Dynamic Media Stream Mapping for Multi-User 3D Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D viewing technologies for multiple users on a shared screen lack flexibility, requiring users to select between fixed content streams using glasses with fixed polarization or shutter phases, limiting dynamic content adaptation and user-specific experiences.
Innovation Solution
A media distribution management unit that maps alternative content into a single media stream based on user profiles, allowing dynamic allocation and playback of main and alternative content, enabling multiple users to see different views without needing individual screens or glasses with fixed settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users wear glasses with fixed polarization or shutter phase to view different content streams, then content separation for multiple users is achieved, but user flexibility and dynamic content adaptation are limited
Solution Approach 1:
The patent applies dynamics by making the content assignment to polarization channels dynamic rather than fixed. The system can reassign which content stream is associated with which polarization channel based on user profile and real-time conditions, allowing the same physical glasses to access different content dynamically without changing the glasses themselves
Solution Approach 2:
The system changes the parameter of content-channel mapping dynamically. Instead of fixed mapping between glasses polarization and content streams, the system allows the content parameter to be reassigned to different polarization channels based on user authentication and profile, enabling flexible content adaptation without physical changes to the viewing device
2Adaptability or versatility
If multiple content streams are provided for multiple users, then user-specific content is achieved, but system complexity and channel management increase
Solution Approach 1:
The system applies universality by using a single shared screen and limited number of content channels to serve multiple users with different content preferences. The same infrastructure (screen, channels, glasses) serves multiple functions by dynamically assigning different content to different users based on their profiles, eliminating the need for separate dedicated systems for each user
3Ease of operation
If fixed content streams are assigned to specific glasses configurations, then content separation is simplified, but user experience individualization is reduced
Solution Approach 1:
The system implements feedback by authenticating users and retrieving their profiles to determine what content they should see. The system continuously monitors user identity and dynamically adjusts content assignment based on this feedback, ensuring each user receives personalized content while maintaining simple operation through automatic authentication and assignment
