Dynamic Tile Division for High-Resolution Video Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current imaging systems face inefficiencies in distributing high-resolution videos when there is a significant difference between the captured area and the user-designated observation area, leading to bandwidth and resource burdens due to the need to transmit multiple tile videos or generate a new video from tile groups.
Innovation Solution
An imaging system that dynamically adjusts the tile division method based on the user's observation area designation frequency, allowing for efficient distribution of the desired resolution by switching between reference tile configurations and tile compositions to minimize bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple tile videos are transmitted to the user to achieve high resolution in a designated area, then video quality is improved, but bandwidth consumption increases
Solution Approach 1:
The video is divided into multiple tile videos, allowing the system to transmit only the specific tiles corresponding to the user's designated observation area rather than the entire video, thus reducing bandwidth consumption while maintaining high resolution in the area of interest
Solution Approach 2:
The system applies different quality levels to different regions of the video by transmitting multiple tiles at high resolution only for the designated observation area, while other areas may use lower resolution, optimizing the trade-off between video quality and bandwidth usage
2Manufacturing precision
If a video is divided into a large number of tile areas to maintain high resolution, then video quality is improved, but device complexity increases
Solution Approach 1:
The system dynamically adjusts the tile division method based on the size and position of the user's designated observation area. When the designated area is small, fewer tiles are transmitted; when it is large, more tiles are transmitted. This dynamic adaptation reduces unnecessary system complexity while maintaining high resolution where needed
3Ease of operation
If the client side cuts out and enlarges an area from the video, then the desired observation area is achieved, but effective resolution decreases
Solution Approach 1:
The video is pre-divided into multiple tile areas on the server side before transmission. When the user designates an observation area, the system can directly assemble and transmit the corresponding high-resolution tiles without requiring the client to perform cutting and enlargement operations, thus preserving effective resolution
