VIDEO ENCODING

A video encoding apparatus comprising:an acquisition module (110) configured to acquire available blocks having motion vectors from encoded blocks adjacent to a to-be-encoded block and the number of the available blocks;a selection module (110) configured to select one block from the available blocks;a selection information encoding module (112) configured to select a code table from a plurality of code tables depending on the number of the available blocks, and to encode selection information specifying the selected block from the available blocks using the selected code table, the selected code table including the same number of indexes as the number of the available blocks and code words corresponding to the indexes; andan image encoding module configured to encode the to-be-encoded block by using a motion vector of the selected block.
