Study On Video Transmitting System Based On ARM9

Embedded system is a special computer system, which hardware and software can be configured to reduce function, reliability, cost, size, power consumption are strictly bound, application-centric,based on computer technology. It combines the advanced computer technology, semiconductor technology, electronics technology, as well as various industry specific applications, be viewed as technology-intensive, innovative integrated system of knowledge. Consisting of hardware and software in recent years to the salient features to consumer electronics-oriented smart device to more than people think the speed of access to an unprecedented development. Embedded Linux is an open, that can be trimmed, and 32-bit real-time operating system. Compared against Windows and other desktop operating system, it has good reliability, real-time high, small size and the characteristics of the kernel, it is widely used embedded intelligent devices, industrial control, information appliances, mobile communications, personal consumer electronics and other fields, is the most widely used, the fastest-growing embedded operating system today.Summary of video capture is widely used in security transmission, video conferencing, video telephony, high-definition television, video on demand, video retrieval, digital libraries, telemedicine, and video surveillance. With the Internet growing in popularity around the world, as well as the rapid development of mobile communications, image / video coding from the research-oriented storage to transmission, at present, image / video coding technology has become one hot spot of the information science and technology research.Subject to the application of embedded systems background in research and analysis of existing embedded systems, based on research in the embedded Linux environment cutting and transplantation, as well as the operating system environment for embedded Linux device driver development methods, ARM9 S3C2410 processor in the embedded systems platform development and transfer of video transmission systems, in-depth study of the ARM platform video capture, encoding and video streaming technology, based on video encoding and TCP / IP network Video streaming has been a certain degree of understanding.
