An FGS(Fine Granular Scalability) coding/decoding method and a device thereof are provided to first compress a macro block having a high degree of importance, thereby remarkably improving FGS compression efficiency. Important factors and priorities of the important factors are set(S301). Information on important factors about macro blocks of a frame is extracted(S302). An important macro block map is generated by determining order of importance degrees for each macro block according to the extracted important factor information and the set priorities(S303). An FGS-based coding process is carried out in order of the importance degrees of the macro blocks of the frame by using the important macro block map(S304). |
