Solution Overview

Problem

Current solutions for sharing and capturing video and presentation-based meetings are inefficient, requiring installed software, extensive server processing, and are cumbersome for multiple users, limiting real-time collaboration and sharing.

Innovation Solution

A browser-based capture service that allows users to initiate and share capture sessions easily, capturing audio, video, screen, and peripheral data, enabling multiple users to join and collaborate without the need for additional software or extensive server processing, with the ability to store and share captured media objects in near real-time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If installed software and extensive server processing are used for capture sessions, then capture quality and reliability are improved, but device complexity and ease of operation deteriorate

Engineering Contradiction:
Improvecapture session reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The peer device performs capture session operations autonomously without requiring extensive server processing. The initiating device sends a request to join, and the peer device independently manages the capture session, reducing server dependency and system complexity while maintaining reliability

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent extracts the capture session processing functionality from centralized servers and relocates it to the peer device itself. This extraction reduces server processing requirements and system complexity while maintaining capture quality through local processing

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If installed software is required for capture sessions, then capture functionality is improved, but ease of operation and adaptability deteriorate

Engineering Contradiction:
Improveplatform compatibilityVSAvoidaccessibility
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements a universal link-based access mechanism that works across multiple platforms and devices without requiring platform-specific installed software. The peer device can join capture sessions through a standardized link interface, enhancing both adaptability and ease of operation

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

Instead of requiring users to install software copies on each device, the patent uses a link that copies access rights and session information. The peer device obtains capture session access through receiving a link containing encoded session parameters, eliminating installation requirements while maintaining functionality

Inventive Principle:
Principle #26Copying

3Adaptability or versatility

If multiple users are supported in capture sessions, then collaboration capability is improved, but device complexity and processing requirements worsen

Engineering Contradiction:
Improvemulti-user collaborationVSAvoidsession management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the multi-user capture session management into discrete, manageable components. Each user device independently manages its own capture stream and joins the session through individual link authentication, reducing overall session management complexity while supporting multiple users

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a link-based intermediary mechanism that mediates between multiple users and the capture session. The link serves as a standardized interface that simplifies user authentication and session joining, reducing the complexity of managing multiple users while maintaining collaboration capabilities

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present technology pertains to initiating and then sharing a capture session. According to at least one example, the present technology includes receiving, from a first device, a request to initiate a shared capture session. In response, the first device launches a capture session that receives audio, video, and screen data from the first device. The first device can then share the capture session with another user, via a link. After a second user selects the link at a second device, audio and video data from the second device are added to the capture session. The capture session aggregates and captures the audio, video, and screen data from both devices. After the capture session ends, a captured media object from the capture session can be stored at the first device, and sent to the second device, and the content management system.
