| 摘要 |
The invention concerns the encoding of at least one current block (CTBu; CTB'u) of a first image component relative to a reference block of at least one second image component (Cl21), said first and second image components being representative of a same scene, said reference block having previously been subjected to encoding by partitioning, then to decoding, said partitioning of the reference block being carried out a plurality of times until a predefined level (k) (k>0) of depth of partitioning is obtained. The method of encoding according to the invention comprises the steps which consist, on the basis of the type of the first and second image components, of: - either partitioning (C33a)) the current block a plurality of times until a level of depth of partitioning (k') dependent on the level of partitioning (k) of the reference block is obtained, - or partitioning (C34b)) the current block based on a level of depth of partitioning previously initialised (C33b)) by a level of depth of partitioning (k') that depends on the level of depth of partitioning (k) of the reference block. |
