Bluetooth Video Transmission System Based On Arm9&linux

In this paper, based on ARM9 and LINUX Bluetooth video transmission system. V4l2 focused on the S3C2440 developed under the camera interface, video-driven UART interface on the preparation and embedded Bluetooth modules.This paper sets out the background of system design and issues of mission, on the Bluetooth technology and the ARM embedded system are introduced; then analyzes the system's overall hardware design ideas and specific software development process and the overall design process, on the ZT130G2 video module, Bluecore2- External Bluetooth module and S3C2440 chip and the specific development board systems are introduced. Then describes the different modules of the circuit interface design, and different modules of workflow analysis. Next, specific description of the ARM in the embedded system development platform for building, ZT130G2 video acquisition module interface and the drive to achieve, Bluetooth module interface and module drive to achieve, focusing on the design V4L2 framework of the CAMERA-based S3C2440 video driver interface to the preparation and Bluetooth module embedded programming, especially in video-driven format added to the compression function, and finally, the actual performance of the overall system was evaluated, and a follow-up for the shortcomings of optimization.The research project, with emphasis on non-generic video driver chip interface and chip interfaces Bluetooth module, in order to study later on in the system integration and design of chip-level basis.This system can be used for security monitoring, emergency communications, short-range wireless communication environments.
