Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing systems for synthetic broadcasting within closed networks are used, then basic audiovisual content sharing is enabled, but latency and echo issues occur due to lack of efficient real-time synchronization mechanisms
Solution Approach 1:
The system performs preliminary actions by pre-establishing communication channels and pre-synchronizing clocks between devices before actual audiovisual content sharing begins. This preparation ensures that when content is shared, the synchronization is already in place, minimizing latency and echo issues during real-time transmission.
Solution Approach 2:
The system implements feedback mechanisms where devices continuously monitor transmission delays and echo levels, then automatically adjust synchronization parameters in real-time. This closed-loop control ensures optimal synchronization accuracy while minimizing latency throughout the audiovisual content sharing session.
2Adaptability or versatility
If multiple devices are used for audiovisual content generation and sharing, then content collaboration capability is improved, but system complexity increases due to need for packet synchronization and echo cancellation across devices
Solution Approach 1:
The system introduces a central coordinator device that acts as an intermediary, managing packet synchronization and echo cancellation for all participating devices. This mediator consolidates the complexity of multi-device coordination into a single point of control, allowing multiple devices to share audiovisual content collaboratively without each device needing to implement complex synchronization logic.
3Productivity
If real-time audiovisual content is transmitted across network devices, then user-generated content sharing is enabled, but packet synchronization difficulties cause playback desynchronization
Solution Approach 1:
The system performs preliminary clock synchronization and establishes timing reference protocols before real-time audiovisual content transmission begins. This pre-synchronization ensures that all devices operate from a common time reference, enabling accurate packet synchronization during high-speed real-time content sharing without playback desynchronization.
