Abstract
Abstract A custom playlist to be played by a digital audio/visual actuator device may be easily created and modified through use of an effective human interface on an external device, such as a personal computer. Tracks, easily identifiable by their track index identifier and the TOC of the digital storage device on which they are stored, are selected by the user or by an automated method and added to a playlist file. Once the playlist is created, the playlist file is stored to non-volatile memory of the digital audio/visual actuator device. The playlist may then be easily modified if so desired by performing such functions as adding tracks, deleting tracks, and rearranging tracks of the playlist through the interface of the external device. The playlist may be played by the digital audio/visual actuator device at any time after it has been created and the digital audio/visual actuator device may be controlled by a remote control unit to actuate the playlist if so desired.
