Enhanced advanced pyramid broadcasting with scalable capability
具有可伸缩性的增强型高级锥形广播算法

Mirrored-Pyramid Broadcasting(MPB) can reduce the client buffer requirement of Pyramid Broadcasting(PB),and Enhanced Mirrored-Pyramid Broadcasting(EMPB) and Advanced Pyramid Broadcasting(APB) are the improved ones.But APB does not have the flexibility or best performance.Based on the analysis of these schemes, a new broadcasting scheme of SAPB was proposed.It can meet the various client buffer requirements,and use a scalable parameter to get the scalable capability and better performance.By adopting this scheme,VoD system will be more flexible and adaptive.
