Cockpit Display Window Calibration for Uncertified Video Streams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for displaying open-world applications on aircraft cockpit screens face challenges in adapting uncertified video streams to the cockpit's dimensions and resolution, leading to suboptimal display and interaction, particularly with the presence of black bands due to mismatched aspect ratios and limited space, which complicates human-machine interactions.
Innovation Solution
A method that processes data streams from uncertified video sources by allowing pilots to manually select and calibrate a window of interest on the cockpit display screen, enabling the avionics platform to crop and resize the stream accordingly, ensuring optimal display and interaction without requiring software updates, and maintaining compliance with certified interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the uncertified video source delivers data stream with its own aspect ratio (e.g., 16:9), then the video content can be displayed, but black bands appear due to mismatch with the cockpit display screen dimensions
Solution Approach 1:
The system dynamically switches between two operational modes: automatic mode where the entire video stream is displayed with aspect ratio adaptation (including black bands), and calibration mode where the pilot manually defines a window of interest that is then cropped and displayed without black bands. This dynamic switching resolves the contradiction by allowing the system to adapt to different display requirements.
Solution Approach 2:
The video stream is segmented into a window of interest that the pilot manually selects and calibrates. This segmentation allows the system to focus on and optimize the display of the most relevant portion of the video content, eliminating the need to display the entire stream with its original aspect ratio constraints.
2Area of stationary object
If the entire data stream is displayed to maintain aspect ratio, then no black bands appear, but the display area is not fully utilized and interaction precision is reduced
Solution Approach 1:
Instead of uniformly displaying the entire video stream, the system applies local quality enhancement by cropping to a window of interest that the pilot manually calibrates. This window is then displayed at full resolution and optimal aspect ratio, providing both maximum display area utilization and enhanced interaction precision for the most relevant video content.
3Manufacturing precision
If manual calibration of window of interest is implemented, then display optimization is achieved, but additional操作步骤 are required from the pilot
Solution Approach 1:
The system performs preliminary actions by providing the pilot with visual feedback during calibration mode, showing the window of interest overlay on the video stream. This allows the pilot to accurately and quickly calibrate the window position and size before final display, reducing the time required for optimal setup.
Data Source
AI summary
A method for processing a data stream from an uncertified video source, the data stream being intended to be displayed at least partially on a display screen of a cockpit of an aircraft, the display screen having predetermined dimensions and a predetermined resolution. The processing method comprises a calibration mode comprising a step wherein a window of interest is selected on the display screen of the cockpit by the pilot. The processing method further comprises a step wherein a portion of the data stream corresponding to the selected window of interest is displayed on the display screen.
