Abstract: A decoding method includes: determining two partitions in a current block according to a geometric partitioning mode; deriving an angular intra prediction mode from the geometric partitioning mode using a mapping relation between geometric partitioning modes and angular intra prediction modes; and predicting a first partition among the two partitions according to the angular intra prediction mode, in which in the deriving of the angular intra prediction mode, when a shape of the current block is square, a first mapping relation is used to derive the angular intra prediction mode, and when the shape of the current block is not square, a second mapping relation different from the first mapping relation is used to derive the angular intra prediction mode.

Abstract: The present disclosure relates to a user equipment (UE) that comprises a processor, which determines one among a plurality of mobility states for the UE, wherein the plurality of mobility states comprises at least three different mobility states. The processor determines one or more radio measurement quantities of a serving radio cell in which the UE is located. The processor determines whether or not to relax radio measurements on one or more neighbour radio cells, based on the determined mobility state of the UE and the determined one or more radio measurement quantities of the serving radio cell. A receiver and the processor of the UE perform the radio measurements on the one or more neighbour radio cells according to radio measurement requirements, when the processor determines not to relax the radio measurements on the one or more neighbour radio cells.

Abstract: An image encoder writes a first parameter and a second parameter to a bitstream, and derives a partition mode based on the first and second parameters. Responsive to the derived partition mode being a first partition mode, the image encoder executes the first partition mode including: splitting a block of a picture into a plurality of first blocks including a N×2N block sized N pixels by 2N pixels; splitting the N×2N block, wherein a ternary split is allowed to split the N×2N block in a vertical direction, which is a direction along the 2N pixels, into a plurality of sub blocks including at least one sub block sized N/4×2N, while a binary split is not allowed to split the N×2N block in the vertical direction into two sub blocks that are equally sized N/2×2N; and encoding the plurality of sub blocks.

Abstract: Provided is a fraud detection rule updating method enabling the updating of rules that serve as the basis for detecting malicious frames as necessary in an on-board network system. In an on-board network system equipped with multiple electronic control units (ECUs) that communicate via buses and fraud detecting ECUs that determine, based on fraud detection rules, whether messages transmitted on the buses conform to the rules, a fraud detection rule updating method is used in which delivery data including updated fraud detection rules is received from a server external to the on-board network system, and if a certain update condition is satisfied, the fraud detection rules in a fraud detecting ECU are updated to the updated fraud detection rules.

Abstract: A three-dimensional data encoding method includes: parsing a first syntax to determine, for each of at least one prediction tree in a slice, whether inter prediction or intra prediction is to be performed on the prediction tree, the prediction tree containing at least one three-dimensional point; and parsing a second syntax to determine a motion compensation mode to be performed on the prediction tree when the inter prediction is to be performed on the prediction tree.
