Solution Overview

Problem

Existing multi-party video call systems using a multipoint control unit (MCU) cannot diversify the layout of the video call screen, limiting user customization and convenience.

Innovation Solution

An apparatus and method that includes a receiver module to receive a composite image from a server, an image separating module to separate individual images, and a display module to arrange and display these images according to a predetermined layout on a video call terminal, allowing for customizable screen arrangements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a multipoint control unit (MCU) is used to receive and combine voices and images from multiple portable terminals, then multi-party video call functionality is enabled, but the layout of the multi-party video call screen cannot be diversified

Engineering Contradiction:
Improvelayout diversificationVSAvoidscreen arrangement flexibility
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The composite image received from the MCU is segmented into individual participant images through the image separating module. This segmentation enables each participant's image to be independently arranged and displayed according to different layout patterns, thereby achieving layout diversification while maintaining the existing MCU-based system architecture.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a composite image of multi-party video call participants is received and displayed on a portable terminal screen, then all participants can be viewed simultaneously, but the images cannot be arranged according to user preferences or customized layouts

Engineering Contradiction:
Improveuser customizationVSAvoidimage arrangement complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The display module dynamically arranges the separated participant images according to predetermined layout patterns or user-selected configurations. This dynamic arrangement capability allows the system to adapt to different user preferences and scenarios (such as spotlight mode, grid mode, or circular mode) without requiring complex manual arrangement operations from users.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system transitions from a single composite image display to a multi-dimensional arrangement space where individual participant images can be positioned in different spatial configurations. This dimensional transformation enables diverse layout patterns while maintaining simplicity in the underlying receiving and separating operations.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Productivity

If the MCU combines multiple voices and images into one unified stream, then transmission is simplified, but the terminal cannot display individual participant images in different positions or configurations

Engineering Contradiction:
Improvetransmission efficiencyVSAvoiddisplay configuration flexibility
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The system maintains the efficient unified transmission approach of the MCU while introducing segmentation at the receiving end. The image separating module divides the composite image into individual participant images, enabling flexible display configurations without compromising the transmission efficiency achieved through the MCU's unified stream approach.

Inventive Principle:
Principle #1Segmentation
