Surgical Video Quality Control via Bandwidth Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cloud-based surgical video distribution, there is a trade-off between video quality and real-time property, making it challenging to maintain high-quality video transmission while ensuring real-time instruction during remote surgeries.
Innovation Solution
An information processing method that controls the quality of surgical videos based on the user's selection status and communication line status, allowing high-quality transmission of selected videos while reducing the quality of non-selected videos to maintain real-time property.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If video quality is reduced to maintain real-time property, then real-time transmission is improved, but video quality deteriorates
Solution Approach 1:
The patent applies local quality by transmitting different quality levels for different video streams simultaneously. The selected surgical video is transmitted at high quality, while non-selected videos are transmitted at reduced quality or omitted entirely. This allows the system to maintain real-time transmission for all streams while preserving high quality for the most important video content.
Solution Approach 2:
The system dynamically changes transmission parameters including quality level, resolution, and frame rate based on real-time conditions. When a video is selected, its transmission parameters are optimized for high quality; when not selected, parameters are reduced to maintain real-time performance. This dynamic parameter adjustment resolves the contradiction between quality and speed.
2Manufacturing precision
If high-quality surgical videos are transmitted to maintain instructional accuracy, then video quality is improved, but network bandwidth consumption increases
Solution Approach 1:
The patent implements local quality by applying different quality levels to different video streams based on their importance. The selected surgical video receives high-quality transmission to ensure instructional accuracy, while non-selected videos are transmitted at lower quality or excluded from transmission. This selective quality approach optimizes bandwidth utilization while maintaining necessary video quality.
Solution Approach 2:
The system transmits only the necessary portion of video content at high quality - specifically, only the selected surgical video that the instructor needs to view. Other videos are transmitted at reduced quality or not at all, representing a partial action that suffices for the instructional purpose while conserving network bandwidth.
3Loss of information
If multiple surgical videos are transmitted simultaneously, then information completeness is improved, but system complexity increases
Solution Approach 1:
The patent segments the video transmission system into multiple independent streams, each with its own quality control parameters. The transmission control unit divides and manages multiple video streams separately, allowing selective quality adjustment for each stream based on instructor selection. This segmentation enables comprehensive information transmission while simplifying quality management through individualized control of each video stream.
Solution Approach 2:
The system dynamically adjusts the transmission parameters of multiple video streams based on real-time instructor selections. When the instructor selects a particular video, the system dynamically changes the quality and priority of that stream relative to others. This dynamic adaptation allows the system to maintain information completeness while managing complexity through flexible, condition-based parameter adjustment.
