Abstract
The present disclosure relates to a decoding device including circuitry configured to decode a bit stream and generate a quantized value; and inversely quantize the generated quantized value by using a flat scaling list, in a case where a block size of a transform block to which a transform skip is applied is larger than a 4 by 4 block size.
Claims28
A decoding device comprising:
- circuitry configured to
- decode a bit stream and generate a quantized value;
- and
- inversely quantize the generated quantized value by using a flat scaling list, in a case where a block size of a transform block to which a transform skip is applied is larger than a 4 by 4 block size.
1 more element
A decoding method, wherein a decoding device performs, via a processor, the following steps:
- a decoding step that decodes a bit stream and generates a quantized value;
- and
- an inverse-quantization step that inversely quantizes the generated quantized value by using a flat scaling list, in a case where a block size of a transform block to which a transform skip is applied is larger than a 4 by 4 block size.
An encoding device comprising:
- circuitry configured to
- generate a quantized value by quantizing a transform block to which a transform skip is applied, by using a flat scaling list, in a case where a transform skip is applied to the transform block larger than a 4 by 4 block size;
- and
- encode the generated quantized value.
