Abstract
Official abstract text for this publication.
The image decoding method includes: determining a context for use in a current block to be processed, from among a plurality of contexts; and performing arithmetic decoding on a bit sequence corresponding to the current block, using the determined context, wherein in the determining: the context is determined under a condition that control parameters of neighboring blocks of the current block are used, when the signal type is a first type, the neighboring blocks being a left block and an upper block of the current block; and the context is determined under a condition that the control parameter of the upper block is not used, when the signal type is a second type, and the second type is one of “ref_idx_l0” and “ref_idx_l1”.
First claim
Opening claim text (preview).
The invention claimed is: 1. A decoding method for decoding a control parameter for controlling decoding of an image, the decoding method comprising: determining a context for a current block in the image, from among a plurality of contexts; and performing arithmetic decoding on a bitstream corresponding to the current block, using the determined context to obtain the control parameter for the current block, wherein the determining further includes: determining a signal type…
