Content Processing Apparatus for Low Resolution Display Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High resolution content, such as UHD content, is difficult to display on low resolution display apparatuses as objects like subtitles and menus become reduced in size, making them hard to recognize and select for users.
Innovation Solution
A content processing apparatus that processes high resolution content to adapt objects according to the output resolution of the display panel, scaling down the video frame and adding objects specifically designed for low resolution to ensure they are easily identifiable and usable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If high resolution content is displayed on a low resolution display apparatus, then the content can be viewed on available devices, but the objects (subtitles, menus) become reduced in size and are difficult to recognize
Solution Approach 1:
The patent segments the content processing into two distinct parts: the video frame scaling and the object rendering. By separating the object (subtitle, menu) processing from the video frame processing, the system can apply different scaling rules to each. The video frame is scaled down to fit the low resolution display, while objects are rendered at appropriate sizes for the display resolution, preventing them from becoming too small to recognize.
Solution Approach 2:
The patent applies different quality characteristics to different parts of the display output. The video frame is scaled to match the display resolution, while objects are rendered with local quality adjustments that ensure they remain clearly visible and recognizable. This allows the subtitle and menu elements to maintain appropriate size and clarity even when the overall content is displayed on a low resolution apparatus.
2Area of stationary object
If the video frame is scaled down to fit low resolution display, then the content fits the screen, but the objects become proportionally smaller and harder to identify
Solution Approach 1:
The patent divides the display rendering into separate processing streams: one for the video frame and another for objects. This segmentation allows the video frame to be scaled down to fully utilize the low resolution display area, while objects are processed separately and rendered at sizes optimized for identification and interaction, rather than being proportionally reduced with the video frame.
Solution Approach 2:
The patent changes the rendering parameters for objects based on the display resolution. When detecting that the display apparatus has low resolution, the system adjusts object rendering parameters to ensure objects maintain appropriate size and visibility. This parameter adjustment allows objects to remain easily identifiable even when the video frame is scaled down to fit the display.
3Manufacturing precision
If objects are rendered at high resolution for UHD content, then they maintain quality on UHD displays, but they become too small to recognize on HD displays
Solution Approach 1:
The patent dynamically changes object rendering parameters based on the detected display resolution. When the display apparatus is identified as having low resolution (HD), the system adjusts object rendering parameters to produce larger, more visible objects. This parameter adaptation ensures that objects maintain appropriate visibility and recognizability on HD displays while preserving high rendering quality when displayed on UHD apparatus.
Solution Approach 2:
The patent implements dynamic object rendering that adapts to the display capabilities. The system detects the display resolution and dynamically adjusts object size and rendering characteristics accordingly. This dynamic adjustment allows objects to be rendered with appropriate precision for the specific display type, ensuring they remain recognizable on low resolution displays while maintaining high quality on UHD displays.
Data Source
AI summary
A content processing apparatus is provided. The content processing apparatus includes an input unit which receives high resolution content, a data processor which generates a video frame by processing the high resolution content, and a controller which, if an output resolution of a display panel, which is to display the video frame, is lower than the resolution of the high resolution content, controls the data processor to form an object corresponding to the high resolution content as an object for low resolution and add the object for low resolution to the video frame.
