Claim:
1. A method of decoding a multiview video, the method comprising: receiving multiview image streams that configure the multiview video; obtaining, from a predetermined data unit header comprising information of a base-view picture comprised in a base-view image stream, picture order count (POC) information of the base-view picture; determining, using the POC information of the base-view picture, a POC of the base-view picture, based on an instantaneous decoding refresh (IDR) picture of a base-view; and determining, using the POC of the base-view picture, a POC of an additional-view picture that is comprised in a same access unit as the base-view picture and is transmitted, wherein the determining of the POC of the base-view picture comprises using the obtained POC information of the base-view picture to check if the base-view picture is not an IDR picture but is a Random Access Point (RAP) picture or a non-RAP picture, and: if the base-view picture is a RAP picture then obtaining first POC information and second POC information from the predetermined data unit header, wherein the first POC information is used to determine MSBs of the POC of the RAP picture, and the second POC information is used to determine LSBs of the POC of the RAP picture, if the base-view picture is a non-RAP picture then determining the POC of the non-RAP picture based on an MSB of a previous picture and LSB information that is included in the transmitted data unit, and wherein the determining of the POC of the additional-view picture comprises equally setting the POC of the additional-view picture to the POC of the base-view picture.
