Description
Technical field
The present invention relates to a kind of home gateway, particularly a kind of home gateway that is applied to power carrier communication.
Background technology
Home gateway is to receive communication signal from family's external network, by home network signal is passed to each network equipment of household internal again.At present, traditional home gateway mainly plays the effect that broadband network inserts, and the network equipment that is household internal provides access and interconnected.There are the following problems for traditional home gateway: output signal needs the various types of signal line, and it is numerous and diverse to connect up, the cost height; Do not have the access of telephone network and cable television network, there is no the function that digital signal is handled.
Summary of the invention
The object of the present invention is to provide a kind of home gateway that is applied to power carrier communication, this telephone signal and computer network signal that is applied to the home gateway output of power carrier communication transmits by power line, need not within the family, portion arranges various holding wires, and this home gateway that is applied to power carrier communication also has the digital TV decoding function, realized TV interaction, the fusion of telephone network and internet.
The present invention is achieved in that a kind of home gateway that is applied to power carrier communication, and it comprises digital television decoding module, network routing module and power modulation demodulation module; Described digital television decoding module is used to connect the TV signal circuit of television set and family outside; Described digital television decoding module also is connected with described network routing module; Described network routing module is used to connect the network and the home network device of family outside, and described network routing module is connected with home network device by power line through described power modulation demodulation module; Described power modulation demodulation module is used to connect the telephone signal circuit of telephone set and family outside, and described power modulation demodulation module is connected with telephone set by power line.
Described home network device comprises computer, and described computer is connected in family's power line by electric power modem, and described telephone set is connected in family's power line by electric power modem.
This home gateway that is applied to power carrier communication has been realized TV interaction, the fusion of telephone network and internet.This telephone signal and computer network signal that is applied to the home gateway output of power carrier communication transmits by power line, need not within the family, portion arranges various holding wires, this home gateway that is applied to power carrier communication also has the digital TV decoding function simultaneously, make the user not only can watch the program of cable TV, and can be by the video on demand program.
Description of drawings
Fig. 1 is applied to the home gateway connection diagram of power carrier communication for the present invention.
Embodiment
Specify the home gateway that is applied to power carrier communication of the present invention below in conjunction with accompanying drawing.
Consult Fig. 1, Fig. 1 is applied to the home gateway connection diagram of power carrier communication for the present invention.Home gateway 6 of the present invention comprises digital television decoding module 1, network routing module 2 and power modulation demodulation module 3; Described digital television decoding module 1 is used to connect the TV 5 of home network inside and the TV signal circuit of family outside; Described digital television decoding module 1 also is connected with described network routing module 2; Described network routing module 2 is used to connect the network of family outside and the home network device of household internal, and described network routing module 2 is connected with the home network device of household internal by power line 7 through described power modulation demodulation module 3; Described power modulation demodulation module 3 is used to connect the telephone set 11 of household internal and the telephone signal circuit of family outside, and described power modulation demodulation module 3 is connected with the telephone set 11 of household internal by power line 7.
The TV signal of cable television network 12 transmission sends to TV 5 through digital television decoding module, and TV 5 can be simulated television, also can be IPTV.The digital signal of Internet transmission is transferred to digital decoding module 1 through network routing module 2, digital decoding module 1 converts digital signal to analog signal, it is to the reduction of decoding through the image of digitalization compressed and voice signal, produce the video and audio signal of simulation, and be transferred to TV 5 or stereo set.The user can also can send the program request order to network by TV 5 (as IPTV), realizes TV interaction.
The digital signal of internet 13 transmission is after 2 outputs of network routing module, and again through 3 modulation of power modulation demodulation module, the mode that makes digital signal pass through carrier wave is transmitted on family's power line.Portion within the family, the electric power modem 8 that is connected on family's power line 7 demodulates digital signal from the electric power wave that power line transmits, the information that computer 9 is received from the internet by electric power modem 8.On the other hand, the information signal that computer 9 sends is modulated through electric power modem, and transmits on family's power line 7 by the mode of carrier wave, passes through the demodulation of the modulation module 3 in the home gateway 6 again, through network routing module 2, information is sent on the internet 13.Therefore, portion within the family, the user need not to arrange separately netting twine again.
The voice signal of public switch telephone network 4 is by 3 modulation of power modulation demodulation module, and the mode that makes voice signal pass through carrier wave is transmitted on family's power line 7.Portion within the family, the voice modem 10 that is connected on family's power line demodulates voice signal from the electric power wave of family's power line 7 transmission, make telephone set 11 receive voice signal by voice modem.On the other hand, the voice signal that household internal phone 11 sends is by the modulation of voice modem 10, transmit on family's power line 7 by the mode of carrier wave again, send in the public switch telephone network 4 after power modulation demodulation module 3 demodulation in home gateway, realize sending of telephone signal.Therefore, portion within the family, the user need not to arrange separately telephone wire again.In addition, this phone is if IP phone, and telephone signal sends in the internet by the network routing module, thereby gets in touch with intercommunication side through modulation, realizes conversation.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
