Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote controlled devices with cameras face issues such as non-dedicated camera mounting, balance during operation, and high latency in wireless image transfer, especially when the camera is moving at variable speeds.
Innovation Solution
A system and method that includes receiving images or video frames at a wireless receiver interface, performing decoder nudging, overclocking the display frequency, and outputting decoded frames to reduce latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If standard decoding and display operations are used, then the system is simple to operate, but the latency in image transfer is high
Solution Approach 1:
The patent applies preliminary action by performing decoder nudging, which pre-adjusts the decoding process to anticipate and prepare for incoming video frames. This proactive adjustment reduces the processing time when frames actually arrive, thereby reducing latency without requiring a complete overhaul of the decoding architecture.
Solution Approach 2:
The patent implements dynamics by overclocking the display frequency dynamically. Instead of using a fixed display rate, the system increases the display frequency beyond standard rates to accelerate the presentation of decoded frames, thus reducing the time from capture to display while adapting the system's operational parameters in real-time.
2Adaptability or versatility
If the camera moves at variable speeds, then the system is adaptable to different flight conditions, but the latency in wireless image transfer increases
Solution Approach 1:
The patent ensures continuity of useful action by maintaining an optimized pipeline where decoder nudging continuously prepares the decoding stage and overclocked display continuously presents frames at maximum rate. This continuous optimization ensures that regardless of the camera's motion state or speed variations, the system consistently operates at peak efficiency to minimize latency throughout the entire video capture and display process.
