Description
Affiliated technical field
The present invention relates to a kind of household electrical appliance, especially, is a kind of received television program that is used for, and exports to the STB of television set.
Background technology
In the DTV networking of popularizing at present, requisite corollary equipment when STB is the television set received television program.STB is used for the signal in each radio station of digital television signal end is carried out go-on-go, will count the signal of telecommunication afterwards again and be converted into the mould signal of telecommunication and export to television set, thereby make television set can be transferred to each radio station as required.
Yet present STB situation is, a STB can only be joined a television set, the improvement of Along with people's condition, and present family has a plurality of television sets usually, if STB of each television set configuration, wiring is trouble comparatively, and cost is also bigger; Just because of this, in present many average families, a plurality of television sets only dispose STB one or two, and wherein some television set can only be received seven or eight radio station from original simulated television network, and this is very disadvantageous for users.
Summary of the invention
To the problems referred to above, the object of the present invention is to provide a kind of family midsequent STB, this STB can provide different TV programme for simultaneously a plurality of television sets, and can reduce family's wiring to a great extent.
The technical solution adopted for the present invention to solve the technical problems is: this family's midsequent STB comprises primary module and secondary module; Said primary module comprises a digital to analog converter that is used for several signals of telecommunication of digital television signal end are converted into the mould signal of telecommunication; Connect two after this digital to analog converter to raise the platform module, each is transferred and comprises a resonance modules and a resonance control receiver module that is used to adjust said resonance modules resonance frequency in the platform module; The quantity of said secondary module equates with said accent platform module; Be plugged in the TV input interface of television set; Said secondary module comprises a resonance control module that is used to control said resonance control receiver module; And a resonance receiver module that is used to receive said resonance modules signal, this resonance receiver module through behind amplification module to the television set outgoing television signal; The operating frequency of said resonance modules resonant control receiver module is always different frequency range, and the operating frequency of the said resonance control module in each said secondary module is different.
Further, said resonance control module is associated with the infrared receiving terminal of television set, through the television set IR remote controller, can control said resonance control module.
Further, in the said primary module, be connected to amplifying circuit between said digital to analog converter and the said accent platform module, amplify with signal to the digital television signal end.
Further, in the said primary module, the resonance signal of said resonance modules is through the resonant antenna emission, and said resonance receiver module receives the resonance signal by said resonance modules through resonant antenna.
Beneficial effect of the present invention is: this family's midsequent STB is when work; Can entreat in the family; Arrange a primary module like parlor place, this primary module all converts severals signals of telecommunication of digital television signal end to the mould signal of telecommunication through said digital to analog converter, and flows to each accent platform module respectively; Wherein, Absorbed by resonance modules with the identical mould signal of telecommunication of resonance modules frequency described in the accent platform module, and be converted into the said secondary module of form of electromagnetic wave transmission to each TV set terminal by resonance modules, secondary module can be to the television set outgoing television signal after receiving this mould signal of telecommunication; And through resonance control module in each said secondary module and the control of the resonance in said primary module receiver module, can realize the adjusting to the resonance frequency of resonance modules in the primary module, thereby can realize transferring the platform function; This STB can provide different TV programme for simultaneously a plurality of television sets, and can reduce family's wiring to a great extent.
Description of drawings
Fig. 1 is the electrical structure diagram of this family midsequent STB.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
In the embodiment shown in fig. 1; This family's midsequent STB comprises primary module 1 and secondary module 2; Said primary module 1 comprises a digital to analog converter 101 that is used for several signals of telecommunication of digital television signal end are converted into the mould signal of telecommunication; Connecing first after this digital to analog converter 101 transfers platform module and second to transfer the platform module; Said first transfers platform module and second to transfer comprises first resonance modules 105, first resonance control receiver module 104 respectively in the platform module, and second resonance modules 103, second resonance control receiver module 102, and each said resonance control receiver module is used to adjust the resonance frequency of its pairing resonance modules.
The quantity of said secondary module 2 equates with said accent platform module; For principle of specification compactly; Only show a secondary module 2 among Fig. 1; This pair module 2 is plugged in the TV input interface of television set, and said secondary module 2 comprises first a resonance control module 201 that is used to control said first resonance control receiver module 104, and first a resonance receiver module 202 that is used to receive said first resonance modules, 105 signals; This first resonance receiver module 202 connects output 204 through an amplification module 203 backs, to the television set outgoing television signal; The operating frequency of said first resonance modules 105 and first resonance control receiver module 104 is always different frequency range, and this is in order to guarantee that control signal and TV signal are unlikely to cause mutual interference mutually; And; The operating frequency of the resonance control module in each said secondary module is different; That is respectively transfer the platform module in the said primary module 1; As in the present embodiment first transfer first resonance control receiver module 104 that platform module and second transfers the platform module and second resonance to control receiver module 102 operating frequency different, this is in order to guarantee that each television set operating side do not disturb for the control signal of said primary module 1 mutually.
