Screen Sharing via Server Intermediary for Local and Remote Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen sharing methods in multimedia conferences lack flexibility, as they typically require users to join the conference through a terminal device with a multimedia conference application, limiting the ability to share screens with both local and remote devices efficiently.
Innovation Solution
A screen sharing method that combines local screen projection with multimedia conferences, where shared screen data is sent via a server to a target participant device upon detecting a screen sharing operation, allowing both local and remote devices to display the shared screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users join multimedia conference through terminal device with multimedia conference application, then conference participation is achieved, but screen sharing flexibility is limited
Solution Approach 1:
The patent uses the server as an intermediary to enable screen sharing between the first terminal device and the second terminal device. The first terminal device sends screen sharing data to the server, which then transmits it to the second terminal device, eliminating the need for the second device to have conference application requirements and enabling flexible screen sharing across different device types.
2Adaptability or versatility
If screen sharing is achieved among terminal devices in multimedia conference, then remote sharing is enabled, but local display sharing is not efficiently supported
Solution Approach 1:
The patent makes the server a universal intermediary that handles both local display sharing and remote screen sharing through the same mechanism. The server receives screen sharing data from the first terminal device and can distribute it to both local display devices and remote terminal devices, enabling the system to serve multiple sharing scenarios with a unified approach.
3Productivity
If traditional screen sharing method is used, then simple device pairing is achieved, but multi-device simultaneous sharing is limited
Solution Approach 1:
The server acts as a central intermediary that can simultaneously manage multiple screen sharing sessions. The first terminal device sends screen sharing data to the server, which then distributes it to multiple second terminal devices concurrently, enabling efficient one-to-many screen sharing without requiring complex peer-to-peer coordination between devices.

AI summary
A screen sharing method, a screen sharing apparatus and an electronic device are provided according to embodiments of the present disclosure. An embodiment of the method includes sending, in response to detecting a screen sharing operation after paired with a target display device for screen projection, shared screen data via a server to a target participant device in a multimedia conference, to trigger the target participant device to display a shared screen based on the shared screen data, where the target participant device includes the target display device. By the method, the screen sharing is realized by combining local screen projection and a multimedia conference.
