For low-delay applications in Scalable Video Coding, there are two alternative coding strategies based on AR-FGS for
compressing multiple FGS layers. However, their coding efficiencies both suffer largely from the inherent drifting errors.
In this paper, a more efficient multiple FGS layers coding structure is presented, which can provide higher coding
performance within wide bitrate range and stronger error resilience. This is achieved by incorporating the partial-reconstructed
enhancement layer references, instead of the complete-reconstructed ones, into the motion-compensated
prediction loop of the FGS layers. Thereupon the prediction drift can be effectively decreased, especially for the middle
bitrate points. Further, through selecting different-quality enhancement layer references generated with cycle-based
reconstruction mechanism, more flexible video quality can be supported to be more suitable for varied practical
