Bandwidth Dependent Media Stream Compression for Tactical Medical Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Virtual Interactive Presence and Augmented Reality (VIPAR) systems for medical assistance in battlefield scenarios are hindered by the need for expensive hardware, high-bandwidth networks, and complex setup, making them unsuitable for tactical environments where low-bandwidth and high-latency networks prevail.
Innovation Solution
A system that captures a media stream from a central device, removes the background environment to transmit only the moving object, adjusts data transmission based on network bandwidth, and synchronizes the stream with the original media on a field device, allowing for efficient and effective video streaming over low-bandwidth networks without requiring specialized hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If full media stream with background environment is transmitted, then visual quality is improved, but bandwidth consumption increases
Solution Approach 1:
The patent extracts and removes the background environment from the media stream, transmitting only the moving object (foreground). This extraction process reduces the quantity of data transmitted while preserving the essential visual information needed for medical guidance, directly resolving the contradiction between visual quality and bandwidth consumption
Solution Approach 2:
The media stream is segmented into background environment and moving object components. By separating these elements and transmitting only the necessary moving object portion, the system achieves efficient bandwidth utilization while maintaining adequate visual quality for medical assistance purposes
2Measurement precision
If high-fidelity video streaming is implemented, then diagnostic accuracy is improved, but network bandwidth requirements increase
Solution Approach 1:
The system applies local quality by focusing transmission resources on the moving object (foreground) where diagnostic information is located, rather than uniformly transmitting the entire scene. This selective quality distribution maintains diagnostic accuracy for critical elements while reducing overall bandwidth consumption
3Loss of information
If background environment is included in transmission, then contextual information is improved, but data transmission volume increases
Solution Approach 1:
The background environment is extracted and removed from the transmission stream. While this reduces contextual information, it preserves the essential moving object data needed for medical guidance, achieving an optimal balance between information retention and transmission efficiency in bandwidth-constrained tactical environments

AI summary
In general, this disclosure describes media stream transmission techniques for a computing device. The computing device may capture an image of a local background environment. The computing device may record a first media stream that includes at least a portion of the image of the background environment and at least one movement of at least one object through the background environment. The computing device may remove the image of the background environment from the first media stream to create a second media stream that includes the movement of the object without the image of the background environment. The computing device may determine a bandwidth of a network over which the second media stream will be transmitted and perform further alterations to the second media stream if the current bandwidth is less than a bandwidth threshold level in order to reduce the bandwidth needed to transmit the second media stream.
