Abstract: A transmission method includes: generating one or more transfer frames that each store one or more streams used for content transfer; and transmitting the one or more generated frames through broadcast, each of the one or more streams storing one or more second transfer units, each of the one or more second transfer units storing one or more first transfer units, and each of the one or more first transfer units storing one or more Internet Protocol (IP) packets. In at least one stream among the one or more streams, each of the first transfer units positioned at a head contains reference clock information indicating time used for reproduction of the content.

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 according to one aspect of the present disclosure encodes a block of an image, and includes a processor and memory connected to the processor. Using the memory, the processor partitions a block into a plurality of sub blocks and encodes a sub block included in the plurality of sub blocks in an encoding process including at least a transform process or a prediction process. The block is partitioned using a multiple partition including at least three odd-numbered child nodes and each of a width and a height of each of the plurality of sub blocks is a power of two.

Abstract: There is provided a decoding method for decoding an image, the method including: transmitting a request for an image to an external apparatus; receiving a coded signal corresponding to the image that has been requested and including a first signal and a second signal, and storing the coded signal in a storage; decoding the first signal and the second signal included in the coded signal; and displaying a first image decoded from the first signal in a first region of a screen, and displaying a second image decoded from the second signal in a second region of the screen. The second signal is a signal that has been selected by the external apparatus for a decoding apparatus from among a plurality of candidates for the second signal.

Abstract: An image decoder includes circuitry and a memory connected to the circuitry. In operation, the circuitry decodes a first bitstream to acquire a first image, decodes a second bitstream to acquire specification information specifying a particular region in the first image and a second image containing image data for the particular region, and generates a third image based on the first image, the specification information, and the second image.

Abstract: An encoder includes circuitry and memory. Using the memory, the circuitry, in inter prediction processing: derives a first motion vector of a current block to be processed, using a motion vector of a previous block which has been previously processed; derives a second motion vector of the current block by performing motion estimation in the vicinity of the first motion vector; and generates a prediction image of the current block by performing motion compensation using the second motion vector.

Abstract: An encoder includes circuitry and memory coupled to the circuitry. In operation, the circuitry determines one or more tiles included in a picture and one or more subpictures included in the picture, according to a constraint condition that each tile of the one or more tiles includes at least one subpicture of the one or more subpictures entirely and the each tile does not include another subpicture of the one or more subpictures partially.
