Real-Time View Synchronization for Immersive Multi-Screen Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video wall systems struggle to accurately synchronize multiple display screens when displaying 360-degree panoramic imagery, leading to disorienting asynchrony over time, especially in long-form digital experiences, and require specialized hardware, limiting their accessibility and usability for immersive digital media consumption.
Innovation Solution
A method for real-time view synchronization across multiple computing devices connected via a network, where a master device sends view synchronization messages to slave devices, adjusting their displays based on their relative positions to create a seamless, immersive experience without the need for specialized hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional video wall systems use multiple independent display screens, then the display area is increased, but synchronization precision deteriorates over time due to drift between independent timing mechanisms
Solution Approach 1:
The patent merges multiple independent timing mechanisms into a single synchronized timing system. A master timing signal is distributed to all display screens through the synchronization protocol, ensuring that all displays operate from a common time reference rather than independent clocks, thereby eliminating drift between screens.
Solution Approach 2:
The synchronization protocol incorporates feedback mechanisms where timing information is continuously exchanged between displays. The system monitors and adjusts timing parameters in real-time to maintain synchronization, compensating for any temporal variations between independent display devices.
2Manufacturing precision
If specialized hardware is used to achieve real-time synchronization, then synchronization precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces complex mechanical synchronization hardware with a software-based network protocol. Instead of using specialized synchronization hardware or mechanical linkages between devices, the system uses standard network communications to transmit timing information, achieving synchronization through software control rather than hardware complexity.
Solution Approach 2:
The synchronization protocol is designed to work with standard computing hardware and network infrastructure, making it universally applicable to different display systems. The same protocol can synchronize various types of displays (LCD, LED, projector) without requiring specialized hardware for each display type.
3Duration of action of moving object
If the duration of digital content is extended, then content versatility is improved, but synchronization precision deteriorates due to cumulative drift over time
Solution Approach 1:
The synchronization protocol operates continuously throughout the entire duration of the digital content, maintaining constant timing coordination between all display screens. Rather than synchronizing only at the beginning or end, the system continuously exchanges timing information to prevent any drift accumulation, ensuring synchronization is maintained from start to finish of long-form content.

AI summary
Embodiments relate to a method for synchronizing media playback across multiple computing devices on a network. Multiple display screens, each coupled to a computing device, can be arranged in a circular formation surrounding a user. For example, a special enclosure for the display screens may be constructed for this purpose. An immersive viewing experience is created for the user by synchronizing the views displayed on each screen. The multiple screens operate in unison to create a tiled view of a three-dimensional environment. This immersive experience can be referred to as a “Liquid Galaxy.” The experience is enhanced by allowing the user to view and navigate through such three-dimensional environments using an input device, such as, for example, a joystick or game controller.
