Abstract

Particular embodiments generally relate to transferring data with first usage rights to a device and presenting the data by a receiving device by using different usage rights. The receiving device contacts one or more services that can determine what rights are available and can issue those rights to the receiving device. The receiving device can update the state across devices and services that maintain compliance with the usage rights.

Claims

1. A method for presenting content in a receiving device, the method comprising:

initiating transfer of the content from a sending device to the receiving device, wherein the content is associated with a first license, wherein the first license includes at least one digital rights management term;

in response to the initiating transfer, communicating with a license provider;

receiving a second license in association with the content, wherein the second license includes at least one license right that differs from the at least one digital rights management terms; and

presenting the content in accordance with at least one term in the second license.

2. The method of claim 1, wherein the receiving device complies with a Digital Transport Content Protection standard.

3. The method of claim 1, wherein the receiving device implements at least a portion of a Digital Rights Management (DRM) approach.

4. The method of claim 1, wherein initiating a transfer is caused by a sending device, wherein the sending and receiving devices each include a DRM approach, wherein the DRM approaches have at least one rights term that causes an interoperability issue.

5. The method of claim 1, wherein a license provider includes a License Coordination Service.

6. The method of claim 1, further comprising:

establishing a time duration;

storing at least a portion of the content for the time duration; and

obtaining a license in association with the content within the time duration.

7. The method of claim 6, further comprising:

establishing the time duration from the start of the initiating transfer of the content.

8. The method of claim 1, further comprising:

translating a term from the first license to the second license.

9. The method of claim 1, further comprising:

implementing a particular right from the first license into the second license whereby the particular right is not directly supported in a DRM associated with the second license.

10. The method of claim 9, wherein the particular right includes expiration of playback ability after a period of time.

11. An apparatus for presenting content in a receiving device, the apparatus comprising:

a processor;

a computer-readable storage device including one or more instructions executable by the processor for;

initiating transfer of the content from a sending device to the receiving device, wherein the content is associated with a first license, wherein the first license includes at least one digital rights management term;

in response to the initiating transfer, communicating with a license provider;

receiving a second license in association with the content, wherein the second license includes at least one license right that differs from the at least one digital rights management terms; and

presenting the content in accordance with at least one term in the second license.

12. A computer-readable storage device including instructions executable by a processor for presenting content in a receiving device, the computer-readable storage device comprising one or more instructions for:

initiating transfer of the content from a sending device to the receiving device, wherein the content is associated with a first license, wherein the first license includes at least one digital rights management term;

in response to the initiating transfer, communicating with a license provider;

receiving a second license in association with the content, wherein the second license includes at least one license right that differs from the at least one digital rights management terms; and

presenting the content in accordance with at least one term in the second license.
