Abstract: Provided are methods and apparatuses for encoding and decoding a multiview video. The method of decoding the multiview video includes obtaining a data unit including encoding information of texture pictures and depth map pictures of a multiview image related to a same point of time, obtaining, from the data unit, view information of pictures that are encoded and are included in the data unit, type information indicating a type of each of the pictures from among the texture pictures and the depth map pictures, and reference flag information indicating whether each of the pictures is previously inter-layer predicted by referring to a texture picture of the same point of time or to a depth map picture of the same point of time, determining an encoding order of the pictures, based on the obtained information, and decoding the texture pictures and depth map pictures based on the determined encoding order.

Abstract: Provided are entropy encoding and entropy decoding for video encoding and decoding. The video entropy decoding method includes: determining a bin string and a bin index for a maximum coding unit that is obtained from a bitstream; determining a value of a syntax element by comparing the determined bin string with bin strings that is assignable to the syntax element in the bin index; storing context variables for the maximum coding unit when the syntax element is a last syntax element in the maximum coding unit, a dependent slice segment is includable in a picture in which the maximum coding unit is included, and the maximum coding unit is a last maximum coding unit in a slice segment; and restoring symbols of the maximum coding unit by using the determined value of the syntax element.
