The present disclosure relates to a broadcast receiving apparatus and an operating method thereof. The broadcast receiving apparatus according to an embodiment of the present disclosure includes a network interface unit configured to communicate with an external server through a network; a broadcast receiving unit configured to receive a broadcast signal; a storage unit configured to store a database containing information on at least one broadcasting service provider; and a controller, wherein the controller checks whether access to the network is possible through the network interface unit, checks, when the access to the network is possible, a status of an application, which is registered in an application server, that contains information on a broadcasting service provider, through the network interface unit, determines whether it is required to update at least some of information contained in the database, based on a result of checking the status of the application, receives, when the update is required, an application containing information required for the update from the application server, updates at least some of the information contained in the database, based on the received application, and receives the broadcast signal based on the information contained in the database through the broadcast receiving unit. Various other embodiments are possible.

Broadcast receiving apparatus and operating method thereof

The present disclosure provides a display device comprising an external device interface connected to an external device; an infrared sensor configured to detect an infrared control signal generated from a remote control device for the external device; and a processor is configured to: initialize an auto-off timer time to count an auto-off time, when a power of the display device is turned on, initialize the auto-off timer time when the infrared control signal generated from the remote control device for the external device is detected through the infrared sensor, and control the power to be turned off when the automatic off timer time reaches a preset un-used time.

Display device and power-off control method thereof

Disclosed are a signal transmitting method, a signal transmitting apparatus, and a system for transmitting and receiving a signal. The signal transmitting method comprises the steps of: discovering a companion device using a multicast mode; receiving and storing device type information from the discovered companion device; receiving an application uniform resource identifier (URI) and storing the application URI to correspond to the device type information; and identifying the device type information of the companion device selected by a user and transmitting to the selected companion device the application URI corresponding to the device type information.

Signal transmitting apparatus, signal transmitting method, and system for transmitting and receiving signal

A digital service signal apparatus is disclosed. The digital service signal apparatus includes a receiving module receiving signaling information having channel information for an application from the digital service signal, a generating module generating a request using the channel information, a sending module sending the generated request, a downloading module downloading the application, an executing module configured to execute the API related to the application and a registering module configured to register the specific key set according to the mode number.

Method and apparatus for processing digital service signal

The digital service signal processing apparatus according to one embodiment of the present invention, comprises: a generation module for generating a request for receiving signaling information of an application related to a program of a digital service signal using the channel information related to the program of the digital service signal; a control module for transmitting the generated request, receiving the signaling information of the application, and determining whether the application is stored using the received signaling information of the application; and a download module for downloading, if it is determined that the application is not stored, the application using the signaling information of the application.

An apparatus for a television includes storage areas for storing a key and authentication information, a communication unit to transmit and receive information from a server supplying protected content, and a controller to control output of the protected content from the server based on an authentication procedure. This procedure includes encrypting the stored authentication information with the key, transmitting the encrypted authentication information to the server, and then outputting the protected content received from the server for display after transmission of the encrypted authentication information if determined to be valid.
