Abstract: The disclosure provides a display apparatus, and the display apparatus at least includes a display and a controller. At an initial state, the display presents a homepage; in response to a startup instruction, the display jumps to a search interface from the homepage; the search interface has a user interface, and the user interface is configured to receive a search content input from a user; in response to a search instruction, the controller reads the search content; and if the search content includes a phrase for locating, the controller controls an application corresponding to the phrase for locating to be started so as to transmit the search content to the application to cause the application to send a request carrying the search content to a server of the application.

Abstract: The present application discloses a page loading method and a display apparatus. While launching an application, a URL of the application, a code package, and a URL of a loading page are obtained; when the URL of the application is a target protocol URL, a loading parameter is read from the code package; the loading parameter is written into the URL of the loading page to generate a new URL of the loading page; and based on the new URL of the loading page, a loading page including display content corresponding to the loading parameter is presented on a display.

Abstract: Disclosed is a viewport display method and display apparatus. The method includes: receiving a user operation for continuously moving out of a viewport by causing a selector position on a boundary element of the viewport; determining first element numbers that correspond to elements in a virtual list in which the boundary element is located according to the user operation; determining second element numbers that correspond to to-be-displayed elements on the virtual list according to the first element numbers and the direction of the selector moving out of the viewport; sorting the second element numbers; updating a virtual list rendered by the elements that correspond to the first element numbers by utilizing the sorted second element numbers; and controlling total elements in the updated virtual list to be displayed in the viewport.

Abstract: The present application provides a display device, comprising: a display; a user interface; and a controller, configured to: control the display to display a user interface in response to user input for indicating displaying a plurality of items, the user interface comprising a plurality of items, the plurality of items being arranged in an equal-width and unequal-height mode, and the user interface further comprising a selector for indicating that a item is selected.

Abstract: The embodiments of the present disclosure provide a display apparatus and a signal transmission method for the display apparatus. The display apparatus can use a voice assistant application to send received user voice to a voice assistant server, so that the voice assistant server can parse the user voice to obtain a channel switch instruction. In response to the channel switch instruction sent from the voice assistant server, the display apparatus receives an audio and video signal transmitted by a channel corresponding to the channel switch instruction, and plays the audio and video signal.

Abstract: Embodiments of the present application disclose a method for audio and video processing and an electronic device. A first decoding result corresponding to main channel audio and a second decoding result corresponding to audio description are acquired according to audio data in an audio and video file; and the first decoding result as well as an audio mixed result of the first decoding result and the second decoding result are output respectively through different audio output devices, so that in a scenario where a normal user and a visually impaired user watch audio and video at the same time, the normal user and the visually impaired user can select different audio output devices for audio listening to ensure that the two do not affect each other, which satisfies the needs of the normal user and the visually impaired user to watch at the same time.
