    Abstract: A transmitting method for transmitting encoded data obtained by hierarchically encoding a video image includes: generating an encoded stream that includes time information and the encoded data, the time information indicating a time at which decoding or displaying processing of the encoded data is performed, and transmitting the generated encoded stream, wherein the encoded data includes a plurality of sets each including a plurality of access units and the time information includes first time information which indicates a time at which the processing performed on a first access unit of the first set is performed and which is based on a reference clock, and second time information used to specify a time at which the processing performed on a second access unit of the second set is performed and which is based on the reference clock.

    Abstract: A recording medium includes a video stream of a standard-luminance range and a video stream of high-luminance range, which are used selectively in accordance with a playback environment. The recording medium also includes a subtitle stream of the standard-luminance range and a subtitle stream of the high-luminance range, which are used selectively in accordance with the playback environment. A playlist file includes a management region where playback control information relating to a main stream is stored, and includes an extended region. The management region stores first playback control information specifying playing of the video stream of the high-luminance range and the subtitle stream of the high-luminance range in combination. The extended region stores second playback control information specifying playing of the video stream of the standard-luminance range and the subtitle stream of the standard-luminance range in combination.

    Abstract: An encoder includes circuitry and memory connected to the circuitry. In operation, the circuitry: stores MV information and correction processing information into a FIFO buffer for an HMVP mode in association, the MV information being derived for a processed block and correction processing information being related to correction processing of a prediction image of the processed block; registers, in a prediction candidate list for a merge mode, one or more prediction candidates each being a combination of MV information and correction processing information, the prediction candidates including a prediction candidate which is a combination of the motion vector information and the correction processing information stored in the FIFO buffer; and selects a prediction candidate from the prediction candidate list when a current block is to be processed in the merge mode, and performs correction processing of a prediction image of the current block, based on the correction processing information.
