Abstract

The display of very high definition still images on a high definition television is achieved through the decryption of received images within a DRM capable decryption device embedded within a high definition TV. The decryption device stores a pre-set decryption key, decrypts the incoming high definition still image content, and applies pre-set licensing parameters against the decrypted content. If the license for the encrypted content is determined to be valid the very high definition still images are displayed on the TV, otherwise the TV will display a lack of authorization message if the licensing is determined to be not valid. The embedded DRM decryption device is capable of determining and enforcing a number of licensure conditions for any and all received encrypted imagery. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

Claims

1. A method for display of high definition still image content on a television display, the method comprising:

receiving encrypted high definition still image content at a television display device;

determining whether the television display device contains a license to display the high definition still image content;

decrypting the high definition still image content within the television display device if the license is determined to be valid; and

displaying the high definition still image content.

2. The method of claim 1, wherein the encrypted high definition still image is received from a content provider such as a broadcaster, cable service provider, photographer, art gallery, library, museum, or individual provider.

3. The method of claim 1, wherein the decryption is performed by separate device installed within the television display device.

4. The method of claim 1, wherein the license determining step is performed by a Digital Rights Management (DRM) algorithm installed within the television display device.

5. The method of claim 4, wherein the license validity is determined by the DRM algorithm to be time-limited;

and

license timing and transfer is managed by a 3^rd party.

6. The method of claim 4, wherein the license validity is determined by the DRM algorithm to provide for limited sharing for a pre-set number of copies.

7. The method of claim 1, wherein the high definition still image content is provided at a minimum format of 3500 pixels by 1800 pixels.

8. The method of claim 1, wherein the displayed message indicating lack of authorization is also transmitted to the service provider.

9. The method of claim 1, wherein the TV displays a message indicating a lack of authorization if the license is not valid.

10. A system for the display of high definition still images, the system comprising:

a high definition display device;

an input channel through which high definition still image content is received by the high definition display device;

a decryption device operable to store a pre-set decryption key, decrypt incoming high definition still image content, and apply licensing parameters against the decrypted content; and

a display capable of displaying the decrypted content if the licensing is determined to be valid, otherwise displaying a lack of authorization message if the licensing is determined to be not valid.

11. The system of claim 10, wherein the display device is a high definition television.

12. The system of claim 10, wherein the decryption device is installed within, and integral to, the high definition television.

13. The system of claim 10, wherein the application of licensing parameters is performed by a DRM algorithm installed within the decryption device.

14. The system of claim 10, wherein the display is capable of displaying still image content at a minimum format of 3500 pixels by 1800 pixels.

15. The system of claim 10, wherein the high definition still image content is transmitted to the high definition television by a broadcaster, cable service provider, photographer, art gallery, library, museum, or individual provider.

16. A computer readable electronic storage medium installed within a display device for storing instructions for displaying high definition still images on a display, comprising:

receiving encrypted high definition still image content at a display device;

determining whether the display device contains a license to display the high definition still image content;

decrypting the high definition still image content within the display device if the license is determined to be valid; and

displaying the high definition still image content.

17. The computer readable storage medium of claim 16, wherein the display device is a high definition television.

18. The computer readable storage medium of claim 16, wherein the encrypted high definition still image is received from a content provider such as a broadcaster, cable service provider, photographer, art gallery, library, museum, or individual provider.

19. The computer readable storage medium of claim 16, wherein the license determining step is performed by a Digital Rights Management (DRM) algorithm installed within the television display device.

20. The computer readable storage medium of claim 16, wherein the license validity is determined by the DRM algorithm to be time-limited;

and

license timing and transfer is managed by a 3^rd party.

21. The computer readable storage medium of claim 16, wherein the license validity is determined by the DRM algorithm to provide for limited sharing for a pre-set number of copies.

22. The computer readable storage medium of claim 16, wherein the high definition still image content is provided at a minimum format of 3500 pixels by 1800 pixels.

23. The computer readable storage medium of claim 16, wherein the displayed message indicating lack of authorization is also transmitted to the service provider.

24. The computer readable storage medium of claim 16, wherein the TV displays a message indicating a lack of authorization if the license is not valid.
