Solution Overview

Problem

Conventional teleconference systems face network load issues due to the transmission of unnecessary image and display data, which can hinder smooth conference proceedings, especially in environments with multiple participants.

Innovation Solution

A relay device equipped with a receiving unit for layout information, a changing unit for managing data transmission, and a control unit to adjust the transmission of display and image data based on notified layout changes, allowing for optimized data distribution and reduced network load.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If all image data and display data are transmitted to all communication terminals, then complete information availability is achieved, but network load increases excessively

Engineering Contradiction:
Improveinformation availabilityVSAvoidnetwork load
Core Design Contradiction:
Loss of informationVSQuantity of substance

Solution Approach 1:

The patent applies local quality by transmitting different types of data (image data and display data) to different communication terminals based on their specific needs and screen layout configurations. Each terminal receives only the data types relevant to its display areas, rather than all data types being sent to all terminals, thereby reducing overall network load while maintaining necessary information availability.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent segments data transmission by dividing it into different data types (image data and display data) and routing them selectively to different terminals. The relay device separates the transmission streams based on layout information, sending image data to terminals with image display areas and display data to terminals with document display areas, thus avoiding redundant transmissions.

Inventive Principle:
Principle #1Segmentation

2Productivity

If unnecessary data is transmitted to reduce network load, then network efficiency improves, but information completeness deteriorates

Engineering Contradiction:
Improvenetwork efficiencyVSAvoidinformation completeness
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent implements feedback by having communication terminals transmit their screen layout information to the relay device. The relay device uses this feedback to determine which data types should be transmitted to which terminals. This feedback mechanism ensures that only necessary data is transmitted, maintaining information completeness for each terminal's specific display needs while optimizing network efficiency.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent applies dynamics by making data transmission adaptive and changeable based on terminal requirements. The relay device dynamically adjusts which data types are transmitted to which terminals according to their layout information, allowing the system to optimize network efficiency for each specific configuration while ensuring each terminal receives complete information for its display areas.

Inventive Principle:
Principle #15Dynamics

3Quantity of substance

If data transmission is optimized based on layout information, then network load is reduced, but system complexity increases

Engineering Contradiction:
Improvenetwork loadVSAvoidsystem complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary (the relay device) that handles the complexity of selective data transmission. Rather than having each communication terminal independently determine what data to receive, the relay device acts as a mediator that receives layout information from all terminals, processes this information, and makes the transmission decisions. This centralizes the complexity in one component while keeping the terminals relatively simple.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A relay device for relaying data transmitted and received between communication terminals includes a receiving unit configured to receive a notice of changed layout information from a communication terminal that displays at least one of image data of a captured image and display data of a document in at least one area of a screen based on layout information, the image data and the display data being contained in the data transmitted and received between the communication terminals; a changing unit configured to change management information for managing transmission of the data to the communication terminal according to the notified layout information; and a control unit configured to control transmission of at least one of the display data and the image data to the communication terminal according to the changed management information.
