And the satellite signals can be received simultaneously through the medium.

Referring to FIG. 1, a satellite signal transmission system 10 according to an embodiment may include a satellite 100, a flat antenna 200, an IP allocator 300, and a terminal 400.

The satellite 100 may transmit various information to the earth, for example, by orbiting a predetermined orbit around the earth.

The satellite 100 may be variously classified into communication satellite, broadcasting satellite, meteorological satellite, scientific satellite, navigation satellite, earth observation satellite, technology development satellite, and military satellite depending on the purpose of use.

Various information observed in the satellite 100 can be transmitted to the earth as a radio wave. Hereinafter, a satellite signal, which is a video signal related to a satellite broadcast, will be described as an example.

The satellite signal may be received by a flat antenna (200).

The planar antenna 200 is an antenna having an open surface for receiving a satellite signal. The planar antenna 200 has an advantage that an antenna gain can be increased as compared with a parabola antenna, and the antenna can be less subject to installation.

2 to 4, the planar antenna 200 may include a signal receiving unit 210 and a signal processing unit 220.

2, the planar antenna 200 may be provided in a rectangular parallelepiped shape, for example.

However, the shape of the flat antenna 200 is not limited thereto, and any structure can be used as long as it can efficiently receive satellite signals. For example, the shape of the flat antenna 200 may vary depending on the area where the flat antenna 200 is installed or the antenna gain required for the flat antenna 200.

In addition, the flat antenna 200 may be fixed or not fixed at a position where the antenna installation is required. For example, when the flat antenna 200 is mounted on a moving means such as an automobile or a train, the place where the flat antenna 200 is placed may be changed according to the movement of the moving means.

The signal receiving unit 210 is disposed on the front surface of the flat antenna 200 and can directly receive satellite signals from the satellite 100.

Although not shown in detail, a waveguide that can separate and guide the satellite signal received from the satellite 10 may be formed in the signal receiving unit 210. In other words, the satellite signal received from the front of the signal receiving unit 210 can be transmitted to the inner space of the signal receiving unit 210 through the waveguide.

3 and 4, the signal processing unit 220 may be disposed on the back surface of the flat antenna 200. In addition,

The signal processing unit 220 may include, for example, a signal amplification element 222, a frequency conversion element 224, and an IP conversion element 226.

The signal amplifying element 222 may amplify a satellite signal because the satellite signal received from the signal receiving unit 210 is very weak.

The frequency conversion element 224 transforms the frequency of the satellite signal amplified by the signal amplification element 222 and can convert the frequency to a standardized intermediate frequency. The intermediate frequency is typically normalized from 950 MHz to 2,150 MHz, so that there is device compatibility.

The signal amplifying element 222 and the frequency converting element 224 may be implemented by, for example, a low noise block down converter (LNB). Although not shown in detail, a frequency mixer ) And a local oscillator (LO).

The IP conversion element 226 may be implemented, for example, as an IP (Internet Protocol) server.

The signal amplification element 222 and the satellite signal amplified and frequency converted in the frequency conversion element 224 described above can be transmitted to the IP conversion element 226. [

The IP conversion element 226 can convert the satellite signal into IP data corresponding to the transmission using the IP, for example, demodulate and convert the received satellite signal into IP data. More specifically, the IP conversion element 226 can convert the demodulated RF video signal from either the DVB-S layer or the DVB-S2 layer to an IP (Internet Protocol) transport layer.

The signal processing unit 220 may include a plurality of terminals, and the plurality of terminals may transmit signals processed by the signal processing unit 220 to the various terminals 400.

The plurality of terminals may include a first terminal P1, a second terminal P2, and a third terminal.

The first terminal P1 may output the satellite signal amplified and frequency-converted from the signal amplification element 222 and the frequency conversion element 224 to the first terminal. The first terminal may be, for example, a set top box, and a satellite signal amplified and frequency-converted from the signal amplification element 222 and the frequency conversion element 224 may be transmitted to a TV And the like.

The second terminal P2 can output the IP data converted from the IP conversion element 226 to the second terminal. Here, the second terminal may be an IP allocator 300, for example a router, and the IP data converted from the IP conversion element 226 may be transmitted to the TV, Device 410, and the like.

Also, although not shown in detail, the third terminal can output the IP data converted from the IP conversion element 226 to the third terminal. Here, the third terminal may be a different terminal than the second terminal, for example, if the second terminal is an IP allocator disposed indoors, the third terminal may be an IP allocator placed outdoors. The third terminal may be disposed separately from the flat antenna 200 or may be mounted on the rear surface of the flat antenna 200 adjacent to the signal processing unit 220.

Although it has been described that the plurality of terminals include the first terminal P1, the second terminal P2 and the third terminal, the number of the terminals and the types of equipment to which the terminals are connected may be variously configured .

Since the signal processing unit 220 has a plurality of terminals, the flat antenna 200 can be compatible with existing equipment, and the signal of the flat antenna 200 can be transmitted to various terminals.

Furthermore, a plurality of terminals can supply power to the IP allocator 300 or the terminal 400. Therefore, it is possible to independently supply power to the IP allocator 300 or the terminal 400 connected to the flat antenna 200, so that other power lines can be allocated to the IP allocator 300 or the terminal 400, The terminal 300 or the terminal 400 may be operated.

In addition, although not specifically shown, a plurality of guide elements may be provided in the signal processing unit 220 in order to transmit signals between the signal receiving unit 210 and the signal processing unit 220 described above.

The plurality of guiding elements may include a first guiding element and a second guiding element.

