Stereoscopic Video Storage Full Resolution Streams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for storing stereoscopic video data often result in significant loss of pixel data and image degradation due to bandwidth limitations and compression techniques, leading to a compromised viewing experience.
Innovation Solution
Storing stereoscopic video data in two separate streams at full resolution, each with a minimum bandwidth of 40 Mb/s, allowing for equal image quality between the left and right eye streams and reducing the need for compression that degrades image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If stereoscopic video data is compressed using frequency and motion estimation steps, then file sizes are reduced, but image quality is compromised
Solution Approach 1:
The patent divides stereoscopic video data into two separate streams (left eye and right eye) that are processed and stored independently. This segmentation allows each stream to maintain full resolution without the quality degradation that occurs when merging streams into a single compressed format. The separate processing preserves pixel data while still enabling compression benefits through independent encoding of each eye's view.
2Productivity
If encoding methods merge distinct sets of streams into a single stream, then compression efficiency is improved, but video quality degradation becomes apparent
Solution Approach 1:
The patent maintains separate encoding pipelines for left and right eye streams, preventing the quality loss that occurs when streams are merged. Each stream undergoes independent compression and encoding processes, ensuring that the full resolution and pixel data integrity are preserved in both streams simultaneously, achieving both compression efficiency and quality preservation.
Solution Approach 2:
The patent changes the encoding parameters by treating each eye stream as an independent video stream with its own resolution and compression settings. This allows optimization of compression parameters for each stream individually, maintaining high compression efficiency while preserving the full pixel data and image quality of both streams without the degradation that occurs in merged-stream formats.
3Quantity of substance
If half-resolution video is encoded with intraframe frequency and motion estimation, then bandwidth is reduced, but significant pixel data is lost
Solution Approach 1:
The patent segments the video data into separate left and right eye streams, each maintained at full resolution. This segmentation eliminates the need to reduce resolution to half, as each stream independently retains complete pixel data. The separate encoding allows full-resolution compression without the pixel data loss that occurs in half-resolution formats.
4Device complexity
If current encoding methods are used, then storage complexity is reduced, but visible artifacts degrade the viewing experience
Solution Approach 1:
The patent uses separate encoding and storage of left and right eye streams, which simplifies the decoding process by avoiding complex de-multiplexing operations. This segmentation approach reduces storage and processing complexity while eliminating the visible artifacts that occur when merged streams are decoded, thereby improving viewing quality without increasing system complexity.

AI summary
A method for storing visual information on a storage medium is disclosed, whereby the method includes receiving a first visual information corresponding to a left eye and a second visual information corresponding to a right eye. The method further includes storing the first visual information in a first stream and the second visual information in a second stream on the storage medium, wherein the first stream and the second stream are each stored at full resolution. An information handling system (IHS) is further disclosed including a storage medium operable to store, at full resolution, a first stream of visual information corresponding to a left eye and a second stream of visual information corresponding to a right eye, wherein the first stream and the second stream are each stored at full resolution. The system may further include a playback device operable to read the storage medium and display the visual information.
