Abstract: A method and an apparatus for processing a high dynamic range (HDR) video including a subtitle, where the method includes: encapsulating HDR video data into a video data frame that matches a transmission interface; encapsulating subtitle information into a subtitle information frame that matches the transmission interface; and separately transmitting the video data frame and the subtitle information frame to a display device through the transmission interface, where the video data frame and the subtitle information frame are packets in two types of formats. According to the method provided in this application, content and subtitle information of a dynamic metadata HDR video are separately transmitted to the display device. In this way, the display device can obtain the separated video content and subtitle information, and then separately perform corresponding processing on the HDR video and a subtitle.

Abstract: A video signal processing method includes obtaining a first linear luminance signal based on a first linear red green blue (RGB) signal corresponding to a video signal, converting the first linear luminance signal into a first non-linear luminance signal, performing a piecewise luminance mapping on the first non-linear luminance signal to obtain a second non-linear luminance signal, converting the second non-linear luminance signal into a second linear luminance signal, calculating a luminance gain between the second linear luminance signal and the first linear luminance signal, and obtaining, based on a product of the luminance gain and the first linear RGB signal, an RGB display signal corresponding to the video signal.

Abstract: A display method, system and device relating to the field of image processing technologies are provided for audience who can obtain global information on a sports field, so as to help determine a game situation in a timely manner and enhance a sense of participation, thereby providing better visual experience for the audience and improving viewing effect. In addition, the method can provide more information that the audience is interested in. In the method, a display side device receives first data from a capturing side device, and displays a first interface based on the first data, wherein the first interface includes a preset layer and a radar map superimposed on a specified area of the preset layer, the preset layer is obtained based on a preset viewpoint image of a target scene, and the radar map indicates location information of a plurality of target objects in the target scene.
