step S52), SGT will show (step S53) by the special browser of DST PLAYER.At this moment, the Streaming Media client will provide time-out (Pause) request message (step S54) to streaming media server.Then, the Streaming Media that is provided to the content of multimedia of Streaming Media client from streaming media server transmits and will temporarily be stopped.
The user selects needed content (step S55) by SGT.
The Streaming Media client is sent to streaming media server (step S56) with the URL of user-selected content.
Then, streaming media server is sent to Streaming Media client (step S57) with SDP.
The Streaming Media client is analyzed the SDP that receives from the Streaming Media client, and itself and existing SDP are compared.At this moment, will determine whether need again audio frequency and video to be set (step S58).
Again audio frequency and/or Video Decoder are set if desired, then resetting decoder (step S59) transmits request broadcast (PLAY) content of multimedia afterwards to server message, and accepting streaming medium content packet (step S60) from streaming media server.
By aforesaid explanation, under the prerequisite that does not break away from the main idea that requires in the claims, with field ABC under the present invention anyone has the ability to carry out various distortion and implements, therefore the technical scope of the present invention content that is not limited to be elaborated in specification, its change will belong in the claim scope of being put down in writing.
As mentioned above, the present invention provides by Streaming Media layout table is included among the SDP, and the user is confirmed various content information once, thereby eliminates the inconvenience that needs end session when playing new streaming medium content.
