Abstract: An aspect of the present invention proposes a method for performing partial refresh on display panels. According to one or more embodiments of the present invention, the display panels may be implemented as self-refreshing display panels communicatively coupled with a computing device that generates graphical data for display in the display panel. To perform partial refresh, consecutive frames are compared to identify the portions of the frames with updated material. In one or more embodiments, only the pixels corresponding to the updated portion(s) are refreshed in the display panel.

Abstract: Embodiments of the present disclosures provide a method, system and apparatus for transmitting intelligent information. When one frame of video data x is to be transmitted, a SDI sending terminal determines whether there is intelligent information satisfying a transmission condition; the transmission condition comprising that intelligent information is not transmitted and transmission of a frame of video data corresponding to the intelligent information is finished. If there is the intelligent information satisfying the transmission condition, the SDI sending terminal adds intelligent information y being one item of the intelligent information satisfying the transmission condition into a preset position of the video data x; and transmits the video data x having the intelligent information y. By using the solutions of the present disclosures, implementation costs are reduced and security is improved.

Abstract: Systems, apparatuses, and methods for synchronizing backlight adjustments to frame updates in a display pipeline. A change in the ambient light is detected and as a result, backlight settings are adjusted. To offset a reduction in the backlight, the color intensity in the frames is increased. While the change in ambient light is detected asynchronously, the adjustment to the backlight settings and color intensity is synchronized to a frame update via a virtual channel for the auxiliary channel of the display interface.

Abstract: Methods and systems for generating and applying scene-stable metadata for a video data stream are disclosed herein. A video data stream is divided or partitioned into scenes and a first set of metadata may be generated for a given scene of video data. The first set of metadata may be any known metadata as a desired function of video content (e.g., luminance). The first set of metadata may be generated on a frame-by-frame basis. In one example, scene-stable metadata may be generated that may be different from the first set of metadata for the scene. The scene-stable metadata may be generated by monitoring a desired feature with the scene and may be used to keep the desired feature within an acceptable range of values. This may help to avoid noticeable and possibly objectionably visual artifacts upon rendering the video data.
