5. The method of claim 1 further comprising, by the accessory:
playing the audio track; and
during playing of the audio track, displaying the image at a time determined based on a timestamp associated with the image.
6. The method of claim 1 wherein requesting the image includes sending to the media player a request that identifies the image by reference to a track identifier and a timestamp.
7. The method of claim 1 wherein requesting the image includes sending to the media player a request identifying the image by reference to a track identifier, a timestamp, and the specified artwork format.
8. An accessory comprising:
an interface configured to communicatively couple the accessory to a media player configured to store an audio track and one or more images associated with the audio track, wherein each of the one or more images has a timestamp associated therewith, the timestamp indicating a time during playback of the audio track at which the image is to be displayed; and
control logic configured to:
obtain from the media player via the interface a list of artwork formats supported by the media player;
specify to the media player via the interface one of the artwork formats from the list of artwork formats supported by the media player;
obtain from the media player via the interface a list of the one or more images associated with the audio track, wherein the list includes only images that are available in the specified artwork format;
subsequently to obtaining the list of one or more images, select an image from the list to be displayed during playback of the audio track; and
subsequently to selecting the image from the list, obtain the image from the media player via the interface.
9. The accessory of claim 8 wherein the control logic is further configured to play the audio track and to display the image during playing of the audio track at a time determined based on a timestamp associated with the image.
10. The accessory of claim 8 wherein each artwork format specifies dimensions of an image.
11. The accessory of claim 8 wherein each artwork format specifies a pixel format for an image.
12. A system comprising:
a media player configured to store an audio track and one or more images associated with the audio track, wherein each of the one or more images has a timestamp associated therewith, the timestamp indicating a time during playback of the audio track at which the image is to be displayed; and
an accessory communicatively coupled to the media player,
wherein the accessory is configured to:
obtain from the media player a list of artwork formats supported by the media player;
specify to the media player one of the artwork formats from the list of artwork formats supported by the media player;
obtain from the media player a list of the one or more images associated with the audio track, wherein the list includes only images that are available in the specified artwork format;
subsequently to obtaining the list of one or more images, select an image from the list to be displayed during playback of the audio track; and
subsequently to selecting the image from the list, obtain the image from the media player.
13. The system of claim 12 wherein the accessory is further configured to play the audio track and to display the image during playing of the audio track at a time determined based on a timestamp associated with the image.
14. A machine-readable storage medium having stored thereon a series of instructions which, when executed by a processing component of an accessory configured to be communicatively coupled to a media player, cause the processing component of the accessory to:
obtain from the media player a list of artwork formats supported by the media player;
specify to the media player one of the artwork formats from the list of artwork formats supported by the media player;
obtain from the media player a list of one or more images associated with an audio track, wherein each image in the list has a timestamp associated therewith, the timestamp indicating a time during playback of the audio track at which the image is to be displayed, and wherein the list of one or more images includes only images that are available in the specified artwork format;
subsequently to obtaining the list of one or more images, select an image from the list to be displayed during playback of the audio track;
subsequently to selecting an image from the list, request the image from the media player; and
receive the image from the media player.
15. The machine-readable storage medium of claim 14 wherein the series of instructions further cause the processing component to play the audio track and to display the image during playing of the audio track at a time determined based on a timestamp associated with the image.
16. A media player comprising:
a storage device configured to store an audio track and one or more images associated with the audio track, wherein each of the one or more images has a timestamp associated therewith, the timestamp indicating a time during playback of the audio track at which the image is to be displayed;
an interface configured to communicatively couple the media player with an accessory; and
control logic configured to:
send to the accessory via the interface a list of artwork formats supported by the media player;
receive from the accessory via the interface a specification of one of the artwork formats from the list of artwork formats supported by the media player;
send to the accessory via the interface a list of the one or more images associated with audio track, wherein the list includes only images that are available in the specified artwork format;
subsequently to sending the list of the one or more images, receive from the accessory via the interface a selection made by the accessory of an image from the list to be displayed during playback of the audio track; and
