Therefore, the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a conceptual diagram for implementing an integrated generation terminal box according to the present invention. As shown in FIG. 2, the installation time, cost, procedure, and the like are simplified by integrating the method previously installed in the household terminal box using the communication modules such as data and broadcasting, respectively, into one module, The home network system based on IoT can be integrated into the space of the home network system.

For this purpose, a first incoming terminal 110 for receiving a Satellite Master Antenna Television (SMATV) optical signal, a second incoming terminal 120 for receiving a CATV broadcast coaxial input signal, A third input terminal 130 connected to the cable for receiving the data optical signal and a fourth input terminal 140 connected to the UTP cable for receiving the UTP data signal and receiving the input signal, And integrates and distributes the respective signals so that the RF integrated signal and the data hub signal can be transmitted to the in-house units 600.

Here, the wireless home gateway 511 functions to integrate the wired coaxial signal and the Ethernet UTP signal with the wireless signal, and is a general technical matter, and therefore, detailed description thereof will be omitted.

3 is a detailed configuration diagram of an integrated household terminal box according to the present invention. As shown in FIG. 3, the integrated generation terminal box receives the SMATV signal through the first input terminal 110 connected to the optical cable.

The first input terminal 110 receives a Master Antenna Television (MATV) and a Satellite Broadcasting Integrated Signal (SAT signal), which are converted into electrical signals by a building distribution center, and receives signals such as TVs or set tops, And a photoelectric conversion receiving module 210 for converting and outputting high frequency signals.

Also, a second incoming terminal 120 is provided for receiving the CATV signal transmitted through the coaxial cable at the building distribution center.

The signal transfer unit 220 selectively connects the RF high-frequency signal output from the photoelectric conversion receiving module 210 or the CATV signal received at the second input terminal 120 to the SMATV and the coaxial line according to the selection of the household subscriber It is possible to switch the route by simple switch operation without the cumbersome work of moving the port of the coaxial cable connected to the house unit 600. Since the switch operation is performed not only at the site but also through the external network connection, It is possible.

The SMATV signal 110 and the CATV signal 120 which are signals input to the optical line or the coaxial line are selected through the signal transfer unit 220 and are converted into the frequency band of the terrestrial signal band of the SMATV signal by the Diplexer filter 1, And the SAT signal and the CATV signal of the satellite intermediate frequency band, respectively.

The signal thus separated and output is distributed to the in-house unit 600, and amplification is required to compensate for the distribution loss occurring in distribution. A first amplification module 240 for amplifying and outputting the SAT signal output from the band separator 230 and a second amplification module 240 for amplifying and outputting the MATV signal or the CATV signal separately output from the band separator 230 240, respectively.

If the satellite signal and the broadcasting signal are amplified at the same time, the signal input power of the amplifier input terminal increases and the amplification degree is limited. Since the low noise amplifier can not be used, the signal quality is lowered due to the harmonic component and noise generated by amplifying the signal. Therefore, the signal is amplified by separating the bands in order to prevent deterioration of signal quality.

The SAT signal amplified by the first amplification module 240 and the MATV signal amplified by the second amplification module 250 are coupled to each other by a band combiner (D2) 260 to be restored to an RF high frequency signal and output .

A first bandpass filter 350 is provided to remove noise of the SAT signal, the MATV signal and the CATV signal band with respect to the switched WiFi radio signal, and a harmonic component and noise that can be generated in the satellite broadcasting band and the MATV / .

In this case, when the noise is not removed, the quality of the WiFi radio signal may be affected due to the combined noise in the broadcast band. The WiFi radio signal with no noise is transmitted to the signal combiner 510 through the impedance matching unit 1 ≪ / RTI >

Here, the signal combiner 510 combines the SAT signal, the MATV signal, the CATV signal band, and the WiFi radio signal with the noise removed by the low pass filter 270 and the first band pass filter 350.

Also, the wired data hub port is connected to the Ethernet port of each domestic unit 600 located in the house.

The signal distributor 520 includes a signal distributor that distributes the combined signal from the signal combiner 510 to one or more RF integrated signals.

A first impedance matching unit is additionally provided between the first band-pass filter 350 and the signal combiner 510.

A second impedance matching unit 430 is additionally provided between the second band pass filter 420 and the signal combiner 510.

4 is a view for explaining the operation of the integrated type terminal box according to the present invention. As shown in Fig. 4 (a), the noise of the MATV signal and the CATV signal band is preferentially removed by the first bandpass filter 350, thereby maintaining the quality of the signal. In order to maintain the quality of the IoT / home wireless signal, the second amplifying module 410 removes the noise of the SAT signal, the MATV signal, the CATV signal, and the WiFi radio signal band with respect to the IoT / A bandpass filter 420 is additionally provided between the third amplification module 410 and the signal combiner 510.

By removing such signals of different frequency bands, it is possible to maintain the respective signal quality by clearly distinguishing MATV / CATV, IoT / home wireless signal, SAT signal and WiFi signal as shown in Fig. 4 (b).

Here, the band of each signal is exemplified as follows: MATV is 54 to 806 MHz, CATV is 54 to 870 MHz, IoT / home radio signal is 900 MHz ISM band, LoRa is 921.9 to 923.3 MHz, and Z- 919.7 to 923.1 MHz, the SAT signal is 950 to 2.15 GHz, and the WiFi signal is 2.4 GHz.
