| 摘 要： | 为了满足视频传输的高实时性和无线信道的窄信道要求,设计了一种基于JPEG2000的视频压缩及解压缩系统。通过专用芯片ADV202实现JPEG2000压缩方式,其优点是在窄信道下具有高实时性。使用FPGA实现跳像素并通过配置ADV202寄存器实现跳场减少数据,满足了窄信道下实现较低压缩率压缩视频图像的要求,提高了视频图像还原质量。

| Abstract: | A video compression and decompression system based on JPEG2000 compression standard is designed to meet the demands of high real -time and narrow wireless channel. JPEG2000 compression is achieved by the specific chip ADV202 in this system and it has such characteristic as high real-time in the narrow channel. By using FPGA to skip pixels and by configuring ADV202 to skip fields, the system can adopt a low compression ratio to meet the demand of narrow channel, and improve video decompression quality. |
