Abstract: Disclosed herein are a method and apparatus for deriving motion prediction information and performing encoding and/or decoding on a video using the derived motion prediction information. Each of an encoding apparatus and a decoding apparatus generates a list for inter prediction of a target block. In the generation of the list, whether motion information of a candidate block is to be added to a list is determined based on information about the target block and the motion information. When the motion information passes a motion prediction boundary check, the motion information is added to the list. By means of the motion prediction boundary check, available motion information for prediction of the target block is selectively added to the list.

Abstract: This invention relates to an electrolyte solution for a redox flow battery containing an organic active material, in which an organic compound useful as a single active material for a cathode and an anode is dissolved in a water-soluble solvent, and to a redox flow battery using the same. The electrolyte solution of the invention is an aqueous electrolyte solution obtained by dissolving an active material in an aqueous solvent, and is thus very stable due to the low risk of fire or explosion. Furthermore, the organic compound is applied as a single active material to the cathode and the anode, and thus, when the capacity of the battery is decreased due to the permeation of the active material through the separator, the battery capacity can be restored through rebalancing.
