Embodiment
Fig. 1 is the block diagram according to the examples show of the network broadcasting device of the Upnp of utilization media server of the present invention.As shown in the figure, this device by for being connected of the Web broadcast catalogue that can not get the outside that Upnp supports, will category spanned file folder, to the CDS100 that manages with Web broadcast related content information; In fact be implemented as AVT110 in the media server on network to the Upnp AV of medium compensator transfer medium standards service; Above CDS100 is receiving integrated the browsing when application of relevant Internet Broadcast, passing on the Internet Broadcast content informations to Internet Broadcast client modules 130 and and after changing, changing and to the media information control part 120 of above CDS100 passback with XML file form with the form processing of regulation; Obtain broadcast content information from the Internet Broadcast LIST SERVER, in the Internet Broadcast client modules portion 130 of specific Internet Broadcast streaming media server place application Streaming Media; In the transportation protocol use of using broadcast service is under the situation of particular form, replace the medium compensator application be, to Web broadcast client modules portion 130 application medium and Streaming Media bridge services portion 140 from the medium that receive to the medium compensator that transmit; Using under the situation of the medium of the specific codec of support media compensator not, the compression/de-compression program that receives is changed to supported standard compression/gunzip, simultaneously code converter 150 compositions such as grade that transmit to Streaming Media bridge services device 140.
Below the usable condition of the present invention that as above constitutes is elaborated to Fig. 5 with reference to Fig. 2.
CDS (control directory services) 100 comes the media information of management of media server 200 as the mode of browsing with the standards service that comprises media server 200, in the present invention, Upnp is and unsupported external network broadcasting LIST SERVER 230 inserts, with the existing file class that under root folder, manages and project category and the similar file class of Web broadcast that appends, be created on as shown in Figure 3 under the root folder with the broadcast related content information of supervising the network.Under above Web broadcast file, produced with sub-folders such as a Web broadcast being categorized as purpose, Web TVs at all.
AVT (AV delivery service) 110 is as the Upnp AV standards service of using to medium compensator 210 transfer mediums on the media server on the network 200.It is URI and the illustration ID that obtains medium by this kind method.
In media information control part 120, CDS100 just serves as the effect to Web broadcast client modules portion 130 log on broadcast content information once more obtaining the Web broadcast file about when browsing application.Otherwise its effect is that XML transformation component 121 becomes XML file form to information conversion and returns to CDS100 by after the information that obtains from Web broadcast client modules portion 130 is changed and processes.By above media information control part 120 catalogue that is present on the particular network broadcasting LIST SERVER 230 is taken on the CDS100, standard judging part 122 and XML transformation component 121 are arranged in the inside of media information control part 120, whether standard judging part 122 is investigated and determined transportation protocol in broadcast content information is the form of supporting Upnp AV, if unsupported transportation protocol, will change the transfer path of relevant URI information to Streaming Media bridge services device, and agreement changes and record with basic RTSP also.Under the situation of using the Web broadcast streaming media server 240 of not supporting the Upnp agreement, last medium compensator 210 just can not apply for that carrying out direct medium to Web broadcast streaming media server 240 transmits, but adopts the mode of the indirect Streaming Media that utilizes Streaming Media bridge services portion 140.
Web broadcast client modules portion 130 is made up of the two large divisions.One is the catalogue client end 131 that obtains broadcast content information from Web broadcast LIST SERVER 230, and another one is the Streaming Media client end 132 to particular network broadcasting streaming media server application Streaming Media.130 effects that have nothing to do, use the client of existing particular network broadcasting with Upnp that take on of Web broadcast client modules portion.If Web broadcast streaming media server 240 is under the situation of using the Upnp AV standard agreement identical with RTSP, Streaming Media client end 132 is actually obsolete.Actual medium transmit and carry out between medium compensator 210 and Web broadcast streaming media server 240.In contrast, under the situation of not using standard agreement, just requiring to replace not transfer medium of Streaming Media client end 132, is under the situation of necessary medium at the medium that transmit, and transmits to medium compensator 210 by code conversion portion 150 and Streaming Media bridge services portion 140.
At the transportation protocol of broadcast service device is not support Upnp and be to use under the situation of ad hoc fashion, and Streaming Media bridge services portion 140 will replace medium compensator 210 to Web broadcast client modules portion 130 application medium.In fact medium transmit and carry out between Web broadcast client modules portion 130 and Web broadcast streaming media server 240, and transmit the medium that obtain at last to medium compensator 210 once more by Streaming Media bridge services portion 140.In order to realize this kind operation, the dialogue between 140 of Streaming Media bridge services devices and medium compensator 210 itself, the dialogue that Web broadcast client modules portion 130 and network streaming media server are 240 merges management.
