  • Patent number: 11943447
    Abstract: Disclosed herein are a decoding method and apparatus and an encoding method and apparatus that perform inter-prediction using a motion vector predictor. For a candidate block in a col picture, a scaled motion vector is generated based on a motion vector of the candidate block. When the scaled motion vector indicates a target block, a motion vector predictor of the target block is generated based on the motion vector of the candidate block. The motion vector predictor is used to derive the motion vector of the target block in a specific inter-prediction mode such as a merge mode and an AMVP mode.

    Abstract: A pedestal has two sides that are opposite one another and to which various charging boxes can be mounted and electrically connected. For instance, the pedestal can have the same charging boxes mounted to the two sides and electrically connected with a power system upon which the pedestal is positioned. Instead, two different charging boxes can be mounted to the two sides. Importantly, either or both charging boxes can be easily removed by appropriate personnel and alternatively replaced with other charging boxes if, for instance, the market for needing specific electrical charging has changed or if the population of electrical vehicles needing electrical charging has grown in a new direction, by way of example.
