Display Device Control for Multi-View Video Call Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices struggle to efficiently manage video calls while simultaneously displaying multiple content streams, leading to unclear handling of content prioritization and resolution compatibility during multi-view screen operations.
Innovation Solution
A display device equipped with multiple decoders and a processor that identifies and outputs a video call screen through a partial screen corresponding to the appropriate content, based on a video call request, while managing multiple content streams by decoding and displaying them through partial screens with compatible resolutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple content streams are displayed simultaneously through partial screens, then the multi-view screen functionality is improved, but the video call service quality deteriorates due to unclear content prioritization
Solution Approach 1:
The display screen is divided into multiple partial screens that can independently display different content streams. When a video call is detected, the system segments the display resources by stopping decoding of non-essential content streams and allocating resources to decode and display the video call screen with higher priority, thus resolving the contradiction between multi-view functionality and video call quality
Solution Approach 2:
The system dynamically adjusts content prioritization based on real-time detection of video call requests. The processor monitors for video call signals and dynamically switches between multi-view mode and video call mode, ensuring that video call service quality is maintained when needed while allowing multi-view functionality during normal operation
2Adaptability or versatility
If content resolution compatibility is not managed, then the display flexibility is improved, but the video call screen output quality deteriorates
Solution Approach 1:
The system changes the resolution parameter of decoded content based on the detected video call requirements. When a video call is detected, the system adjusts the resolution parameter to match the video call screen requirements, ensuring optimal output quality for video calls while maintaining the ability to display various content resolutions in multi-view mode
3Quantity of substance
If all content streams are decoded simultaneously, then the content availability is improved, but the processing efficiency deteriorates during video call operations
Solution Approach 1:
The system applies partial decoding action by stopping the decoding of non-essential content streams when a video call is detected. Instead of maintaining all content streams active, the system selectively stops decoding for content that is not needed during video call operations, thereby improving processing efficiency while maintaining content availability for the active video call

AI summary
An example operating method of a display device for displaying a multi-view screen including a plurality of partial screens includes respectively outputting a plurality of pieces of content, which are individually decoded, through the plurality of partial screens, identifying at least one of the plurality of pieces of content, based on a video call request, and outputting a video call screen through at least one partial screen corresponding to the identified at least one content from among the plurality of partial screens.
