Multi-Device Display Frame Sharing via RTSP and UIBC
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screen mirroring technologies can only provide one-to-one frame sharing, limiting educators' ability to simultaneously share multiple teaching themes or screen frames with students, thereby restricting their flexibility in interactive teaching activities.
Innovation Solution
A method and apparatus for sharing display frames that allow a first electronic apparatus to synchronously display its frames on multiple selected second electronic apparatuses, using real-time streaming protocol (RTSP) sessions and user input back channel (UIBC) connections to enable multi-link WiFi display and flexible frame sharing across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If screen mirroring technology is used for one-to-one frame sharing, then transmission quality is maintained, but the ability to simultaneously share multiple frames with multiple students is lost
Solution Approach 1:
The patent segments the frame sharing function by introducing a frame selection interface that allows the source device to divide and select specific frames for sharing. Multiple frames can be independently selected and shared with different sink devices simultaneously, transforming the traditional one-to-one sharing into a many-to-many sharing capability while maintaining manageable system complexity through modular frame selection.
2Adaptability or versatility
If multiple frames are shared simultaneously with multiple devices, then teaching flexibility is improved, but system complexity increases
Solution Approach 1:
The patent implements universality by designing a frame selection interface and multi-link WiFi display system that can handle multiple frame sharing scenarios through a unified mechanism. The same interface and protocol stack support both single-frame and multi-frame sharing, as well as one-to-one and many-to-many sharing patterns, reducing the need for separate configurations for different teaching scenarios.
3Ease of operation
If traditional screen mirroring is used, then system simplicity is maintained, but interactive teaching with multiple students is restricted
Solution Approach 1:
The patent applies preliminary action by implementing a frame selection interface that allows the educator to pre-select which frames will be shared with which sink devices before the actual sharing begins. This preliminary configuration simplifies the operation during teaching activities, as the system is already set up to handle multiple frame sharing scenarios without requiring complex real-time adjustments.

AI summary
A method and an apparatus for sharing display frame are provided. The apparatus includes a display unit, a communication unit, and a processing unit. In the method, a plurality of electronic apparatuses are searched by the processing unit through the communication unit, where each of the electronic apparatuses is configured to display a corresponding display frame. The processing unit selects one or a plurality of the electronic apparatuses, and synchronously displays at least first frame displayed by the display unit on one or a plurality of the selected electronic apparatus.
