Abstract: An image encoder is provided, which includes circuitry and a memory coupled to the circuitry. The circuitry, in operation, performs a boundary smoothing operation along a boundary between a first partition having a non-rectangular shape (e.g., a triangular shape) and a second partition that are split from an image block. The boundary smoothing operation includes: first-predicting first values of a set of pixels of the first partition along the boundary, using information of the first partition; second-predicting second values of the set of pixels of the first partition along the boundary, using information of the second partition; weighting the first values and the second values; and encoding the first partition using the weighted first values and the weighted second values.

Abstract: An encoding device (100) is provided with a circuit and a memory connected to the circuit. In an operation, the circuit writes, into a bit stream, a first parameter indicating whether a prediction mode is (i) a multiplex prediction mode for generating a prediction image by superimposition between an inter-prediction image and an intra-prediction image of a to-be-processed block, or (ii) any one of a plurality of prediction modes including a triangle mode for generating a prediction image by dividing the to-be-processed block into triangular regions, and the circuit encodes the to-be-processed block in accordance with the prediction mode.

Abstract: An encoder (100) that encodes a current block in a picture includes circuitry and memory. Using the memory, the circuitry: splits the current block into a first sub block, a second sub block, and a third sub block in a first direction, the second sub block being located between the first sub block and the third sub block; prohibits splitting the second sub block into two partitions in the first direction; and encodes the first sub block, the second sub block, and the third sub block.

Abstract: ABSTRACT A decoder and a method is disclosed that decodes a current block in a picture. The decoder comprises circuitry and a memory. Using the memory, the circuitry performs a first inverse transform on inverse quantized coefficients of the current block using a first inverse transforrn basis without performing a second inverse transform, when the first inverse transform basis used for the first inverse transform is a discrete cosine inverse transform basis.

Abstract: Recorded in a recording medium are a video stream of standard-luminance range, and a video stream of high-luminance range that is a broader luminance range than the standard-luminance range, which are used selectively in accordance with a playback environment, 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, and a playlist file storing playback control information of content, playlist file including a management region where the playback control information relating to a main stream is stored, and an extended region. The management region stores first playback control information specifying that a video stream of the high-luminance range and a subtitle stream of the high-luminance range are to be played in combination. The extended region stores second playback control information specifying that a video stream of the standard-luminance range and a subtitle stream of the standard-luminance range are to be played in combination.

Abstract: A recording medium on which is recorded at least one video stream, the video stream being encoded video information, and a management information file (BD.INFO file) indicating an attribute pertaining to the entire recording medium. The management information file includes attribute information (is_HDR) indicating whether the dynamic range of the brightness of an initial video stream, which is the first among the at least one video stream to be played back when the recording medium is inserted into a playback device, corresponds to a first dynamic range (SDR) or a second dynamic range (HDR) greater than the first dynamic range.

Abstract: This image encoding method encodes at least one unit contained in a picture, and includes: a first flag generating step (S221) for generating a first flag indicating whether or not the times that a virtual decoder reads encoded data from a buffer for storing the encoded data are set in units of the units; a second flat generating step (S222) for, when the times are set in units of the units, generating a second flag indicating whether the intervals between the read times of the plurality of units are fixed or arbitrary; and a bitstream generation step (S223) for generating an encoded bitstream containing the encoded data, the first flag, and the second flag.
