【摘要】 为了对视频图像进行实时有效的压缩,提出了一种基于小波变换的视频实时压缩编码系统。该系统以小波变换技术为核心,首先采用ADV612实时压缩编码芯片对视频图像进行硬件压缩编码处理;然后结合高速数字信号处理器—TMS320VC5509对分辨率为760×420和帧速为25fps的视频信号进行了实时压缩编码。实验结果表明,该系统的性能指标达到512kbps～1.5Mbps的设计要求,并具有实时性高、结构简单和扩展性好等优点。更多还原

【Abstract】 The design of a real-time video compression and coding system based on wavelet is put forward for realizing the effective real-time video compression. The key technical point in this system is wavelet transform. Firstly,the device ADV612 is used for real-time hardw are video compression and coding,then DSP TMS320VC5509,video data which is 760×420 resolution and 25 frames per system meet 512 kbps~1.5 Mbps and has a number of advantages of high real-time speed,simple system structure and good extensibility.更多还原
