Tiled HDMI Window Management in A/V Hubs
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, which lead to cumbersome navigation and user frustration.
Innovation Solution
An audio/video (A/V) hub that communicates with portable electronic devices and content sources, providing display instructions for HDMI content to be shown in a tiled window on a display, using a control circuit that receives user interface activity and sends requests for HDMI content based on user selections, allowing for intuitive control and efficient content management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple content sources are displayed simultaneously on high-resolution displays, then content viewing capability is improved, but interface circuit bandwidth and processing capacity are exceeded
Solution Approach 1:
The display area is segmented into multiple tiled windows, each displaying content from different content sources. The A/V hub divides the high-definition content into separate video streams that are rendered in individual windows on the display, allowing simultaneous viewing of multiple content sources without overwhelming the interface circuit bandwidth.
Solution Approach 2:
The system transitions from displaying content in a single full-screen view to a multi-window tiled layout. By organizing content sources spatially in a grid pattern across the display, the system enables simultaneous viewing of multiple HD content sources while managing bandwidth through spatial distribution rather than temporal switching.
2Ease of operation
If traditional menu navigation is used to select content sources and displays, then content selection is achieved, but user operation time and complexity increase
Solution Approach 1:
The A/V hub automatically detects available content sources and configures the tiled window display without requiring users to navigate through multiple menu screens. The system self-configures by identifying connected devices, retrieving their content capabilities, and automatically populating the tiled display layout, thereby eliminating cumbersome manual navigation.
Solution Approach 2:
The A/V hub performs preliminary detection and configuration of content sources before user interaction. By pre-identifying available devices, their content types, and display capabilities in advance, the system prepares the tiled window layout proactively, so that when users interact with the system, content is already ready for immediate display without requiring time-consuming menu navigation.

AI summary
An audio/video (A/V) hub determines display instructions specifying information to be displayed on a display in an A/V display device that includes icons associated with content sources. Then, the A/V hub provides the display instructions to the A/V display device for display on the display. In response to receiving a user selection of a content source based on activation of a single command feature in a portable electronic device that is associated with the content source, the A/V hub provides a request for high-definition multimedia-interface (HDMI) content to the content source. When the A/V hub receives the HDMI content from the content source, the A/V hub provide the HDMI content and second 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.
