Abstract

Appropriate control is performed when communication is performed between a plurality of information processing devices. An information processing device performs real-time image transmission with another information processing device according to a Wi-Fi CERTIFIED Miracast specification. The information processing device includes a control unit. The control unit performs control such that setting request information for performing a setting related to the real-time image transmission is received from the other information processing device via an access point. The control unit performs control such that a setting request for performing the setting based on the setting request information is transmitted to the other information processing device through direct communication.

First claim

The invention claimed is:

1. An information processing device that performs real-time image transmission with another information processing device according to a Wi-Fi CERTIFIED Miracast specification, comprising:
circuitry configured to
receive setting information via an access point or through direct communication with the another information processing device for performing a setting related to the real-time image transmission from the other information processing device via the access point or through the direct communication, the setting information indicating a High-Bandwidth Digital Content Protection System (HDCP) capability and being generated by the another information processing device based on information exchanged via the access point or through the direct communication; and
transmit a setting request for performing the setting based on the setting information to the another information processing device.

2. The information processing device of claim 1 , wherein
the circuitry is configured to transmit the setting request to the another information processing device through the direct communication with the another information processing device.

3. The information processing device of claim 2 , wherein
the circuitry is configured to perform control such that, when switching between a connection state with the another information processing device via the access point and a connection state with the another information processing device through the direct communication, a connection process is performed using at least one of port information and IP information related to a connection before the switching.

4. The information processing device of claim 3 , wherein
the circuitry is configured to perform control such that an image displayed on a predetermined region in a display is transmitted through a wireless transmission path of a low frequency band, and an image displayed on a region larger than the predetermined region in the display is transmitted through a wireless transmission path of a high frequency band.

5. The information processing device of claim 2 , wherein
the circuitry is configured to perform control such that image transmission according to the Wi-Fi CERTIFIED Miracast specification is performed through the direct communication after the setting request is transmitted to the another information processing device.

6. The information processing device of claim 2 , wherein
the circuitry is configured to perform control such that the setting request is transmitted to the another information processing device through the direct communication based on a manipulation of a user.

7. The information processing device of claim 2 , wherein
the circuitry is configured to perform control such that, when there is a plurality of information processing devices configured to perform image transmission through the direct communication, the setting request is transmitted to the another information processing device through the direct communication based on a predetermined order.

8. The information processing device of claim 7 , wherein
the circuitry is configured to perform control such that, when the permission information indicating that the connection is permitted is received, at least one of image data and audio data is received from the another information processing device via the access point other than the access point or the base station and output.

9. The information processing device of claim 2 , wherein
the circuitry is configured to perform control such that information for performing the direct communication is interchanged using near field communication.

10. The information processing device of claim 1 , wherein
the circuitry is configured to exchange capability information related to the information processing device with the another information processing device via the access point, and
the another information processing device generates the setting information based on the capability information.

11. The information processing device of claim 1 , wherein
the circuitry is configured to perform control such that permission information indicating whether or not a connection with the another information processing device via an access point other than the access point or a base station is permitted is interchanged via the access point, and when the permission information indicating that the connection is permitted is received, an interchange with the another information processing device via the access point other than the access point or the base station is performed.

12. An information processing device that performs real-time image transmission with another information processing device according to a Wi-Fi CERTIFIED Miracast specification, comprising:
circuitry configured to
transmit setting information via an access point or through direct communication with the another information processing device for performing a setting related to the real-time image transmission to the other information processing device via the access point or through direct communication, the setting information indicating a High-Bandwidth Digital Content Protection System (HDCP) capability and being generated by the information processing device based on information exchanged via the access point or through the direct communication; and
receive a setting request for performing the setting based on the setting information from the another information processing device.

13. The information processing device of claim 12 , wherein
the circuitry is configured to receive the setting request from the another information processing device through direct communication with the another information processing device.

14. An information processing system for performing real-time image transmission between a first information processing device and a second information processing device according to a Wi-Fi CERTIFIED Miracast specification, the system comprising:
the first information processing device configured to
transmit setting information via an access point or through direct communication with the another information processing device for performing a setting related to the real-time image transmission to the second information processing device via the access point or through the direct communication, the setting information indicating a High-Bandwidth Digital Content Protection System (HDCP) capability and being generated by the information processing device based on information exchanged via the access point or through the direct communication; and

the second information processing device configured to
receive the setting information from the first information processing device via the access point or through the direct communication; and
transmit a setting request for performing the setting based on the setting request information to the first information processing device, wherein

the first information processing device is configured to receive the setting request for performing the setting based on the setting information from the second information processing device.

15. The system of claim 14 , wherein
the second information processing device is configured to transmit the setting request to the first information processing device through the direct communication with the first information processing device.
