Abstract

Connection used when a video game is executed among several persons is simplified, by a communication apparatus that includes a execution unit (10), a number of display units (21A, 22A, . . . ) for displaying a video image based on the program executed by the execution unit (10), a number of operation units (21B, 22B, . . . ) for instructing execution of the game program in the execution unit, and a communication control unit (11) for performing data communication between the execution unit, the display units, and the operation units, defining predetermined frame cycles as data communication states, setting a period in which isochronous transfer is performed in each frame cycle and a period in which asynchronous transfer is performed in each frame cycle, performing communication in divided slots for transmitting video data to the respective display units in the period in which isochronous transfer is performed in each frame cycle, and independently communicating operation data from the respective operation units by the respective slots in the period in which asynchronous transfer is performed in each frame cycle.
