Abstract


With the development of mobile Internet to the direction of multimedia information applications plus mobile terminal processing chip toward the development of efficient, low power consumption, small size, direction, and also more functional requirements of multimedia services on the mobile platform. Interact through live video and audio in the accident in the handling of public places, the relevant departments to a more comprehensive understanding of the situation of emergency incidents more quickly respond to emergencies, adequate coordination of relevant personnel. Phone mobile monitoring system to monitor the video signal through the mobile Internet transmission, so as to achieve the purpose of the real-time monitoring of the scene. Of actual work needs to the university campus for the test sites, a more in-depth study of the key technologies of image compression, wireless network transmission, final design and development of a set of mobile video collection and transmission system. The main work of this paper is as follows: 1, to study and achieve universal audio and video codec framework: the rapid development of audio and video codec technology, such as the new one codec technology, existing products will not be able to use. Based on the current situation, the analysis and research a variety of audio and video codec technology, to extract its versatility, plug-in technology to realize the framework platform; 2, adaptive video transmission protocol: Because the system is based on wireless network transmission wireless network there are many ways unreliable factors. The need to achieve perfect agreement with the analysis of real-time network conditions, optimize the use of network resources to achieve. On the one hand through the RTCP feedback report real-time analysis of network conditions, In addition, the system also adds real-time detection of network monitoring module on the network. Comprehensive maybe results hierarchical network conditions, and then, depending on the network conditions corresponding strategy, sampling through dynamic change video frame rate and resolution size, so as to achieve the optimal use of the network performance. 3 video capture system based on the mobile platform was designed and implemented, the system includes client and server side. The client program includes video capture, encoding, transmitting a series of functions, the server-side application development using the Windows Server development technologies (IOCP) network data reception, data decoding output, and data storage functions. In addition, the client also increase the basic functions such as login, logout; another server-side program is also designed for multi-client management and maintenance, and management of video files and maintenance. Finally, given the final operation of the system and operating results more fully reflect the performance of the system and the role of objective reflects the system's functionality and advantages and disadvantages.
