| Abstract: | Network interface plays a key part in image transmitting over LAN or Internet. In this paper the network interface used for network cameras based on TCP/IP protocols is dealt with. A cheap and practical scheme of network interface is realized which adopts MAC controller and single-chip microcontroller. The hardware composition is given and the realization of the related protocols and the receiving based on Winsock API for the network camera application is discussed. The reasons and processing methods about the phenomena of the packet lost and packet out-of-order in image transmitting utilizing UDP protocols are also discussed. The experimental results are given in the end based on the LAN condition. |
