A/V Hub Tiled HDMI Display for Source Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing entertainment devices face challenges in simultaneously displaying high-definition multimedia-interface (HDMI) content due to interface circuit limitations and complex user interfaces, leading to cumbersome navigation and user frustration.
Innovation Solution
An audio/video (A/V) hub that communicates with portable electronic devices and display devices, receiving user selections to request and display HDMI content in a tiled window format, simplifying the user interface and reducing errors through dynamic adaptation based on device-state information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple HDMI content sources are displayed simultaneously, then content viewing capability is improved, but interface circuit bandwidth and processing capacity are overwhelmed
Solution Approach 1:
The display area is segmented into multiple independent tiled windows, each capable of displaying content from different HDMI sources simultaneously. The A/V hub divides the single display output into multiple discrete regions, allowing parallel content presentation without overwhelming the interface circuit bandwidth by processing all content through a single display pipeline.
2Adaptability or versatility
If complex menu navigation is provided for content selection, then content source identification capability is improved, but user operation complexity increases
Solution Approach 1:
The A/V hub automatically detects available HDMI content sources and configures tiled window displays without requiring users to navigate through complex menus. The system self-identifies connected devices, retrieves content metadata, and arranges displays autonomously, eliminating the need for manual source selection and reducing operational complexity while maintaining versatile content source identification.
Data Source
AI summary
In response to receiving user-interface activity information from a portable electronic device that specifies user selection of a content source, an audio/video (A/V) hub provides a request for high-definition multimedia-interface (HDMI) content to the content source based on the user selection. When the A/V hub receives the HDMI content from the content source, the A/V hub provide the HDMI content and display instructions to an A/V display device as frames with the HDMI content are received from the content source, so that the HDMI content is displayed in a tiled window on the display in the A/V display device while other HDMI content from another content source is displayed on the display.
