S56 and FIG. 6 (a)). Then, by pressing the send button, the dynamic DNS service server 3 searches for and notifies the host name (S57 in FIG. 5 and FIG. 6B). The user who receives the host name can start the video browsing page by clicking on the host name displayed on the monitor, and can receive and monitor the video and audio distributed by the network device. (S59 in FIG. 5 and FIG. 6C).

  If the user inputs the serial number once, for example, it is registered in a favorite or the like, so that it is not necessary to input again thereafter. For the host name used when starting the video browsing page, for example, a two-dimensional barcode storing a URL (Uniform Resource Locator) is pasted in the vicinity of the network device 1 without opening the monitor screen each time. When the mobile terminal 4 captures the image, it can be smoothly connected to the dynamic DNS service server 3.

  As described above, according to the present invention, the dynamic DNS service server 3 determines the global IP address and host name of the network device 1 according to the host name generated based on information unique to the network device 1 transmitted from the network device 1. In this way, the DNS information is updated and the IP environment setting of the network device 1 is automatically performed, so that the dynamic DNS service can be performed without any troublesome setting work for the user. Can be used. Therefore, for example, the user can easily access the network device 1 such as a network camera installed at home or the like from the mobile terminal 4 such as a mobile phone, and the dynamic DNS service can be used without requiring knowledge about the network. .

  Note that according to the above-described embodiment of the present invention, only the network camera is illustrated as the network device 1, but the present invention can be similarly applied to network storage or network home appliances. Moreover, although the portable terminal 4 was illustrated as an external connection device, it can be replaced by a mobile phone, a PC, or the like having a network connection environment. Further, according to the embodiment of the present invention, the system configuration in which the same server (dynamic DNS service server 3) provides a dynamic DNS service and a service for distributing video and audio shot and recorded by a network camera has been exemplified. The services may be received by servers that exist independently of each other.
