Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for allowing a sub control device to operate screen content during multi-party video communication are cumbersome and insecure, often requiring password sharing or simultaneous operation, which can lead to security risks and operational failures.
Innovation Solution
A method and apparatus for transferring screen operation rights between devices through encrypted communication connections, allowing users to hand over, withdraw, and manage control rights dynamically, enhancing user initiative and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If password sharing method is used to allow sub control device to operate screen content, then user can perform remote operation, but security risk increases and operation becomes complicated
Solution Approach 1:
The patent introduces a control right transfer mechanism as an intermediary between the main control device and sub control device. Instead of directly sharing passwords or allowing unrestricted access, the system establishes a temporary, authenticated control channel where control rights are transferred only when needed and automatically returned afterward. This mediator approach enables secure remote operation without exposing credentials or creating permanent access vulnerabilities.
Solution Approach 2:
The patent implements dynamic control right management where the control authority can be transferred from the main control device to a sub control device temporarily, and then automatically returned. This dynamic mechanism allows the system to adapt control access based on real-time needs while maintaining security through automatic recovery of control rights, eliminating static password sharing vulnerabilities.
2Reliability
If simultaneous operation is required for screen control, then control accuracy is maintained, but user convenience deteriorates and operation efficiency decreases
Solution Approach 1:
The patent implements dynamic control right transfer where the main control device can temporarily transfer control rights to a sub control device, allowing sequential operation rather than requiring simultaneous operation. The control rights are automatically returned after the sub control device completes its operation, maintaining control accuracy while significantly improving user convenience and operation efficiency.
Solution Approach 2:
The patent establishes a control right transfer mechanism that prepares the system in advance for sequential operation. Before the sub control device needs to operate the screen, the main control device proactively transfers control rights, ensuring the sub control device can immediately perform operations without waiting for simultaneous availability or facing access restrictions.
3Reliability
If main control device manages all screen operations, then control security is maintained, but system complexity increases and response time increases
Solution Approach 1:
The patent segments the control management function by allowing the main control device to transfer control rights to sub control devices for specific operations. Instead of the main control device managing all operations centrally, the system divides control responsibilities based on temporary needs, reducing the complexity burden on the main control device while maintaining overall security through authenticated control right transfer.
Solution Approach 2:
The patent introduces control rights as an intermediary mechanism that simplifies the control management architecture. Rather than requiring complex centralized authentication and authorization systems for every operation, the main control device uses the control right transfer mechanism to delegate operations to sub control devices, reducing system complexity while maintaining security.
4Productivity
If control rights are transferred to sub control device, then operation efficiency improves, but risk of unauthorized access increases
Solution Approach 1:
The patent implements a control right transfer mechanism that prepares and executes control transfers only when explicitly requested and authenticated. The main control device proactively initiates the transfer process after verifying the sub control device's identity and intent, preventing unauthorized access before it can occur while enabling efficient operations when properly authorized.
Solution Approach 2:
The patent establishes a feedback mechanism where the main control device monitors and manages control right transfers. After transferring control rights to a sub control device, the system automatically detects when the sub control device completes its operation and initiates control right recovery, providing continuous feedback that prevents unauthorized prolonged access while maintaining operational efficiency during authorized periods.

AI summary
Embodiments of the present application disclose a screen control method and an apparatus. The method includes: in a case that an interface of multi-party video communication is displayed, receiving a first input by a first user; and in response to the first input, establishing a first communication connection between a first electronic device and a second electronic device. Both the first electronic device and the second electronic device are electronic devices participating in the multi-party video communication. The first communication connection is used to send a control instruction of the second electronic device on a screen display content of the first electronic device. In a case that the control instruction is received, a control operation corresponding to the control instruction is performed on the screen display content of the first electronic device.
