Abstract

Application program interfaces for controlling an external media changer from a computer are provided. The application program interfaces allow for loading and identification of discs in a media changer. The application program interfaces can further allow for control of media changer functions such as locking of media changer elements and playback of disc content for discs in the media changer.

Claims

1. An application program interface for controlling an external media changer, comprising:

an identification component for determining at least one of a location, type, and identity of discs located in an external media changer;

a loading component for loading and unloading of discs into a media changer drive in the external media changer; and

a locking component for locking and unlocking of the media changer drive.

2. The application program interface of claim 1, further comprising:

a movement component, for moving discs between elements within the media changer.

3. The application program interface of claim 1, further comprising:

a status check component for providing the current status of the media changer.

4. The application program interface of claim 3, wherein the status check component provides the current status for one or more media changer elements in the media changer.

5. The application program interface of claim 1, wherein the discs are DVDs, audio CDs, data CDs, blank DVDs, or blank CDs.

6. The application program interface of claim 1, wherein the identification component further comprises a component for determining at least one of the type and identity of a disc located in an internal playback or storage device.

7. The application program interface of claim 1, further comprising an initialization component for initializing one or more elements of the external media changer.

8. The application program interface of claim 1, wherein the loading component further comprises an ejection component for ejecting a disc from the external media changer.

9. The application program interface of claim 8, wherein the ejection component further comprises a component for ejecting a disc located in an internal playback or storage device.

10. The application program interface of claim 1, further comprising:

a playback component for playing back content on a disc in the external media changer.

11. A computer readable medium having computer executable instructions embodied thereon for performing actions on an external media changer, the instructions providing a method comprising:

receiving identifying information for an external media changer;

determining at least one of a location, type, and identity of a disc located in an element of an external media changer; and

loading the disc into a media changer drive in the external media changer.

12. The computer readable medium of claim 11 having instructions embodied thereon, further comprising:

unloading the disc from the media changer drive.

13. The computer readable medium of claim 11 having instructions embodied thereon, wherein receiving identifying information comprises receiving at least one of

product data about the media changer,

the current status of the media changer,

the current status of one or more elements in the media changer, or

volume tag information about the one or more media changer elements.

14. The computer readable medium of claim 11 having instructions embodied thereon, further comprising:

moving the disc between elements in the media changer.

15. The computer readable medium of claim 11 having instructions embodied thereon, wherein the elements are selected from the group consisting of media changer drives and storage slots.

16. The computer readable medium of claim 11 having instructions embodied thereon, further comprising

ejecting a disc from the external media changer.

17. The computer readable medium of claim 11 having instructions embodied thereon, further comprising

determining at least one of a type and identity of a disc located in an internal playback or storage device.

18. The computer readable medium of claim 11 having instructions embodied thereon, further comprising:

playing back content on the disc.
