MPEG-4 fine-granularity-scalable (FGS) technology is an effective solution to resolve the network bandwidth varying because FGS provides very fine granular SNR scalability. However, this scalability is obtained with sacrifice of coding efficiency. An one-loop FGS structure is presented based on motion compensation (MC + FGS) to improve the coding efficiency of base FGS. Then it describes and discusses the hybrid spatial-SNR FGS (FGSS) structure that extends SNR scalability of FGS to spatial scalability (spatio-SNR scalability). FGSS structure inherent the low coding efficiency of FGS structure. Combining MC + FGS structure with FGSS structure, a structure of MC + FGSS structure is obtained which acquires both structures' advantages and counteracts both structures' defects. Experimental results prove the MC + FGSS structure not only obtains fine granular spatio-SNR scalability, but also achieves high coding efficiency.
