Onscreen Display Reference Point Rendering Independence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display systems face challenges in rendering customizable onscreen display reference points that are independent of video streams, particularly in managing resolution and transparency, while maintaining user-configurable options for position, color, and alpha values.
Innovation Solution
A system comprising a controller attached to a display that receives customizable characteristics, composes onscreen display reference points, and renders them independently of the video stream, using non-volatile memory for storage and adjusting resolution based on the video stream's resolution, with user-configurable options for position, color, and transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If onscreen display reference points are rendered as part of the video stream, then they can be displayed with the video content, but they cannot be independently customized for position, color, and transparency
Solution Approach 1:
The patent segments the display rendering into two independent components: video stream rendering and reference point rendering. The controller separately processes video frames and reference point graphics, allowing independent customization of reference point characteristics (position, color, transparency) without being constrained by video stream parameters. This segmentation enables the reference points to be overlaid on video content while maintaining full configurability.
2Ease of operation
If the controller renders reference points independently of video streams, then customization is enabled, but additional processing complexity is introduced
Solution Approach 1:
The patent introduces an intermediary layer in the controller that receives both video stream input and reference point configuration parameters, then combines them during the rendering process. This intermediary processing layer allows user-configurable options for reference points while maintaining a standardized interface for video output, managing the additional complexity through structured data flow and parameter separation.
3Adaptability or versatility
If resolution is adjusted based on video stream resolution, then display compatibility is improved, but reference point rendering becomes dependent on video parameters
Solution Approach 1:
The patent implements dynamic resolution adjustment where the controller detects the video stream resolution and automatically adapts reference point rendering parameters accordingly. The reference points maintain their independence through dynamic parameter adjustment rather than fixed dependency, allowing them to scale and position correctly across different video resolutions while preserving their customizable characteristics.

AI summary
In an example implementation according to aspects of the present disclosure, a method may receive a set of customizable characteristics corresponding to an onscreen display reference point. The onscreen display reference point may be composed based on the set of customizable characteristics. The onscreen display reference point may be stored in nonvolatile memory. The onscreen display reference point may be rendered on a display, wherein the rendering is independent of a video stream.
