The apartment house in this embodiment also corresponds to such an Internet apartment, and a router Ri (i = 1, 2,..., N) is connected to a LAN outlet provided in each dwelling unit via a LAN cable Lx. The network I / F unit 8 of the dwelling unit Ai is connected to one of a plurality of ports of Ri via the LAN cable Lx. That is, in the dwelling unit Ai, in addition to a LAN address (private IP address) using the trunk line Ls and the dwelling line Ldi as a transmission path, a LAN address (private IP address) constructed for the purpose of connecting to the Internet NW2 is used. IP address) is assigned, and the former address is used by the dwelling unit line I / F unit 7 via the dwelling unit line Ldi and the trunk line Ls, and the network network I / F unit 8 communicates through the Internet NW2. If so, the latter address is used. Note that the other port of the router Ri is an information home appliance having a network communication function (for example, a television set equipped with a network communication function or a web browser) Xi (i = 1, 2,..., N) is a LAN cable. It is connected via Lx, and it is possible to communicate between the dwelling unit Ai and the information home appliance Xi via the LAN cable Lx and the router Ri.

  Next, an operation when browsing web content with the dwelling unit Ai will be described with reference to the sequence diagram of FIG. In FIG. 4, for simplicity of explanation, a server device (unit on the left side in FIG. 4) is connected to the server unit S in the system configuration diagram of FIG. 1 by the dwelling unit Ai through the dwelling unit I / F unit 7. Device) and the server device (unit on the right side in FIG. 4) with which the dwelling unit Ai communicates via the network I / F unit 8 is described separately.

  First, web contents are distributed from the server device S to each dwelling unit Ai via the dedicated line network NW1 in a time zone in which the bandwidth of the trunk line Ls and the dwelling unit line Ldi is easily secured (for example, a midnight time zone) (S1). In each dwelling unit Ai, the dwelling unit control unit 1 stores the web content distributed from the server device S in the storage unit 5 (S2). Then, when an operation input for starting browsing of web content is accepted in the operation input unit 6 of the dwell unit Ai (S3), the dwell unit control unit 1 reads the web content (homepage HP) stored in the storage unit 5 Then, it is displayed on the display unit 3 by the web browser (S4).

  Subsequently, when an operation input for selecting any link destination in the currently displayed web content (homepage HP) is received by the operation input receiving unit 6 (S5), the dwelling unit control unit 1 selects the selected link. If the previous URL matches the storage location of the web content stored in the storage unit 5, the linked web page is read from the storage location of the web content stored in the storage unit 5 and displayed by the web browser. It is displayed on the part 3 (S6).

  Further, an operation input for selecting any link destination in the web content (homepage HP) is received by the operation input receiving unit 6 (S7), and the URL of the selected link destination indicates the storage location of the web content in the server device S. If it shows, the dwell unit control part 1 will transmit the packet which requests | requires delivery of the said web content (web page) with respect to the said link destination URL from the network I / F part 8 (S8). This packet reaches the server apparatus S via the Internet NW2 via the LAN cable Lx, not the trunk line Ls and the dwelling unit line Ldi. Upon receiving a distribution request from the dwelling unit Ai, the server device S distributes the requested web content to the requesting dwelling unit Ai via the Internet NW2 instead of the dedicated line network NW1 (S9). And the dwelling unit control part 1 displays the web content (web page) delivered from the server apparatus S on the display part 3 by a web browser (S10).

  Thus, when web contents are distributed from the server device S via the private line network NW1 via the trunk line Ls and the dwelling unit line Ldi, for example, a call is made between the dwelling unit Ai of another dwelling unit and the lobby intercom LI. If this is done, a sufficient bandwidth cannot be secured and it takes a lot of time to distribute web contents. On the other hand, if the web content is distributed from the server device S via the Internet NW2 without passing through the trunk line Ls and the dwelling unit line Ldi as described above, for example, between the dwelling unit Ai of another dwelling unit and the lobby intercom LI. Even if a call is made, it is possible to deliver web content in a short time.

  However, there are cases where a resident of a dwelling unit does not have a contract with an ISP (Internet Service Provider), or even if it has a contract with an ISP, the Internet connection service cannot be used due to some trouble.

