Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote conference systems face display distortion and operational menu visibility issues due to varying resolution settings between analog and digital terminals, lacking versatility and proper handling of aspect ratios, leading to user confusion and increased support inquiries.
Innovation Solution
An information terminal with a resolution determination unit to assess connected display device capabilities, a resolution selection unit to choose appropriate resolutions, and a resolution change unit to adjust the display accordingly, ensuring proper display of image data and auxiliary information across different devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed resolution value (e.g., 1280×720) is used for image data transmission, then the transmission terminal can maintain a standard aspect ratio (16:9), but display distortion occurs when connected to display apparatuses with different resolutions or aspect ratios
Solution Approach 1:
The transmission terminal dynamically determines the resolution of the connected display apparatus and adjusts the image data resolution accordingly. Instead of using a fixed resolution, the system changes the resolution based on the detected display capabilities, thereby preventing display distortion while maintaining compatibility with various display devices
Solution Approach 2:
The system changes the resolution parameter of the image data based on the detected display apparatus characteristics. By obtaining displayable resolutions from the display apparatus and selecting an appropriate resolution, the system adapts the image data to match the display device, eliminating display distortion across different aspect ratios
2Device complexity
If image data is displayed on the display apparatus with the original resolution, then the transmission process is simple, but parts of the image or auxiliary information may not be displayed when the resolution exceeds the display apparatus capabilities
Solution Approach 1:
The transmission terminal performs preliminary detection of the display apparatus's resolution capabilities before transmitting image data. By obtaining the displayable resolutions in advance and determining the appropriate resolution, the system ensures that the image data is properly formatted to fit the display apparatus, preventing any part of the image or auxiliary information from being cut off
Solution Approach 2:
The system uses feedback from the display apparatus regarding its displayable resolutions to adjust the image data resolution. The transmission terminal receives information about the display capabilities and uses this feedback to select an appropriate resolution that ensures complete display of both the image and auxiliary information
3Reliability
If different resolution settings are used for analog and digital terminals, then each terminal type can be optimized, but user confusion increases when switching between terminal types
Solution Approach 1:
The transmission terminal is designed to universally support both analog and digital display terminals by automatically detecting the display apparatus type and resolution capabilities. The system performs resolution determination and image data adjustment based on the detected terminal, providing optimized performance for each terminal type while maintaining a consistent user experience across different connection types
Data Source
AI summary
An information terminal determines whether displayable resolutions of a display apparatus include a resolution of an aspect ratio other than a standard aspect ratio used for image data transmission in the case where apparatus information obtained from the display apparatus matches predetermined apparatus information, according to a determination result, selects a first resolution of an aspect ratio other than the standard aspect ratio or a second resolution of the standard aspect ratio, changes a resolution of the display apparatus to the selected resolution in the case where the apparatus information matches the predetermined apparatus information, and changes a resolution of the display apparatus to a recommended resolution of the display apparatus in the case where the apparatus information does not match the predetermined apparatus information.
