Priority-Based Image Routing for Conference Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic conference systems, when the number of screens on the transmitting side differs from the number of screens on the receiving side, it becomes impossible to simultaneously display all image information items, leading to confusion for presenters who must select which image information to display, especially when multiple conference rooms are involved.
Innovation Solution
A conference terminal apparatus that includes a screen control part to display multiple image information items, a priority allocation part to assign priority for display on remote screens, and an information transmission processing part to transmit image information and priority to remote terminals, allowing remote terminals to select based on priority criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the presenter selects image information items while performing presentation, then the intended information can be displayed, but the presenter becomes confused especially when multiple image information items must be selected
Solution Approach 1:
The system performs preliminary action by automatically selecting and prioritizing image information items before the presenter needs to display them. The priority allocation part pre-establishes the selection criteria and automatically determines which images to display, eliminating the need for the presenter to make selection decisions during the presentation.
Solution Approach 2:
The system serves itself by using the presenter's own presentation status as the selection criterion. The automatic selection part detects which image information items the presenter is referring to based on the presentation state, and automatically prioritizes those items for display, making the system self-adaptive to the presenter's needs.
2Loss of information
If all image information items are transmitted to remote conference rooms, then complete information is provided, but remote terminals cannot display all items when screen counts differ
Solution Approach 1:
The system extracts only the necessary image information items for transmission by using automatic selection to identify and prioritize relevant images. Instead of transmitting all image information items to all remote terminals, the system extracts and transmits only those with high priority based on the presenter's current presentation focus, adapting to different screen configurations.
Solution Approach 2:
The system applies local quality by providing different sets of image information items to different remote conference rooms based on their specific screen configurations and needs. Each remote terminal receives a customized subset of prioritized images that matches its display capabilities, rather than a uniform set for all terminals.
3Ease of manufacture
If the number of screens on transmitting side equals the number of screens on receiving side, then direct allocation is possible, but the system lacks adaptability when screen counts differ
Solution Approach 1:
The system changes the parameter of image selection from fixed one-to-one allocation to dynamic priority-based selection. By introducing priority levels and using automatic selection algorithms, the system can adapt to varying screen counts at different terminals, transforming the rigid allocation approach into a flexible parameter-driven distribution system.

AI summary
A conference terminal apparatus is used by a speaker of an electronic conference for transmitting image information displayed on a screen and causing a remote conference terminal apparatus used by an audience to display the image information on a remote screen. In the conference terminal apparatus, a screen control part displays a plurality of image information items on the screen. A priority allocation part allocates to each of the displayed image information items priority for being displayed on the remote screen. An information transmission processing part transmits to the remote conference terminal apparatus the displayed image information items and the priority allocated to each of the image information items.
