The Technology Of The Embedded Streaming Media Terminal Based On WinCE

With the rapid development of the embedded technology, the micro-processing technology and the streaming media technology, the video on demand and the video conferencing based on the embedded system have become a hot research field. Because the characteristics of the embedded system itself, such systems usually have many advantages, such as small, low power, low-cost, reliable, portable and so on.This paper mainly studies the operating system of WinCE, the technology related to the streaming media and the streaming media terminal using the operating system of WinCE based on the platform of ARM11 processor hardware. The core of this player terminal is the ARM11 processor which has 32-bit high-performance, on this basis, using the embedded operating system of WinCE, the technology of MPEG-4 video encoding and decoding and the technology of streaming media network transmission to design.In the beginning of this article, the background of subject and the situation at home and abroad are introduced. Afterward, the key technology involved and the design of Overall system are described in detail. Then, according to system requirements, the chip is selected and reasonable determined, and the major hardware modules are described. Then the platform of Windows CE is built and Platform Builder 6.0 is used as the development environment. The application program which mainly completes network setup, web browsing, local playback, network play and infrared remote control uses C # language and DirectShow technology. After coding and debugging, it has basically achieved the desired design requirements and achieves to play the streaming media.
