The remote control device includes an input region that is operable to select from a plurality of entities for providing audio content to the audio playback device, and a display for displaying information associated with the entities for providing audio content. The remote control device is configured to request image files from the audio playback device for display on the display. The image files correspond to the entities for providing audio content. ## Claims ### Claim 1 A remote control device for controlling an audio playback device, the remote control device comprising: an input region operable to select from a plurality of entities for providing audio content to the audio playback device; a display for displaying information associated with the entities for providing audio content, wherein the remote control device is configured to request image files from the audio playback device for display on the display, and wherein the image files correspond to the entities for providing audio content, wherein the image files comprise text that has been rendered as an image by the audio playback device. ### Claim 2 (depends on 1) The remote control device of claim 1, wherein the remote control device is configured to: send a status request message to the audio playback device; and receive a status response message, responsive to the status request message, from the audio playback device, the status response message comprising a list of the image files for synchronization of the remote control device with the audio playback device. ### Claim 3 (depends on 2) The remote control device of claim 2, wherein, in response to the status response message, the remote control device is configured to send a separate get file request message to the audio playback device for each of the image files identified in the list of the image files, each get file request message comprising a request for a corresponding one of the image files. ### Claim 4 (depends on 2) The remote control device of claim 2, wherein the remote control device is configured to maintain a list of preset assignments, and wherein the status response message comprises preset information, which remote control device utilizes for updating the list of preset assignments. ### Claim 5 (depends on 1) The remote control device of claim 1, wherein the input region comprises a plurality of preset indicators, each preset indicator is configured to have assigned to it an entity associated with one of a plurality of digital audio sources for providing audio content to the audio playback device. ### Claim 6 (depends on 5) The remote control device of claim 5, wherein the preset indicators on the remote control device correspond to a set of preset indicators on the audio playback device. ### Claim 7 (depends on 5) The remote control device of claim 5, wherein the remote control device is configured to synchronize preset assignments with the audio playback device, wherein each of the preset assignments represents an assignment of an entity associated with one of the digital audio sources to a corresponding one of the preset indicators. ### Claim 8 (depends on 1) The remote control device of claim 1, further comprising a storage device, wherein the remote control device is configured to: receive compressed image files from the audio playback device; decompress the compressed image files; and store the decompressed image files on storage device. ### Claim 9 (depends on 8) The remote control device of claim 8, wherein the remote control device is configured to send a confirmation message to the audio playback device after each of the image files is saved on the storage device. ### Claim 10 An audio playback device configured to operably connect to a plurality of digital audio sources and controllable via a remote control device, the audio playback device comprising: a digital-to-analog converter configured to receive a digital representation of audio content from the digital audio sources and convert to analog form; an electro-acoustic transducer; wherein the audio playback device is configured to send image files to the remote control device for storage and display on the remote control device; wherein the image files comprise text that has been rendered as an image by the audio playback device. ### Claim 11 (depends on 10) The audio playback device of claim 10, wherein the audio playback device is configured to operably connect to a plurality of digital audio sources, and wherein the audio playback device further comprises a set of user-selectable preset indicators and each indicator being assigned to it an entity associated with the plurality of digital audio sources. ### Claim 12 (depends on 11) The audio playback device of claim 11, wherein the image files correspond to preset assignments, each of the preset assignments representing an assignment of an entity associated with one of the digital audio sources to a corresponding one of the preset indicators. ### Claim 13 (depends on 12) The audio playback device of claim 12, wherein the image files comprise icons associated with the digital audio sources. ### Claim 14 (depends on 10) The audio playback device of claim 10, wherein the image files are stored in compressed form on the audio playback device. ### Claim 15 (depends on 10) The audio playback device of claim 10, wherein the audio playback device is configured to send the image files to the remote control device in response to a get file request message received from the remote control device. ### Claim 16 (depends on 10) The audio playback device of claim 10, wherein the audio playback device further comprises a database that tracks which image files are stored on the remote control device. ### Claim 17 (depends on 16) The audio playback device of claim 16, wherein the database tracks which image files the remote control device has previously stored and which image files the remote control device needs from the audio playback device. ### Claim 18 (depends on 17) The audio playback device of claim 17, wherein the audio playback device is configured to update the database in response to communications from remote control device indicating that needed image files have been successfully stored on the remote control device. ### Claim 19 (depends on 10) The audio playback device of claim 10, wherein the audio playback device is configured to communicate with the remote control device via a Bluetooth LE connection. ### Claim 20 (depends on 17) The audio playback device of claim 17, wherein the audio playback device is configured to extract text from the database and render the extracted text as an image, wherein the image files comprise the rendered image of the extracted text.
