Abstract: An encoding and decoding apparatus is provided for performing arithmetic encoding and arithmetic decoding. The encoding apparatus encodes in a first bitstream first last position information, indicating a horizontal position and a vertical position of a last non-zero coefficient in a predetermined order from among a plurality of coefficients within a first current block to be encoded in a first picture. The decoding apparatus decodes second last position information, indicating a horizontal position and a vertical position of a last non-zero coefficient in a predetermined order from among a plurality of coefficients within a second current block to be decoded in a second picture.

Abstract: A decoding method of decoding encoded data per unit from among units included in a picture is provided. The decoding method decodes a first flag which indicates whether a removal time of the encoded data from a buffer is set per unit. The buffer is for storing the encoded data. The image decoding method further decodes a second flag indicating whether an interval between removal times of the units is constant when the removal time is set per unit. The image decoding method removes the encoded data from the buffer per unit and at an interval according to the second flag, and decodes the removed encoded data.

Abstract: An image coding method includes: deriving a candidate for a motion vector predictor from a co-located motion vector; adding the candidate to a list; selecting the motion vector predictor from the list; and coding a current block and coding a current motion vector, wherein the deriving includes: deriving the candidate by a first derivation scheme in the case of determining that each of a current reference picture and a co-located reference picture is a long-term reference picture; and deriving the candidate by a second derivation scheme in the case of determining that each of the current reference picture and the co-located reference picture is a short-term reference picture.

Abstract: A moving picture coding apparatus includes an intra-inter prediction unit which calculates a second motion vector by performing a scaling process on a first motion vector of a temporally neighboring corresponding block, when selectively adding, to a list, a motion vector of each of one or more corresponding blocks each of which is either a block included in a current picture to be coded and spatially neighboring a current block to be coded or a block included in a picture other than the current picture and temporally neighboring the current block, determines whether the second motion vector has a magnitude that is within a predetermined magnitude or not within the predetermined magnitude, and adds the second motion vector to the list when the intra-inter prediction unit determines that the second motion vector has a magnitude that is within the predetermined magnitude range.