  Therefore, in the dwelling unit Ai in the present embodiment, an operation input for selecting any link destination in the web content (homepage HP) is received by the operation input receiving unit 6 (S11), and the URL of the selected link destination is the server device. If the dwell unit control unit 1 determines that communication by the network I / F unit 8 is impossible when the storage location of the web content in S is indicated, the web content (web page) with respect to the link destination URL A packet requesting the delivery of is transmitted from the dwelling unit I / F unit 7 (S12). This packet reaches the server device S from the trunk line Ls and the dwelling unit line Ldi via the dedicated line network NW1. Upon receiving the distribution request from the dwelling unit Ai, the server device S distributes the requested web content to the requesting dwelling unit Ai via the private line network NW1 (S13). And the dwelling unit control part 1 displays the web content (web page) delivered from the server apparatus S on the display part 3 by a web browser (S14).

  Thus, according to the present embodiment, when the network I / F unit 8 cannot acquire (cannot communicate with) the web content for any reason, the web content is acquired by the dwelling unit I / F unit 7. There is an advantage that usability is improved by avoiding the situation where it cannot be displayed.

  Next, an operation when browsing web content with the information home appliance Xi will be described with reference to the sequence diagram of FIG.

  First, web contents are distributed from the server device S to each dwelling unit Ai via the dedicated line network NW1 in a time zone in which the bandwidth of the trunk line Ls and the dwelling unit line Ldi is easily secured (S1). The dwell unit control unit 1 stores the web content distributed from the device S in the storage unit 5 (S2). When an operation input for starting browsing of web content is received in the information home appliance Xi (S3), the web browser installed in the information home appliance Xi requests the dwelling unit Ai to distribute the web content. A packet is transmitted (S4). The dwell unit control unit 1 of the dwell unit Ai that has received the packet reads the web content (homepage HP) stored in the storage unit 5 by the web server installed in the dwell unit control unit 1 (S5), The web content is distributed to the information home appliance Xi that is the distribution request source (S6). The web browser of the information home appliance Xi displays the web content distributed from the web server of the dwelling unit Ai on the screen (S7).

  Subsequently, when an operation input for selecting any link destination in the currently displayed web content (homepage HP) is received by the information home appliance Xi (S8), the web browser of the information home appliance Xi selects the selected link. A packet requesting delivery of web content is transmitted to the previous URL (S9). The dwell unit control unit 1 of the dwell unit Ai that has received the packet, if the URL of the link destination matches the storage location of the web content stored in the storage unit 5, the web stored in the storage unit 5 The linked web page is read from the content storage location (S10), and the web content is distributed to the information home appliance Xi that is the distribution request source (S11). The web browser of the information home appliance Xi displays the web content distributed from the web server of the dwelling unit Ai on the screen (S12).

  In addition, an operation input for selecting any link destination in the web content (homepage HP) is received by the information home appliance Xi (S13), and the web browser of the information home appliance Xi performs web access for the selected link destination URL. When a packet requesting distribution of content is transmitted (S14) and the URL of the link destination indicates the storage location of the web content in the server device S, the dwell unit control unit 1 responds to the URL of the link destination. Then, the network I / F unit 8 transmits a packet requesting distribution of the web content (web page) (S15). This packet reaches the server apparatus S via the Internet NW2 via the LAN cable Lx, not the trunk line Ls and the dwelling unit line Ldi. Upon receiving the distribution request from the dwelling unit Ai, the server device S distributes the requested web content to the requesting dwelling unit Ai via the Internet NW2 instead of the dedicated line network NW1 (S16). And the dwelling unit control part 1 delivers the web content (web page) delivered from the server apparatus S to the information household appliance Xi of a delivery request origin (S17). The web browser of the information home appliance Xi displays the web content distributed from the web server of the dwelling unit Ai on the screen (S18). However, if the resident of the dwelling unit is not contracted with the ISP, or if the Internet connection service is not available due to some trouble even if it is contracted with the ISP, it is dedicated from the trunk line Ls and the dwelling unit line Ldi, not via the Internet NW2. What is necessary is just to receive web content from the server apparatus S via the circuit network NW1.

  Thus, according to the present embodiment, the web content for the dwelling unit is distributed from the network I / F unit 8 of the dwelling unit Ai to the information home appliance Xi via the LAN cable Lx. Even without directly accessing the server device S that holds the web content, it is possible to acquire and display the web content for the dwelling unit using the information home appliance Xi.
