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 method of automatically updating a podcast stored on a client device, comprising:

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

if it is determined from the episode information that there is a new episode of the podcast and it is determined that the podcast is active, then

updating the podcast at the client device with the new episode.

2. The method as recited in claim 1, further comprising:

accessing the episode information from a host computer.

3. The method as recited in claim 1, further comprising:

determining that the podcast is active comprising;

determining if a user is interested in the podcast, wherein if it is determined that the user is interested in the podcast, then the podcast is determined to be active, otherwise the podcast is determined to be not active.

4. The method as recited in claim 3, further comprising:

determining if podcast is active comprising;

determining if an episode download count is greater than an integer N;

if the episode download count is determined to be greater than the integer N, then determining if more than M days have elapsed since a date of initial episode download;

if it is determined that more than M days have elapsed since the date of the initial episode download, then determining if the client device has been active since the date of initial episode download; and

if it is determined that the client has been active since the date of the initial episode download, then the podcast is determined to be inactive.

5. The method as recited in claim 4, further comprising:

determining if a reset condition exists; and

if it is determined that the reset condition exists, then

resetting at least one of the following;

the episode download count and the number of days having passed since the occurrence of the initial episode download.

6. The method as recited in claim 1, wherein said episode information is included in a portable subscription file that is stored at the client device.

7. A portable media player, comprising:

a storage device that stores at least a podcast having episodes;

a communication port capable of bi-directional communication with a device other than the portable media player; and

a processor coupled with the storage device that automatically updates the podcast stored on a client device by,

accessing episode information for the podcast, and

if it is determined that there is a new episode of the podcast and it is determined that the podcast is active, then

updating the podcast with the new episode.

8. The portable media player as recited in claim 7, wherein said portable subscription file is adapted to pass subscription information through a data network from the client device to at least another client device without interaction with a host device, thereby allowing the other client device to subscribe to the podcast.

9. The portable media player as recited in claim 7, further comprising:

accessing the episode information from a host computer.

10. The portable media player as recited in claim 7, further comprising:

determining that the podcast is active comprising;

determining if a user is interested in the podcast, wherein if it is determined that the user is interested in the podcast, then the podcast is determined to be active, otherwise the podcast is determined to be not active.

11. The portable media player as recited in claim 7, further comprising:

determining if podcast is active comprising;

determining if an episode download count is greater than an integer N;

if the episode download count is determined to be greater than the integer N, then determining if more than M days have elapsed since a date of initial episode download;

if it is determined that more than M days have elapsed since the date of the initial episode download, then determining if the client device has been active since the date of initial episode download; and

if it is determined that the client has been active since the date of the initial episode download, then the podcast is determined to be inactive.

12. The portable media player as recited in claim 11, further comprising:

determining if a reset condition exists; and

if it is determined that the reset condition exists, then

resetting at least one of the following;

the episode download count and the number of days having passed since the occurrence of the initial episode download.

13. The portable media player as recited in claim 7, wherein said episode information is included in a portable subscription file that is stored at the client device.

14. A computer program product executable by a processor for automatically 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 the new episode if it is determined from the episode information that there is a new episode of the podcast and it is determined that the podcast is active.

15. The computer program product as recited in claim 14, further comprising:

computer code for accessing the episode information from a host computer.

16. The computer program product as recited in claim 15, further comprising:

computer code for determining that the podcast is active comprising;

computer code for determining if a user is interested in the podcast, wherein if it is determined that the user is interested in the podcast, then the podcast is determined to be active, otherwise the podcast is determined to be not active.

17. The computer program product as recited in claim 16, further comprising:

computer code for determining if podcast is active comprising;

computer code for determining if an episode download count is greater than an integer N;

computer code for determining if more than M days have elapsed since a date of initial episode download if the episode download count is determined to be greater than the integer N;

computer code for determining if the client device has been active since the date of initial episode download if it is determined that more than M days have elapsed since the date of the initial episode download; and

computer code for determining that the podcast is inactive if it is determined that the client has been active since the date of the initial episode download.

18. The computer program product as recited in claim 17, further comprising:

computer code for determining if a reset condition exists; and

computer code for resetting at least one of the following;

the episode download count and the number of days having passed since the occurrence of the initial episode download if it is determined that the reset condition exists.

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

20. The computer program as recited in claim 14, further including:

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