Orchestrated Screen Sharing with Managed Receiver Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screen sharing technologies in meeting settings are inefficient, requiring participants to take turns connecting devices, leading to lost time and productivity, and lack control and access restrictions, allowing for potential disruptions.
Innovation Solution
A collaboration system where a master device controls which participant devices share their screens on a receiver, using a management server to lock the receiver and manage participant devices, ensuring seamless transitions and preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If participants take turns connecting their devices to the receiver for screen sharing, then each participant can share their screen, but the meeting loses time and productivity due to coordination overhead and repeated logins
Solution Approach 1:
The patent introduces a receiver device as an intermediary that maintains a persistent connection to the display system, while participant devices connect to the receiver rather than directly to the display. This intermediary architecture eliminates the need for repeated logins and coordination, as the receiver manages the persistent connection and routes content from multiple participants seamlessly.
2Ease of operation
If participants can freely connect to the receiver for screen sharing, then screen sharing is accessible to all, but unauthorized devices can take over the screen causing disruptions
Solution Approach 1:
The system dynamically adjusts access control based on the meeting state. During active screen sharing sessions, the receiver is configured to accept connections only from authorized participant devices identified by the orchestrator. The access control policy transitions from open (during setup) to restricted (during presentation), maintaining both ease of operation and meeting stability.
3Extent of automation
If a formal online meeting session is started to enable collaboration, then meeting control is established, but time is lost and media quality degrades due to routing through an online intermediary
Solution Approach 1:
The receiver is pre-configured with persistent connections and meeting control parameters before the actual screen sharing begins. The orchestrator pre-identifies authorized participant devices and configures the receiver's access control list in advance. This preliminary setup eliminates the need for time-consuming logins and connections during the meeting, reducing setup time while maintaining automated control.
4Reliability
If the receiver is locked to prevent unauthorized access, then security is improved, but legitimate participant devices cannot share their screens
Solution Approach 1:
The receiver implements dynamic access control that adapts to the current meeting context. During active sessions, the receiver maintains a restricted access list of authorized devices. When the orchestrator wants to switch presenters, the receiver dynamically updates its access control list to include the new presenter's device while excluding previous ones. This dynamic behavior maintains both security and flexibility throughout the meeting lifecycle.

AI summary
Systems and methods for allowing an orchestrator to manage screen sharing in a meeting between multiple user devices are described. The orchestrator can use a master device to start a sharing session and select user devices to join as participant devices. The orchestrator can also select at least one receiver for receiving shared media. Participant devices are displayed on the master device. The orchestrator can then select a participant device to act as a source, and a receiver to receive the shared media from the source. The master device can contact a management server to cause the selected participant device to being sharing its screen on the receiver.
