How to derive from the low resolution picture coding information of high-resolution pictures, and decoding apparatus and coding to achieve its way

摘要

The present invention relates to a decoding processing and spatial scalable coding using a method for deriving coding information. In particular, the invention relates to a method for deriving coding information for high resolution pictures from the coding information of low resolution picture. The step of deriving a macroblock class from the parameter (110), the above is calculated for the base layer macroblock mainly corresponding geometrical parameters characterizing the position of the higher layer macroblock (120), the method geometry dividing and dividing each higher layer macroblock macroblock of the base layer based on the HL MB class and parameters, from the corresponding sub-partition or, in some cases, the step of deriving a sub-division (20), the corresponding I and a (30) a process to derive motion information of higher-layer macro block from the motion information of the base layer macroblock.
