Optical Securing Datum for Secure Remote Video Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video systems used for remote control of guided vehicles face challenges in ensuring the reliability and security of image transmission, as errors can occur during processing, transmission, or display, leading to discrepancies between the image captured by the camera and the image displayed remotely, which can compromise safety, especially in critical operations like rail transport.
Innovation Solution
The method involves generating an optical securing datum that is superimposed onto the image captured by the camera, creating a secure optical image which is then converted into a video signal, allowing for real-time verification of image integrity and conformity between the captured and displayed images, using an optical securing data generator and detection device to ensure the image displayed remotely matches the original image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video signals are transmitted through complex electronic systems with multiple components, then remote control functionality is enabled, but the reliability of image transmission deteriorates due to potential errors and malfunctions in each component
Solution Approach 1:
The patent applies preliminary action by generating an optical securing datum and superimposing it onto the optical image before the image is captured by the photosensitive receiver. This securing datum is embedded in advance into the video signal, allowing verification of image integrity before transmission occurs. The securing mechanism is prepared and integrated into the imaging process beforehand, preventing potential tampering or errors rather than detecting them after transmission.
Solution Approach 2:
The patent implements feedback by detecting the optical securing datum in the received video signal and verifying whether it matches the originally embedded datum. This creates a closed-loop verification system where the received image is compared against the expected securing datum, providing real-time feedback on transmission integrity. If discrepancies are detected, the system can identify and correct errors or reject compromised images.
2Productivity
If image processing operations such as compression, filtering, and encoding are applied, then transmission efficiency is improved, but image integrity deteriorates due to potential distortion and loss of original image data
Solution Approach 1:
The optical securing datum is embedded onto the optical image before any processing operations such as compression, filtering, or encoding are applied. This ensures that the securing datum is present in the original unprocessed image data, allowing verification of integrity even after subsequent processing. The securing mechanism is established beforehand, creating a reference point that remains valid through all transmission and processing stages.
Solution Approach 2:
The optical securing datum acts as an intermediary element that bridges the original image and the processed transmitted signal. It serves as a verification marker that survives through compression and encoding processes, allowing the receiver to authenticate that the processed image maintains fidelity to the original. The securing datum mediates between the need for efficient processing and the requirement for integrity verification.
3Adaptability or versatility
If the video transmission network is used with variable transmission time, then network flexibility is improved, but image accuracy deteriorates due to jitter causing replication or removal of video signal parts
Solution Approach 1:
The patent employs feedback by detecting and verifying the optical securing datum in the received video signal after transmission through the variable-time network. This verification process provides real-time feedback on whether jitter or timing variations have caused replication or removal of image parts. The securing datum serves as a reference that reveals any distortions introduced by network timing variations, allowing the system to identify and correct accuracy issues.
Solution Approach 2:
The securing datum is embedded into the video signal before transmission through the network with variable transmission time. This preliminary embedding creates a stable reference marker that remains intact despite timing variations and jitter during transmission. The securing mechanism is established beforehand, providing a means to verify image accuracy even after the signal has been subjected to network timing variations.
