Abstract
A transfer-rate computing component computes a transfer rate of an output from a digital video tape recorder component to output the same through a packet conversion component. Child units, which are newly connected to a bus, output data of the transfer rate subsequent to a request command of a bus use right. A total transfer-rate computing component of a parent unit computes a total transfer rate of the data which are transmitted through the bus. An arbitration control part judges whether or not the total transfer rate exceed the maximum transfer rate which is set in the bus. Only when the total transfer rate does not exceed the maximum transfer rate, a command transmission component issues a bus use permission right, to accept the transmission of data from newly connected child units. In this manner, when a new unit or device is connected to the bus and also when connection of the bus is turned off, synchronous transfer is assured.
