Design And Investigation Of A Real-Time Multimedia Transmission System Based On Embedded Linux System

With the rapidly development of multimedia signal compression and broadband networks technologies, methods of transmitting high-quality multimedia information via networks have become one hottest point of IT technologies. Researches and developments of Embedded Linux system technology are becoming another important IT technology. In this thesis, we present a real-time multimedia transmission system based on embedded Linux technology. There are three parts in the system, a pair of MPEG-2 standard codec, a transmitting system and a receiving system. We describe the whole system skeleton and principle and the design of each parts in detail. During the system design, we take advantages of these technologies, such as MPEG-2, TCP/IP, RTP and embedded Linux technology. These technologies are discussed in different chapters. To design and research a real-time multimedia transmission system based on embedded Linux not only combines multimedia signal compression technology and networks technology, but also explores the application of the embedded Linux technology. The content of this thesis might be helpful to develop the multimedia transmission technology.
