Description
Technical field
The present invention relates to broadcast television technique, particularly a kind of interactive digital broadcast television network system and front end and terminal installation.
Background technology
In the simulation standard wired broadcasting TV epoch, whole network is unidirectional, is equivalent to the tree of a point to multiple spot.Referring to Fig. 1, Fig. 1 is a prior art One-to-All Broadcast TV network structured flowchart, and its structure can be divided into three parts:
Front end 110: comprise professional the volume and broadcast platform 111 and program volume broadcast management system 112, can be described as the program volume broadcasts and transmitting system, broadcast platform 111 by the business volume, after according to different business each program source being edited and processed, compile broadcast management system 112 controls by program, professional volume is broadcast platform 111 and with suitable form program is sent to television network broadcast 120.If secure service is arranged, as long as increase corresponding encryption module.There are not user and higher level service management function.
Television network broadcast 120: generally be optical fiber coaxial cable hybrid network, have middle retransmission unit, but signal is not handled effective transmission of principal security signal.
Terminal 130: comprise professional receiving platform 131, it receives network signal, therefrom restores the business that needs, and the simplest and the most general example is a television receiver.
Along with development of times, this unidirectional wired broadcasting television system manifests more and more significant disadvantages: picture quality is not high, is disturbed easily; Have only the One-to-All Broadcast mode,, also crack easily and spread even encryption is arranged; Do not have Subscriber Management System, be difficult to the authentication of chargeing; Can't carry out abundant interactive service or the like.These shortcomings have caused the broadcasting and TV system to be difficult to form the industrial chain of oneself, are difficult to effective development.
In order to increase the two-way interactive function of television network broadcast, set up powerful user and Business Management Platform simultaneously, runing of radio data system of realization can be managed, Europe DVB (Digit VedioBroadcasting) tissue once proposed the scheme of relevant interactive digital broadcast TV network, and the standard that is used for the Internet has local multiple spot distribution service system (LMDS), Digital European Cordless Telephone (DECT), public switch telephone network (PSTN) and global system for mobile communications (GSM) etc.
Referring to Fig. 2, the interactive broadcast television network configuration framework schematic diagram that Fig. 2 proposes for DVB.This structure is divided 3 parts: front end, communication network, set-top box.
Front end is made of 4 modules:
Broadcasting service supply module 211 (Broadcast Service Provider): in order to broadcasting service to be provided.
Radio network adapter 213 (Broadcast Network Adaptor): in order to the adaptable interface between broadcasting service supply module and the radio network to be provided.
Interactive service supply module 212 (Interactive Service Provider): in order to interactive service to be provided.
Internet adapter 214 (Interactive Network Adaptor): in order to the adaptable interface between the interactive service supply module and the Internet to be provided.
Wherein, the business of interactive service supply module 212 also can be passed through radio network adapter 213, sends to the terminal use with the form of broadcasting.
Communication network divides 2 parts:
Broadcast medium 221 (Broadcasting Delivery Media): in order to the route of transmission of broadcasting service to be provided.
The Internet 222 (Interactive Network): in order to the route of transmission of interactive service to be provided.
Set-top box is divided 3 parts:
Broadcast interface 231 (Broadcast Interface Module): set-top box and broadcast medium's communication interface are provided.
Interactive interface 232 (Intractive Interface Module): set-top box and Internet communication interface are provided.
Unit, machine top 233 (Set Top Unit): other functional units of set-top box.
There is following shortcoming in the interaction schemes that present DVB is proposed:
1, system is rough: from introducing as can be seen, this system only is a frame structure, and functional definition gets very ambiguous and rough, does not almost have the value that realizes.
2, front-end functionality shortcoming: because the Internet has been arranged, the management function of front end needs greatly to strengthen, and this system is a framework, how to realize that specifically front-end functionality does not embody.
3, mutual standard falls behind: the Internet that system proposes is based on PSTN, DECT, LMDS, GSM, and mostly these standards are to belong to the circuit domain technology, have lagged behind current packet domain technology.The realization that these backward technologies directly have influence on system is worth.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of interactive digital broadcast television network system, and corresponding front end and terminal installation are provided.Overcome the structural defect of existing One-to-All Broadcast TV network, make the digital, interactive television network broadcast to be achieved in actual applications.
For achieving the above object, the invention provides a kind of interactive digital broadcast television network system, this system comprises front-end business and sends subsystem and terminal traffic receiving subsystem; Wherein, front-end business sends subsystem, be used for the digital broadcast television service management and the user management of whole system, the management information and the digital broadcast television business information of its generation are sent to the terminal traffic receiving subsystem by data transmission network, receive the management information that produces and send by the terminal traffic receiving subsystem by data transmission network; The terminal traffic receiving subsystem, be used for professional management information and the digital broadcast television business information that sends the subsystem transmission of receiving front-end, and the digital broadcast television business information of receiving exported to the terminal use, and the management information that self produces is sent to front-end business send subsystem.
By technical scheme of the present invention as seen, this digital, interactive television network broadcast system of the present invention and front end and terminal installation have overcome the structural defect of existing One-to-All Broadcast TV network, have realized the application in practice of interactive digital broadcast TV network.
