Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 3D video content is transmitted with high depth quality, then user experience is improved, but bandwidth consumption increases
Solution Approach 1:
The system dynamically adjusts the depth parameter of 3D video content based on real-time network conditions and device capabilities. The depth parameter can be modified during the video call to optimize the balance between video quality and bandwidth consumption, allowing the system to adapt to changing conditions without manual intervention.
Solution Approach 2:
The patent changes the depth parameter of the 3D video content to control the amount of data transmitted. By adjusting this parameter, the system can reduce the quantity of video data when bandwidth is limited, or enhance depth quality when sufficient bandwidth is available, directly addressing the contradiction between video quality and bandwidth consumption.
2Reliability
If depth parameter is increased for better 3D effect, then immersive experience is improved, but data transmission efficiency deteriorates
Solution Approach 1:
The system dynamically adjusts the depth parameter based on real-time assessment of network conditions and device capabilities. When network conditions are favorable, the depth parameter is increased to enhance immersive experience. When bandwidth is constrained, the depth parameter is reduced to maintain data transmission efficiency, allowing the system to optimize both metrics under different conditions.
Solution Approach 2:
The patent modifies the depth parameter of the 3D video content to control the trade-off between immersive experience and data transmission efficiency. By changing this parameter, the system can reduce the complexity and data requirements of the video stream when transmission efficiency is prioritized, or enhance the 3D effect when immersive experience is the primary goal.
3Productivity
If adaptive depth adjustment is implemented, then bandwidth efficiency is improved, but system complexity increases
Solution Approach 1:
The system implements a feedback mechanism where the receiver assesses network conditions and device capabilities, then communicates this information back to the transmitter. The transmitter uses this feedback to automatically adjust the depth parameter, optimizing bandwidth efficiency without requiring complex manual configuration or user intervention. This feedback loop simplifies the overall system complexity by automating the adaptation process.
Solution Approach 2:
The system enables automatic adaptation to network conditions and device capabilities without requiring manual configuration or user intervention. The depth parameter is self-adjusted based on real-time conditions, reducing the operational complexity for users while maintaining high bandwidth efficiency. The system serves itself by automatically optimizing parameters based on environmental feedback.

AI summary
In a first example, a processing system may transmit one or more reception parameters for a video call, where the one or more reception parameters include a first depth parameter defining a first depth of video content that the processing system is to display. The processing system may then receive the video content in accordance with the first depth parameter and present the video content in accordance with the first depth parameter. In a second example, a processing system may detect a bandwidth constraint for a transmission of video content for a video call, select a first depth parameter based upon the bandwidth constraint, and transmit a video stream comprising the video content in accordance with the first depth parameter.
