Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Stereoscopic media often exhibits quality discrepancies between its left and right channels due to asymmetric compression techniques, leading to suboptimal viewing experiences for a significant portion of the population, particularly those with a dominant right eye.

Innovation Solution

Systems and methods that identify the viewer's dominant eye and modify stereoscopic media by performing mirror and swap functions on the lower-quality media channels to ensure the higher-quality channel is displayed to the dominant eye, enhancing the perceived quality without significant processing complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If asymmetric compression techniques are used for stereoscopic media, then coding efficiency is improved, but image quality of one media channel deteriorates

Engineering Contradiction:

Improvecoding efficiencyVSAvoidimage quality

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The system inverts the conventional approach by detecting which media channel has lower quality and swapping it with the higher quality channel before display. Instead of accepting the quality degradation from asymmetric compression, the system actively corrects it by inverting the channel assignment, ensuring the higher quality channel is delivered to the dominant eye regardless of the compression asymmetry used during encoding.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The system changes the parameter of channel quality distribution by detecting quality metrics of both media channels and dynamically adjusting which channel is assigned to which eye based on the viewer's dominant eye determination. This parameter change ensures optimal quality delivery while maintaining the efficiency benefits of asymmetric compression.

2Quantity of substance

If asymmetric compression techniques are used for stereoscopic media, then transmission bandwidth is optimized, but perceived quality for dominant eye viewers deteriorates

Engineering Contradiction:

Improvebandwidth efficiencyVSAvoidperceived quality

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The system implements feedback by determining the viewer's dominant eye and using this information to dynamically adjust media channel assignment. The feedback loop detects quality metrics, identifies the dominant eye, and swaps channels accordingly, ensuring that bandwidth efficiency from asymmetric compression does not compromise perceived quality for the majority of viewers.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system inverts the conventional assumption that asymmetric compression always benefits the viewer by actively detecting and correcting channel quality mismatches. By swapping the lower quality channel with the higher quality channel when the dominant eye would receive the lower quality channel, the system maintains bandwidth efficiency while ensuring optimal perceived quality.

Inventive Principle:

Principle #13The other way round (Inversion)

3Productivity

If media channels are created with different quality levels, then compression efficiency is improved, but viewing experience for significant portion of population deteriorates

Engineering Contradiction:

Improvecompression efficiencyVSAvoidviewing experience

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The system inverts the conventional approach by not accepting the quality disparity as a given but actively correcting it through channel swapping. This ensures that compression efficiency gains from creating media channels with different quality levels do not translate to deteriorated viewing experiences for the majority of viewers with right-eye dominance.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The system dynamically changes the delivery parameters by adjusting which media channel is assigned to which eye based on dominant eye detection. This parameter adjustment ensures that the viewing experience remains optimal for the significant portion of population with right-eye dominance while maintaining the compression efficiency benefits of asymmetric media creation.

AI summary

Systems and methods are provided for enhancing playback of stereoscopic media. The dominant eye of a viewer is identified, and the lower-quality media channel segment of received stereoscopic media is also identified. In response to the lower-quality media channel being mapped to the dominant eye of the viewer, the left-eye media in the left-eye media channel is mirrored to generate a mirrored right-eye media, and the right-eye media in the right-eye media channel is mirrored to generate a mirrored left-eye media. In the stereoscopic media, the left-eye media is replaced with the mirrored left-eye media, and the right-eye media is replaced with the mirrored right-eye media to generate a modified stereoscopic media. The modified stereoscopic media is then displayed to a viewer to provide a higher quality viewing experience.
