Interlaced Thermal Video Data Transmission via Frame Subsetting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Processing and transmitting thermal video data and scene data simultaneously can be bandwidth-intensive, as most scene data may not be as relevant as video data, leading to increased processing time and resource usage without compromising accuracy and completeness.
Innovation Solution
A method and system that interlace and transmit thermal data at a lower frame rate than video data, using a subset of temperature frames and correlating missing data with video frames to reconstruct full thermal data, reducing the amount of data transmitted while maintaining accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If thermal data and video data are transmitted at the same frame rate, then data completeness is improved, but bandwidth consumption increases
Solution Approach 1:
The patent segments thermal data transmission by selecting a subset of temperature frames (e.g., every Nth frame) to be transmitted alongside video frames. This segmentation reduces the total volume of thermal data transmitted while maintaining sufficient information for reconstruction purposes
Solution Approach 2:
The patent transmits only a partial set of thermal data frames rather than all frames. By transmitting a subset of temperature frames at a lower rate than video frames, the system achieves sufficient thermal information for most applications without the full bandwidth cost of transmitting every thermal frame
2Quantity of substance
If thermal data is transmitted at a lower frame rate, then bandwidth requirements are reduced, but data accuracy may be compromised
Solution Approach 1:
The patent uses video frame data as feedback to guide the reconstruction of missing thermal data frames. By correlating video frame information with the subset of transmitted thermal frames, the system can intelligently reconstruct full thermal data sequences, maintaining accuracy while using reduced bandwidth
Solution Approach 2:
The patent creates reconstructed copies of missing thermal data frames by correlating information from video frames and the subset of transmitted thermal frames. This copying approach allows the system to recover full thermal data accuracy without transmitting every original thermal frame
3Loss of information
If all scene data is transmitted with video data, then data completeness is improved, but processing time increases
Solution Approach 1:
The patent extracts and transmits only the most essential thermal data frames (a subset of temperature frames) alongside the video stream, leaving out redundant frames that can be reconstructed later. This extraction approach reduces processing time while maintaining sufficient scene data completeness

AI summary
Methods of and systems for providing temperature data in a video stream are provided. The method includes receiving a video stream having a plurality of video frames with a first frame rate and receiving temperature data including a temperature map associated with the video stream and having a plurality of temperature frames with a second frame rate, which can be slower than the first frame rate. To interlace the temperature data, a subset of temperature frames in the plurality of temperature frames can be extracted. The method further includes transmitting each temperature frame in the subset of temperature frames with the plurality of video frames in a data stream.
