wherein glyph metrics comprise information about glyphs to be displayed on the remote control device indicated by the master unit in the request, the glyphs including symbols, images and characters, and

wherein the display metrics generated by the master unit and provided to the portable remote control device define a manner in which the glyphs are to be displayed on the display screen including spacing to enhance readability.

2. The system of claim 1, wherein the master unit wirelessly receives the glyph metrics from the remote control device and generates the display metrics for wireless communication to the portable remote control device based on the glyph metrics,

wherein in further response to the user action sent from the remote control device:

the display rendering module renders images used in a visual representation of the data to the display screen based the display metrics.

3. The system of claim 2, wherein the remote control device includes a user interface separate from the display that operates in a menu-driven fashion, the master unit defining the functionality of the user interface, and

wherein the display metrics define a manner in which a content item or character is displayed on the display screen, the display metrics including spacing to enhance readability of a content item of character on the display screen.

4. A method to display media content data to a user for playback of selected digital media on a playback device via a playback unit, the method including:

at the playback unit,

receiving media content data from a media storage device, the media content data identifying media available for playback on the playback device; and

processing the media content data to generate display metrics based on the media content data, the display metrics being associated with a display screen of a remote control device that is separate from the playback unit, and

at the remote control device,

wirelessly receiving the display metrics communicated from the playback unit; and

displaying the media content data on the display screen based on the display metrics,

wherein the display metrics are generated by the playback unit in response to a user action to display data, the user action sent from the remote control device,

wherein the remote control device is configured to transmit glyph metrics to the playback unit for use by the playback unit in calculating display metrics for use by the remote control device in displaying the data, the data describing media content playable on a media player controlled by the playback unit,

wherein the playback unit is configured to transmit a request for the glyph metrics to the remote control device in response to the user action sent from the remote control device,

wherein the remote control device is configured to responsively retrieve the glyph metrics from a table and transmit the retrieved glyph metrics to the mater unit,

wherein glyph metrics comprise information about glyphs to be displayed on the remote control device indicated by the playback unit in the request, the glyphs including symbols, images and characters, and

wherein the display metrics generated by the playback unit and provided to the portable remote control device define a manner in which the glyphs are to be displayed on the display screen including spacing to enhance readability.

5. The method of claim 4, which includes processing the media content data based on both the media content data and the glyph metrics,

wherein the method further comprises:

rendering, by the remote control device, images used in a visual representation of the media content data to the display screen based the display metrics.

6. The method of claim 5, which includes wirelessly communicating the glyph metrics from the remote control device to the playback unit.

7. The method of claim 6, wherein the glyph metrics are associated with glyphs used in the visual representation of data on the display screen and includes glyph metrics including physical dimensions occupied by an associated glyph when displayed on the display screen, and

wherein the display metrics define a manner in which a content item or character is displayed on the display screen, the display metrics including spacing to enhance readability of a content item of character on the display screen.

8. The method of claim 7, wherein the media content data identifies a plurality of media files and is arranged in a content hierarchy, the method including processing a title of a media file based on the glyph metrics to generate the display metrics that define a manner in which the title is displayed on the display screen.

9. The method of claim 7, which includes processing a group description of a plurality of media files in the content hierarchy based on the glyph metrics to generate the display metrics that define a manner in which the group description is displayed on the display screen.

10. The method of claim 7, which includes at the playback unit determining at least one of a spacing between adjacent glyphs, and a proposed position of each glyph on the display screen.

11. The method of claim 7, which includes at the remote control device retrieving a glyph from a corresponding font table and placing the glyph on the display screen based on the display metrics received from the playback unit.
