Abstract

Appropriate power consumption mode control is to be performed.

An information processing device is an information processing device that receives a stream for outputting image information from another information processing device through wireless communication, and includes a wireless communication unit and a control unit. The wireless communication unit performs communication with another information processing device so as to exchange the capability information about the information processing device and the capability information about the other information processing device. The control unit sets a power consumption mode in the other information processing device based on the capability information about the other information processing device.

Claims

1. An information processing device receiving a stream from another information processing device through wireless communication, the stream being for outputting image information,

the information processing device comprising:

a wireless communication unit configured to perform communication with the another information processing device, the communication being for exchanging capability information about the information processing device and capability information about the another information processing device; and

a control unit configured to perform control to set a power consumption mode in the another information processing device based on the capability information about the another information processing device.

2. The information processing device according to claim 1, wherein

the capability information about the another information processing device includes information indicating whether the another information processing device is a mobile device, and

the control unit performs control to set a low power consumption mode in the another information processing device based on the capability information about the another information processing device and management information for managing the another information processing device.

3. The information processing device according to claim 2, wherein the management information is information for managing identification information for identifying the another information processing device and the capability information about the another information processing device, the identification information and the capability information being connected to each other.

4. The information processing device according to claim 3, wherein the management information includes, as the capability information about the another information processing device, at least information about radio wave propagation measurement related to communication with the another information processing device and information about power consumption.

5. The information processing device according to claim 3, wherein the management information includes, as the capability information about the another information processing device, at least information about an output format for displaying the image information.

6. The information processing device according to claim 5, wherein

the information about the output format is information indicating that the image information is of main display or of sub display, and,

when the output format is of the sub display, the control unit sets the low power consumption mode in the another information processing device.

7. The information processing device according to claim 6, wherein, when switching between the main display and the sub display is performed, the another information processing device transmits information indicating timing of the switching to the information processing device.

8. The information processing device according to claim 2, wherein the control unit performs control to set a mode for the another information processing device to transmit the stream while sleeping at predetermined intervals, the mode being set as the low power consumption mode.

9. The information processing device according to claim 1, wherein the setting of a power consumption mode is performed with a predetermined RTSP message defined in the Wi-Fi Display specifications.

10. The information processing device according to claim 1, wherein the wireless communication unit performs exchange of the capability information through capability negotiation or capability re-negotiation defined in the Wi-Fi Display specifications.

11. The information processing device according to claim 1, wherein the capability information is exchanged in a RTSP M3 Message in capability negotiation or capability re-negotiation.

12. The information processing device according to claim 1, wherein

the wireless communication unit is a wireless communication unit configured to perform communication using a first frequency band, and communication using a second frequency band, the second frequency band having a higher data transmission rate than the first frequency band, and

the control unit sets a first power consumption mode for the first frequency band and a second power consumption mode for the second frequency band independently of each other.

13. The information processing device according to claim 2, wherein, when the management information is changed, the control unit performs control to transmit a command to the another information processing device, the command being for notifying the another information processing device of the change.

14. The information processing device according to claim 13, wherein the control unit performs control to transmit a RTSPM5 Message as the command to the another information processing device, the RTSPM5 Message containing wfd-triggered-method defined in the Wi-Fi CERTIFIED Miracast specifications.

15. An information processing device receiving a stream from another information processing device through wireless communication, the stream being for outputting image information,

the information processing device performing control to set a power consumption mode in the another information processing device based on an output format of an output unit, the output unit outputting the image information based on the stream.

16. An information processing device transmitting a stream to another information processing device through wireless communication, the stream being for outputting image information,

the information processing device comprising:

a wireless communication unit configured to perform communication with the another information processing device, the communication being for exchanging capability information about the information processing device and capability information about the another information processing device; and

a control unit configured to set a power consumption mode under the control of the another information processing device based on the capability information about the information processing device.

17. An information processing method for receiving a stream from another information processing device through wireless communication, the stream being for outputting image information,

the information processing method comprising:

a wireless communication step of performing communication with the another information processing device, the communication being for exchanging capability information about the information processing device and capability information about the another information processing device; and

a control step of performing control to set a power consumption mode in the another information processing device based on the capability information about the another information processing device.