Under medium compensator 210 situation for the medium that use unsupported specific compression/gunzip, code conversion portion 150 just carries out the compression/de-compression program to MPEG1, and 2, the operation of Upnp AV standard compression such as MP3/gunzip conversion.
In addition, transmitting network management CDS information processing process describes with reference to Fig. 4.
In addition, also only to make the file of distinguishing with type once more.If come for example from the Streaming Media of the network streaming media server 240 of network enabled broadcast, perhaps under the situation that application is browsed network broadcast file once more, CDS100 judge be not broadcast related this fact of information of information in the local data base but external network for information about after, will be to the actual conditions (S401) of media information control part 120 these applications of circular.The catalogue client end 131,132 (S402) of media information control part 120 this moment in will log on broadcast client module portion 130.
Catalogue client end 131 will be to related network Radio Broadcasting Agreements server 230 application broadcast content information (S403) because what use is the agreement that communicates with Web broadcast LIST SERVER 230 of wishing to use with the different user of Upnp.
Therefore, corresponding, will pass on to protocol client 131 from Web broadcast protocol server 230.At this moment, in fact it is to come together to transmit with the various search information such as radio station name of the URI that is similar to Web broadcast streaming media server 240, simultaneously when the information relevant with transportation protocol transmits together, Web broadcast client modules 130 itself also can be known this situation, these information relevant with Web broadcast stream matchmaker server 240 are passed to media information control part 120 once more, the XML transformation component 121 of media information control part 120 by inside it is transformed into CDS XML packet and extract with the information of the corresponding necessity of CDS (S404, S405).
At this moment, if judging the mode of relevant Streaming Media is not Upnp AV standard, just it is converted to and related network broadcasting streaming media server 240 corresponding streaming media servers 140, and related content is stored in the mapping table 141 interior (S406) of Streaming Media bridge services portion 140 inside.
Therefore, taked indirect Streaming Media mode by Streaming Media bridge services portion 140 at last, finished CDS and browsed as a result that XML transmits to CDS100, CDS100 passes on (S407) these contents to control point 220 again.
The CDS information of the related network broadcasting that obtains so just is stored in the locality DB and can extracts these data when being necessary.
The Web broadcast Streaming Media transmits processing procedure and is elaborated with reference to Fig. 5.
If in the specific medium compensator 210 of supporting Streaming Media, transmit particular network radio station project by control point 220 applications, medium compensator 210 just obtains relevant URI by the combination of AVT and the activity of AV setting URI, under the situation of using the normal stream media mode, if relevant URI becomes the specific URI in the real network broadcasting streaming media server 240, actual Streaming Media will merely be formed between medium compensator 210 and the Web broadcast streaming media server 240.If not so, relevant URI is under the situation that becomes Streaming Media bridge services portion 140, and Streaming Media bridge services device 140 will finish (S501) with the dialogue of the UpnpAV standard agreement of RTSP in medium compensator 210.
Streaming Media bridge services portion 140 is with reference to inner mapping table 141, in mapping table 141, find under the situation of URI of actual Web broadcast streaming media server 240, will pass on the Streaming Media client 132 of relevant URI in Web broadcast client modules portion 130, this moment Streaming Media client 132 will to the corresponding Web broadcast streaming media server 240 of relevant URI catalogue in apply for streaming media service (S502, S503).The management that Streaming Media bridge services portion 140 serves as these two kinds of dialogues, it comprise and RTSP similar Upnp AV standard agreement and other agreements between the signaling protocol mapping function.By answer or the signaling protocol mapping function of returning from Web broadcast streaming media server 240, finally transmit to medium compensator 210.
Under the situation that is not standard agreement, the medium transfer path is to be transmitted to Streaming Media client end 132 by above Web broadcast streaming media server 240, under the situation of using unsupported off-gauge compression/de-compression program, after in code converter 150, carrying out conversion with standard compression/gunzip of supporting the compression/de-compression program, the medium that change by Streaming Media bridge services portion 140 to medium compensator 210 transmit (S504, S505).
In medium compensator 210, if with 140 application dialogue changes of Streaming Media bridge services portion or application end-of-dialogue, will carry out relevant conversational operation, and change or end operation (S506) to carry out 240 corresponding dialogues of Streaming Media client 132 and Web broadcast streaming media server through the signaling protocol mapping table.
