Abstract: An encoder includes circuitry and memory coupled to the circuitry. In residual coding of a current block, the circuitry, in operation, encodes a subblock flag by Context-based Adaptive Binary Arithmetic Coding (CABAC) in both of a first type of residual coding where an orthogonal transform is performed and a second type of residual coding where the orthogonal transform is skipped, the subblock flag indicating whether a non-zero coefficient is included in a plurality of coefficients for a subblock within the current block, wherein a first syntax used for the first type of residual coding is different from a second syntax used for the second type of residual coding; and controls a number of CABAC processes, wherein the encoding of the subblock flag is not counted as the number of CABAC processes.

Abstract: A transmitting method stores data making up a coded stream into a predetermined data unit and transmits the stored data in the predetermined data unit. The transmitting method further generates presentation time information indicating a presentation time of the predetermined data unit, based on reference time information received from an external source; and transmits the predetermined data unit, first control information which includes the generated presentation time information, and second control information which includes leap second information indicating whether or not the presentation time information is a time that is before a leap second adjustment. A receiving method receives the predetermined data unit, first control information, and second control information; and reproduces the received predetermined data unit based on the first and second control information that are received.

Abstract: Provided is an encoder including circuitry and memory coupled to the circuitry. A prediction mode for a current block is an affine mode, and in operation, the circuitry: derives a base motion vector which is a motion vector to be used in a prediction process for the current block, and is a motion vector at an affine-mode control point in the current block; derives a first motion vector different from the base motion vector; derives a motion vector difference based on a difference between the base motion vector and the first motion vector; determines whether the motion vector difference is greater than a threshold; if so, modifies a second motion vector different from the base motion vector and the first motion vector, and if not, does not modify the second motion vector; and encodes the current block using the second motion vector modified or the second motion vector not modified.

Abstract: For a location displaced by four samples in a vertical direction or a horizontal direction from a current location, the encoder performs a first determination of determining only whether the location displaced by four samples is a TU boundary, where the current location is a sample location of a current sub-block boundary on which the determination process is to be performed. In the first determination, when it is determined that the location displaced by four samples is a TU boundary, the encoder sets a maximum filter length to a first value, and in the case otherwise, the encoder performs a second determination of determining whether a location displaced by eight samples in the vertical direction or the horizontal direction from the current location is a TU boundary.

Abstract: An encoder including circuitry and memory coupled to the circuitry. In both of a first case where an orthogonal transform is performed and a second case where the orthogonal transform is skipped, when a number of CABAC processes is within an allowable range, the circuitry: encodes a plurality of coefficient information flags by CABAC; and encodes a remainder value of the coefficient; and when the number of CABAC processes is not within the allowable range, the circuitry: skips the encoding of the plurality of coefficient information flags, wherein in the first case, the circuitry: converts the coefficient to a second coefficient by using a poszero value that is determined using a plurality of surrounding coefficients; and encodes a value of the second coefficient, and wherein in the second case, the circuitry: encodes the value of the coefficient.

Abstract: An encoder includes circuitry and memory coupled to the circuitry. The circuitry: assigns a picture level slice index and a subpicture level slice index to each of the slices, the picture level slice index being assigned at a picture level, the subpicture level slice index being assigned at a subpicture level; for each of the slices, encodes the subpicture level slice index of the slice into a slice header of the slice; and encodes each of the slices into a bitstream. The picture level slice index assigned to a current slice to be processed that is 10 included in a current subpicture to be processed is calculated by adding (i) the subpicture level slice index of the current slice and (ii) a total number of slices included in one or more subpictures that have been encoded prior to the current subpicture out of the subpictures.
