Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current videoconference systems face challenges in managing content data transmission, as they often require high image and sound quality across all terminals, which can lead to inefficient use of communication bandwidth and increased costs, especially when not all applications necessitate such high quality.
Innovation Solution
A transmission management apparatus and system that dynamically manage sessions by establishing multiple quality levels of image and sound data transmission (low, intermediate, and high resolution) based on bandwidth availability and specific application needs, using a relay apparatus to optimize data transfer between terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high image quality and high sound quality settings are applied to all transmission terminals, then communication productivity and detection of communication partner circumstances are improved, but communication band is narrowed and transmission costs increase
Solution Approach 1:
The patent applies local quality by setting different image quality levels (high, intermediate, low) and different sound quality levels (high, intermediate, low) for different transmission terminals based on their specific application requirements. Instead of uniformly applying high quality to all terminals, the system selectively assigns quality levels to match each terminal's needs, thereby improving communication productivity for terminals that require it while conserving communication band for terminals that do not.
Solution Approach 2:
The patent implements dynamics by allowing the image quality and sound quality settings to be dynamically adjusted based on the type of application being used at each transmission terminal. The system can change quality levels in response to changing application requirements, enabling flexible adaptation between high productivity modes and bandwidth conservation modes as needed.
2Manufacturing precision
If high image quality settings are applied to all transmission terminals, then image data transmission quality is improved, but communication band is narrowed and transmission costs increase
Solution Approach 1:
The patent applies local quality by assigning different image quality levels (high, intermediate, low) to different transmission terminals based on their specific application requirements. For example, terminals used for applications requiring detailed visual information receive high image quality settings, while terminals used for applications where visual detail is less critical receive intermediate or low settings, thereby optimizing the use of communication band.
3Manufacturing precision
If high sound quality settings are applied to all transmission terminals, then sound data transmission quality is improved, but communication band is narrowed and transmission costs increase
Solution Approach 1:
The patent applies local quality by assigning different sound quality levels (high, intermediate, low) to different transmission terminals based on their specific application requirements. Terminals used for applications where audio quality is critical receive high sound quality settings, while terminals used for applications where audio quality is less important receive intermediate or low settings, thereby optimizing communication band utilization.
4Reliability
If high image quality and high sound quality settings are applied to all transmission terminals, then transmission reliability is improved, but transmission costs increase
Solution Approach 1:
The patent applies local quality by assigning different quality levels to different transmission terminals based on their specific application requirements. This ensures that terminals requiring high transmission reliability for critical applications receive high image and sound quality settings, while terminals used for less critical applications receive lower quality settings, thereby reducing overall transmission costs while maintaining necessary reliability levels.
