In IoT environments, existing technologies face challenges in enhancing the quality of experience (QoE) during screen sharing between multiple terminals due to inefficiencies in transmitting screen images, leading to suboptimal performance and network congestion.
Innovation Solution
A method and apparatus utilizing a relay device to receive and transmit screen images between terminals, determining encoding quality based on performance information and network status to optimize bit rate, frame rate, and resolution, thereby selecting the most suitable relay device to ensure high-quality screen sharing within allowed network ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If screen images are transmitted directly between terminals without a relay device, then transmission speed is faster, but network congestion occurs and quality of experience deteriorates
Solution Approach 1:
A relay device is introduced as an intermediary between the first terminal and second terminals. The relay device receives screen images from the first terminal, determines appropriate encoding quality based on performance information and network status, encodes the images, and then transmits them to the second terminals. This intermediary approach manages network traffic more effectively, preventing congestion while maintaining transmission speed and improving overall quality of experience.
2Manufacturing precision
If encoding quality is increased to improve image quality, then quality of experience is improved, but network bandwidth consumption increases
Solution Approach 1:
The encoding quality parameters (bit rate, frame rate, resolution) are made dynamic rather than fixed. The relay device continuously monitors performance information from the first terminal and network status, then adjusts encoding quality in real-time. This dynamic adaptation allows the system to optimize image quality while consuming only the necessary network bandwidth, preventing waste while maintaining high quality where needed.
Solution Approach 2:
The system changes encoding parameters (bit rate, frame rate, resolution) based on current conditions. By adjusting these parameters dynamically according to performance information and network status, the system achieves optimal balance between image quality and bandwidth consumption, improving quality of experience without excessive resource usage.
3Reliability
If relay device selection is made dynamically based on performance and network status, then quality of experience is optimized, but device complexity increases
Solution Approach 1:
The relay device selection mechanism uses feedback from performance information and network status to dynamically select the most appropriate relay device. This feedback-driven approach ensures optimal quality of experience by choosing relays that can handle current traffic conditions, while the automated nature of the feedback loop prevents excessive complexity in manual configuration and management.
