Credentialed Volumetric Video Dynamic Object Concealment

Solution Overview

Problem

Existing volumetric video systems require multiple variations for different permission levels, leading to excessive computational resources and inefficiencies due to the need for extensive processing and storage of multiple volumetric videos.

Innovation Solution

Implement dynamic object concealment based on user permissions, using generative adversarial networks to adjust the display of volumetric videos in real-time, allowing secure access control without creating multiple versions of the video.

Engineering Contradictions & Design Principles

1Reliability

If multiple volumetric video variations are created for different permission levels, then secure access control is achieved, but computational resources and storage requirements increase excessively

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The system dynamically adjusts the volumetric video content based on user permission levels in real-time. Instead of creating multiple static versions, a single volumetric video is rendered with different levels of detail and object visibility depending on the authenticated user's credentials. This dynamic rendering approach maintains security while eliminating the need to store and process multiple video variations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes rendering parameters such as level of detail, object visibility, and geometric complexity based on user permission levels. By adjusting these parameters during runtime rather than creating separate videos, the system achieves secure access control without the computational overhead of maintaining multiple video versions. The same base volumetric video is rendered with different parameter settings for different users.

2Adaptability or versatility

If multiple volumetric video variations are created for different permission levels, then access control for different users is enabled, but storage requirements and processing overhead increase

Engineering Contradiction:
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

A single volumetric video file serves multiple functions by being rendered differently for users with different permission levels. The same base video contains all objects and data, but the rendering process selectively displays or conceals elements based on user credentials. This universal approach eliminates the need for multiple separate video files while maintaining versatile access control.

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

Solution Approach 2:

The system dynamically determines which objects to conceal or display based on real-time user authentication and permission verification. This dynamic approach allows a single video file to adapt to different user requirements without requiring multiple static versions, thereby reducing storage requirements while maintaining adaptability.

Inventive Principle:
Principle #15Dynamics

3Ease of manufacture

If traditional volumetric video systems are used without dynamic concealment, then implementation is simpler, but computational resources are wasted on processing and storing multiple video versions

Engineering Contradiction:
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The system introduces dynamic permission-based concealment into the volumetric video rendering pipeline. This is implemented by adding a permission verification step that determines which objects should be concealed based on user credentials, then applying selective concealment during rendering. This maintains relative implementation simplicity while dramatically improving computational efficiency by eliminating the need for multiple video versions.

Principle #15Dynamics
