Abstract: A mobile device, a controlling method thereof, an image display apparatus, and a controlling method thereof are provided. The mobile device includes: a user interface (UI) configured to receive a user command to control the image display apparatus; a communication interface configured to provide a service according to the user command through an access point (AP) to which the image display apparatus is connected, and perform a direct connection operation with the image display apparatus in response to the service being provided; and a controller configured to control the communication interface to hand the service over to a direct channel connected to the image display apparatus in response to the direct connection operation being completed.

Abstract: A method for setting a communication channel of a first device is provided. The method for setting the communication channel of the first device includes: communicating with an Access Point (AP) via a predetermined channel; and in response to a problem arising in communicating with the AP, alternating between an AP search mode to discover the AP and a standby mode to set the communication channel for communicating with a second device among a plurality of channels.

Abstract: A device and method for transmitting/receiving video data is disclosed. A sink device configured to receive video data from a source device includes communication circuitry configured to communicate with the source device; and a controller configured to transmit a probe request frame for detecting the source device, to receive a probe response frame from the source device receiving the probe request frame via the communication circuitry, and to obtain information regarding at least one external input source of the source device from the probe response frame.

Abstract: A display apparatus which is controlled by a remote control apparatus is provided. The display apparatus includes a wireless fidelity (Wi-Fi) module which is connected to an access point (AP) and operates in a Wi-Fi station mode and a controller which controls the Wi-Fi module to interrupt the connection to the AP when a Wi-Fi peer-to-peer (P2P) function is executed and iterates an operation of resuming the connection to the AP after a search operation is performed through each channel while a plurality of channels are sequentially selected. when an external device which performs P2P communication is found in the search operation, the controller controls the Wi-Fi module to perform a listen operation of receiving a signal transmitted from the external device and transmitting a response.

Abstract: An electronic apparatus including: a communicator configured to wirelessly connect to an access point (AP) to enable wireless communication; a storage configured to store AP connection information for connection to the AP through the communicator; a reader configured to read a direct connection information code from an external device when the direct connection information code for direct wireless connection by the electronic apparatus to the external device is installed on the external device; and a controller configured to establish a direct wireless connection to the external device based on the direct connection information code read by the reader and transmit the AP connection information stored in the storage to the external device which is directly wirelessly connected so the external device connects to the AP based on the AP connection information.

Abstract: A wireless fidelity (Wi-Fi) device and Wi-Fi peer-to-peer (P2P) method of communication which minimizes degradation of performance of a Wi-Fi Station mode operation is provided. A terminal device includes a wireless fidelity (Wi-Fi) module which is connected to an access point (AP) and operates in a Wi-Fi station mode. A controller controls the Wi-Fi module to interrupt the connection to the AP when a Wi-Fi peer-to-peer (P2P) function is executed, and iterates an operation of resuming the connection to the AP after a search operation is performed through each channel while a plurality of channels are sequentially selected. When an external device to perform P2P communication is found in the search operation, the controller controls the Wi-Fi module to perform a listen operation of receiving a signal transmitted from the external device and transmitting a response.
