    • The invention relates to a method for determining for a high layer macroblock that uses inter-layer prediction a partitioning of the macroblock in partitions. It comprises the following steps: - dividing the high layer macroblock in non-overlapping high layer blocks of a predefined size; - determining a corresponding base layer pixel for one pixel, called reference pixel, of each high layer block; - identifying, for each reference pixel, a base layer macroblock to which the corresponding base layer pixel belongs, a base layer partition to which the corresponding base layer pixel belongs in the identified base layer macroblock, a base layer sub-partition to which the corresponding base layer pixel belongs in the identified base layer partition if the sub-partition exists; - deriving, for each of the high layer block, a single value, called PartInfo value; and - determining a partitioning of the high layer macroblock in macroblock partitions by comparing between them the PartInfo values associated with each of the high layer blocks.
    • 本发明涉及一种用于确定高层宏块的方法,该高层宏块使用层间预测来分割宏块中的分区。 它包括以下步骤: - 在预定义大小的非重叠高层块中划分高层宏块; - 确定每个高层块的一个像素(称为参考像素)的相应基本层像素; - 对于每个参考像素,识别对应的基本层像素所属的基本层宏块,相应的基本层像素属于所识别的基本宏块中的基本层分区,对应的基本层子分区 如果子分区存在,则基层像素属于所识别的基层分区; - 为每个高层块导出一个称为PartInfo值的单个值; 以及 - 通过在它们之间比较与每个所述高层块相关联的PartInfo值来确定宏块分区中的高层宏块的划分。
