[Detailed description of the invention]
Fig. 1 is a kind of process signal of data broadcasting method based on IP over DVB applied to set-top box of the present invention Figure.
[specific embodiment]
To make the purpose of the present invention, technical solution and advantage are more clearly understood, with reference to the accompanying drawings and embodiments, to this Invention is further elaborated.It should be appreciated that specific embodiment described herein is used only for explaining the present invention, not For limiting the invention.
Referring to Fig. 1, a kind of data broadcasting method 1 based on IP over DVB applied to set-top box of the present invention includes Following steps,
S1: data information is packaged in by DSMCC (Digital Storage using multi-protocol encapsulation mode (MPE) Media-Command and Control) fragment Datagram_Section inside configuration；Guarantee segmentation table ID is 0x3E, Stream type domain (stream type) is 0xA；
S2: obtaining the IP datagram text that must be forwarded using the transmitting terminal of set-top box, and message address and MAC difference broadcast is arranged Mode is encapsulated into MPEG-2TS data packet, by satellite Modem, by digital signal transition at high frequency analog signals, Xiang Wei Star transmitting；
S3: using set-top box receiving end by antenna assembly from external satellite receive signal, it is demodulated and demultiplex by High frequency analog signals are converted into digital signal, and according to the pre-set information of set-top box (MAC) by controlling program to data It is filtered, frame processing, decapsulation recombinates IP packet from MPEG-2TS data packet；After receiving IP packet, according to privately owned Network data agreement, classification shows IP data content on the tv screen；
S4: the data broadcasting based on IP over DVB is completed.
Data information is packaged in DSMCC (Digital by using multi-protocol encapsulation mode (MPE) by the application Storage Media-Command and Control) fragment Datagram_Section inside configuration；Guarantee segmentation table ID For 0x3E, stream type domain (stream type) is 0xA, provides IP traffic for set-top box, provide for users in addition to DVB Richer free nets Instant-Counseling information other than audio-video service, enriches set-top box functionality, promotes competitive advantage, is based on This programme can realize business revenue, also can provide subscription function according to national region accurately to user's advertisement category information, to Terminal user provides the information subscribing function of charge.
Preferably, the set-top box is previously provided with unique hardware equipment information, which includes region Code | block code | Customer ID；Terminal user provides the hardware equipment information and subscribes to value-added service.
Preferably, the data information type in the step S1 includes text, picture, multimedia, control data；Receiving end Device authentication information；Data View size；Data View position；Whether it is locally stored；Valid data.
IP traffic is transformed into mpeg 2 transport stream (TS) by encapsulation and multiplexing by this programme, makes digital video broadcasting (DVB) system becomes a kind of carrier for supporting Internet application.Multi-protocol encapsulation mode (MPE) is used to encapsulate data to inherit From the Datagram_Section structure of DSMCC (Digital Storage Media-Command and Control) fragment, Segmentation table ID is 0x3E, and stream type domain (stream type) is 0xA, is effectively mapped in the load of TS packet and is transmitted.It is logical Cross the unicast that MPE realizes protocol data packet, multicast and broadcast transmission.
Transmitting terminal obtains the IP datagram text that must be forwarded, and message address is arranged and MAC distinguishes broadcast mode, is encapsulated into MPEG-2TS data packet, by satellite Modem, by digital signal transition at high frequency analog signals, to satellite launch (transmitting equipment A set of common two-way satellite network service must be bought to satellite operator).
By antenna assembly from satellite received signal, high frequency analog signals are converted by demodulated and demultiplexing for receiving end Digital signal, and data are filtered by controlling program according to the information of set-top box default setting (MAC), frame processing, solution Encapsulation, recombinates IP packet from MPEG-2TS data packet.After receiving IP packet, according to privately owned network data agreement, in electricity Classification display IP data content on screen curtain.
Compared with prior art, a kind of data broadcasting method 1 based on IP over DVB applied to set-top box of the present invention Data information is packaged in DSMCC (Digital Storage Media- by using multi-protocol encapsulation mode (MPE) Command and Control) fragment Datagram_Section inside configuration；Guarantee segmentation table ID is 0x3E, stream type Domain (stream type) is 0xA, provides IP traffic for set-top box, is provided other than the service of DVB audio-video for users Richer free nets Instant-Counseling information, enrich set-top box functionality, promoted competitive advantage, be based on this programme, can basis National region accurately to user's advertisement category information, realizes business revenue, also can provide subscription function, provides receipts to terminal user The information subscribing function of taking.
The embodiments of the present invention described above are not intended to limit the scope of the present invention.It is any in the present invention Spirit and principle within made modifications, equivalent substitutions and improvements etc., should be included in claim protection model of the invention Within enclosing.
