Dual Video Wireless Transmission System Based On S3C6410

As the rapid development of the multimedia technology and network transmission technology, real-time video transmission is increasingly used in industrial monitoring, environment monitoring, security monitoring and other fields. In complex environments, such as mines and remote areas, there are issues such as wiring problems in the traditional wired video system. It is hard to build the wired video system flexibility and quickly in situations, which need to transmit video temporarily. Therefore, it is necessary to develop a flexible wireless video transmission system.In this paper, a dual video wireless transmission system is designed and implemented. With H.264 video codec technology, it is effective to reduce the demand for network bandwidth in the premise of ensuring video quality. With Ad-Hoc networks, it can build a flexible video transmission system and reduce system integration costs.Based on analyzing the characteristics of wireless video transmission system, summarizing the research status, advantages and disadvantages of current video transmission system and the design requirements of the wireless video transmission system, the general framework of the system is designed. With S3C6410 based hardware platform as the main control module, USB camera as video capture module and wireless network card as wireless transmission module, the hardware of system nodes is designed to meet the requirements of H.264 video codec and system functions. For the different functional requirements of acquisition nodes, repeater nodes and receiving nodes, the corresponding application layer program is developed after completing the design of bottom software. Through the above development of software and hardware, the various functions of three types of nodes are achieved, and the dual video wireless transmission system is also achieved. Verified by experiments, the system can excellently achieve the dual video transmission functions.
