1. A method of decoding a multi-view image, the method comprising: receiving a bitstream comprising information indicating whether each of pictures included in multi-view image sequences is a reference picture referred to by others of the pictures included in the multi-view image sequences for inter-view prediction and data about the multi-view image sequences; extracting the information and the data about the multi-view image sequences from the received bitstream; and determining whether pictures included in the data about the multi-view image sequences are to be used for inter-view prediction decoding based on the extracted information.
