3D Shutter Glasses Synchronization Signal Discrimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3-D LCD shutter glasses systems struggle to synchronize with multiple presentation devices showing different 3-D content, limiting viewers to a single synchronization signal and preventing them from viewing multiple 3-D programs simultaneously.
Innovation Solution
The system detects and discriminates between multiple synchronization signals using unique identifiers, allowing the shutter glasses to selectively lock onto and maintain synchronization with the desired 3-D program content, even when multiple devices are presenting different content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single synchronization signal is used for multiple presentation devices, then the shutter glasses can synchronize to one signal, but the viewer cannot view multiple 3-D programs simultaneously
Solution Approach 1:
The synchronization signal is segmented into multiple distinct signals, each associated with a different presentation device. The shutter glasses receiver is divided into multiple detection channels, each tuned to receive a specific synchronization signal from a specific device, enabling simultaneous viewing of multiple programs without signal interference
Solution Approach 2:
A signal identifier or tag is introduced as an intermediary element within each synchronization signal. This identifier allows the shutter glasses to distinguish between different synchronization signals from multiple presentation devices, enabling selective synchronization with the desired program while maintaining the ability to view multiple programs simultaneously
2Productivity
If multiple synchronization signals are transmitted from different presentation devices, then multiple 3-D programs can be presented, but the shutter glasses cannot synchronize to the correct signal
Solution Approach 1:
The shutter glasses receiver automatically detects multiple synchronization signals and their associated identifiers, then autonomously selects the correct signal based on the user's viewing context or manual input. This eliminates the need for complex manual synchronization selection by the user, maintaining ease of operation while supporting multiple programs
Solution Approach 2:
The system incorporates feedback mechanisms where the shutter glasses continuously monitor which synchronization signal is currently active and adjusts its synchronization accordingly. This feedback loop ensures that even in a multi-program environment, the shutter glasses remain synchronized with the intended program without requiring user intervention
3Reliability
If the shutter glasses are synchronized to one presentation device, then the 3-D effect is maintained, but the viewer cannot switch between different 3-D content
Solution Approach 1:
The synchronization system transitions from a static single-signal lock to a dynamic multi-signal capable system. The receiver can dynamically switch between different synchronization signals based on user selection or automatic detection, maintaining reliable 3-D synchronization with the currently selected program while enabling content switching between different presentation devices

AI summary
Three dimensional (3-D) program content viewing system in a media environment with different media presentation devices detects a first synchronization signal transmitted from a first synchronization signal source, wherein the first synchronization signal is associated with first 3-D program content and includes a first signal identifier. The system detects a second synchronization signal transmitted from a second synchronization signal source, wherein the second synchronization signal is associated with second 3-D program content and includes a second signal identifier. The system then receives a selection of one of the first synchronization signal and the second synchronization signal and discriminates between the first synchronization signal and the second synchronization signal based upon the first signal identifier and the second signal identifier. The system then controls a left lens and a right lens of 3-D shutter glasses in accordance with the selected one of the first synchronization signal and the second synchronization signal.
