Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video streaming technologies face challenges in dynamically streaming high-resolution videos from drones using 5G networks, particularly due to fluctuating bandwidth and network interference, which can lead to unstable video transmission and control issues.
Innovation Solution
The method involves a video streaming apparatus and a mobile terminal that utilize geometry information, such as location and altitude data from GPS and sensors, to dynamically adjust the bitrate of video streams. This is achieved by referencing a bandwidth table that correlates location information with available bandwidth, allowing for real-time adjustments to ensure stable streaming and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-resolution video streaming is implemented using 5G networks, then video quality is improved, but network traffic overload and interference occur
Solution Approach 1:
The patent implements dynamic bitrate adjustment based on real-time location information. The system transitions from static fixed-bitrate streaming to dynamic adaptive streaming, where the bitrate is continuously adjusted according to the drone's position and network conditions. This allows the system to optimize video quality while preventing network overload by reducing bitrate when necessary.
Solution Approach 2:
The patent changes the bitrate parameter dynamically based on location information. By referencing a bandwidth table that correlates location data with available bandwidth, the system adjusts the video bitrate parameter in real-time. This parameter change enables the system to maintain high video quality when network conditions permit while reducing bitrate to avoid overload when conditions deteriorate.
2Ease of operation
If fixed resolution video streaming is used, then control is simplified, but adaptability to network conditions is reduced
Solution Approach 1:
The patent introduces dynamic resolution adjustment capability while maintaining a structured control approach. The system automatically adjusts resolution based on location and network conditions without requiring complex manual intervention. This dynamic adaptation maintains ease of operation through automated decision-making while significantly improving adaptability to varying network conditions.
3Productivity
If multiple drones stream simultaneously, then search efficiency is improved, but network interference increases
Solution Approach 1:
The patent applies local quality adjustment by tailoring the video bitrate to each drone's specific location conditions. Instead of using uniform high-bitrate streaming for all drones, the system adjusts each drone's bitrate based on its local network environment and position. This allows multiple drones to stream simultaneously with optimized quality levels, reducing mutual interference while maintaining search efficiency.
