Electronic Device Mitigating Audio Video Stream Degradation
Solution Overview
Problem
Video communication sessions in marginal coverage areas experience degradation due to unreliable over-the-air networks, leading to poor user experience as participants may be unaware of the degraded transmit uplink, affecting both audio and video quality.
Innovation Solution
An electronic device with sensors and a controller that autonomously detects and mitigates audio/video stream degradation by altering transmission rates and alerting participants, enabling dynamic buffering and playback of missed content to maintain session quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If participants use electronic devices in marginal coverage areas with OTA networks, then video communication sessions can be conducted in diverse venues, but the transmit uplink experiences degradation affecting audio and video quality
Solution Approach 1:
The system performs preliminary actions by detecting transmission quality degradation before it significantly impacts the communication session. The controller continuously monitors transmission quality metrics and proactively identifies degradation conditions, allowing the system to take corrective actions (such as alerting participants or adjusting transmission parameters) before the degradation severely affects audio and video quality. This preliminary detection and response mechanism resolves the contradiction by maintaining reliability while preserving venue flexibility.
2Ease of operation
If the electronic device autonomously detects and mitigates transmission degradation, then user experience is improved, but the device complexity increases
Solution Approach 1:
The electronic device implements self-service by autonomously detecting transmission quality degradation and initiating mitigation actions without requiring external intervention. The controller automatically monitors transmission quality, identifies degradation conditions, and executes corrective measures such as alerting participants or adjusting transmission parameters. This self-service capability improves user experience by eliminating the need for manual intervention while the automation of these functions minimizes the perceived complexity for users.
Solution Approach 2:
The system employs feedback mechanisms where the controller continuously monitors transmission quality metrics and uses this information to detect degradation conditions. The feedback loop enables the system to automatically adjust transmission parameters or alert participants when degradation is detected. This feedback-driven approach improves ease of operation by making the system responsive to actual transmission conditions while managing device complexity through intelligent, data-driven decision-making.
3Loss of information
If verbal exchanges are used to inform participants about degraded transmit uplink, then participants are made aware of the issue, but the video communication session is interrupted
Solution Approach 1:
The electronic device acts as an intermediary by automatically detecting and communicating transmission quality degradation to participants through the device's interface. Instead of relying on verbal exchanges between participants, the controller monitors transmission quality and directly informs the local participant of the degraded condition. This intermediary role eliminates the need for participants to verbally communicate the issue, thereby preventing session interruptions while ensuring transmission quality awareness is maintained.
Data Source
AI summary
An electronic device, computer program product, and method are provided that autonomously mitigates degraded transmissions of an audio/image stream from an electronic device to a video communication session. The electronic device communicates at least one of an image stream and an audio stream to other second electronic device(s). In response to receiving an indication that the at least one of the image stream and the audio stream is degraded, a controller presents a transmission quality degraded report using at least one display device to prompt mitigation. The controller can configure the electronic device to mitigate the degraded at least one of the image stream and the audio stream by altering the at least one of the image stream and the audio stream to support transmission via a lower data rate. The electronic device communicates the altered at least one of the image stream and the audio stream to the session.
