討論了基于MPEG-4的嵌入式網(wǎng)絡(luò)視頻服務(wù)器的設(shè)計方案，包括圖像壓縮、存儲方式、通信和操作系統(tǒng)。這4個系統(tǒng)分別實現(xiàn)視頻節(jié)目的壓縮、大容量視頻存儲、快速的傳輸通道和節(jié)目檢索與服務(wù)等功能。由于人們對VOD不斷提出新的要求，所以提出了在設(shè)計時應(yīng)該注意的問題。

Abstract：This article discusses a design of an embedded video server system based on MPEG-4, including the image compress，storage architecture，communication system and operation system . One system is used to compress images, and one of the four system is used to memory. The system also provides a straight channel to transmit information. We can recall the broadcasted programs. People put forward some new requests for VOD, so we present some items which should be noticed.
Keywords: video server，embedded，MPEG-4, storage architecture
