Abstract:
Provided is an encoder including: circuitry; and memory coupled to the circuitry, in which the circuitry: derives a prediction residual indicating a difference between a current block and a prediction image of the current block; performs primary transform on the prediction residual, and performs secondary transform on a result of the primary transform; performs quantization on a result of the secondary transform; and encodes a result of the quantization. In the performing of the secondary transform, when a matrix weighted intra prediction included in intra prediction and having prediction modes is used, the circuitry uses, as a transform set for the secondary transform, a common transform set shared among the prediction modes. The matrix weighted intra prediction generates the prediction image by performing matrix calculation on a pixel sequence obtained from pixel values of surrounding pixels of the current block.

Publication number: US20220030276A1

Abstract:
An encoder includes circuitry and memory. In both of a first type of residual coding where an orthogonal transform is applied to a current block and a second type of residual coding where the orthogonal transform is skipped, wherein when a number of CABAC processes is within an allowable range, the circuitry encodes coefficient information flags by CABAC, each of the coefficient information flags relating to a coefficient included in the current block; and otherwise, the circuitry skips the encoding of the coefficient information flags; and the circuitry encodes a remainder value of the coefficient with Golomb-Rice code when the coefficient information flags are encoded; and the circuitry encodes a value of the coefficient with the Golomb-Rice code when the plurality of coefficient information flags are not encoded, wherein the coefficient information flags are partially different between the first type of residual coding and the second type of residual coding.

Abstract:
A control method includes obtaining, from a terminal, reservation information including use start date and time of an electric-powered vehicle that a first user hopes to use; obtaining an amount of remaining battery of the electric-powered vehicle; determining, based on the amount of remaining battery, whether an amount of remaining battery of the electric-powered vehicle is no less than a predetermined value at the use start date and time; and transmitting, to the terminal, notification information indicating a result of the determining. For example, the determination includes calculating, based on a predetermined charging characteristic unique to a battery of the electric-powered vehicle, an amount of remaining battery to be held by the electric-powered vehicle at the use start date and time upon the electric-powered vehicle being charged at a charging station; and determining whether the amount of remaining battery of the electric-powered vehicle is no less than the predetermined value.
