3D Video Interface Unit for Universal Goggle Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D video systems require proprietary goggles that must be compatible with the video playback system, limiting user flexibility and compatibility with different systems.
Innovation Solution
An interface unit captures video data from 3D devices, extracts synchronization signals, and generates control signals to alternate between left and right eye frames, allowing any compatible viewing device to display 3D content without the need for proprietary goggles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proprietary goggles are used to ensure compatibility with the video playback system, then the synchronization between goggles and 3D display is reliable, but the adaptability to different systems is reduced
Solution Approach 1:
An interface unit is introduced as an intermediary device between the 3D video playback system and the goggles. This interface unit captures video data from the playback system, extracts vsync signals, generates appropriate control signals, and transmits them to the goggles. This mediator enables universal compatibility while maintaining reliable synchronization without requiring proprietary goggles for each system.
Solution Approach 2:
The interface unit is designed with universal functionality to work with any 3D video playback system. It can capture video data from different sources, extract synchronization signals from various formats, and generate control signals compatible with different goggle types. This multi-functional design eliminates the need for system-specific proprietary goggles.
2Measurement precision
If proprietary goggles are required for each video playback system, then the control signal synchronization is precise, but the device complexity increases
Solution Approach 1:
The interface unit serves as a standardized intermediary that handles all synchronization complexity internally. It extracts vsync signals from the video data stream, processes timing information, and generates precise control signals for the goggles. This consolidates the synchronization complexity into a single device rather than requiring complex proprietary integration for each goggle model.
Solution Approach 2:
The interface unit extracts the essential vsync synchronization signals from the video data stream and separates them from the main video content. By extracting only the necessary timing information, the system maintains precise synchronization while simplifying the overall architecture, as the goggles only need to receive and respond to the extracted control signals rather than process entire video streams.
Data Source
AI summary
An interface unit is described that comprises a buffer for storing captured video data generated by a three dimensional (3D) device intended for a 3D monitor. The interface unit further comprises a synchronization signal extractor configured to extract vertical synchronization (vsync) signals from the video data and a control signal unit configured to derive control signals for a viewing device based on the stored vsync signals. The interface unit transmits the control signals to the viewing device.
