The multi item media player stores the multiple media items, it is possible to operate the optional item of the multiple media items. It can have the media changer feature which possesses the multiple slots in order to store the multiple media items, inside the multi item media player. The computer system is constructed inside the multi item media player. The media changer model which is based on the software operates on the computer system, the computer system of the mataso, tries to be able to implement the manner which is accessed media changer feature. At that time, the computer system through the IEEE1394 communication link of the network which is based on IEEE1394 forms the interface of the multiple devices which are jointed to the multi item media player, gives the command set which is standardized in media changer feature. The command where the deck which it tries to be able to access the optional item among the multiple media items where the multiple devices with respect to network, access the media changer model, media changer feature, at the same time among those are stored is standardized is given.
