Multi-Casting System for Interactive Live-Stream Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Miracast dongles limit interactive capabilities in educational or collaborative settings, as only one device can be mirrored on a large display, restricting real-time collaboration and optimal screen space utilization.
Innovation Solution
A method and system for interactive live-stream projection via a multi-casting system, which establishes a wireless connection between a receiving device and multiple sending devices, renders options for each sending device on the receiving device's UI, receives user input to select a sending device, and transmits the live-stream data of the selected device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Miracast dongles are used for screen mirroring, then wireless connection and convenience are improved, but multi-user interaction and collaborative capabilities deteriorate
Solution Approach 1:
The system segments the screen sharing functionality by allowing multiple sending devices to connect simultaneously to one receiving device, with each device being independently selectable. This segmentation enables multiple users to share their screens without conflict, resolving the limitation of single-device mirroring while maintaining wireless convenience.
Solution Approach 2:
The receiving device is designed to perform multiple functions: it can receive and display content from multiple different sending devices simultaneously, and the large display can show multiple screens. This multi-functionality allows the system to adapt to various collaborative scenarios, enhancing versatility while preserving ease of operation.
2Area of stationary object
If screen mirroring is used on large display, then display size is improved, but screen space optimization for education deteriorates
Solution Approach 1:
The large display screen space is segmented into multiple display areas, with each area dedicated to a different sending device. This segmentation allows multiple users to have their content displayed simultaneously in optimized portions of the screen, making better use of the available display area for educational purposes.
Solution Approach 2:
The system transitions from single-screen mirroring to multi-screen arrangement on the large display. By utilizing the two-dimensional space of the large display more effectively and arranging multiple screens in different positions, the system optimizes screen space utilization for educational content delivery.
3Adaptability or versatility
If multiple Miracast dongles are used simultaneously, then multi-device support is improved, but control competition and disruptions increase
Solution Approach 1:
The receiving device acts as an intermediary that manages connections from multiple sending devices. It provides a centralized control mechanism where users can select which device to view, eliminating control competition and disruptions that occur when multiple dongles operate independently without coordination.
Solution Approach 2:
The system implements feedback mechanisms where the receiving device provides information about connected sending devices and their current status. This feedback allows users to make informed selections and manage multiple devices smoothly, reducing control conflicts and improving ease of operation in multi-device scenarios.

AI summary
This disclosure relates to a multi-casting system and a method for interactive live-stream projection via the multi-casting system. The method includes establishing a wireless connection between a receiving device and a plurality of sending devices. The method further includes rendering at least one option corresponding to each of the plurality of sending devices on a user interface (UI) of the receiving device. The method further includes receiving a user input from a user of the receiving device. It should be noted that receiving the user input includes selecting a first option corresponding to a first sending device from the at least one option corresponding to each of the plurality of sending devices. The method further includes transmitting a live-stream data of the first sending device to the receiving device based on the user input.
