Design Of The Wireless Video Terminal

Along with the widespread application of the Wireless Local Area Network(WLAN), In order to integrate wireless LAN embedded systems for video transmission of broadband communication technology. This article is based on the ARM 11 hardware platform and embedded Linux operating system, the design of wireless video terminal system.Describes the system's overall design and main modules of the design and implementation, Which mainly include Minimum System,CCD analog video capture module, WLAN module hardware design, Embedded Linux driver transplantation and application implementation, etc. The system can be applied to video surveillance.In the embedded system wireless communication networks transplantation, analysis, improvement, The current embedded systems and wireless networks the latest development, Design a high-end applications for WLAN terminal platform, But can also support other peripheral interface. Paper constructs the platform hardware and software systems, Hardware system is used in Samsung's ARM11 processor. Describes the ARM 11 based hardware design, systems transplant and driver develop, The main circuit module includes hardware and software systems in two parts.Software components included the hardware platform running Linux operating system, And through cross-compiling and porting, debugging CCD analog video input and interface-based 802.11b/g wireless LAN SDIO Driver. Embedded wireless video terminal-based connection, the establishment of embedded wireless communication networks.
