Abstract:
While maintaining a high degree of freedom in choosing partition sizes and transformation sizes adapted for local characteristics of videos, the amount of metadata is decreased. A video encoding apparatus ( 10 ) divides an input video into blocks of a prescribed size and encodes the video block by block. The video encoding apparatus is provided with: a prediction parameter determining portion ( 102 ) that decides the block partition structure; a predictive image producing portion ( 103 ) that generates predictive images, partition by partition, as prescribed by the partition structure; a transform coefficient producing portion ( 107 ) which applies one of the frequency transformations included in a prescribed transformation preset to prediction residuals, i.e. the differences between predictive images and the input video; a transform restriction deriving portion ( 104 ) which generates the list of transform candidate, i.e. lists of frequency transformations that can be applied to each partition, on the basis of partition format information; and a variable-length-encoding portion ( 108 ) which, on the basis of the list of transform candidate and the transformation preset, performs variable-length encoding on transformation selection flags.

Claim (Index 1):
A video decoding apparatus that executes a decoding processing for input encoded data for each block, comprising:\n a variable-length decoding portion that decodes a partition structure from the input encoded data; a predictive image producing portion that produces a predictive image for each partition that is specified by the partition structure; and a transform candidate deriving portion that determines a set of transform candidate that is a set of applicable transforms being included in a predetermined transform preset based on a feature of partition size, wherein the feature of partition size indicates that the partition is a laterally long rectangle or a longitudinally long rectangle.
