Provided is a method for displaying application data in a wireless communication system, the method including transmitting, by a first device, audio and video data out of application data executed by the first device to a second device in a Wireless Fidelity (Wi-Fi) Display (WFD) session, if the WFD session is established through discovery between the first device and the second device, transmitting, by the first device, text or Graphic User Interface (GUI) data related to the transmitted audio and video data, to the second device in a session that is different from the WFD session, and receiving, by the first device, a close command for the application data and sending a message comprising a set parameter for stopping display of the text or GUI data to the second device.

Method and apparatus for displaying application data in wireless communication system

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method by which a master device provided by one embodiment of the present invention controls mirroring services between the master device and a slave device comprises the steps of: storing information related to first connection mode mirroring when a termination event of mirroring connected in a first connection mode has occurred; and setting mirroring in a second connection mode by using the stored mirroring-related information.

Method and device for controlling mirroring services

Provided is a method for playing multimedia contents in a first device of a communication system, the method including receiving a buffer storage capability of a second device from the second device, upon receiving a User Backward Seek (UIBC) command from the second device, determining a play position from which multimedia contents are to be played according to the UIBC command in a buffer of the second device based on the buffer storage capability of the second device, and notifying the second device of information about the determined play position.

Method and apparatus for playing multimedia contents in a communication

A method for providing contents in a communication system according to an embodiment of the present invention comprises the steps of: discovering multiple synchronization devices which will communicate with a source device and identifying device types of the discovered multiple synchronization devices; generating multiple contents for the multiple synchronization devices on the basis of the identified device types; and providing each of the generated multiple contents to a corresponding synchronization device, wherein each of the device types is determined according to at least one among the capacity, type, and function of the device.

Method and device for providing contents in communication system

A method of transmitting an inquiry message, performed by a display device, includes operations of reproducing content in the display device; receiving an input from a user, wherein the input from the user is related to the content; generating an inquiry message about the content, based on the input from the user; extracting information, which is related to the input from the user, from the content; and transmitting the extracted information and the inquiry message to an external device that is connected with the display device.

Method of transmitting inquiry message, display device for the method, method of sharing information, and mobile terminal

The present invention relates to an automatic switching method. A device according to an embodiment of the present invention is an automatic switching device in a second device, which comprises a controller for enabling the second device, together with a first device, to perform a terminal discovery and a service discovery, transmit a connection request message including a continuous connection field and an automatic connection mode from the second device, and receive a particular service from the first device on the basis of the information included in the connection request message, wherein the continuous connection field includes a service identifier.

Method and apparatus for automatic switching between devices

A portable device and a method for controlling a display device include receiving first display information of a first arrangement of icons displayed on a screen of the display device, displaying the first arrangement of icons on a display of a portable device based on the first display information, modifying the first arrangement of icons displayed on the display of the portable device to generate a second arrangement of icons, generating second display information based on the second arrangement of icons, and transmitting to the display device a request to display the second arrangement of icons on the display of the display device, the request comprising the second display information.

Method and system for controlling display device and computer-readable recording medium

A method of sharing content of a first device. The method includes performing authentication of a second device connected to the first device through a telephonic connection, receiving information from the second device about at least one third device connectable to the second device, based on a result of the performing of the authentication, accessing the at least one third device based on the received information and transmitting the content to the at least one third device based on the accessing.

Method and apparatus for sharing content

A contents streaming method of a user terminal device is provided. The method includes converting a certain portion of contents into a first format based on information to initially display contents on the external device, transmitting the certain portion of contents converted into the first format to the external device, converting the contents into a second format different from the first format after transmitting the portion of contents converted into the first format, and transmitting the contents converted into the second format to the external device.

User terminal device and contents streaming method using the same

A method for an information push service at a mobile station based on a wireless local area network (LAN) access point (AP). The method includes receiving a beacon message including a shortened Uniform Resource Locator (URL) from at least one AP, acquiring information based on the shortened URL included in the beacon message, and displaying the acquired information together with information included in the beacon message. The method allows a user to simply, conveniently, and easily acquire and make use of peripheral information of an area in which the user is located. The method also provides a service dependent on information on a position of contents, thereby being capable of allowing the user to easily access the contents.

Method, apparatus and system for information push service based on wireless LAN access point
