Multi-Stream Video Distribution Across Multiple Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for displaying multiple video streams on a single screen are limited in enhancing the user's viewing experience and do not allow for flexible or efficient distribution of video streams across multiple display devices.
Innovation Solution
A system that detects and directs multiple video streams to two or more display devices using stream identifications, allowing for automatic, manual, or combined automated and manual control, enabling panoramic video displays by assigning streams to specific display devices based on their positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple video streams are displayed on a single display device using picture-in-picture, then multiple views can be viewed simultaneously, but the viewing area is limited and the user experience is constrained
Solution Approach 1:
The patent divides the display system into multiple independent display devices instead of consolidating all video streams on a single screen. Each display device can show a different video stream in full-screen format, effectively segmenting the viewing experience across multiple physical screens to eliminate the picture-in-picture limitation while maintaining simultaneous viewing of multiple streams.
Solution Approach 2:
The patent transitions from a two-dimensional single-screen display to a multi-dimensional arrangement involving multiple display devices positioned at different spatial locations. This dimensional expansion allows each video stream to occupy its own full-screen display, dramatically increasing the total viewing area while preserving the ability to view multiple streams simultaneously.
2Adaptability or versatility
If video streams are manually directed to display devices, then flexible control is provided, but the operation becomes complex and time-consuming
Solution Approach 1:
The patent implements automatic stream direction capability where the system autonomously directs video streams to appropriate display devices based on predefined rules or user preferences stored in the system. This self-service mechanism eliminates the need for manual intervention in stream routing, significantly reducing operational complexity while maintaining adaptability through programmable configuration options.
Solution Approach 2:
The patent incorporates detection mechanisms that monitor the state of video streams and display devices, then automatically adjust stream direction based on detected conditions. This feedback loop enables the system to adapt to changing viewing requirements dynamically without requiring manual reconfiguration, balancing flexibility with ease of operation through intelligent automated control.
Data Source
AI summary
Multiple video streams, or other image information, from a DVD or other single source are selectively directed among two or more display screens. The video streams can be directed automatically, manually or by a combination of automatic and manual techniques. This allows the streams to be viewed simultaneously on different display screens to, e.g., increase the viewing area, provide selectable enhancement and control of video viewing, or for other purposes.
