A display device according to the present disclosure may include a display part; a wireless communication part configured to perform wireless communication with a first portable device connected to a first terminal displaying a first image or a second portable device connected to a second terminal displaying a second image; and a controller configured to: when a screen sharing request is received from the first portable device, determine whether a management mode for managing screen sharing of the second portable device connected to the second terminal is activated, when the management mode of the second portable device is activated, determine whether screen sharing permission has been received from the second portable device, when the screen sharing permission is received, receive the first image data corresponding to the first image from the portable device, and based on the received first image data, display first mirroring image on the display part.

Display device and screen sharing operation method thereof

A digital broadcasting system and a method for processing data in the same are disclosed. A method for controlling a digital television (DTV) located in one independent space among a plurality of independent spaces physically separated from one another is disclosed. The DTV includes an access point (AP) card. The method includes receiving emergency alert information and independent space identification (ID) information from a management server, comparing independent space ID information pre-stored in the DTV with the received independent space ID information, parsing the emergency alert information when the pre-stored independent space ID information is identical to the received independent space ID information, and switching an operation mode of the DTV from a power-off mode to a wake mode on the basis of the parsed emergency alert information, and displaying the emergency alert message.

Digital broadcasting system and method of processing data in digital broadcasting system

A digital broadcasting system and a method for processing data in the same are disclosed. A method for controlling a digital television (DTV) located in one independent space among a plurality of independent spaces physically separated from one another is disclosed. The method includes receiving guest information recorded in a storage area of a compact wireless device and a wired equivalent privacy (WEP) key value of the AP card, receiving the WEP key value corresponding to the AP card of the DTV from a management server, comparing the WEP key value received from the compact wireless device with the WEP key value received from the management server, generating at least one recommendation service information dependent on the guest information, if the two WEP key values are identical to each other, and displaying the generated recommendation service information.
