Multi-Perspective Media Display via Temporal Division
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3-D television systems lack the ability to provide multiple users with unique and simultaneous viewing experiences of the same program from different perspectives without spatial division of the screen, limiting the immersive experience for viewers.
Innovation Solution
A system that receives media content via multiple video streams, each associated with a different viewing perspective, determines the location of viewers relative to defined viewing zones, and selects the appropriate video stream for each viewer, allowing different perspectives to be displayed simultaneously on a single screen by using temporally divided content and specialized viewing glasses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional 3-D television systems are used, then a single viewing perspective is provided to all viewers, but the ability to provide multiple unique viewing experiences simultaneously is lost
Solution Approach 1:
The patent segments the viewing experience by dividing the audience into different viewing zones (e.g., left zone, right zone) and assigning different video streams to each zone. This allows multiple perspectives to be delivered simultaneously to different groups of viewers without requiring complex individual tracking of each viewer's position.
Solution Approach 2:
The patent introduces specialized viewing glasses as an intermediary device that works in conjunction with the display system. These glasses help deliver the correct perspective to each viewer based on their location, simplifying the overall system architecture by using a passive intermediary rather than active tracking of each viewer.
2Reliability
If multiple video streams are processed for different perspectives, then viewer immersion is enhanced, but processing requirements and system complexity increase
Solution Approach 1:
The system segments the processing load by handling different video streams separately for different viewing zones rather than processing all perspectives for all viewers. This reduces overall processing complexity while maintaining high-quality immersive experiences for each group.
Solution Approach 2:
The patent processes multiple video streams beyond what a single perspective would require, but only to the extent needed for the different viewing zones. This partial processing approach enhances viewer immersion while avoiding the excessive processing that would occur if all perspectives were processed for all potential viewers.
3Adaptability or versatility
If screen time is divided spatially, then different perspectives can be shown simultaneously, but the immersive experience is reduced
Solution Approach 1:
The patent uses temporal division where different video streams are displayed at different time periods within each frame cycle. The display alternates between showing different perspectives rapidly, and the specialized glasses synchronize with this temporal pattern to deliver the correct perspective to each viewer at the right time, maintaining immersion while enabling multi-perspective capability.

AI summary
A method includes receiving media content of a particular program at a media device. The media content of the particular program is received via a plurality of video streams, where each of the plurality of video streams is associated with a different viewing perspective. The method includes determining locations of one or more viewers of a display device relative to a plurality of viewing zones of the display device. The method also includes selecting a video stream of the particular program to display to each viewer of the one or more viewers based on the location of each viewer. One video stream is selected for each viewer, and different video streams are selected for viewers in different viewing zones. The method further includes sending the selected video streams to the display device from the media device.
