<p>There is provided a connection control apparatus (10) which, even when a plurality of such connection control apparatuses are connected to a bus such as the 1394 bus through which packet-based bidirectional serial communication is possible and to which a plurality of AV devices can be connected, makes it possible to know to which connection control apparatus the right of controlling each device connected to the bus belongs by collecting information about the control status of each connection control apparatus, thereby to carry out a high level of management of connections to and controls of the bus. Each connection control apparatus (10) connected to a bus, through which packet-based bidirectional serial communication is possible and to which a plurality of AV devices can be connected, comprises a control flag register (44) and a control information register (46) for storing the status of connection of the present device through the bus to other devices as well as the status of connection of the other devices to one another through the bus. <IMAGE></p> |
