A remote control device sends a patterned infrared signal to the display device. A display device receives the patterned infrared signal by using a plurality of infrared receivers. The display device obtains a projection pattern of the patterned infrared signal on a display screen. The display device determines a pointing position of the remote control device on the display screen based on the projection pattern. The display device displays a prompt mark in the pointing position of the display screen, where the prompt mark is used to prompt a user with the pointing position of the remote control device on the display screen.

An application control system and method is adapted for use with an entertainment system of a type including a display such as a monitor or TV and having display functions. A control device may be conveniently held by a user and employs an imager. The control system and method images the screen of the TV or other display to detect distinctive markers displayed on the screen. This information is transmitted to the entertainment system for control of an application or is used by the control device to control an application.

Example bullet screen play methods and apparatus are described. One example bullet screen play method includes receiving a bullet screen enabling instruction for a target video, where the bullet screen enabling instruction instructs to play a bullet screen in a virtual reality (VR) bullet screen manner. An annular transparent bullet screen layer is drawn in a preset orientation of a video layer of the target video in response to the bullet screen enabling instruction, where a first height of the video layer is less than a second height of the bullet screen layer. Bullet screen information of a real-time bullet screen of the target video is obtained. Three-dimensional coordinates of the real-time bullet screen on the bullet screen layer are calculated based on the bullet screen information. The real-time bullet screen is refreshed and played on the bullet screen layer based on the three-dimensional coordinates.

A system and method provide for installation and setup of a set-top box (STB) in a Digital TV network includes a mobile device running a mobile application, an operator application, and a display configured to display video from the STB. A status of the STB is determined and encoded into an optically scannable graphic displayed by the display. The optically scannable graphic is scanned with an optical device in communication with the mobile device and the status of the STB is decoded. The status of the STB is transmitted to the operator application compared with an acceptance criteria.

A user terminal apparatus is provided. The user terminal apparatus for performing a remote control function for an electronic apparatus includes a communication unit configured to communicate with an electronic apparatus for providing a text input user interface (UI), an input unit configured to receive a user command for input of a specific text on the text input UI, a fingerprint scanner provided in the input unit and configured to recognize a user fingerprint, and a controller configured to recognize a user fingerprint according to the user command and to transmit information corresponding to the recognized user fingerprint to the electronic apparatus in response to the electronic apparatus entering a preset text input mode.

A display device according to an embodiment of the present invention may comprise: a display unit for displaying a content image; a microphone for receiving voice commands from a user; a network interface unit for communicating with a natural language processing server and a search server; and a control unit for transmitting the received voice commands to the natural language processing server, receiving intention analysis result information indicating the user's intention corresponding to the voice commands from the natural language processing server, and performing a function of the display device according to the received intention analysis result information.

Provided is a display device including a display unit, a storage unit configured to store information on a web page, a microphone configured to receive a user's voice command, a network interface unit configured to perform communication with a natural language processing (NLP) server, and a controller configured to transmit text data of the voice command to the NLP server, to receive intention analysis result information corresponding to the voice command from the NLP server, to select, as a final candidate address, one of a plurality of candidate addresses related to a search word included in the received intention analysis result information if the search word is not stored in the storage unit, and to access a website corresponding to the selected final candidate address.

A smart device is provided with a main remote control application that may be configured using information obtained from a QR code. The main remote control application may present images of original remote controls corresponding to devices which are controllable by the configured main remote control application. In connection with a presented image of an original remote control, the display may present icons that are representative of a subset of the buttons of the original remote control. The user interface also allows a user to select amongst the images of the original remote controls to change which appliances are to be controlled via the user interface. A pop-up remote control widget may also be provided which may be invoked without switching to the main remote control application provisioned on the smart device.

An electronic device, method, and a non-transitory computer-readable recording medium provide a function of locating and identifying a paired device in a wireless network. The wireless network communicatively connects a plurality of electronic devices including the electronic device and the paired device. The electronic device includes a user interface, a network interface, a hardware processor, and a non-transitory memory storing one or more programs. The hardware processor executes the programs to receive a search command using a first communication connection via the network interface. Moreover, the hardware processor executes the programs to determine whether the peer device identifying information matches identifying information of the electronic device. When the peer device identifying information matches the identifying information of the electronic device, the electronic device identifies as the paired device. Otherwise, the electronic device broadcasts to the wireless network using a second communication connection.

A system that simplifies electronic communication and data sharing by integrating various apps into one. The COMTOOL communication system is characterized by a color coded user ID as a security feature for preventing imposters in a user's contacts to reduce fake news distribution. The system integrates a photo album, a calendar, a voice over IP, a video chart, a video playback, a religious and political group's app and a forum app into one interface and makes them available as a mobile application on a mobile phone, a web based application hosted on a server and as an application installed in television sets. A television remote control is designed to transmit data to a television lens for pausing, rewinding and forwarding a video in playback mode. Double pressing a selector button on a television remote control subscribes to a content provider channel.
