Video Display Device Confidential Communication Environment Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional broadcast receivers with call functions lack the ability to determine whether the communication environment is suitable for confidential communication, as third parties may inadvertently listen or view the communication due to the type of output device used.
Innovation Solution
A device information communication method is implemented in a video display device that obtains and shares device information with communication partners, allowing them to recognize the type of device connected and its settings, enabling the determination of a suitable communication environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional broadcast receivers with call functions are used, then basic communication capability is provided, but the ability to determine confidential communication environment is lost
Solution Approach 1:
The system performs preliminary acquisition and sharing of device information (output device type, connection status) before the actual communication takes place. This allows the communication partner to assess the confidentiality environment in advance and make informed decisions about whether to proceed with sensitive communications.
Solution Approach 2:
The system establishes a feedback mechanism where device information is continuously monitored and shared with communication partners. The partner can provide feedback about the suitability of the communication environment based on the shared device information, enabling dynamic adjustment of communication security measures.
2Ease of operation
If output devices are used for communication, then communication functionality is enhanced, but risk of third-party exposure increases
Solution Approach 1:
The system identifies and categorizes output devices (speakers, displays, headphones) before communication occurs, and shares this information with the partner. This preliminary assessment allows users to anticipate potential exposure risks and take preventive measures such as switching to private output devices for confidential calls.
Solution Approach 2:
The system introduces device information as an intermediary element between the communication parties. This intermediary provides transparent visibility into the communication environment, allowing partners to assess risks without directly observing the physical setup, and make informed decisions about information sharing.
3Reliability
If device information is shared with communication partners, then communication environment assessment is enabled, but system complexity increases
Solution Approach 1:
The system extracts only the essential device information elements needed for confidentiality assessment (output device type, connection status, device identifiers) and shares only these specific data points with communication partners. This selective extraction avoids overwhelming the system with unnecessary complexity while providing sufficient information for environment assessment.
Solution Approach 2:
The device information sharing mechanism is designed to be universal and adaptable to different communication scenarios and device types. The same basic framework handles various output devices (speakers, headphones, displays) and communication modes (voice, video, messaging) without requiring complex specialized processing for each case.
