Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If videoconference signals are converted to analogue format for encoding, then compatibility with existing encoding systems is improved, but quality and accuracy losses occur due to digital-to-analogue and back-to-digital conversions
Solution Approach 1:
The patent extracts the encoding function from the videoconference equipment itself and separates it into a dedicated encoding system that receives digital signals directly over the network. This eliminates the need for analogue conversion while maintaining compatibility with existing encoding workflows and software players.
Solution Approach 2:
The patent introduces an intermediary encoding system that acts as a bridge between the videoconference equipment and the final output devices. This intermediary receives digital signals directly from the videoconference system via network protocols and performs encoding without analogue conversion, thus preserving signal quality while enabling compatibility with various playback devices.
2Adaptability or versatility
If additional encoding computer system is introduced to stream to observers, then accessibility for non-participants is improved, but device complexity and setup requirements increase
Solution Approach 1:
The patent makes the videoconference equipment itself multi-functional by enabling it to perform encoding operations directly. The same videoconference system that supports participant interaction can also generate streams for observers without requiring separate dedicated encoding hardware, thus reducing overall system complexity while maintaining accessibility.
Solution Approach 2:
The patent merges the encoding function with the videoconference equipment by implementing software-based encoding within the existing system architecture. This consolidation eliminates the need for separate physical encoding computers and reduces the number of devices that need to be configured and maintained, while still providing streaming capability to observers.
3Manufacturing precision
If high bandwidth is used for videoconference transmission, then audio visual quality is improved, but network resource consumption and bandwidth requirements increase
Solution Approach 1:
The patent implements dynamic encoding that adjusts compression parameters based on network conditions and content characteristics. The system can vary bitrates, resolution, and frame rates in real-time to optimize the balance between audio visual quality and bandwidth consumption, allowing high quality transmission when bandwidth is available and efficient compression when bandwidth is limited.
Solution Approach 2:
The patent changes encoding parameters such as bitrate, resolution, and compression level based on the specific content being transmitted and the target observer's capabilities. By adapting these parameters dynamically, the system maintains high audio visual quality where possible while reducing bandwidth consumption for less critical content or when network conditions dictate.

AI summary
The present invention relates to a method, system and apparatus for encoding audio visual media signals sourced from preferably a video conference transmission. The technology provided is adapted to receive a video conference transmission from a computer network where this video conference transmission includes at least one audio visual signal and at least one protocol signal. One or more protocol signals are then read from the transmission received with the technology provided applying a selected encoding process to a received audio visual signal, wherein the encoding process selected depends on the contents of a read protocol signal.
