Fig. 5 illustrates the flow chart of an embodiment of Rich Media of the present invention live broadcast service method.
As shown in Figure 5, in step 502, live person starts live client, and live client can to live management server application media distribution service; Respond the request of live client, live management server is live client allocation medium distribution services ability and Rich Media direct broadcast band address.Live client can be sent message request to intending the spectators that invite with modes such as note, Email or instant messages, carries said Rich Media direct broadcast band address in the message request.
In step 504, live client is obtained Rich Media's resource in real time, and uploads to media delivery service after converting the rich media data stream of prescribed form into.
In step 506, spectators import Rich Media direct broadcast band address or click the Rich Media direct broadcast band address that live person issues on networks in browser address bar, initiate to watch live request.Request gets into the live page after initiating, and Rich Media's player starts, and sets up between the media delivery service and watch live data channel.In response to the live request of watching that comprises Rich Media direct broadcast band address, media delivery service will send to Rich Media's player with Rich Media's corresponding rich media data stream in direct broadcast band address.
Live person stop live after, all are play live Rich Media's player and stop live automatically.
Live client can adopt multiple mode to obtain Rich Media's resource.For example, live client is from the real-time video/audio of terminal equipment production, and the professional etiquette of going forward side by side fixes and obtains video/audio data flow behind the coding of formula; Perhaps, live client is obtained the file of video, audio frequency, picture, common document types such as (DOC/PPT/PDF) from the terminal equipment local file system, and converts rich media data stream into; Perhaps, live client is obtained certain Rich Media's resource (comprising video, audio frequency, picture, webpage, common document) from network, and converts rich media data stream into.Those skilled in the art will appreciate that live client can adopt above-mentioned one or more modes to obtain Rich Media's resource, also can adopt other mode to obtain Rich Media's resource.Live client will be carried out the overlap-add procedure of video and audio frequency from the rich media data stream that the video/audio data flow of terminal equipment production and local file system or network obtain, and acquisition finally is used for live rich media data and flows.
Fig. 6 illustrates the flow chart of issue live content among the embodiment of Rich Media of the present invention live broadcast service method.
As shown in Figure 6, in step 602, live person starts live client, and live client is to the required media distribution service ability of live management server application live broadcast service.
In step 604, live management server carries out authentication to live client.For example, live management server requires live person to import username and password, perhaps directly communicates with live client, obtains the certificate of certification of live client etc.
In step 606, live management server judges according to the information that obtains whether authentication is passed through, if authentication is not passed through, then refuses the request of live client, if the step below continuing is passed through in authentication.
In step 608, live client is submitted this live maximum attendance, this live information such as time that possibly continue that needs support to live management server.
In step 610; Live management server verifies that whether live client has the ability to pay that this live broadcast service is provided or do not have the user right that this live broadcast service is provided, if do not have, then refuses the request of live client; Otherwise, the step below continuing.
In step 612, live management server is live client allocation medium distribution services ability and Rich Media direct broadcast band address.For example; The Rich Media direct broadcast band address that can distribute a URL form for each live person; To each live person; This direct broadcast band address is fixed and is unique, and live person can be published to the direct broadcast band address of oneself on the Internet, and the onlooker can watch up-to-date live content through this live address at any time.
In step 614, live client is sent and is watched live invitation, comprises Rich Media direct broadcast band address in the invitation.
In step 616, live client is obtained Rich Media's resource in real time, converts into to upload to media delivery service after rich media data flows.
Live client can send to media delivery service with rich media data flow point section, and every transmission success one piece of data stream is then deleted this segment data stream; Media delivery service saves as the rich media file of prescribed form with the rich media data received stream, stores in the file system on the position with Rich Media's direct broadcast band address, supplies viewer request to watch.
Fig. 7 illustrates that spectators watch the flow chart of live content among the embodiment of Rich Media of the present invention live broadcast service method.
In step 702, spectators initiate to watch live request according to Rich Media direct broadcast band address, start Rich Media's player.
In step 704, Rich Media's player is to the media server address at live management server queries live content place.
In step 706, whether live management server checking spectators have is watched live authority.For example live management server requires spectators to import username and password.Do not watch live authority if spectators do not have, then refuse spectators' request, watch live authority, the step below then continuing if spectators have.
In step 708, live management server returns the address of the media distribution service device at live content place to Rich Media's player.
In step 710～712, set up data channel between Rich Media's player and the media distribution service device, the media distribution service device sends to Rich Media's player with rich media data stream through data channel.
In step 714, Rich Media's player presents the content in this rich media data stream with forms such as image, sound, literal to spectators.
Among the embodiment on the present invention, live client and spectators are carried out authentication, live broadcast service is had control ability, be convenient to operation and promote through live management server.
Rich Media provided by the invention live broadcast service system and method; The live person of Rich Media (for example obtains Rich Media's resource through live client; Obtain real-time video-voice frequency flow or read local file or read the media file on the Internet through camera), to the live required conduit resource of live management server application; Live management server is verified live person's legal identity, is its allotment media distribution service ability; Live client sends rich media data stream to the media distributing network system in real time; The beholder receives live person's the invitation or the live page that provides through the live person of browser access through note/instant message/communication modes such as Email, uses Rich Media's player to watch live content then.Utilize the present invention, can Rich Media's resource that terminals such as portable terminal/PC/STB obtain is live to the Internet, make things convenient for the user to watch live content whenever and wherever possible from live person.
Description of the invention provides for example with for the purpose of describing, and is not the disclosed form that exhaustively perhaps limit the invention to.A lot of modifications and variation are obvious for those of ordinary skill in the art.Selecting and describing embodiment is for better explanation principle of the present invention and practical application, thereby and makes those of ordinary skill in the art can understand the various embodiment that have various modifications that the present invention's design is suitable for special-purpose.
