摘要
为了解决传统模拟视频系统带宽太宽、易受干扰的问题,设计了一种满足无线信道传输视频信号的特殊要求的视频压缩子系统。该系统的算法采用基于小波变换的M-JPEG2000算法,没有帧间压缩,非常适合在实时性要求很高的情况下压缩数字视频,并且没有JPEG的方块效应,且具有很强的灵活性,可根据不同的需要来通过软件配置来满足其要求。
A video compression sub - system is designed which can meet the special demand of video signal transmission through wireless channel, need no broader bandwidth, and is not vulnerable to noise. The sub system adopting M - JPEG2000 based on wavelet transform is suitable for the situation requiring real time images because it does not utilize the correlation among frames of the video images and there is no block effect of JPEG. Through software configuration, differentrequirements can be met.
