Device and method for processing video content for display control

Various aspects of a video processing device and method for display control includes detection, from a sequence of image frames received from a video source, a transition from one or more frames associated with a first metadata to one or more other frames associated with a second metadata. First visual properties of the one or more frames are determined based on the first metadata. Second visual properties of the one or more other frames are determined based on the second metadata. The determined second visual properties of the one or more other frames are controlled in accordance with the determined first visual properties of the one or more frames to enable a smooth transition.

METHOD AND SYSTEM FOR AUTOMATIC REAL-TIME FRAME SEGMENTATION OF HIGH RESOLUTION VIDEO STREAMS INTO CONSTITUENT FEATURES AND MODIFICATIONS OF FEATURES IN EACH FRAME TO SIMULTANEOUSLY CREATE MULTIPLE DIFFERENT LINEAR VIEWS FROM SAME VIDEO SOURCE
20210258621 · 2021-08-19 ·

A method, a programmed computer system, for example, a network-based hardware device, and a machine readable medium containing a software program for modifying a high definition video data stream in real time, with no visible delays, to add content on a frame by frame basis, thus simultaneously compositing multiple different customized linear views, for purposes such as creating and broadcasting targeted advertising in real time. The method employs conventional video processing technology in novel and inventive ways to achieve the desired objective by passing data selected by the program back and forth between a GPU and a CPU of a computer. The method is also usable with data streams having lower than high definition where real time processing is desired and yields better results than conventional methods. In such applications, all processing may be done by the CPU of a sufficiently powerful general-purpose computer.

Display method and display device

Provided is a display method of displaying, on a display device, video of video data where luminance of video is defined by a first EOTF corresponding to HDR. The method includes: acquiring the video data; performing first conversion where the luminance of the video is converted to a luminance corresponding to a dynamic range of a third EOTF, where, with regard to a second EOTF that is part of the first EOTF and is the part of a luminance range where the peak luminance indicated by the peak luminance information included in the acquired video data is maximum luminance, the dynamic range of luminance of the second EOTF is reduced with maximum luminance of the second EOTF matching displayable luminance of the display device, while maintaining the relative relationship of luminance of the second EOTF; and displaying the video on the display device using the result of the first conversion.
