Immersive Video Format Transformation for Native-Quality Streaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spatial computers and streaming technologies struggle to support various immersive video formats, resulting in poor video quality and limited interactivity, with traditional systems requiring long loading times or compromising quality for immediate access.
Innovation Solution
A system and method for transforming immersive video from a first format into a second format, enabling fast loading times and true streaming at native quality through micro-segmentation, progressive composition, and parallel transformation techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional spatial computers download complete immersive video files before playback, then video quality is maintained at native resolution, but loading time becomes excessively long (30-45 minutes for 20 GB files)
Solution Approach 1:
The patent segments the immersive video file into multiple smaller chunks or segments that can be downloaded and processed independently. This allows the system to begin playback before the entire file is downloaded, significantly reducing perceived loading time while maintaining native video quality through progressive decoding and rendering of segments.
Solution Approach 2:
The system performs preliminary actions by pre-processing and pre-segmenting video content before delivery to the spatial computer. Metadata, indexing structures, and segment headers are prepared in advance, enabling the client to start decoding and displaying video segments as they arrive without waiting for complete file download.
2Speed
If immersive video is streamed without format transformation, then processing speed is maintained, but compatibility with various spatial computers is limited
Solution Approach 1:
The patent introduces an intermediary format transformation system that converts source immersive video into multiple output formats optimized for different spatial computer platforms. This mediator layer handles format adaptation transparently, allowing fast processing of standardized intermediate representations while generating device-specific optimized outputs, thus achieving both speed and compatibility.
Solution Approach 2:
The system dynamically changes video format parameters (codec type, resolution, bitrate, container format) based on the target spatial computer's capabilities. By transforming video parameters to match device specifications, the system achieves broad format compatibility while maintaining efficient processing through parameter-optimized encoding schemes.
3Loss of time
If immersive video files are compressed for faster loading, then loading time is reduced, but video quality deteriorates
Solution Approach 1:
The patent applies partial compression selectively to non-critical video segments or uses excessive action by applying advanced compression algorithms that achieve high compression ratios with minimal quality loss. Critical visual information is preserved at higher quality levels while less noticeable areas undergo greater compression, enabling faster loading without perceptible quality degradation.
