Abstract

A media player is presented that is capable of playing time-limited media files such as those made available through subscription-type digital rights management schemes. Upon accessing a protected media file, the present invention analyzes the appropriate license. If the license has not expired, but will expire soon, the media player will provide a notification of impending expiration to the user immediately before or during the playing of the media file. This notification can be audible, visual, or physical, such as through an audible beep, a visual notification on a display screen, or the activation of a vibration device.

Claims

1. A portable media player comprising:

a) a memory containing

i) content, and

ii) a license associated with the content, the license having an expiration time;

b) a clock;

c) an expiration notification logic component that provides notification external to the portable media player if the clock indicates that the license has not yet expired but will expire within a predetermined time frame.

2. The portable media player of claim 1, wherein the notification is of a form chosen from the set of:

an audible signal on an audible output mechanism of the media player, a visual signal displayed on a visual output mechanism on the media player, and a vibration created by a vibration device found in the media player.

3. The portable media player of claim 1, wherein the license is data stored separately from the content.

4. The portable media player of claim 1, wherein the license forms a portion of the data file containing the content.

5. The portable media player of claim 1, wherein the memory is a nonvolatile memory.

6. A method for verifying a time limited license for media content on a portable media player comprising:

a) analyzing a license for a media product about to be played;

b) determining whether the license will expire within a predetermined time frame but has not yet expired; and

c) if the determination in step b) is positive, creating a notification detectable outside of the media player indicated that the license for the media content will soon expire.

7. The method of claim 6, wherein the step of creating a notification takes the form of creating an audible signal on an audible output mechanism of the media player.

8. The method of claim 6, wherein the step of creating a notification takes the form of creating a visual signal displayed on a visual output mechanism on the media player.

9. The method of claim 6, wherein the step of creating a notification takes the form of creating a vibration by triggering by a vibration device found in the media player.
