摘要： An image encoding and decoding method comprises the steps of: determining an inter-component prediction mode of a chrominance component block on the basis of an inter-component prediction mode list and predetermined index information; determining a reference sample for inter-component prediction of the chrominance component block on the basis of the determined inter-component prediction mode; deriving the parameters of a linear prediction model by using the reference sample; and performing inter-component prediction for the chrominance component block by using the parameters of the linear prediction model.

摘要： A smoking jig using a pot-type heating method is provided. After smoking by putting tobacco leaves into the smoking jig, a user may remove tobacco leaves remaining after finishing smoking and put the tobacco leaves to an ashtray by performing an operation called “Shag-Pon.” However, in the case of a smoking jig using a pin-type heating method, a user cannot discard the tobacco leaves remaining after finishing smoking to an ashtray after smoking by putting tobacco leaves into the smoking jig. Accordingly, a notch is formed at a part of a tobacco leaf insertion tube so that pellet-shaped tobacco leaves are placed into the notch. As a result, a user may pull both a mouthpiece and the tobacco leaf insertion tube out of the smoking jig and remove the tobacco leaves remaining after finishing smoking from the notch and put the tobacco leaves to an ashtray.

摘要： A method of decoding a video signal according to the present invention may include: determining whether or not change in brightness is present between a current video including a current block and a reference video of the current video; when it is determined that change in brightness is present between the current video and the reference video, determining weight prediction parameter candidates of the current block; determining a weight prediction parameter of the current block on the basis of index information specifying any of the weight prediction parameter candidates; and performing prediction for the current block on the basis of the weight prediction parameter.

摘要： The present invention relates to a block partitioning structure from among the video coding schemes, and a method and apparatus for encoding and decoding the block partitioning structure. The video encoding and decoding method comprises the steps of: combining two or more encoding units of maximum size into a single encoding unit group; acquiring encoding data corresponding to the combined single encoding unit group; and decoding, according to a decoding order, the two or more encoding units of maximum size contained in the single encoding unit group.
