For above-mentioned purpose of the present invention, feature and advantage can be become apparent, below in conjunction with accompanying drawing the specific embodiment of the present invention is elaborated, wherein:
Fig. 1 illustrates according to multimedia transmission agreement flow process of the present invention;
Fig. 2 illustrates the multimedia transmission method flow chart of one embodiment of the invention;
Fig. 3 illustrates the multimedia transmission method flow chart of another embodiment of the present invention;
Fig. 4 illustrates the BDOM file format.
Embodiment
In the following embodiments, multimedia file and control information adopt a kind of BDOM (Bytedocument object model) transfer files to transmit, and wherein the type according to file is divided into two modules.
Basic block: the little files of data volume such as control logic, text, picture are deposited in the BDOM file.
Extension blocks: video, audio file are because data volume is bigger, can select the form deposited, the present invention does not limit the concrete transformat of video, audio file, video, audio file both can directly leave in the BDOM file, also can transmit by the mode of wired network broadcasting, equally also can use the mode of IP network to transmit, even can leave in advance in the local storage.When video, audio file do not transmit by the BDOM file, the BDOM control information will be operated video, audio file by filename.
One embodiment of the invention propose a kind of can the bearing multimedia file, multimedia control, and the digital TV multimedia transmission plan of the transmission of polytype data such as Play Control, this method supports head end immediately to the control of terminal multi-media operation simultaneously.Fig. 1 illustrates according to multimedia transmission agreement flow process of the present invention; Fig. 2 illustrates the multimedia transmission method flow chart of one embodiment of the invention.Below with reference to the multimedia transmission method of describing present embodiment illustrated in figures 1 and 2.
In the transmission course, above-mentioned basic block and extension blocks are separately transmitted, can carry different bottom host-host protocols, can issue by the mode of wired network broadcasting such as basic block, and extension blocks can be passed through the various host-host protocols transmissions of IP (Internet Protocol) network.The set-top box end can read the control information in the BDOM file and dispose the control corresponding module by corresponding control interfaces, can carry out various multimedia operations automatically according to the control logic in the BDOM file when module is carried out.
At first in step 301, in the head end 100 (head end) of digital television system, use agreement maker 110 is imported corresponding object and control logic, generates transfer files (as the BDOM file), and it comprises basic block 120 at least.Basic block can comprise control logic, text, picture.If video, audio file need use extension blocks 130 (step 302), then be ready to corresponding file (step 303).
Secondly,, use optional file transfer protocol (FTP) 150, basic block and extension blocks are issued to terminal 200 (as set-top box) respectively in step 304.In an embodiment of the present invention, file transfer protocol (FTP) comprises various wire transmission agreements and IP network host-host protocol.
Wherein, the transmission of basic block 120 and extension blocks 130 can be asynchronous transmission, need not synchronously.And, can select only to send basic block 120 in the transmission course, perhaps only send extension blocks 130.When adopting asynchronous transfer mode, the extension blocks that data volume is big can send at the backstage select time, and after extension blocks received, the basic block that data volume is little can transmit control in real time.
In another embodiment, the extension blocks in the BDOM file can store the local storage 230 (as hard disk, internal memory) of terminal 200 in advance in other mode into.
Afterwards, in step 305, the protocol resolver 210 in the STB terminal 200 can be resolved the BDOM file, creates or configuration control corresponding module (or control) 220.And if the content of transmission comprises extension blocks 130, then the content of extension blocks will directly leave in the local storage 230 (step 306).
Wherein, control module 220 will adopt the control mode of stipulating in the new BDOM file after being disposed by protocol resolver 210.
The form of BDOM file please refer to shown in Figure 4, and data wherein are divided into: resource items, window, assembly, element etc.Resource items comprises picture, video, audio file etc.; Element comprises text, control logic etc.The parametric description of BDOM file is as follows:

Control logic can order the broadcast of control of video, audio file by above-mentioned these.On the other hand, other above-mentioned multimedia files, for example text, picture etc. can be updated in the application corresponding module when receiving automatically, can see behind application start.
Another embodiment of the present invention provides the scheme of a kind of multimedia transmission and broadcast.Be described referring now to Fig. 1 and Fig. 3.
At first in step 401, in the head end 100 (head end) of digital television system, use agreement maker 110 is imported corresponding object and control logic, generates transfer files (as the BDOM file), and it comprises basic block 120 and extension blocks 130.Control logic can be comprised in the basic block 120, also objects such as text, picture can be comprised.
Secondly,, use optional file transfer protocol (FTP), basic block and extension blocks are issued to terminal 200 (as set-top box) respectively in step 402.In an embodiment of the present invention, file transfer protocol (FTP) comprises various wire transmission agreements and IP network host-host protocol.
Wherein, the transmission of basic block 120 and extension blocks 130 can be asynchronous transmission, need not synchronously.And, can select only to send basic block 120 in the transmission course, perhaps only send extension blocks 130.When adopting asynchronous transfer mode, the extension blocks that data volume is big can send at the backstage select time, and after extension blocks received, the basic block that data volume is little can transmit control in real time.
Afterwards, in step 403, the protocol resolver 210 in the STB terminal 200 can be resolved the BDOM file, creates or configuration control corresponding module (or control) 220, wherein can comprise control logic.
In step 404, and the content of extension blocks will directly leave in the local storage 230.
In step 405, control module 220 can these order the broadcast of control of video, audio file according to the aforesaid PeriodPlayMultiMedia, the PlayMultiMedia that comprise in the control logic.
Therefore, during the advantage of present embodiment, the extension blocks (big capacity) that comprises the basic block (low capacity) of control logic and comprise video, audio file can separately be transmitted, and multimedia file has guaranteed the quality that the user watches all in this locality when carrying out the multimedia controls playing.
In sum, the multimedia transmission method of the above embodiment of the present invention has the following advantages compared to existing technology:
1, various multimedia files be can transmit, video, audio file comprised, text, logic, picture etc., and expansion is easily;
2, owing to adopt asynchronous transfer mode, the extension blocks that data volume is big can send at the backstage select time, and after extension blocks received, the basic block that data volume is little can transmit control in real time.
3, can use by sending basic block control and changing whole multimedia at head end.
4, owing to the opening of this method, host-host protocol can adopt any file transfer mode, has expanded compatibility greatly.
5, owing to adopt the elementary cell of file as control, multimedia file has guaranteed the quality that the user watches all in this locality when carrying out the multimedia controls playing.
Though the present invention discloses as above with preferred embodiment; right its is not in order to qualification the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when can doing a little modification and perfect, so protection scope of the present invention is when with being as the criterion that claims were defined.
