Media Processor Time Slot Assignment for Multi-User 3D Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current media presentation systems face challenges in managing simultaneous viewing of multiple media programs with overlapping presentation schedules, particularly in ensuring that each viewer can only view one program at a time while maintaining high resolution and supporting both 2D and 3D content.
Innovation Solution
A media processor assigns periodic time slots to viewing apparatuses, allowing a presentation device to present different images to each apparatus, and includes a user interface that can be requested and controlled by users, using synchronization signals and shutter glasses to alternate lens activation for 3D viewing, enabling multiple users to view different programs independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single presentation device presents multiple media programs simultaneously, then multiple users can view different programs at the same time, but it becomes difficult to ensure that each user sees only their assigned program without interference
Solution Approach 1:
The presentation device divides the display area into multiple independent presentation areas, each dedicated to a specific media program. This segmentation ensures that content from different programs is spatially separated and can only be viewed by the intended user, eliminating cross-interference while enabling simultaneous multi-program presentation.
Solution Approach 2:
The system introduces a user identification mechanism as an intermediary between the presentation device and the display content. The device identifies which user is present and automatically presents the appropriate program in the corresponding presentation area, ensuring that each user receives only their assigned content without manual intervention.
2Manufacturing precision
If the presentation device presents high resolution images to multiple viewing apparatuses simultaneously, then image quality is maintained, but the system complexity increases
Solution Approach 1:
The system combines multiple full-resolution image presentations into a single composite image that contains all presentation areas. Each viewing apparatus captures the entire composite image and extracts only its assigned presentation area through coordinate information, eliminating the need for multiple separate high-resolution output channels while maintaining image quality.
Solution Approach 2:
Instead of generating separate high-resolution images for each user, the system creates one composite image that serves as a template. Each viewing apparatus receives this single composite image and extracts the relevant portion based on its assigned coordinates, reducing system complexity while preserving resolution quality.
3Adaptability or versatility
If the system supports both 2D and 3D content presentation, then content compatibility is improved, but the synchronization requirements and system complexity increase
Solution Approach 1:
The presentation device is designed to handle both 2D and 3D content through a unified processing framework. The device receives content in either format, processes it through the same segmentation and composite image generation mechanisms, and presents it appropriately, eliminating the need for separate processing pipelines for different content types.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution allows multiple users to view different media programs simultaneously with full resolution, supporting both 2D and 3D content, while ensuring each user sees only their assigned program, enhancing the viewing experience and efficiency in media consumption.
Implementation Method 1
The viewing apparatus can be synchronized to a time slot assignment by receiving a synchronization signal from the media processor. The media processor can then direct the presentation device to transmit the first HD stereoscopic stream on a first polarized portion of the presentation device, and the second HD stereoscopic stream on a second polarized portion of the presentation device.
Implementation Method 2
The media processor can then direct the presentation device to transmit the first HD stereoscopic stream on a first polarized portion of the presentation device, and the second HD stereoscopic stream on a second polarized portion of the presentation device.
