ABSTRACT:
In a system for carrying out communication between a plurality of apparatus connected using an IEEE 1394 serial bus etc., command register addresses are fixed from "FFFF F000 0B00h" to "FFFF F000 0D00h" and response register addresses are fixed from "FFFF F000 0D00h" to "FFFF F000 0DF0h". These addresses are then common to all of the apparatus connected to the bus. Then, while an arbitrary apparatus on the bus is sending a command to all of the remaining apparatus, the address of the command register is included in the command and this command is transmitted as a broadcast communication. This command is then stored at a command register having a common address within the apparatus that received the command. Thus, time setting and state setting etc. of each apparatus can be achieved.
