PROBLEM TO BE SOLVED: To perform update of a system which can be prevented from becoming a hinderance to the use of a user while suppressing the power consumption of remotely controlled equipment connected to a network. SOLUTION: This equipment is configured to independently manage the power sources of a network communication subsystem and the other system parts. The network communication sub-system itself interprets a TCP or UDP header, and discriminates a protocol which can be processed only by the communication sub-system and a protocol which is processed by the system part. Furthermore, the communication sub-system itself confirms the operating state of the system part, and acquires data including an update program in a proper timing, and performs the update of the system part.
