Solution Overview

Problem

Conventional telepresence technologies limit image switching to within the same capture scene, restricting the ability to seamlessly switch between images from different capture scenes across multiple sites in a multi-screen and multi-display conference scenario.

Innovation Solution

A multi-content media communications method and system that allows for the creation and management of media advertisement messages with unique capture identifiers and scene entries, enabling the compounding of individual media captures into multi-content media captures, which can be switched and synchronized across sites, facilitating the display of content from multiple sources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If image switching is limited to within the same capture scene, then system complexity is reduced and management is simplified, but the versatility and flexibility of media content switching across multiple sites is restricted

Engineering Contradiction:
Improvemedia content switching capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments media content into individual media captures (IMC) and capture scene entries (CSE) with unique identifiers. Each IMC represents a discrete media source that can be independently managed and switched, while CSE groups related IMCs from the same physical location. This segmentation enables flexible recombination and switching across sites without managing entire scene bundles, resolving the contradiction by providing versatility through modular units while keeping individual unit management simple.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimension of identification by adding unique capture identifiers (capture ID) that transcend the traditional capture scene boundary. This allows media content to be identified and switched based on content identity rather than location-based scene grouping, enabling cross-site switching while maintaining systematic organization through the dual-layer identification structure (capture ID + CSE ID).

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

2Loss of information

If multiple individual media captures are compounded into multi-content media captures, then the information richness and content variety are improved, but the complexity of managing and synchronizing these compounded captures increases

Engineering Contradiction:
Improveinformation richnessVSAvoidmanagement complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system merges multiple individual media captures (IMCs) into multi-content media captures (MCIMCs) by grouping IMCs that share the same capture ID. This combining preserves all original information from each IMC while creating a unified managed entity. The merge operation is facilitated by the common capture ID, which acts as a key for automatic grouping and synchronization, reducing management complexity despite the increased information richness.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent uses capture IDs as reusable identifiers that can be copied across multiple IMCs from different sites. When the same capture ID appears in IMCs from different capture scenes or sites, the system automatically recognizes them as corresponding media content and enables synchronized switching. This copying mechanism simplifies the management of compounded captures by providing a universal reference system.

Inventive Principle:
Principle #26Copying

3Measurement precision

If unique capture identifiers are assigned to individual and multi-content media captures across different sites, then the precision of media content identification and switching is improved, but the overhead of identifier management and conflict resolution increases

Engineering Contradiction:
Improvecontent identification precisionVSAvoididentifier management time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary assignment of unique capture IDs to media capture sources before actual media switching operations. Each media source (camera, screen capture, etc.) is pre-configured with a unique capture ID that remains consistent across different sites and capture scenes. This preliminary action eliminates the need for real-time identifier generation and conflict resolution during switching operations, reducing time overhead while maintaining high identification precision.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Instead of managing complex scene-level identifiers and trying to map between different site-specific scene structures, the patent inverts the approach by using simple, reusable capture IDs that are assigned to individual media sources. These capture IDs become the primary key for switching operations, while capture scene entries serve as secondary organizational containers. This inversion simplifies identifier management by focusing on the media source level rather than the scene level.

Inventive Principle:
Principle #13The other way round (Inversion)
