Abstract

Improved podcasts and techniques that facilitate their use are disclosed. The improved techniques can pertain to creating, publishing, hosting, accessing, subscribing, managing, transferring, and/or playing podcasts. According to one aspect, a client application can subscribe to podcasts and then automatically monitor the podcasts for updates to be downloaded. In the event that user interest in a podcast becomes inadequate, downloading of further updates can be restricted. According to another aspect, a podcast can be subscribed to through use of a portable subscription file. According to still another aspect, podcast feeds can be enhanced to include segment elements and other metadata.

Claims

1. A portable media player, comprising:

a communication port adapted for communication with an external device other than the portable media player; and

a processor coupled with the communication port and adapted to update a podcast having episodes by accessing episode information for the podcast and then updating the podcast with a new episode if it is determined that there is a new episode of the podcast.

2. The portable media player of claim 1, further comprising:

a storage device that stores the podcast having episodes.

3. The portable media player of claim 1, wherein the processor is further adapted to determine whether the podcast is active.

4. The portable media player of claim 3, wherein said determining whether the podcast is active includes determining whether a user of the portable media player is interested in the podcast.

5. The portable media player of claim 3, wherein said determining whether the podcast is active includes determining whether an episode download count is greater than a threshold amount.

6. The portable media player of claim 3, wherein said determining whether the podcast is active includes determining whether a threshold number of days have elapsed since a date of an initial episode download.

7. The portable media player of claim 1, wherein the communication port is adapted for bi-directional communication with the external device.

8. The portable media player of claim 1, wherein said episode information is included in a portable subscription file that is stored at the client device.

9. A computer program product executable by a processor for updating a podcast stored on a client device, comprising:

computer code for accessing at the client device episode information for the podcast; and

computer code for updating the podcast at the client device with a new episode if it is determined from the episode information that the new episode of the podcast exists.

10. The computer program product of claim 9, further comprising:

computer code for determining whether the podcast is active.

11. The computer program product of claim 10, wherein the computer code for determining whether the podcast is active includes computer code for determining whether a user is interested in the podcast.

12. The computer program product of claim 10, wherein the computer code for determining whether the podcast is active includes computer code for determining whether an episode download count is greater than a threshold amount.

13. The computer program product of claim 10, wherein the computer code for determining whether the podcast is active includes computer code for determining whether a threshold number of days have elapsed since a date of an initial episode download.

14. The computer program product of claim 9, wherein said episode information is included in a portable subscription file that is stored at the client device.

15. A method of automatically updating a podcast, comprising:

accessing at a client device episode information for the podcast; and

updating the podcast at the client device with a new episode if it is determined from the episode information that the new episode of the podcast exists.

16. The method of claim 15, further comprising the step of:

determining whether the podcast is active.

17. The method of claim 16, wherein said step of determining whether the podcast is active includes determining whether a user is interested in the podcast.

18. The method of claim 16, wherein said step of determining whether the podcast is active includes determining whether an episode download count is greater than a threshold amount.

19. The method of claim 15, wherein said episode information is included in a portable subscription file that is stored at the client device.

20. The method of claim 19, further comprising the step of:

passing subscription information through a data network from the client device to at least one other client device without interaction with a host device, thereby allowing the one other client device to subscribe to the podcast.
