MOVING-PICTURE ENCODING/DECODING METHOD AND APPARATUS

摘要

In one embodiment, a moving-picture decoding apparatus is disclosed. A decoding unit decodes input coded data to generate a quantized transform coefficient and filter information. An inverse-transform/inverse-quantization unit executes inverse-quantization and inverse-transform on the quantized transform coefficient to generate a prediction error picture. A decoded-picture generation unit generates a decoded picture using the prediction error picture and a predicted picture. A luminance filter processing unit applies a luminance filter to the luminance signal of the decoded picture based on luminance filter information to generate the luminance signal of a restored picture. A chrominance filter processing unit applies a chrominance filter to the chrominance signal of the decoded picture based on chrominance filter information to generate the chrominance signal of the restored picture.
