什麼是嵌入式系統呢？它就是為了達成或解決某種目的而量身打造的系統。此系
統裡有顆處理器，處理且控制整個系統的行為；有個記憶體，容量不大但卻足夠它現
階段使用。
目前在我們週遭到處都可看到嵌入式系統的例子，它方便了人們的日常生活。而
目前與網路的結合更是趨勢。網路的出現讓人們可以方便的存取遠方的資料，與網路
的結合將大大的增加嵌入式系統的應用層面。
有鑑於此，本論文提出一種嵌入式網路監視系統的實現。讓遠方的使用者可以透
過網路觀看監視畫面且同時可以多位使用者上網觀看。在家庭安全，學校安全，或工
廠安方面皆有其應用的價值。
本論文使用的硬體是德州儀器公司生產的OMAP 5912 發展板。將搭配使用
LINUX來實現整個系統。

In today's world electronics appliances, the embedded systems are everywhere to solve
many system integration problems. An embedded system is a specific purpose system in
which the CPU is completely encapsulated by the device. Combining with Internet, the
embedded systems have expanded into more and more applications. Because of the
Internet, people can get the information from the remote site conveniently. This is also
one of the best advantages of the Internet. Now many applications via the Internet have
been implemented in order to facilitate modern e-life in the world.
In this research, a networking monitor system called the embedded networking
monitor system is proposed and realized without involving the computers. Once both
ends are connecting with Internet, the one to watch the dynamic images to the other end
can become possible. Of course, the topics about building an embedded Linux system
will also be illustrated.
