Method and apparatus for switching input character in WFD

A first wireless device for switching an input character, comprising:

• a communication unit for communication with a second wireless device;
• and
• a processor connected with the communication unit to be operable, wherein the processor is implemented to
• transmit a character switch capability parameter to a second wireless device through a User Input Back Channel (UIBC) capability negotiation process with the second wireless device, transmit a first character switch establishment parameter to the second wireless device through a UIBC establishment process so as to establish the first character outputted onto each screen of the first wireless device and the second wireless device,
• transmit a key code for a character switch button through a UIBC to the second wireless device through a user input device of the first wireless device, and
• transmit a second character switch establishment parameter to the second wireless device through a UIBC re-establishment process so as to switch, to the second character, the first character outputted onto each screen of the first wireless device and the second wireless device, wherein the first wireless device is a device for supporting streaming of multimedia contents, and
• wherein the second wireless device is a device for receiving and rendering the multimedia contents from the first wireless device through a peer-to-peer (P2P) link with the first wireless device.
