Host Preview Injection for Remote Desktop Sessions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In remote desktop configurations, network projectors lack keyboard and mouse interfaces, making it difficult for presenters to manipulate desktop displays, and streaming features often result in poor performance and resolution mismatches, limiting the user's ability to view and interact with projected content effectively.
Innovation Solution
A system that captures and displays the actively changing desktop in a remote desktop session on the host's logon screen, allowing users to preview and interact with the projected content using their familiar keyboard and mouse devices while maintaining focus on their laptop screen, by using a Desktop Preview Injection Component and Desktop Screen Capture Component to provide a graphical user interface on the host's logon screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a network projector is used for remote desktop display, then display output is improved, but keyboard and mouse interfaces are lost
Solution Approach 1:
The patent introduces a local display component as an intermediary device. This component receives remote desktop session information from the host system and presents it through a graphical user interface on the local display, enabling users to view and interact with the remote desktop without requiring physical keyboard or mouse connections to the remote system.
Solution Approach 2:
The patent creates a visual copy of the remote desktop session on the local display. By capturing and rendering the remote desktop interface locally, the system allows users to interact with a replica of the remote environment using their local input devices, eliminating the need for direct physical connection to the remote system.
2Illumination intensity
If streaming feature is used to connect with remote projector, then display transmission is improved, but performance and resolution are worsened
Solution Approach 1:
The patent segments the display transmission into two independent paths: one for the remote desktop session data and another for the local display output. This allows the remote desktop to maintain its optimized performance and resolution settings while the local display handles the projection output separately, avoiding resolution mismatches and performance degradation.
Solution Approach 2:
The patent maintains different display parameters for the remote desktop session versus the local projection output. The remote session preserves its original resolution and performance characteristics, while the local display component independently optimizes for projection requirements, allowing each system to operate at its optimal parameters without compromise.
3Adaptability or versatility
If remote desktop connection is established, then network access is improved, but input device manipulation is worsened
Solution Approach 1:
The local display component serves as an intermediary that receives remote desktop session information and presents it through a graphical user interface on the local display. This enables users to interact with the remote desktop using their local keyboard and mouse devices without requiring physical connection to the remote system, maintaining network access while improving input device manipulation.
Solution Approach 2:
The patent replaces the need for direct mechanical connection between input devices and the remote system with a software-based communication channel. The remote desktop session is accessed through network protocols and rendered locally, substituting the mechanical direct-connection requirement with a software intermediary layer that maintains versatility while improving ease of operation.

AI summary
Updated image views of an actively changing desktop, in a remote desktop session being shared by a Remote Desktop terminal server, are displayed on the host's logon screen. Specifically, a Microsoft Window's based computer (host), which is communicating with a network projector (client) through a remote desktop connection, provides continually updating image views of the desktop being hosted in a remote desktop session onto the host screen such that a user locally positioned near the host may preview the desktop content being provide to, and output by, the remote projector.
