摘　　要：在基于多媒体DSP处理器DM642并行处理平台上,提出一种雷达、电视视频图像压缩解压缩技术系统方案。采用多尺度小波分解技术和MPEG4压缩解压缩技术,分别对采样后的雷达视频、电视及红外视频数据压缩并分发到网络,由终端接收解压缩后融合实现多层多窗口综合显示。应用该方案可以实现舰载视频传感器和显控台以及武器系统的动态组合,提高装备的使用灵活性。This article presents a systematic scheme for Radar/TV video compression and decompression technique Based on parallel processing platform for multimedia DSP processor DM642, it adopts multi-dimensional wavelet decomposition technique and MPEG4 compression and decompression technique to separately compress sampled radar/TV IR video data and distribute them to the network, and then the data will be received and decompressed by the terminal for fusion to make integrated display in multiple layers and windows. The use of the scheme can accomplish dynamic combination of shipborne video sensors, consoles and weapon system, and improve the operational flexibility of equipment.
