Abstract: Disclosed herein are a video decoding method and apparatus and a video encoding method and apparatus. Coding decision information of a representative channel of a target block is shared as coding decision information of a target channel of the target block, and decoding of the target block is performed using the coding decision information of the target channel. Since the coding decision information of the representative channel is shared with an additional channel, repeated signaling of identical coding decision information may be prevented. By means of this prevention, the efficiency of encoding and decoding of the target block or the like may be improved.

Abstract: Provided is an aerogel blanket and a method for producing the same, wherein a catalyzed sol is sufficiently and uniformly impregnated into a blanket in an impregnation tank, and the catalyzed sol is allowed to stay in the impregnation tank for a specific time to control fluidity while achieving a viscosity at which the catalyzed sol can be easily introduced into the blanket, thereby forming a uniform aerogel in the blanket. As a result, the uniformity of pore structure and thermal insulation performance of an aerogel blanket are improved, the loss of raw materials is reduced through the impregnation process, the occurrence of process problems is reduced, and the generation of dust is reduced.

As a result, the uniformity of pore structure and thermal insulation performance of an aerogel blanket are improved, the loss of raw materials is reduced through the impregnation process, the occurrence of process problems is reduced, and the generation of dust is reduced.
