MPEG4 is a video coding technology with the characters of high compression ratio, low requirement for transmission bandwidth and high quality of image.
MPEG4是一种压缩率高、对传输带宽要求低、图像质量高的图象编码技术。
Therefore, it is an inevitable choice for the image data to adapt coding compression technology for processing to reduce transmission information.
因此，对图像数据采用编码压缩技术处理，减少传输的信息量成为图像快速传输的必然选择。
The Method based on the DCT transformation has been the center technology for most of the digital image and video coding standards, since it features on good de-correlation and energy compression.
基于分块dct变换的编码方法，由于具有良好的去相关性和能量压缩特性，已经成为现有大多数图像和视频编码标准的核心技术。
