Abstract

To cause image information to be appropriately displayed among a plurality of information processing devices. An information processing device includes a wireless communication unit and a control unit. The wireless communication unit is configured to perform real-time image transmission with another information processing device according to a wireless fidelity (Wi-Fi) Certified Miracast specification. The control unit is configured to perform control in a manner that second image information to be displayed on a non-display region included in first image information transmitted from the other information processing device is acquired, and a combined image in which the first image information is combined with the second image information is displayed on a display unit.

First claim

The invention claimed is:

1. An information processing device, comprising:
circuitry configured to:
perform real-time image transmission with another information processing device according to a Wi-Fi Certified Miracast specification;
exchange, with the another information processing device, setting information and content protection information;
receive a first content information protected by a content protection system from the another information processing device, wherein the first content information includes a non-display region and a manipulation region, the first content information is generated by the another information processing device based on the setting information and the content protection information, the non-display region is a content managed under a copyright and is an image of a specific color, and the manipulation region is an image used for a user manipulation;
transmit confirmation information to a digital rights management (DRM) content server for accessing second content information to be displayed on the non-display region, the second content information being an image managed under a copyright;
receive permission information of permitting access to the second content information from the DRM content server, the permission information indicating that the information processing device is permitted access to the second contact content information under the copyright applying to the second content information, receive the second content information from the DRM content server;
combine the first content information and the second content information, wherein the manipulation region is displayed on top of the second content information;
and control a display to display the combined image in the non-display region.

2. The information processing device according to claim 1 , wherein the circuitry specifies the non-display region in the first content information based on command information related to the non-display region which is transmitted from the another information processing device.

3. The information processing device according to claim 2 , wherein the circuitry specifies the non-display region in the first content information based on a position and a size of the non-display region in the first content information which is included in the command information.

4. The information processing device according to claim 2 , wherein the circuitry acquires the second content information from the DRM content server based on address information included in the command information.

5. The information processing device according to claim 4 , wherein when the command information has been received, the circuitry transmits the confirmation information for accessing the second content information to the DRM content server, receives the permission information of permitting access to the second content information from the DRM content server, and then acquires the second content information from the DRM content server.

6. The information processing device according to claim 4 , wherein when the command information has been received, the circuitry transmits the confirmation information for the another information processing device to access the second content information to the DRM content server, receives the permission information of permitting access of the another information processing device to the second content information from the DRM content server, and then transmits the setting information for the another information processing device to acquire the second content information from the DRM content server to the another information processing device.

7. The information processing device according to claim 6 , wherein after transmitting the setting information to the another information processing device, the circuitry acquires the second content information from the DRM content server, and transfers the second content information to the another information processing device.

8. The information processing device according to claim 2 , wherein the circuitry performs display control of the combined image based on control information related to an image displayed on the non-display region which is included in the command information.

9. The information processing device according to claim 2 , wherein based on manipulation image information related to a manipulation image displayed on the non-display region which is included in the command information, the circuitry controls the manipulation image to be superimposed on the combined image.

10. The information processing device according to claim wherein the circuitry performs real-time image transmission with a plurality of other information processing devices, and the circuitry controls a simultaneous display of a plurality of the combined images related to a plurality of pieces of first content information transmitted from the plurality of other information processing devices on the display.

11. The information processing device according to claim 1 , wherein the content protection system is high-bandwidth digital content protection system (HDCP).

12. The information processing device according to claim 1 , wherein the setting information includes the content protection information.

13. The information processing device according to claim 1 , wherein the image of the specific color is a black image.

14. An information processing device, comprising:
circuitry configured to:
perform real-time image transmission with another information processing device according to a Wi-Fi Certified Miracast specification; exchange, with the another information processing device, setting information and content protection information;
generate a first content information based on the setting information and the content protection information, wherein the first content information includes a non-display region and a manipulation region, the non-display region is a content managed under a copyright and is an image of a specific color, and the manipulation region is an image used for a user manipulation;
transmit the first content information protected by a content protection system to the another information processing device; and
transmit information such that the another information processing device receives permission information of permitting access to second content information to be displayed on the non-display region from a digital rights management (DRM) content server, the second content information being an image managed under a copyright, the permission information indicating that the another information processing device is permitted access to the second content information under the copyright applying to the second content information, receives the second content information from the DRM content server, combines the first content information and the second content information such that the manipulation region is displayed on top of the second content information, and controls a display to display the combined image in the non-display region.

15. An information processing system, comprising:
a first information processing device; and
a second information processing device, wherein the first information processing device comprises first circuitry configured to perform real-time image transmission with the second information processing device according to a Wi-Fi Certified Miracast specification;
exchange, with the second information processing device, setting information and content protection information;
generate a first content information based on the setting information and the content protection information, wherein the first content information in
