Content Processing Across Multiple Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video wall technologies struggle to efficiently display and interactively control data objects across multiple screens, particularly in scenarios where battery life and processing efficiency are concerns.
Innovation Solution
A method and system for processing content across two or more display devices, where one device acts as a master to determine and communicate subsets of data for rendering, allowing seamless and interactive display of a data object across multiple screens, with options for reducing processing load on one device to enhance battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If one device acts as master to determine and communicate subsets of data for rendering across multiple screens, then display coordination and interactivity are improved, but processing load and energy consumption increase
Solution Approach 1:
The patent divides the content dataset into multiple subsets, with each display device rendering only its assigned subset. This segmentation reduces the processing load on any single device while maintaining coordinated display across multiple screens, resolving the contradiction between display coordination and energy consumption.
Solution Approach 2:
Each display device performs only the partial action necessary for its specific subset rather than processing the entire dataset. This partial action approach allows multiple devices to work together efficiently, reducing individual energy consumption while achieving coordinated display across the system.
2Duration of action of moving object
If processing load is distributed across multiple devices, then battery life is extended, but system complexity increases
Solution Approach 1:
The system segments both the processing load and the dataset into manageable portions assigned to different devices. This segmentation enables battery life extension through distributed processing while controlling system complexity by using standardized communication protocols and clear division of responsibilities.
Solution Approach 2:
Each display device is designed to be multi-functional, capable of acting as either a master or slave device depending on system configuration. This universality reduces overall system complexity by using identical hardware platforms for different roles, while still achieving distributed processing for extended battery life.
3Stability of the object's composition
If a master device determines all subsets and communicates them to slave devices, then display consistency is improved, but processing efficiency and battery life deteriorate
Solution Approach 1:
The master device segments the dataset and communicates only the necessary subset definitions to each slave device. This segmentation approach maintains display consistency through centralized coordination while improving processing efficiency by allowing slave devices to independently render their assigned subsets without heavy processing loads.

AI summary
The methods enable display of a data object over two display apparatuses on the fly by operatively connecting two independent content processing devices together. Each device is arranged for rendering a subset of a dataset representing a data object When shown by display devices fed by each content processing devices, display of the subsets result in display of at least part of the data object in a contiguous way over the joint display area provided by the display devices. Furthermore, it enables interactive control of the way the data object is displayed over a display area provided by the first display apparatus controlled by the first content processing device and the second display apparatus controlled by the second content processing device. The method may be extended to more than two screens. The devices may operate in a master-slave configuration or in a peer-to-peer configuration, with or without a central server.
