Claim Text:
1. An image processing method of generating a signal encoded at multiple different levels of quality within a hierarchy, the image processing method comprising: selecting an element from a rendition of an auxiliary map at a first level of quality in the hierarchy; subdividing the selected element in the auxiliary map at the first level of quality into multiple sub-elements of an auxiliary map at a second level of quality in the hierarchy, the second level of quality higher than the first level of quality; and based at least in part on auxiliary information assigned to at least one element in the auxiliary map at the first level of quality, generating in the auxiliary map at the second level of quality respective auxiliary information for each of the sub-elements at the second level of quality, the auxiliary information in the auxiliary map at the second level of quality for each of the sub-elements specifying motion at a higher resolution than a resolution of the sub-elements in the auxiliary map at the second level of quality.
