摘要:
Provided is a moving picture decoding apparatus including: a picture memory (103) that stores previously decoded picture data of a picture including macroblocks and macroblock information described on a macroblock basis, in association therebetween; an error judging unit (104) that judges presence or absence of an error for a current picture to be decoded; a picture data replacing unit (109) that replaces, when an error is present, picture data of the current picture to be decoded with that of a previously decoded picture in the picture memory (103); and a macroblock information replacing unit (113) that replaces macroblock information in association with the current picture to be decoded including an error with macroblock information stored in association with the previously decoded picture, or a macroblock information storage unit (602) that stores information that indicates presence of the error for the current picture to be decoded in association therewith.
摘要:
An image decoding device (C100) which increases decoding efficiency and can be easily implemented includes: a division unit (C101) dividing coded image data into first and second coded image data; a frame storage unit (C102); first and second decoding units (C103 and C104) decoding, in parallel, the first and second coded image data; and an information storage unit (C105). The first decoding unit (C103) decodes the first coded image data using second decoding result information stored in the information storage unit (C105) and stores, as first decoding result information, a part of information generated by the decoding into the information storage unit (C105). The second decoding unit (C104) decodes the second coded image data using the first decoding result information stored in the information storage unit (C105) and stores, as the second decoding result information, a part of information generated by the decoding into the information storage unit (C105).
