Abstract:
1. A first sink device for receiving one of video data or audio data from a source device and for reproducing signals corresponding thereto, said first sink device comprising: a device detecting unit detecting devices capable of establishing a wireless connection; a user input unit which enables a user to select the source device and a second sink device to be paired with the first sink device out of a plurality of devices detected by the device detecting unit, in which each of the devices from which the second sink device is selectable is directly connected to the selected source device; a message transmitting unit transmitting an autosetup request message to the selected source device; a message receiving unit receiving an autosetup response message from the source device to which the autosetup request message was transmitted; a pairing processing unit carrying out a pairing process with the selected second sink device to be paired with the first sink device; a wireless connection unit establishing a wireless connection with the selected source device; and a reproduction starting unit receiving data from the selected source device after establishment of the wireless connection and carrying out a reproduction process, in which the first sink device is directly connectable to the source device and the selected second sink device is directly connected to the selected source device, so as to enable the source device to provide the video or audio data directly to the first sink device and to provide the video or audio data directly to the second selected sink device, and in which the pairing process between the first sink device and the selected second sink device is enabled to be automatically performed after transmission of the autosetup request message to the selected source device by the first sink device which is the same sink as one of the paired sink devices such that the pairing process between the first sink device and the selected second sink device is performable by the user operating only the first sink device.
