  • Publication number: 20240348839
    Abstract: Disclosed are a method of encoding a division block in video encoding and a method of decoding a division block in video decoding. An input picture is divided into encoding unit blocks. The encoding unit blocks are divided into sub-blocks. The sub-blocks are encoded by selectively using at least one of intra prediction encoding and inter prediction encoding. A decoding process is performed through a reverse process of the encoding method. When pixel values of an encoding unit block are encoded in video encoding, the flexibility in selecting an encoding mode is increased and the efficiency of encoding is increased.

  • Publication number: 20240339858
    Abstract: In a system for setting current capacity of a charging cable for supply of battery power from one electric vehicle to another electric vehicle, a discharge controller is provided in a supply vehicle to discharge a battery of the supply vehicle to supply battery power to a target vehicle. A charge controller is provided in the target vehicle to charge a battery of the target vehicle with battery power supplied from the supply vehicle. A charging cable part electrically connects the supply vehicle and the target vehicle. The discharge controller is configured to perform control so that a discharging current of the charging cable part is set by detecting an allowable charging current of the charging cable part connected to the supply vehicle and comparing the allowable charging current with a predetermined maximum current outputtable from the supply vehicle.
