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

Referring to FIG. 1, an information communication line connection apparatus of a multi-house according to the present invention includes a line distributor 10, a set-top box 2, and a wireless connection apparatus 100.

The home appliance of the apartment house may include a line distributor 1, a set-top box 2, a display device 3, a terminal 4 and a wireless connection device 100, 1 wireless transceiver 100a and a second wireless transceiver 100b.

The line distributor 1 can distribute a line of the wired network n connected to the home via the line entrance part a to provide a network service in the home. Various kinds of wired or wireless networks may be formed in the home, but the networks formed in the home are eventually connected to the wired network n through the line distributor 1 and communicate with the external network such as the internet can do. The first wireless transceiver 100a of the wireless connection device 100 may also be connected to the line splitter 1. The first wireless transceiver 100a of the wireless connection device 100 may be connected to the wired network n, And can transmit and receive data packets and the like from the distributed line.

The terminal 4 may include a wired terminal and a wireless terminal. The wired terminal includes a PC (Personal Computer), a notebook-sized personal computer (PC) , IMT-2000 phone, GSM phone, GPRS phone, WCDMA phone, UMTS phone, MBS phone, and the like. In addition, the wireless terminal may include anything that can perform voice or data communication wirelessly with different terminals, servers, systems, and the like. Here, the wired terminal may be directly connected to the line splitter 1, and the wireless terminals may be connected to the first wireless transceiver 100a and connected to the wired network n through the wireless transceiver 100a.

The display device 3 may be a device for outputting images, images, sounds, and the like. The display device 3 can be connected to the set-top box 2 and can output images, images, sounds and the like according to data packets transmitted by the set-top box 2. Here, the display device 3 may be implemented through a liquid crystal display (LCD), a light emitting diode (LED), an organic light emitting diode (OLED), a plasma display panel (PDP), a cathode ray tube , And anything else that can visually output images or images can be utilized.

The set-top box 2 is connected to the display device 3, and can control images, images, sounds, and the like outputted by the display device 3. Specifically, the set-top box 2 can be connected to an IPTV server providing digital broadcasting, analog broadcasting, Video on Demand (VOD), etc., and transmits content received from the IPTV server to the display device 3 ). ≪ / RTI > Here, the set-top box 2 can provide the contents and the like while performing bidirectional communication with a user viewing the display device 3, rather than unilaterally broadcasting the contents, such as a conventional broadcasting system. That is, according to the set-top box 2, the display device 3 can operate as an IPTV (Internet Protocol Television), and the user can receive various kinds of information such as Internet search, shopping, Service can be provided.

The wireless connection apparatus 100 can wirelessly connect a network between the circuit-breaker 1 and the set-top box 2. [ The position of the circuit-receiving portion (a) is different from the position of the display device 3 designated by the user, since the installation environment in the home differs from that of the circuit-breaker 1 and the set- And may be far away. For example, the circuit-receiving portion (a) in the home may be located in a shoe box, a kitchen, a room or the like, and the display device 3 may be located in a living room. In this case, it is possible to change the position of the circuit-receiving portion (a) by performing the relocation work of UPT (Unshielded Twisted Pair) cable or the like, or to fix the UPT cable to the floor or wall surface in the home, It is necessary to extend and connect the UTP cable to the display device 3. That is, in the related art, there is a difficulty in installing since the line distributor 1 and the set-top box 2 are connected by a wire, and there are problems such as resource consumption and installation aesthetics in the home. On the other hand, when the wireless connection device 100 is used, it is possible to wirelessly connect the line distributor 1 and the set-top box 2, thereby achieving an advantageous effect such as easy connection and maintenance of aesthetics in the home .

Specifically, the wireless connection apparatus 100 may include a first wireless transceiver 100a and a second wireless transceiver 100b. Here, the first radio transceiver 100a may be connected to the line distributor 1, and the second radio transceiver 100b may be connected to the set-top box 2. [ Here, the first radio transceiver 100a may receive a data packet from the circuit-divider 1, and may convert the received data packet into a radio signal form and output it. Then, the second wireless transceiver 100b can receive the wireless signal transmitted by the first wireless transceiver 100a, and transmits the data packet extracted from the wireless signal to the set-top box 2 so that the display device 3 IPTV service can be provided. Here, the first wireless transceiver 100a may provide a network service by transmitting a wireless signal to other terminals 4 located in the home. In particular, the second wireless transceiver 100b may transmit a wireless signal to the second wireless transceiver 100b through a dedicated channel Data packets can be transmitted.

