摘要
The present invention relates to a decoding process and spatial scalable coding method was used to derive the encoded information. In particular, when the ratio between the dimensions of the low-resolution image and high-resolution is a multiple of 3/2, and to encode the high resolution image from coding information to be used for encoding the low resolution image from relates to a method for deriving coding information to be used. Based on the macroblock class MBi, and on the basis of the position of the 8 × 8 blocks MBi_pred in the method, 8 × of each predicted macroblock MBi_pred the macroblock coding mode of the base layer macroblock is associated Each macro step 10 to derive a block coding mode for 8 blocks, the motion information of the base layer macroblock and the associated step 11, draw a macroblock coding mode for MBi_pred from the coding mode of the base layer macroblock is associated I include a step 12 to derive the motion information for the block MBi_pred.
