Remote Screen Display During Voice Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless networks do not effectively allow a recipient handset to be used as a remote screen for displaying content from an initiator handset during a voice call without the recipient storing or forwarding the content, which raises concerns about digital rights and content preservation.
Innovation Solution
The system employs a personal agent on the initiator handset to capture and transmit the screen buffer to a serving node, which then forwards it to the recipient handset, allowing rendering without storage or copying, using multiple Radio Access Bearer technology over both circuit-switched and packet-switched networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the recipient handset stores the screen buffer to enable display, then the display function is achieved, but digital rights are violated and content security is compromised
Solution Approach 1:
The patent introduces a serving node as an intermediary between the initiator and recipient handsets. The serving node receives the screen buffer from the initiator, processes it, and transmits it to the recipient. This intermediary architecture enables the recipient to display content without directly receiving or storing the original screen buffer, thereby maintaining digital rights protection while achieving the display function.
2Adaptability or versatility
If the recipient handset forwards the screen buffer to third parties, then content sharing is enabled, but content security and rights management are compromised
Solution Approach 1:
The serving node acts as a controlled intermediary that manages content distribution. It processes the screen buffer and transmits only the processed version to the recipient, preventing the recipient from obtaining the original screen buffer that could be forwarded to third parties. This maintains content security while enabling controlled sharing.
Solution Approach 2:
The patent creates a processed copy of the screen buffer through the serving node rather than transmitting the original. The recipient receives and displays this processed copy, which cannot be used to reconstruct or forward the original content, thereby preventing unauthorized distribution while enabling content sharing.
3Adaptability or versatility
If simultaneous CS and PS connections are supported, then remote screen display during voice call is enabled, but network complexity increases
Solution Approach 1:
The serving node is designed to handle multiple functions within a single network element: it manages both circuit-switched voice calls and packet-switched data transmission, processes screen buffers, and coordinates between different network domains. This multi-functionality reduces overall network complexity compared to having separate dedicated systems for each function.

AI summary
The present invention provides systems and methods for using a recipient handset as a remote screen for the initiator handset, while the two handsets are engaged in a voice call. The systems and methods allow a party to transmit its screen buffer to the other party during a voice call between the parties, without allowing the receiving party to store it or forward it to a third party.
