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： 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 motion estimation device configured to estimate motion for blocks included in an input picture using a reference picture includes an internal reference memory configured to store the reference picture transferred from outside the motion estimation device; a motion estimator configured to estimate motion information for a target block that is a block of the input picture and where motion is to be estimated, using pixel data of the reference picture stored in the internal reference memory; a motion compensator configured to perform motion compensation for the target block using the motion information estimated by the motion estimator; and a reference memory manager configured to control the internal reference memory. The reference memory manager is configured to control the internal reference memory to store a luminance reference picture and a color-difference reference picture as the reference picture.

摘要： A variable-length decoding device includes a data determination unit which determines whether or not each of component values decoded by a variable-length decoding unit is a specific value; a data buffer that holds only a component value which is not the specific value; a last valid data determination unit which determines component values other than the last one of the component values not the specific value in a block; a flag buffer which holds flags each having a corresponding component value among the component values from the component value at the beginning of the block to the last component value and indicating whether or not the corresponding component value is the specific value; a flag buffer control unit which sets the flags; a data buffer control unit which controls writing in the data buffer; and a selecting unit which selects either zero or a coefficient read from the data buffer.
