Innovation Solution
An interaction method and system utilizing a real-time audio and video cloud service interface combined with the User Datagram Protocol (UDP) for creating consultation groups, enabling secure and efficient transmission of high-definition audio and video streams between patients and doctors, with features like packet loss compensation to ensure reliable communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If real-time audio and video cloud service interface is used for remote consultation, then audio and video quality is improved, but network stability and transmission reliability deteriorate due to unstable network conditions
Solution Approach 1:
The patent implements packet loss compensation mechanisms and retransmission protocols before communication failures completely degrade the consultation quality. Buffer zones and error correction codes are pre-configured to cushion against network instability, allowing high-definition audio and video transmission to maintain reliability despite fluctuating network conditions.
Solution Approach 2:
The system dynamically adjusts transmission parameters such as bitrate, resolution, and frame rate based on real-time network conditions. When network stability deteriorates, the system automatically modifies these parameters to maintain both audio and video quality and transmission reliability, resolving the contradiction between high fidelity and stable delivery.
2Measurement precision
If high-definition audio and video data is transmitted, then consultation accuracy is improved, but network resource consumption and cost increase
Solution Approach 1:
The patent employs dynamic adaptive streaming technology that continuously monitors network resource availability and adjusts the audio and video data transmission quality accordingly. This allows the system to maintain consultation accuracy when resources are abundant while reducing network resource consumption during periods of limited bandwidth, effectively resolving the contradiction between high definition quality and resource efficiency.
Solution Approach 2:
The system implements selective transmission where only the necessary portion of audio and video data is sent at high definition quality. Non-critical visual elements or audio frequencies less important for medical diagnosis are transmitted at lower quality, maintaining consultation accuracy for essential medical information while reducing overall network resource consumption.
3Productivity
If real-time interaction is implemented, then consultation efficiency is improved, but latency and response time increase due to network conditions
Solution Approach 1:
The patent divides audio and video data into smaller packets with optimized transmission priorities. Critical real-time interaction data such as audio signals and key video frames are segmented and transmitted with higher priority to reduce latency, while less time-sensitive data follows. This segmentation allows the system to maintain consultation efficiency by ensuring that the most important real-time interactions experience minimal delay despite network conditions.
