In this case, the invention relates to an Internet connection system that enables all households in a condominium to connect to the Internet through a contract with one provider.

[0002]

2. Description of the Related Art Conventionally, in buildings such as condominiums having a large number of households, when residents of each household use the Internet, they individually contract with a provider and use a telephone line or the like to connect to the Internet. And had internet connection.

[0003] In addition, since it takes time to transmit and receive data when a telephone line is used, a LAN is constructed and a communication line for the LAN is connected to a conventional television so that high-speed communication can be performed. Some condominiums are independent of the cable wiring.

Further, Japanese Patent Application No. Hei 8-2857 filed for patent application
85 and Japanese Patent Application No. 8-285786.

The LAN / TV co-listening system unit does not cause the LAN signal and the signal of the receiver of the television or the like to interfere with each other, so that it can be used in a coaxial cable used by a television or the like wired in an existing building. It can be transmitted.

[0010] By using the LAN / TV co-listening system unit, the LAN can be connected to a building such as a condominium independently of the cable wiring of a TV or the like.
Therefore, high-speed communication can be performed without wiring.

[0011]

However, high-speed communication is possible by constructing a telephone line with a LAN and using a unit for a LAN / TV co-listening system. However, when using the Internet, a large condominium cannot be used. Each household in the condominium had to individually sign up for a connection with a provider, an Internet provider.

Further, there is a problem that it is not sufficient to enable high-speed communication of LAN signals when using a LAN by connecting to the Internet by making a contract with a provider.

Accordingly, the present invention provides a contract with one professional diver, one of the connection companies, by wiring a whole building such as an apartment building by using a unit for a LAN / TV co-listening system. Many households of large condominiums can use the Internet at the same time, and the building manager can send notices such as circular notices in the building.
Can be distributed using AN, LAN if desired
It is an object of the present invention to provide an Internet connection system that can use mutual data on a door-to-door basis in a building where is constructed.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to connecting a server, a router, a unit for at least one LAN / TV co-listening system, a repeater, and a computer. The configuration of the Internet connection system is a feature.

[0015]

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
The Internet connection system using the N / TV co-listening system unit will be described in detail.

FIG. 1 shows an overall view of the present invention. As shown in FIG. 1, the building 2 includes a server 10, a router 5, a firewall 9, and a computer 11 provided in each house. The server 10, the router 5 and the computer 11 provided in each house are connected by a cable. 8 is used to construct a LAN, and the server 10 or the router 5 is connected to the provider 4 and the Internet 3 using the connection line 6 via the firewall 9.

The connection line 6 may be connected by a dedicated line to enable high-speed communication. The connection line 6 is
Wireless may be used.

The firewall 9 is provided between the outside and the building and between network-compatible devices provided in each door and the network, so that a hacker (a person trying to break into a computer) or the like breaks into a private network. This is provided to prevent

The router 5 is a device for managing connections from a large number of households in an apartment to the Internet 3.

Usually, when one contract is made with one provider, one IP address is given. Therefore, while one house is connected to the Internet, no other computer can use the Internet.

However, the router 5 described above is a router 5 that can dynamically assign an IP address each time when one computer is connected to the Internet and another computer is connected to the Internet. That is.

By using the router 5, the LA
In the building 2 constructed in N, even if there are a large number of households in the apartment, they can be used simultaneously by contracting with a professional connection provider, Pro Diver, for the entire apartment.

The server 10 solves the trouble by monitoring the normal communication state of the computer constructed on the LAN, and constructs a system according to the request of each door.

FIG. 2 shows a system diagram in a building. FIG.
As shown in the figure, the wiring in the building 2 divides each house into a certain block, and the wiring connected to the block is distributed from the router 5 and connected. When an extension of a cable or the like is necessary, a repeater may be used as shown in 9a of FIG.

FIG. 3 shows a wiring diagram of the number of households in an apartment. As shown in FIG. 2, the wiring of the cable 8 in the building 2 of the condominium is distributed to each house by the router 5, and as shown in FIG. 3, the wiring of the cable 8 distributed to each household is divided into each household. The LAN wiring 8a and the T
It is distributed to the V wiring 8b.

The LAN wiring 8a is connected to the computer 11
And the TV wiring 8b is connected to a TV or the like (VHS, UH
F, BS, CS, etc.).

Further, in order to prevent intrusion into a private network, the computer 11 is connected to a LAN.
./TV TV system 9b. The firewalls 9 may not be provided.

As described above, the Internet connection system using the LAN / TV co-listening system unit according to the present invention comprises a server 10 and a router 5 through a connection line 6 and a cable 8 as shown in FIGS. A LAN / TV co-listening system unit 9b, a repeater 9a, a firewall 9, and a computer 11
Is connected to the system.

Next, the flow when connecting to the Internet will be described. When connecting to the Internet, as shown in FIG. 1 to FIG. 3, a computer 11, 11, 11,... 9b, a cable 8, a repeater 9a, a server 10, a router 5, and a connection line 6 are connected to the Internet 3 from a contracted provider 4 to perform communication.

At this time, in the building 2, it is conceivable that a plurality of people connect at various times, so that even if a plurality of people connect at the same time, it is necessary to dynamically assign an IP address so that connection can be established. By installing a router 5 that can be connected, connection becomes possible.

Further, since the inside of the apartment building 2 is constructed by LAN, it is possible to share data among the households in the apartment. In this case, intrusion is restricted by a personal identification number or the like, and data and the like can be mutually exchanged within a building of an apartment.

Further, conventionally, the contact from the manager of the apartment building or the like has been made on a bulletin board or the like, but it is also possible to quickly distrust the households in the apartment by the distribution by LAN or the like.

[0033]

Since the present invention has the above-described configuration, the following effects can be obtained. First, it is very economical as a whole because each house does not need to make a contract with a provider on its own and Internet applications need only be made in one building as a representative.

Second, when a building manager or the like conveys a message or the like, a bulletin board or the like is not required, and the message can be directly delivered to each house by using a LAN.

Third, since the building is constructed with a LAN, data can be shared and mutually used.
