摘要： A variable-length code decoding apparatus that decodes a bitstream includes: a storage unit that stores a variable-length code table; a bitstream cutout unit that outputs a bit string of a fixed length; a reference unit that outputs decoded data and a code length with reference to the storage unit; a determination unit that determines whether a bit string of the fixed length is accumulated; a determination unit that determines whether a bit string of a length that is shorter than the fixed length is accumulated; and a selection unit that selects one of the determination results from the determination units. The bitstream cutout unit sets a starting bit based on the selected determination result, and the selection unit switches the selection of the determination results from the determination units.

摘要： In a multiview video decoding device conforming to H.264/AVC, the amount of calculation in a reordering process on a reference picture list is reduced. This is achieved as follows. A view index selector extracts only an entry or entries whose view IDs correspond to an inter-view reference flag which is 1 from a view ID list which defines an association between view indices and view IDs, stores the view indices of the extracted entry or entries as search targets into a view index storing section, and searches for and selects a view index which is equal to a given variable picViewIdxLX (X is 0 or 1). A view ID selector stores the view IDs of the extracted entry or entries as a reference picture list, and selects a view ID based on an address of an entry hit in the view index storing section.

摘要： A variable length code decoding apparatus according to the present invention includes: an extracting unit which extracts a bit string from a beginning of a bit stream; a first storage unit for storing a plurality of code words in which one piece of data has been coded, and decoded data and code lengths respectively corresponding to the code words; a second storage unit for storing a plurality of code words in which two or more pieces of data have been coded, and decoded data and code lengths respectively corresponding to the code words; a first judging unit which judges whether one of the code words stored in the first storage unit is included in the extracted bit string, and, when judged as being included, outputs the decoded data and the code length of the code word; and a second judging unit which judges whether a code word stored in the second storage unit is included in the extracted bit string, and when judged as being included, outputs the decoded data and the code length of the code word, wherein the extracting unit extracts the bit string to be decoded next in the same cycle as a cycle in which the judgment was made by the first judging unit, and extracts the bit string to be decoded next in a cycle following the cycle in which the judgment was made by the second judging unit.

摘要： A multiview video decoding apparatus which sufficiently suppresses artifact in a decoded image even when an error occurs in the to-be-decoded image. It decodes a video stream including first coded video information of a first viewpoint and second coded video information of a second viewpoint, and includes: a decoding unit which decodes the video stream; and an error detecting unit which detects an error in the video stream; and an error concealing unit which conceals the error and includes (i) a decoding control unit which, when the error is in first coded image information in the first coded video information, causes said decoding unit to decode second coded image information included in the second coded video information and to be decoded after the first coded image information and (ii) a concealment processing unit which conceals the detected error, using decoded image information generated by decoding the second coded image information.
