摘　　要：JPEG2000作为21世纪最新的静态图像压缩标准, 成为当前众多学者研究的热门课题之一。针对JPEG2000 的嵌入式应用, 采用双DSP构架, 并结合视频采集模块和以太网接口电路, 实现了JPEG2000网络平台。在介绍了网络平台的硬件组成、工作原理后,着重研究了视频采集、图像压缩和网络传输等几个关键技术。实验证明, 该网络平台接口方便、性价比高、通用性强, 为JPEG2000应用的进一步研究, 打下了坚实基础。As the new static image compression standard in 21st century, JPEG2000 becomes one of the hot tasks. According to the embedded a pplications of JPEG2000, a network platform is presented based on double DSP architecture in combination with capturing module and Ethernet interface. After the structure and the principal of hardware are introduced, several key techniques are researched. The experiment result shows that the platform is featured in convenient interface, high performance to price ratio and great generality, and sets up a solid foundation for further studies.
