Media Processor Transcoding Stereoscopic Content for Multi-User Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current media content presentation systems face challenges in efficiently adapting stereoscopic media content to requesting devices with varying rendering capabilities, leading to suboptimal viewing experiences for multiple users with different device capabilities.
Innovation Solution
A media processor that records stereoscopic media content, determines the rendering capabilities of a requesting device, and transcodes the content accordingly, allowing for synchronized transmission and playback on devices with polarized or time-division multiplexing capabilities, enabling simultaneous multi-user viewing with optimal resolution and illumination adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If stereoscopic media content is transmitted to multiple requesting devices with different rendering capabilities, then multiple users can view content simultaneously, but image quality and resolution deteriorate due to incompatible device capabilities
Solution Approach 1:
The system segments the transcoding process into multiple independent rendering passes, where content is transcoded separately for each requesting device based on its specific capabilities. This allows each user to receive optimized content at full quality without compromising other users' viewing experiences.
Solution Approach 2:
The system dynamically changes rendering parameters (resolution, format, stereoscopic mode) based on each requesting device's capabilities. The media processor adjusts transcoding parameters to match device-specific requirements while maintaining optimal image quality for each user.
2Manufacturing precision
If content is transcoded for each requesting device, then optimal image quality is achieved for each device, but processing time and system complexity increase
Solution Approach 1:
The media processor is designed with multi-functional capability to handle multiple transcoding operations simultaneously. It can process different stereoscopic formats (side-by-side, top-bottom, interlaced) and convert to various output formats using the same hardware resources, reducing overall system complexity.
Solution Approach 2:
The system maintains continuous processing by implementing efficient buffering and streaming mechanisms. Multiple transcoding operations proceed in parallel without idle time, and the media processor continuously serves multiple requesting devices without interruption or quality degradation.
3Manufacturing precision
If high resolution content is transmitted to portable devices with limited processing power, then viewing quality improves, but energy consumption and device performance requirements increase
Solution Approach 1:
The system dynamically adjusts output parameters based on device capabilities. For portable devices with limited processing power, the media processor transcodes content to appropriate resolution levels and simplified stereoscopic formats that reduce energy consumption while maintaining acceptable viewing quality.
Solution Approach 2:
The system creates optimized copies of the original high-resolution content tailored to each device's capabilities. Instead of transmitting the full-resolution source material to all devices, it generates device-specific copies with appropriate compression and resolution levels.
