Partial Display Area Source Presentation via Decentralized Buffer Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems require manual and complex processes for presenting multiple visual sources in partial display areas, such as picture-in-picture (PIP) or picture-by-picture (PBP) modes, which is time-consuming and inflexible, especially when dealing with varied video formats and hardware limitations.
Innovation Solution
A system and method that allow plural information handling systems to interface with a display through physical or wireless connections, initiating sessions with a partial video buffer region to present visual information in PIP/PBP modes, using a multiplexor to direct secondary visual information to a display panel alongside primary information, with a communications protocol supporting decentralized resource assignment and remote setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual selection of secondary video source is used for PIP/PBP modes, then the display can show multiple sources, but the process becomes complex and time-consuming
Solution Approach 1:
The system enables information handling systems to automatically initiate and manage their own display sessions without requiring manual user configuration. Each IHS can independently request and establish a display session with the display device, automatically presenting its visual information in the appropriate partial display area based on session type (PIP or PBP).
Solution Approach 2:
The display device pre-configures multiple partial video buffer regions (PIP and PBP areas) with defined characteristics such as position, size, and supported formats. These regions are prepared in advance and made available to IHS through configuration information, eliminating the need for real-time manual setup when a new source needs to be displayed.
2Device complexity
If fixed resolution video formats are enforced for PIP/PBP, then the display hardware can be simplified, but flexibility to adapt to different input sources is reduced
Solution Approach 1:
The system dynamically adapts to different video formats and resolutions from various information handling systems. The display device receives configuration information from each IHS about its capabilities and requirements, then dynamically allocates appropriate partial video buffer regions with matching parameters. This allows the system to flexibly support multiple video formats without requiring complex pre-configuration for every possible format combination.
Solution Approach 2:
The display device modifies video buffer parameters (resolution, format, position, size) based on the specific requirements of each connecting IHS. Configuration information exchanged between IHS and display enables automatic parameter adjustment, allowing the same hardware to efficiently support diverse video sources with different resolutions and formats without manual intervention.
3Quantity of substance
If multiple PIP/PBP areas are provided, then more sources can be displayed simultaneously, but selecting and configuring multiple sources becomes more complex
Solution Approach 1:
Each information handling system independently initiates its own display session and automatically configures itself in an appropriate partial video buffer region. The system does not require manual user selection or configuration of multiple sources - each IHS self-registers and self-configures based on the display device's configuration information and available resources.
Solution Approach 2:
The display device provides a universal interface that can accommodate multiple types of information handling systems simultaneously. Each IHS type (smartphone, tablet, computer, IoT device) can initiate display sessions using the same protocol and configuration mechanism, regardless of which specific partial video buffer region is used. The system handles multiple sources uniformly through a single automated process.
4Duration of action of stationary object
If PIP/PBP window remains active until manual turn-off, then the display continuously shows selected sources, but user interaction is required to manage display state
Solution Approach 1:
Display sessions are automatically managed by the information handling systems themselves. Each IHS initiates its session and can independently terminate it based on its own operational needs without requiring user intervention. The system automatically handles session lifecycle management, including initiation, maintenance, and termination, based on the presence and activity of the connecting devices.

AI summary
A display presents picture-in-picture and/or picture-by-picture formatted visual information initiated by secondary information handling systems while the display presents primary visual information. The display broadcasts plural partial video buffer definitions to plural information handling systems that can selectively initiate network sessions to present visual images in areas of the display by storage of visual image information in a portion of the display video buffer. The secondary display area may present visual images for IoT or similar headless devices having relevance to an end user of a primary information handling system.
