Solution Overview

Problem

Videoconferencing systems face challenges in maintaining image aspect ratios across different communication terminals, leading to potential distortion when images with varying aspect ratios are transmitted and displayed, as terminals may only process specific aspect ratios.

Innovation Solution

A communication management system that determines the aspect ratio of display areas on each terminal and generates control information to combine images with different aspect ratios, ensuring they are displayed without distortion by adjusting the layout to match the terminal's capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If images are converted to match a communication terminal's aspect ratio for display, then the image can be displayed on the terminal, but image distortion occurs

Engineering Contradiction:

Improveimage display compatibilityVSAvoidimage aspect ratio accuracy

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The display area is divided into multiple regions, each optimized for different aspect ratios. The system segments the display into a first display area for the first aspect ratio and a second display area for the second aspect ratio, allowing each image to be displayed in its native aspect ratio without distortion while maintaining compatibility with terminals having different aspect ratio requirements

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system transitions from a single-dimensional aspect ratio conversion approach to a two-dimensional display area allocation approach. By considering both the aspect ratio and the available display area dimensions, the system can allocate different portions of the display screen to different images based on their respective aspect ratios, preventing distortion while ensuring display compatibility

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Device complexity

If a single display area is used for all images, then the display layout is simple, but images with different aspect ratios cannot be displayed without distortion

Engineering Contradiction:

Improvedisplay layout complexityVSAvoidmulti-aspect ratio support

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The display system is designed to handle multiple aspect ratios within a single unified display area. By implementing logic that automatically detects and allocates appropriate display regions based on image aspect ratios, the system achieves multi-functionality - it can display images with different aspect ratios (16:9, 4:3, etc.) without requiring separate display hardware or complex manual configuration, thus supporting universal compatibility while maintaining relatively simple overall structure

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A communication management system receives, from a first communication terminal, size information indicating a size of one or more display areas to be displayed on a screen of a first display provided for the first communication terminal, determines an aspect ratio of a first display area based on the first aspect ratio of the first image and a size of the first display area, generates control information instructing to add the second image having the second aspect ratio to the first display area having the determined aspect ratio, and transmits the control information to the relay device.
