  • Publication number: 20240137511
    Abstract: Disclosed herein are a video decoding method and apparatus and a video encoding method and apparatus. In video encoding and decoding, multiple partition blocks are generated by splitting a target block. A prediction mode is derived for at least a part of the multiple partition blocks, among the multiple partition blocks, and prediction is performed on the multiple partition blocks based on the derived prediction mode. When prediction is performed on the partition blocks, information related to the target block may be used, and information related to an additional partition block, which is predicted prior to the partition block, may be used.

  • Patent number: 10053571
    Abstract: The present invention provides a polymer emulsion having heat sealability for a blister package, and a method for preparing the same. Since the polymer emulsion of the present invention includes latex particles having an average particle diameter of a nanosize and a low unimodal particle size distribution, it may exhibit uniform and stable emulsion properties, particularly excellent heat sealability, and thus may be suitably used for a blister package and on the like. Furthermore, the polymer emulsion of the present invention is polymerized in an aqueous medium without using an organic solvent, and thus enables provision of a blister package with minimized harmfulness to a human body and the environment.
