CODED VIDEO IMAGE DECODING DEVICE, MULTIPLEXED MEDIA REPRODUCING DEVICE, AND MULTIMEDIA INFORMATION REPRODUCING DEVICE

摘要

PROBLEM TO BE SOLVED: To improve the image quality by subjecting signals obtained by decoding the encoded video images to a proper filter.

SOLUTION: Encoded information 307 as information indicating the encoding characteristics of the encoded video images is acquired from a video image decoding processor 301, spatial distribution characteristic map information 308 as information related to the spatial distribution of encoded information for each frame is generated by a spatial distribution characteristic map information generating unit 302, and a spatial encoded strategic information 309 as information indicating a strategy when video images are encoded is computed by a spatial encoded strategic information calculating unit 303. The region, type, and intensity of a filter are determined on the basis of this information through a filter strategy determining unit 304, and the decoded video signals are filtered through a filtering unit 305.
