  • Patent number: 10642562
    Abstract: A display apparatus includes a plurality of surfaces, and a display device provided on at least one surface among the plurality of surfaces. A plurality of communication sections are arranged to correspond to at least two or more side surfaces with respect to the surface on which the display device is provided among the plurality of surfaces and configured to perform communication within a predetermined distance, each of the plurality of communication sections including different identification information. A control section is configured to perform control of the plurality of communication sections and the display device. When another display apparatus is connected to the display apparatus, the control section periodically performs time synchronization to synchronize an image displayed on the display device with an image displayed on a display device provided in the other display apparatus.

  • Patent number: 10244431
    Abstract: A radio communication method stores a plurality MAC frames for each of a plurality of destinations. The method decides the longest transmission time of transmission times needed to transmit the plurality of MAC frames to each of the plurality of destinations within a fixed period. The method generates a plurality of physical frames for the plurality of destinations to transmit them at the same time by connecting the plurality of MAC frames and adding additional information to each connected MAC frame so as to be a frame length equivalent to a transmission time equal to the longest transmission time.