Although the set-top box 2 and the second radio transceiver 100b are shown in different configurations in FIG. 1, as shown in FIG. 2, the second radio transceiver 100b and the set- It is possible to implement the present invention in a single configuration. Here, the second wireless transceiver 100b may be implemented as one module included in the set-top box 2, and may perform the same operation as the second wireless transceiver 100b.

3, the wireless transceiver may include a wired communication unit 110, a wireless communication unit 120, a control unit 130, a conversion unit 140, and an authentication unit 150.

As shown in FIG. 1, the radio transceivers 100a and 100b can be distinguished into a first radio transceiver 100a and a second radio transceiver 100b, respectively, and their operations may be different from each other. First, a specific configuration of the first wireless transceiver 100a will be described.

The wired communication unit 110 may perform wired communication with the wired network n connected to the line distributor 1. [ That is, it can receive the data packet of the wired network n transmitted through the circuit splitter 1 and then transmit the data packet received from the second wireless transceiver 100b to the wired network n. The wired communication unit 110 receiving the data packet from the line distributor 1 can transmit the data packet to the control unit 130. [

The wireless communication unit 120 may perform wireless communication with the second wireless transceiver 100b or the terminal 4 located in the home. That is, the data packets received by the wired communication unit 110 may be converted into radio signals through the wireless communication unit 120 and transmitted to the second wireless transceiver 100b or the terminal 4. [ Here, the wireless communication unit 120 may convert the received data packets into wireless signals having predetermined frequency bands according to an input control signal, and transmit the wireless signals. The first wireless transceiver 100a may operate as a router that performs a wireless signal relay function with respect to the other terminals 4 and the like by utilizing the wireless communication unit 120. [

However, the first wireless transceiver 100a may form a dedicated channel with the second wireless transceiver 100b to ensure QoS (Quality of Service) of IPTV. That is, when the wireless communication unit 120 transmits each data packet in the home, the QoS of the IPTV service can be guaranteed by transmitting the data packet transmitted to the second wireless transceiver 100b through a dedicated channel. Specifically, the dedicated channel can be set in a manner that sets a frequency band of a radio signal for transmitting each data packet differently. For example, in the case of a data packet transmitted to the second wireless transceiver 100b, the data packet can be transmitted through a dedicated channel utilizing a frequency bandwidth of 5 GHz. In addition, a wireless signal can be transmitted using a frequency bandwidth of 2.4 GHz . Therefore, since only the data packet for the IPTV service is transmitted for the frequency band of 5 GHz, it is possible to keep the QoS of the IPTV service constant. Here, the frequency band applied to each data packet by the wireless communication unit 120 is set according to a control signal input to the wireless communication unit 120, and the control signal may be input by the control unit 130.

The control unit 130 may control the overall operation of the first wireless transceiver 100a and may apply a control signal to the wireless communication unit 120 to control the frequency band of the wireless signal transmitted by the wireless communication unit 120 Can be set. Specifically, the control unit 130 can determine the IPTV data packet using the destination address set in the received data packet, and transmits a control signal to the wireless communication unit 120 to transmit the determined IPTV data packet through the dedicated channel . Here, the control unit 130 may apply a control signal to the IPTV data packet to generate a radio signal having a preset dedicated frequency band, and the radio communication unit 120 transmits the IPTV data packet It is possible to transmit the radio signal in the frequency band. Accordingly, the IPTV data packet may be transmitted through a dedicated channel using the dedicated frequency band.

Meanwhile, in order to set up a dedicated channel between the first radio transceiver 100a and the second radio transceiver 100b, it is necessary to perform setting for connection between the first radio transceiver 100a and the second radio transceiver 100b in advance. For this, the control unit 130 may set a fixed MAC address of the first wireless transceiver 100a. The first wireless transceiver 100a may have a dedicated channel for communication with the second wireless transceiver 100b and a base channel for communication with the terminal 40 or the like in the remaining home and may include a MAC address Respectively. Here, the MAC address for the dedicated channel may be set to a fixed MAC address, and the fixed MAC address may be set to the second wireless transceiver 100b. Therefore, the dedicated channel between the first wireless transceiver 100a and the second wireless transceiver 100b can be set to allow connection only to a device having a predetermined fixed MAC address. The connection between the first radio transceiver 100a and the second radio transceiver 100b is not permitted because the connection through the dedicated channel is not allowed for the first radio transceiver 100a and the radio apparatuses other than the second radio transceiver 100b, It is possible to improve security and provide high quality IPTV service.

