Drive Control System Separating Video and OSD Data Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies face challenges in processing high-resolution video signals and On-Screen Display (OSD) data, leading to poor image quality and reduced user experience due to mixed processing of video and OSD data, and the inability of single System on Chips (SOCs) to handle high resolutions like 8K, which complicates control mechanisms and increases load.
Innovation Solution
A drive control system comprising a System on Chip, a video data processor, an OSD data processor, and a display drive circuit that processes video and OSD data separately before fusion for display, with the System on Chip managing data architectures and user instructions to optimize display settings and handle multiple SOCs for high-resolution decoding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If video data and OSD data are processed separately through different processors, then display image quality is improved, but device complexity increases
Solution Approach 1:
The patent divides the processing system into two independent processors: a video data processor for processing video data and an OSD data processor for processing OSD data. This segmentation allows each processor to be optimized for its specific function, improving overall processing quality while managing complexity through functional separation.
Solution Approach 2:
The patent combines the separately processed video data and OSD data through a data fusion module to generate the final display output. This merging step integrates the benefits of separate processing while producing a unified high-quality display image, resolving the contradiction between quality improvement and complexity increase.
2Device complexity
If a single SOC processes high-resolution video signals, then device complexity is reduced, but processing capability becomes insufficient for 8K resolution
Solution Approach 1:
The patent segments the processing tasks by separating video data processing and OSD data processing into different processors. This allows the system to handle high-resolution signals like 8K by distributing the processing load, achieving the necessary processing capability without requiring a single overly complex SOC.
Solution Approach 2:
The patent designs the video data processor and OSD data processor as independent functional units that can handle various resolutions including 8K. This multi-functional design allows the system to adapt to different resolution requirements while maintaining manageable device complexity through modular architecture.
3Device complexity
If video data and OSD data are mixed during processing, then device complexity is reduced, but image quality deteriorates
Solution Approach 1:
The patent implements separate processing paths for video data and OSD data through dedicated processors, preventing mixed processing that would degrade image quality. This segmentation ensures that each data type receives appropriate processing optimization while maintaining clear boundaries between processing streams.
Solution Approach 2:
The patent introduces a data fusion module as an intermediary that receives separately processed video data and OSD data, combines them appropriately, and outputs the final display signal. This intermediary component enables quality preservation through separate processing while achieving the ultimate goal of integrated display output.
