There is provided an information processing device including an operation acceptance unit configured to accept a user operation related to an image based on image data received from another information processing device using short-range wireless communication when the image is displayed on a display unit, and a controller configured to perform control in a manner that notification information for issuing a notification that the user operation is accepted is output when the user operation is accepted, and control data corresponding to the user operation is transmitted to the other information processing device.

Information processing device, communication system, and information processing method

There is provided a wireless communication apparatus and wireless communication method, which can perform information transfer, while suppressing interference to other terminal stations, and preventing a reduction of a transmission opportunity of other terminal stations. By causing the transmission power to be reduced, at the time when a traffic amount to be transmitted and received by itself increases, a terminal station which performs wireless access based on CSMA on a mesh network can suppress interference to other surrounding terminal stations, and can prevent a reduction of a transmission opportunity of other terminal stations. By measuring the number of and sizes of packets to be transmitted and received, it is possible for a terminal station to comprehend the traffic amount to be transmitted and received by itself, and perform a control of the transmission power by this.

Wireless communication apparatus and wireless communication method

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.

Information processing for recognition of acceptance of user operation

A terminal search unit searches for a predetermined transmitter terminal. A determination unit determines whether to participate in relay transfer involved in data transmission from the predetermined transmitter terminal found by the terminal search unit to a predetermined receiver terminal, using information possessed by the terminal device. A notification unit notifies the predetermined transmitter terminal of participation when the determination unit determines that the terminal device participates. It is possible to satisfactorily participate in relay transfer involved in data transmission from the predetermined transmitter terminal.

Terminal device, method for allowing terminal device to participate in relay transfer, and method for inviting terminal device to relay transfer

Efficient data transfer over a public network is achieved. A terminal searching unit searches for a neighboring terminal device. A display unit displays a list of terminal devices discovered by the terminal searching unit. A terminal selecting unit selects a predetermined terminal device included in the list based on the list displayed on the display unit. A data transmission unit transmits data using the predetermined terminal device selected by the terminal selecting unit as a relay. The list of neighboring terminal devices discovered by the search is displayed and a predetermined terminal device is selected using the list and is used for relay transfer, which allows the user to easily select a predetermined terminal device to be used for the relay transfer.
