The progressive fine granularity scalable (PFGS) coding is a promising technique for streaming video applications due to its much higher coding efficiency than the FGS (Fine Granularity Scalable) coding in MPEG-4 standard.

• 渐进精细可伸缩(PFGS)的视频编码是面向Internet的视频流化应用中的一项重要技术；同MPEG-4标准中的精细可伸缩(FGS)的视频编码相比；PFGS视频编码具有更高的编码效率.
