Abstract
In a home audio visual network including a plurality of devices coupled via an IEEE 1394 bus, a system for accessing a media changer mechanism of a multi-item media player. The multi-item media player stores a plurality of media items and can play any of the plurality of media items. A media changer mechanism having a plurality of slots for storing the plurality of media items is included within the multi-item media player. A computer system is built into the multi-item media player. A software based media changer model executes on the computer system, and in turn, causes the computer system to implement a method of accessing the media changer mechanism. In so doing, the computer system interfaces with a plurality of devices coupled to the multi-item media player via an IEEE 1394 communications link of an IEEE 1394 based network and provides a standardized command set for the media changer mechanism. The media changer model provides a set of standardized commands that allow the plurality of devices on the network to access the media changer mechanism and access any of the plurality of media items stored therein.
