| Abstract: | The video monitoring system is an important assistant device in our life. A network embedded video monitoring system based on the stream media technology is presented and developed. The system is designed of the embedded processor, the DSP processor and embedded Linux operating system. The video compression part of the system is based on the MPEG4 algorithm via the DSP processor, while multicasting the real time video stream to the network based on the stream media technology via embedded processor. The system design, hardware design, software design, and the practical operating results are discussed in detail. |
