Disclosed are a smart TV controlling method and a smart TV thereof, the method including: determining currently running UI; obtaining key controlling policy for the currently running UI according to pre-stored mapping between UI and key controlling policy, the key controlling policy indicating adjustment for UI controlling keys; generating controlling instruction according to received key information sent from remote controlling device and key controlling policy for the currently running UI; and sending the controlling instruction to the currently running UI for the UI to perform operation associated with the controlling instruction. The key information sent from the remote controlling device is adaptable to different UIs according to different key controlling policies of different UIs, allowing operations associated with key information be adapted to the requirements of different UIs, so that appropriate adjustments are made to the current running UI according to the user's needs.

An image display device includes: a processor; a memory configured to store channel information corresponding to at least one channel; and at least one program which is stored in the memory and executed by the processor. The program may include instructions for controlling a display so as to move a channel indicator in a first or second direction on a channel scroll bar and to display channel information of a channel corresponding to a point at which the channel indicator is located, in response to a first input of pressing a channel-up or channel-down key for a long time, and for switching a current channel to the channel corresponding to the point at which the channel indicator is located and displaying an image corresponding to the switched channel, in response to a second input of releasing the channel-up or channel-down key.

A method is provided for displaying an image based on a virtual reality (VR) apparatus. The method includes acquiring an image of raw-shooting-material and acquiring a shooting field-of-view (FOV) of the image of raw-shooting-material. The method also includes setting a scene FOV of a virtual scene of the VR apparatus according to the shooting FOV, and performing scene image generation and adaption to generate a scene image according to the image of raw-shooting-material and the scene FOV and to determine a size of the scene image according to the scene FOV. Further, the method includes determining a display area of the scene image by using a gyroscope sensor, and displaying the display area on a display screen of the VR apparatus.

A keyboard for use with a computing device includes multiple rows of keys with each of the rows of keys including multiple keys. A horizontal pitch of the keys is between 18 mm and 19 mm and a length of the rows of the keys is between 230 mm and 235 mm.

A TV audience survey system for determining the TV viewing activities of a plurality of individuals in a household includes a master device and multiple tags, each tag assigned to an individual. After an individual logs into the system and starts watching the TV, the master device communicates with the corresponding tag repeatedly to accumulate data representing the individual's TV viewing activities. Such data can be used to determine when the individual stops watching the TV for an extended period of time without logging out of the system and when the household member remains watching the TV after logging or being logged out of the system. The master device then reports the accumulated data to a remote server, which uses the data to determine whether the individual complies with the logging protocol defined by the TV audience survey system and update the TV viewership data associated with this household.

A method for rapidly searching information, a display control system and an input device, wherein the method comprises: receiving a first operating instruction (101) when an electronic device is in an operating state; displaying a first operating page on the electronic device according to the first operating instruction (102); receiving a second operating instruction, and opening an icon corresponding to a first parameter on the first operating page according to the second operating instruction to enter a first parameter selection page (103); and receiving a third operating instruction, and selecting an icon corresponding to a target parameter in first parameters on the first parameter selection page according to the third operating instruction (104). The method makes operations in the channel switching used in the existing electronics device simpler, brings convenience to the users, and improves the interaction capability between the users and the electronic device.

A remote control system and related method for controlling a video device are presented. The remote control system contains a plurality of buttons arranged in a grid pattern that correspond to user selectable options displayed on a display screen arranged in the same grid pattern. The user selects options on the screen by pressing the corresponding button on the remote control.

A display device including a display configured to display a received broadcast; a user input interface configured to receive a signal from a remote control device; and a controller configured to: when a function key setup mode entry signal is received from the remote control device, display a plurality of keys of the remote control device on the display, the plurality of keys respectively including images of numeric keys for inputting a desired number, display a mapped application icon on the image of a key to which an application is mapped among the plurality of keys, in response to a first preset input on the image of the key to which the application is mapped, input the desired number, and in response to a second preset input on the image of the key to which the application is mapped, stop the broadcast and execute the application.

A file recommendation method includes creating a two-dimensional matrix according to user identifications and file identifications included in a history playing record, wherein the user identifications are a first dimension of the two-dimensional matrix and the file identifications are a second dimension of the two-dimensional matrix. The method includes filling an element location corresponding to a relationship between the user identifications and the file identifications in the two-dimensional matrix with an element. The method includes decomposing the two-dimensional matrix to obtain a designated matrix, and dividing the designated matrix according to the first dimension to obtain a feature vector corresponding to each user identification. The method includes performing group division processing for each user identification according to the feature vector corresponding to the user identification to obtain at least one user group. The method includes recommending a file according to the at least one user group.

Methods and systems are described for determining a video resource allocation for outputting content via a display. The video resource allocation may be determined based on priorization data that priorities different areas of the content. A greater portion of resources for outputting the content may be allocated to different areas of the content based on the priorization of data.
