Panoramic Video Sessions Model And System Study Under Wireless Networks

Nowadays, the multimedia applications to be the integral part of the modern business life, the efficient use of streaming media and frequency of operational have become a symbol of the business community. Meanwhile, with the ability of the computing device enhancing and the rapid development of low-bandwidth networks, video conversation gradually led to the services into the inevitable combination. In recent years the development of wireless communication technologies has become a major national telecommunications and information technology applications, also, the multimedia services in the traditional integration of resources are more important than before.This paper is based on the wireless networks, focusing on the low-bandwidth wireless network performance, which study for media streaming planning and analysis, focusing on the key part of the system hardware and software principles. The optimum design will eventually solve the potential problems. Also,the author propose the theories which based on streaming media codec, embedded multi-thread multi-process operating system of scheduling and design of communication, network communication protocol algorithm and its modular design can be product-oriented and modularization for improving streaming media services and optimization data transform processing algorithm.The main works and innovations are as follows:According to the features and requirements such as streaming media video chart system, fisheye-based panoramic video coding and decoding processing, wireless networks, the author dip into the wireless panoramic video conversation systems and products which include communications protocol optimization and wireless networks exception handling researching and design. Rely on the multi-environment construction and modular design concept to create the source filter under DirectShow structures.For the variety of different types of streaming media formats, we speed up the data access and alternation by flow control with handle source and transform filter streaming media data processing under DirectShow structures. The author proposed the self-defined algorithms and network communications control protocol which improves the software implementation and follow-up of panoramic real-time video session which provides real-time video and extension platform for benchmark. The distinguishing features of this paper are as follows: the panoramic video for wireless network model session, focusing on the low-bandwidth wireless networks programming and resource scheduling optimization algorithm analysis. Achieving a wireless streaming media data with the network conditions change dynamically.The client could run stably under Microsoft Windows XP Professional (SP2), Windows 2000, Windows 2003, Windows ME, Windows Vista and Windows 7 OS that equips with DirectX9.0. The server could run stably under Linux 2.6.x OS. The demo show that the design could make targets up to panoramic vision, achieve real-time streaming audio and video synchronized media experience. The simulation system uses 802.11g protocol (20 meters barrier-free environment) that could fulfill the failure and error rate of the proposed method of on-demand audio and video data less than 0.03% that takes 20,000 times experiment connection. The author speed up the streaming media data transform and improve processing capability, with ensuring anti-jamming performance of wireless data capacity.
