Abstract
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.
Claims10
A decoding apparatus comprising:
- a decoding unit configured to decode a bit stream coded according to a coding standard having a profile in which a lowest compression rate is set for a main tier and a high tier,
- wherein the lowest compression rate of the high tier of a level that is a predetermined level or higher and the lowest compression rate of the main tier are different from each other.
A decoding method using a decoding apparatus, the decoding method comprising:
- decoding a bit stream coded according to a coding standard having a profile in which a lowest compression rate is set for a main tier and a high tier,
- wherein the lowest compression rate of the high tier of a level that is a predetermined level or higher and the lowest compression rate of the main tier are different from each other.
A coding apparatus comprising:
- a coding unit configured to code an image according to a coding standard having a profile in which a lowest compression rate is set for a main tier and a high tier,
- wherein the lowest compression rate of the high tier of a level that is a predetermined level or higher and the lowest compression rate of the main tier are different from each other.
A coding method using a coding apparatus, the coding method comprising:
- coding an image according to a coding standard having a profile in which a lowest compression rate is set for a main tier and a high tier,
- wherein the lowest compression rate of the high tier of a level that is a predetermined level or higher and the lowest compression rate of the main tier are different from each other.
