GOP-based MPEG-4 FGS bit plane R-D model is analysed and a constant quality GOP bandwidth allocation scheme for MPEG-4 FGS streams is presented. Offline and online GOP bandwidth allocation algorithms are brought forward.

• 分析MPEG-4FGS的位平面R-D模型；提出一种基于场景的常质量GOP带宽分配机制及GOP带宽分配的静态算法和动态算法；以保证同一场景内连续GOP的质量稳定.
