Method for Deriving Coding Information for High Resolution Pictures from Low Resolution Pictures and Coding and Decoding Devices Implementing Said Method |
摘要 |
The invention relates to spatially scalable encoding and decoding processes using a method for deriving coding information. More particularly, it relates to a method for deriving coding information for high resolution pictures from the coding information of low resolution pictures. The method mainly comprises the following steps: Computing geometrical parameters characterizing the position of said high layer macroblock relatively to the corresponding base layer macroblocks and deriving from these parameters a macroblock class; Deriving a partition and possibly sub-partitions for each partition of said high layer macroblock from corresponding base layer macroblocks partition and sub-partitions on the basis of the geometrical parameters and HL MB class; and Deriving motion information for said high layer macroblock from motion information of corresponding base layer macroblocks.
