Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If video resolution and frame rate are maintained at reference levels during streaming service, then image quality is preserved, but network bandwidth consumption increases causing quality degradation when traffic increases
Solution Approach 1:
The patent implements dynamic adjustment of video resolution and frame rate based on real-time network traffic conditions. The image processor monitors network traffic and dynamically signals the video service server to adjust transmission parameters, allowing the system to adapt between high quality (low traffic) and bandwidth efficiency (high traffic) modes seamlessly
Solution Approach 2:
The system changes key video parameters (resolution and frame rate) based on network conditions. When network traffic increases, the system transitions to lower resolution and/or lower frame rate to reduce bandwidth consumption, and vice versa, maintaining optimal balance between image quality and network efficiency
2Productivity
If video resolution is reduced in response to network traffic increase, then bandwidth consumption decreases, but perceived image quality degradation occurs
Solution Approach 1:
The system establishes a feedback loop where the image processor monitors network traffic conditions and provides real-time signals to the video service server. This feedback mechanism enables dynamic adjustment of video parameters based on actual network state, allowing the system to optimize bandwidth usage while minimizing visible quality degradation through intelligent parameter selection
Solution Approach 2:
The patent applies different quality levels to different aspects of video transmission based on network conditions. Instead of uniform quality degradation, the system selectively adjusts resolution and frame rate parameters to maintain acceptable perceived quality while reducing bandwidth consumption, effectively applying quality optimization locally to critical video attributes
3Productivity
If frame rate is reduced to manage network traffic, then data transmission volume decreases, but motion smoothness deteriorates
Solution Approach 1:
The system dynamically adjusts frame rate based on real-time network traffic monitoring. When network conditions deteriorate, the frame rate is reduced to lower data transmission volume, and when conditions improve, the frame rate is restored to maintain motion smoothness, creating a dynamic balance between bandwidth efficiency and visual quality

AI summary
An example display apparatus includes a communicator configured to receive video content from a video service server through a network and transmit data to the video service server; an image processor configured to decode the video content and output an image frame; and an image display on which the image frame is displayed, wherein the image processor transmits one of a video resolution reduction signal for allowing the video service server to transmit video content having a resolution lower than a reference resolution in response to an increase in traffic of the network and a frame rate reduction signal for allowing the video service server to transmit video content having a frame rate lower than a reference frame rate in response to an increase in traffic of the network.
