Abstract: A video decoding apparatus decodes a sequence of one or more pictures in the unit of blocks which are split from each picture. The apparatus comprising a decoder configured to reconstruct, from a bitstream, a current motion vector difference of the current block among the blocks which belong to the sequence of one or more pictures, and an image decoder configured to predict and decode the current block using the motion vector of the current block. When the current motion vector difference of the current block is zero, the resolution of the current motion vector difference of the current block is set to the ¼ pixel precision without the information on the motion vector resolution extracted.

Abstract: A method of manufacturing a hydrophilic membrane and hydrophilic membranes having improved antifouling property using a supercritical fluid or a subcritical fluid. The method involves combining a coating solution from a hydrophilic group-containing monomer, an initiator, a cross-linking agent and a supercritical fluid or subcritical fluid in a high pressure solution vessel and transferring the coating solution to a membrane in a high pressure coating vessel, coating the surfaces and micropores of the membranes through cross-linking polymerization reactions. Non-reacted coating material is returned to the high pressure solution vessel. The membranes are removed from the coating vessel, cleaned and dried. The hydrophilic membrane manufactured by the present invention is excellent in properties of hydrophobic membranes such as thermal stability, chemical stability and mechanical strength, and surfaces and micropores of the membranes are uniformly coated.
