Remote Window Control via Video Call Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies restrict mobile remote access to visual pages during video calls, requiring a secured tunnel and client, limiting interaction capabilities on mobile terminals.
Innovation Solution
A method for real-time remote presentation and control of a visual page from a remote server to a mobile terminal during a video call, enabling interaction through DTMF, voice, touch screen, and motion sensor events without the need for a secured tunnel or client, using a Window Capture module and Window Input and Translate module to encode and transmit frames over a mobile network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a secured tunnel and client are used for remote access, then security is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent extracts the security mechanism from the endpoint device by implementing security validation at the application server level. Instead of requiring secured tunnels and clients at the mobile terminal, the system validates user credentials and authorizes access through the application server, which then manages the remote window access. This removes the security burden from the endpoint while maintaining protection.
Solution Approach 2:
The application server acts as an intermediary between the user and the remote window system. It validates credentials, authorizes access, and manages the remote window sessions without requiring the mobile terminal to implement complex security protocols. The server mediates all security-related operations, simplifying the endpoint requirements.
2Reliability
If a secured tunnel and client are required, then security is improved, but ease of operation worsens
Solution Approach 1:
The patent extracts security validation from the endpoint device to the application server. Users authenticate through the application server using simple credentials, and the server handles all security validation. This eliminates the need for users to configure secured tunnels or install specialized clients, making access as simple as opening a web browser while maintaining security through server-side validation.
3Adaptability or versatility
If real-time capture and encoding is performed, then interaction capability is improved, but use of energy and processing power increases
Solution Approach 1:
The system performs partial capture by selectively capturing only the remote window region rather than the entire desktop, and uses efficient encoding formats optimized for remote window sharing. This reduces the amount of data that needs to be processed and transmitted, lowering energy consumption while maintaining full interaction capability through the captured window content.

AI summary
A method for an application server at a remote window source for real-time remote capture, presentation and control of a visual window source created from a calling subscriber's mobile terminal during a video call is described. The method includes performing the call, displaying the remote window, capturing the remote window by a Window Capture module in real-time and analyzing an interactive input event initiated by the calling subscriber and sending back to the subscriber's mobile phone in encoded video call format. The method also includes waiting by an application instance at the remote window for the input event by the calling subscriber, initiating the input event and acting by the application server on the remote window, accordingly, such that the remote window produces a new window presentation which is captured in real time and transmitted and presented to the calling subscriber during a video call.
