Description

System and method for identifying networked devices to establish point-to-point connections

The present invention relates to a system and method for establishing a point-to-point connection, and more particularly to a system and method for identifying a networked device to establish a point-to-point connection.

With the advancement of technology and the popularity of the Internet, users can set up a network camera in advance in the place to be monitored, and monitor the image of the network camera around the world via the Internet, and when an emergency occurs, the user You can also use the internet-connected alarm system to notify local response centers to take urgent steps to avoid an emergency out of control. Although the Internet has excellent value in combating crime and preservation evidence, the conventional network camera needs to be equipped with network wiring. If the security facility is to be used in a general residence, complicated network wiring must be installed. Configure your webcam in every corner of your home. In view of the above-mentioned shortcomings, the current market generally uses a wireless local area network to connect various network cameras, and since a physical network route is not required, a complicated installation process is eliminated. However, the wireless local area network is not without drawbacks, because wireless transmission uses electromagnetic waves as a medium for data transmission, and indoor electromagnetic waves are blocked by the space between the wall and the upper and lower floors, which limits the use of wireless transmission.

Power Line Communication is considered one of the most competitive technologies in the future of the Last Mile solution for broadband network access due to the lack of physical network routes and the lack of wireless local area networks. . Power line transmission, as its name suggests, refers to a communication technology that uses high-speed data, voice and video multimedia services in existing residential power lines. The technology works by transmitting signals in the 4MHz to 21MHz or 2MHz to 30MHz frequency bands. The transmitting end encodes and modulates the communication signal by using orthogonal frequency division multiplexing (OFDM) technology, and then performs data transmission on the power line, and firstly filters the modulated signal through the power line coupler and the high frequency filter at the receiving end, and After decoding and demodulation, the original communication signal can be obtained. Because there is no need to reroute the route and the signal strength is not affected by the obstacles in the indoor obstacles, it can save the high installation cost and the possibility of not receiving the signal. The patents relating to power line transmission can be found in U.S. Patent Publication No. US2005/0047379 and U.S. Patent Publication No. US2004/0186908.

Although power line transmission can make full use of power lines, for line cameras that are connected in different locations, power line transmission can be used with point-to-point to achieve the purpose of monitoring images in the home through the Internet. Please refer to a network image monitoring and device control system disclosed in the Republic of China Patent No. M382669, which includes a photographing device, a power line network bridge, a first router, a second router, and a point-to-point server. With a monitoring device. The camera captures the image and compresses the image into a digital image signal, and transmits the digital image signal to the power line network bridge, and then connects to the Internet via the first router. When the camera is connected to the Internet and automatically connected to the point-to-point server, the point-to-point server will hole punch the first router connected to the camera, and will automatically connect to the monitor when it is connected to the Internet. a point-to-point server, which will punch a hole in the second router connected to the monitoring device. After the hole punching process, the camera device can establish a direct connection with the monitoring device, that is, the camera device The image signal can be transmitted to the monitoring device without going through a point-to-point server.

Although the system proposed in the above case can connect the photographic device and the monitoring device through the power line, the point-to-point connection mechanism of the system can only be applied to the peer-to-peer server operated by the service provider or the network with the same software.

The degree increases, for example, a combination of more than 10 digits or English. When the user wants to select a network device for monitoring, the identification code (ID) corresponding to the networked device must be input in the near-end device, even if the near-end device is a smart phone, the identification code (ID) with too many digits It also causes the manual input process to be too complicated to quickly establish a connection between the near-end device and the networked device.
