DECODING APPARATUS AND DECODING METHOD, AND CODING APPARATUS AND CODING METHOD

摘要

The present disclosure relates to a decoding apparatus and a decoding method and a coding apparatus and a coding method capable of adjusting a compression rate of a lowest limit. A decoding unit decodes a bit stream coded according to an H.265/HEVC standard having a profile in which a lowest compression rate at the time of coding an image is set for each of a main tier and a high tier in units of Coding Units (CU) that are recursively divided. The present disclosure, for example, can be applied to a decoding apparatus of an High Efficiency Video Coding (HEVC) system and the like.
