    Abstract: Provided is a method of performing parallel entropy encoding and parallel entropy decoding by using a plurality of processors. The method includes: sequentially performing entropy encoding on a first row of blocks from among blocks that each have a predetermined size and are obtained by splitting and encoding an image, determining initial entropy coding probability information of a foremost block of a second row of blocks as entropy coding probability information updated by a block of a fixed position of the first row of blocks, sequentially performing entropy encoding on blocks of the second row of blocks which are serially arranged based on the initial entropy coding probability information, and after the entropy encoding is completed to a last block of the first row of blocks, initializing internal state information of an entropy encoded bit string of the first row of blocks.

    Abstract translation: 提供了通过使用多个处理器来执行并行熵编码和并行熵解码的方法。 该方法包括:从每个具有预定大小的块中顺次执行对第一行块的熵编码,并通过分割和编码图像获得,确定第二行块的最前面的块的初始熵编码概率信息为 由第一行块的固定位置的块更新的熵编码概率信息,对基于初始熵编码概率信息串行排列的第二块块的块顺序执行熵编码,并且在熵编码之后 完成到第一行块的最后一个块,初始化第一行块的熵编码比特串的内部状态信息。

    Abstract: Provided are a method and apparatus for encoding or decoding a coding unit on an outline of a picture. An image decoding method and apparatus according to an embodiment determine whether a current coding unit extends across an outline of a picture, by comparing a location of the current coding unit in the picture to at least one of a width and a height of the picture, split the current coding unit in at least one direction into a plurality of coding units based on a shape of the current coding unit upon determining that the current coding unit extends across the outline of the picture, obtain block shape information and split type information of the current coding unit from a bitstream and split the current coding unit into a plurality of coding units based on the block shape information and the split type information upon determining that the current coding unit does not extend across the outline of the picture, and decode a coding unit that is no longer split among the plurality of coding units.
