The Key Technology Research Of Remote Video Monitoring System Based On Android Platform

In recent years, with the rapid development of embedded technology, wireless communication technology and streaming media technology, based on remote video monitoring of embedded mobile devices and wireless networks has been monitoring the hot area of research. Video surveillance technology along with the development of computer, networking, storage, chip technology, from the early analog video monitoring, the mid-digital video surveillance to the current intelligent network video surveillance technology, and escalating, the structure is constantly changing, constantly improve the functionality, applications continue to develop. Intelligent video surveillance systems, networking and integration is an inevitable trend of development.In this paper, the status quo and development trend analysis of video surveillance for the deficiencies of the current video surveillance system, combined with prospects for market applications designed Android platform-based remote video surveillance applications. The program is very popular Cortex family of microprocessors, the use of the Android operating system as a front-end video capture, USB camera as a video capture device, video stream data, the MPEG-4compression, and transmission of video via streaming protocols using general PC as a monitor client, remote users can browse directly to dynamic video, monitoring the region to achieve the purpose of real-time monitoring. This paper presents the main remote video surveillance system based on the Android platform technologies, including transplantation and monitoring of the Android system software development technology, USB camera driver development technology and streaming media network transmission technology.Remote video surveillance platform based the Android CortexA8hardware and software design, custom transplant Android open operating system, using the the Vimicro ZC0301P master chip USB camera video image acquisition front-end, remote video monitoring system development platform Construction Remote video surveillance system components include:video capture module, the embedded Web video server module, based on the streaming video transmission protocol module and remote video surveillance terminal.Android operating system platform, by virtue of its good stability, portability and openness in the embedded field has broad prospects. Support the CortexA8embedded hardware platform for the Android operating system features, the first analysis of the Android system of the transplant process and attention to detail, knowledge of the system framework, application components, and multimedia software development. Then the USB camera images collected needs, detailed description of the details of the architecture of the USB drive and USB camera driver development, compile USB camera driver in the Linux code to add content, as well as based on V4L2USB camera data acquisition step. Finally elaborated based on streaming technology in remote video surveillance system, the main analysis Real-time Transport Protocol (RTP) and Real-time Transport Control Protocol (RTCP), USB camera capture MPEG-4video stream of RTP packets and use open source JRTPLIB library, a basic RTP/TCP architecture for real-time transmission of MPEG-4video streams.Based on the Android embedded video monitoring system, the integration of computer technology, embedded technology, the USB camera driver technology, image acquisition and processing, and multimedia technology, adapt to the video surveillance system digital, intelligent, network development trends in the Intelligent Home traffic regulation, safety of residents, campus monitoring, enterprise security, public safety, engineering, command and other very large value.