The first guiding element may guide the received satellite signal to the signal amplifying element 222 and the frequency converting element 224 and the second guiding element may direct the signal amplifying element 222 and frequency It is possible to guide the satellite signal that has been amplified and converted from the conversion element 224 to the IP conversion element 226. [

Furthermore, it is of course possible to further include a third guiding element capable of directing the satellite signal received by the signal receiving section 210 to the plurality of guiding elements directly to the IP converting element 226.

In this way, the signal processing unit 220 can be mounted on the back surface of the flat antenna 200, thereby preventing the signal processing unit 220 from being exposed to the outside, and the aesthetic appearance can be improved.

In addition, since the signal receiving unit 210 and the signal processing unit 220 are integrally provided, the flat antenna 200 can be made thinner and can have a compact structure, It is possible to prevent the loss of the satellite signal and further improve the antenna gain.

For example, when the signal receiving unit 210 and the signal processing unit 220 are separately provided, the signal receiving unit 210 and the signal processing unit 220 must receive a signal by wire or wireless, And it may be limited by space when the flat antenna 200 is installed.

The flat antenna 200 including the signal receiving unit 210 and the signal processing unit 220 may be connected to the IP allocator 300.

The IP allocator 300 is a hardware and software device that connects two or more networks and enables communication from one communication network to another communication network. The IP allocator 300 may have a function of converting an address between the networks or converting the protocol to an appropriate one.

Specifically, the IP allocator 300 may forward the satellite signal converted by the IP conversion element 226 to the assigned IP address, and output the satellite signal from the terminal 400.

For example, when a plurality of terminals are provided, a first IP address may be assigned to the first terminal, a second IP address may be assigned to the second terminal, and a third IP address may be assigned to the third terminal.

The signal output from the signal processing unit 220 may be transmitted to the various terminals 400, for example, a mobile device, a set top box, a TV, or the like through the IP allocator 300.

5, the planar antenna 200 and the IP allocator 300 may be connected by a single thin coaxial cable. The signal from the signal processor 220 of the planar antenna 200 through the cable may be transmitted to the IP allocator 300 Lt; / RTI > can be transmitted.

For example, when the signal processing unit 220 is disconnected from the flat antenna 200, particularly when the signal amplifying element 222, the frequency converting element 224 and the IP converting element 226 are separated, The signal amplification element 222 and the frequency conversion element 224 need to be connected to the IP conversion element 226 by four cables in order for the four signals to be transmitted through the frequency conversion element 222 and the frequency conversion element 224. [

Therefore, the signal processing unit 220, particularly the signal amplifying element 222, the frequency converting element 224 and the IP converting element 226 are integrally provided in the flat antenna 200, (Not shown).

Although the IP allocator 300 is described as being connected to the flat antenna 200 or the terminal 400 by wire, the IP allocator 300 may be connected to the flat antenna 200 or the terminal 400 wirelessly. Of course.

Also, the IP allocator 300 may be mounted inside or outside the flat antenna 200. For example, the IP allocator 300 may be disposed separately from the flat antenna 200, or may be mounted on the back surface of the flat antenna 200 separately from the signal processing unit 220, or may be embedded in the flat antenna 200, And may be included in the processing unit 220.

Alternatively, when a plurality of IP allocators 300 are provided, some of the IP allocators 300 may be located in the inner space of the flat antenna 200, and some of the IP allocators 300 may be disposed on the flat antenna 200, respectively. In other words, the flat antenna 200 has the function of assigning an IP address to the terminal, or the signal transmitted from the flat antenna 200 can be assigned an IP address to the terminal in a separate IP allocator.

As described above, the IP allocator 300 may be configured in various ways for the flat antenna 200.

In particular, when the IP allocator 300 is embedded in the flat antenna 200 and included in the signal processor 220, the IP allocator 300 may be wirelessly connected to the flat antenna 200 or the terminal 400 Lt; / RTI >

5 shows that the planar antenna 200 is placed outdoors and the IP allocator 300 is disposed in the room, the IP allocator 300 is mounted on the back surface of the flat antenna 200, It is to be understood that the device 300 may also be disposed outdoors. In other words, the IP allocator 300 can be deployed both indoors and outdoors.

A plurality of terminals 400 may be connected to the flat antenna 200 or the IP allocator 300.

The plurality of terminals 400 may include a mobile device 410, a set top box 420, a TV 430, or the like, as described above.

In the case of the mobile device 410, a signal transmitted from the IP allocator 300 may be relayed through the application A and output on the terminal.

In other words, the signal transmitted from the IP allocator 300 through the application A can be converted or executed so that the signal can be output from the mobile device 410.

In the case of a set top box 420 or a TV 430, a signal transmitted from the IP allocator 300 may be transmitted to the TV 430 through the set top box 420.

The set-top box 420 is connected to the TV 430 and receives signals received from the outside to appropriately convert the signals to display the contents on the TV 430. The set-top box 420 generally includes a video-on-demand (VOD) It is necessary to use next generation interactive multimedia communication service such as network game.

However, the plurality of terminals 400 are not limited thereto, and various terminals may be included.

In particular, referring to FIG. 6, satellite signals may be simultaneously transmitted through various media in the home through the satellite signal transmission system 10 according to an exemplary embodiment.

Specifically, a signal is transmitted from the flat antenna 200 to the IP allocator 300, and a signal can be transmitted from the IP allocator 300 to the terminal 400 by the home wired and wireless network system.

For example, signals may be transmitted from the IP allocator 300 to at least one gaming console, at least one TV, or at least one PC via a local area network (LAN).

Alternatively, a signal may be transmitted from the IP allocator 300 to at least one smartphone or at least one tablet PC via a wireless local area network (WLAN).

In other words, different signals or the same signals can be simultaneously transmitted from the IP allocator 300 to the various terminals 400, for example, eight terminals, in the area where the network is established, that is, wired or wireless.