The control unit 130 may generate authentication information for accessing the first wireless transceiver 100a and may receive the acknowledgment signal from the second wireless transceiver 100b when the response is received from the second wireless transceiver 100b Signal can be transmitted. Here, the authentication information may be generated by the authentication unit 150, and the authentication information may include information on an ID (Identification), a password, and an encryption method of the first wireless transceiver 100a.

Thereafter, when an acknowledgment signal transmitted by the second wireless transceiver 100b is received, the controller 130 may determine that the second wireless transceiver 100b connectable to the first wireless transceiver 100a exists, And may transmit a response signal to the second wireless transceiver 100b. Thereafter, upon receipt of the authentication information request signal from the second wireless transceiver 100b receiving the response signal, the controller 130 may control the second wireless transceiver 100b to transmit the authentication information. Therefore, if the second wireless transceiver 100b then accesses the first wireless transceiver 100a using the authentication information, a dedicated channel can be formed between the second wireless transceiver 100b and the second wireless transceiver 100b.

In addition, the control unit 130 can set a priority order for the data packets received by the wired communication unit 110, and in particular, can assign the IPTV data packet with the highest priority. That is, the control unit 130 can ensure QoS for the IPTV service by controlling the IPTV data packet to be prioritized to the highest priority in the IPTV data packet directed to the second wireless transceiver 100b, and to process the IPTV data packet before other data packets.

In addition, the controller 130 can determine whether a data packet received from the circuit-breaker 1 corresponds to a multicast packet. If the packet corresponds to a multicast packet, the controller 130 determines whether a unicast- . ≪ / RTI > According to the embodiment, it is also possible to convert the multicast type data packet into a unicast type packet using the configuration of the conversion unit 140 separately provided. In the case of converting the multicast type channel stream data into a radio signal and transmitting the same, a quality degradation phenomenon may occur. To prevent this, the controller 130 converts the multicast type data into a unicast type and transmits the unicast type data can do.

Here, the first wireless transceiver 100a only presents the contents of the data packet received from the circuit-splitter 1 to the second wireless transceiver 100b, but conversely, the first wireless transceiver 100a transmits the data packet received from the second wireless transceiver 100b It is also possible to transmit the data packet or the like received from the line splitter 100b to the line splitter 1. Also, the first wireless transceiver 100a may be implemented using a wireless access point (Access Point) that performs a wireless signal relay function for the terminals 4 located in the home.

The second wireless transceiver 100b may include a wired communication unit 110, a wireless communication unit 120, a controller 130, and the like.

The wireless communication unit 120 can receive a wireless signal transmitted by the first wireless transceiver 100a using a dedicated channel. Here, the first radio transceiver 100a may transmit a radio signal having a predetermined dedicated frequency band, and the radio communication unit 120 may receive a radio signal transmitted in the dedicated frequency band. Thereafter, the wireless communication unit 120 may transmit the received wireless signal to the control unit 130.

The control unit 130 can extract the data packet included in the received radio signal and provide the extracted data packet to the wired communication unit 110. The controller 130 sets the fixed MAC address of the second wireless transceiver 100b and then sets the fixed MAC address of the first wireless transceiver 100a to the fixed MAC address of the first wireless transceiver 100a An acknowledgment signal can be periodically transmitted. In addition, when a response signal is received from the first wireless transceiver 100a, the controller 130 may transmit an authentication information request signal to the first wireless transceiver 100a and receive authentication information from the first wireless transceiver 100a The first wireless transceiver 100a can perform connection to the first wireless transceiver 100a using the authentication information.

The wired communication unit 110 may be connected to the set top box 2 and may provide the data packet extracted by the controller 130 to the set top box 2. The settop box 2 may receive the data packet provided by the settop box 2 and may transmit the received data packet to the first wireless transceiver 100a through the controller 130 and the wireless communication unit 120. [

The first wireless transceiver 100a and the second wireless transceiver 100b included in the wireless connection device 100 may be substantially the same devices and may be connected to the first wireless transceiver 100a and the second wireless transceiver 100b, 2 < / RTI > radio transceiver 100b.

That is, the first wireless transceiver 100a may operate as a first wireless transceiver 100a when connected to the line distributor 1 and may operate as a second wireless transceiver 100b when connected to the set-top box 2. [ However, depending on the embodiment, it is also possible to implement the first radio transceiver 100a and the second radio transceiver 100b separately by dedicated devices.
