System and method for displaying information on the screen of a user interface device under the control of a digital audio playback device

摘要

A digital audio playback device (DAPD) includes: 1) an external interface for coupling to a connected processing system that executes a user interface application program that accesses and controls the digital audio playback device via the external interface; 2) a memory coupled to the external interface for storing a reverse DAPD application programming interface (API); and 3) a processor coupled to the memory and the external interface for executing the reverse DAPD API. The reverse DAPD API causes the processor to access and control a user interface operated by the user interface application program displayed on a monitor screen of the connected processing system.
