    • PURPOSE: Video encoding and decoding efficiency is increased. CONSTITUTION: A plurality of spacious candidate prediction moving vector-related information is determined from an around prediction block of a prediction object block. Time candidate prediction moving vector-related information is determined based on the plurality of spacious candidate prediction moving vector-related information. A candidate prediction moving vector list is formed based on the time candidate prediction moving vector-related information and the spacious candidate prediction moving vector-related information. A moving vector is determined based on final prediction moving vector index information among candidate prediction moving vector list.

    • PURPOSE: A method for transmitting a multiview video and depth image information to an MPEG-2 transport stream and a device thereof are provided to transmit the MPEG-2 transport stream by including the multiview video and the depth image information in the MPEG-2 transport stream. CONSTITUTION: A packet generating unit generates an MPEG-2 TS(Transport Stream) packet. The packet includes a multiview video stream, an additional video stream corresponding to the multiview video stream, and interpretation information about the additional video stream. A transmitting unit(250) transmits an MPEG-2 TS by using the packet. The interpretation information includes a view information about the multiview video stream and a synthesis parameter for the synthesis of images in a virtual view using a mapping relation of a depth image(220) and a multiview video.
