Abstract: The invention provides an electronic equipment controlling apparatus and method and an electronic equipment controlling system by which functions of an electronic equipment can be utilized effectively. AV equipments are connected to a PC module by an IEEE 1394 cable. Each of the AV equipments includes a ROM in which information of function units built in the AV equipment is stored. Upon initialization, the PC module receives transmission of and stores the information of the function units of the AV equipments from the AV equipments. When an instruction to record data reproduced from a first one of the AV equipments onto a second one of the AV equipments is received, the PC module transfers data in accordance with the information of the function units stored therein and automatically searches for function units to be processed.

Abstract: The present invention relates to a technique to realize the copying operation without any deterioration of information by simplified operation on the occasion of copying information to a plurality of recording media from a source medium. A PC module registers an MD player module and a DAT player module as one group, then produces a unique group ID to this group and notifies this group ID to the MD player module and DAT player module. On the occasion of copying information to this group from the CD player module, the PC module adds the group ID and recording instruction to the reproduction instruction for the CD player module and then transmits the data to the 1394-cable. The CD player module which has received a command starts reproducing operation and transmits again the remaining part from which the command for own device is deleted to the 1394-cable.
