The present technique relates to a file generation apparatus, a file generating method, a file reproduction apparatus, and a file reproducing method capable of enabling a user to enjoy an HDR image. HDR information designated by HDR designating information is acquired from a file storing a track of a stream including the HDR information which is configured with feature information representing features of luminance of an HDR (high dynamic range) image having a dynamic range higher than that of an STD (standard) image and conversion information representing a conversion rule of converting the one of the STD image and the HDR image into the other and a target track including the HDR designating information designating the HDR information which is to be applied to the target track of interest in the HDR information of the track. The present technique can be applied to the case of acquiring HDR information which is to be applied to an image of a subtitle or the like stored in, for example, an MP4 file.

A human-machine interface involves plural spatially-coherent visual presentation surfaces at least some of which are movable by a person. Plural windows or portholes into a virtual space, at least some of which are handheld and movable, are provided by using handheld and other display devices. Aspects of multi-dimensional spatiality of the moveable window (e.g., relative to another window) are determined and used to generate images. As one example, the moveable window can present a first person perspective “porthole” view into the virtual space, this porthole view changing based on aspects of the moveable window's spatiality in multi-dimensional space relative to a stationary window. A display can present an image of a virtual space, and an additional, moveable display can present an additional image of the same virtual space.

According to various embodiments of the present invention, a server may comprise: a communication circuit; and a processor electrically connected to the communication circuit, wherein the processor is configured to: receive image data of a first camera, selected as a main camera, among image data captured by multiple cameras through the communication circuit; transmit the received image data of the first camera to a real-time broadcast server through the communication circuit; and when a second camera among the multiple cameras satisfies a predesignated selection condition of a main camera, transmit image data of the second camera to the real-time broadcast server through the communication circuit. In addition, various other embodiments are possible.

The present invention provides a method and an apparatus for transceiving a broadcast signal for viewing environment adjustment. A method for transmitting a broadcast signal, in accordance with one embodiment of the present invention, comprises the steps of: encoding video data and signaling information including metadata regarding the production environment of the video data; generating a broadcast signal comprising the encoded video data and signaling information; and transmitting the generated broadcast signal.

An electronic device and an operating method thereof are disclosed according to embodiments. An electronic device according to an embodiment includes: a camera; a display; a communication interface; a memory for storing one or more instructions; and a processor that executes the one or more instructions stored in the memory, the processor being configured to: generate an event instructing to display one or more markers on a screen of a display device and transmit the event to the display device; control the camera to capture an image of at least a portion of a wall around the display device using the one or more markers displayed on the screen of the display device according to the generated event; generate a background image to be displayed on the screen of the display device based on the obtained image; and transmit the generated background image to the display device such that the generated background image is displayed on the screen of the display device.

Provided are an artificial intelligence (AI) system that mimics cognitive functions, such as cognition and judgment, of the human brain using a machine learning algorithm such as deep learning and applications thereof. More particularly, provided is a device including a memory storing least one program and a first video, a display, and at least one processor configured to display the first video on at least one portion of the display by executing the at least one program, wherein the at least one program includes instructions for: comparing an aspect ratio of the first video with an aspect ratio of an area in which the first video is to be displayed, generating a second video corresponding to the aspect ratio of the area by using the first video when the aspect ratio of the first video is different from the aspect ratio of the area, and displaying the second video in the area, wherein the generating of the second video is performed by inputting at least one frame of the first video to an AI neural network.

A display apparatus is disclosed. The display apparatus includes an image processor configured to convert a frame rate of an image signal to a frame rate converted image signal, a display configured to display an image based on the frame rate converted image signal, and a controller configured to control the image processor to add an object to at least one of the image signal and the frame rate converted image signal depending on a characteristic of the object.

The present invention provides an intelligent TV control system and implementation method thereof, through a group of pressure sensors, pressure data and vital signs data of a plurality of body parts of user are collected; before being transmitted to terminal of intelligent TV, which then processes pressure data and vital signs data received from terminal of pressure sensors, and obtains sitting posture information and mental state information of user, before sending out a corresponding sitting posture adjustment advice or controlling to change play state of TV, based on sitting posture information and mental state information. The system and implementation method thereof, as described in present invention, by obtaining user state information, and controlling TV to adjust parameters automatically according to user state information, has improved an intelligence of intelligent TV, and provided convenience to users when using intelligent TV.

System, method, and computer product embodiments for controlling a display device's display settings from a computing device's touch-based user interface are described. In an embodiment, the computing device establishes a wireless connectivity with the display device. The computing device sends a command generated to query information related to the display setting. Then, the computing device receives the queried information from the display device. The computing device configures a graphical user interface (GUI) with the queried information to display configurations of the display settings on the touchscreen. The configurations include the display settings currently configured in the display device. The computing device further enables, within GUI, a displayed configuration from the display configurations to be calibrated by one or more touch gestures on the touchscreen.

Various embodiments for compensating for user view angle of a display device are presented. The viewing angle of a user may be determined using sensors. Based on the viewing angle, the attenuation of the output of the display device may be determined. Compensation mode for the display output may be determined. The compensation mode may adjust the output of the display to compensate for the display attenuation allowing an improved image quality at large viewing angles.
