Method of transmitting real-time network image
First Claim
1. A method of transmitting a real-time network image, applied to a network system comprising an IP camera, a NAT router, the Internet, and a server of an Internet service provider (ISP), wherein the NAT router and the ISP server are linked to the Internet, respectively, while the NAT router is provided with a DHCP server;
- when the IP camera is linked to the Internet via the NAT router, the IP camera executing the method comprising steps of;
searching the DHCP server in the NAT router according to a DHCP protocol, and sending a request for an IP address;
linking to the Internet according to the received IP address;
linking to the ISP server via the Internet according to the received IP address, and registering the IP address and a predetermined identification (ID) code of the IP camera to the ISP server; and
starting to capture a real-time image, and transmitting the captured real-time image to other remote electronic device through a linking channel built-up between the IP camera and the ISP server via the ISP server after determining that the ISP server sends back a registered response and receiving a request for transmitting the real-time image from the ISP server.

Abstract
A method of transmitting a real-time network image is applied to a network system having an IP camera, a NAT router, the Internet, and a server of an Internet service provider (ISP). The method includes steps of: requesting an IP address from the DHCP server by the IP camera according to a DHCP protocol when the IP camera is linked to the Internet via the NAT router; automatically logging the IP camera in the ISP server after requesting the IP address and linking to the Internet; and building up a linking channel between the IP camera and the ISP server after finishing logging. As a result, other remote electronic devices can download a real-time image captured by the IP camera through the linking channel via the Internet after logging in the ISP server.
