Video Reception Switching After Tampering Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video data tampering detection systems fail to ensure the reception of untampered video data after detection of tampering, leading to potential loss of untampered data.
Innovation Solution
A video reception apparatus and transmission apparatus equipped with processors and memory to implement a method for determining tampering and switching to a different communication method upon detection, along with recording and changing recording settings to protect untampered data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video data is transmitted using a single communication method with tampering detection, then tampering can be detected, but untampered video data cannot be received afterward
Solution Approach 1:
The system changes the communication method parameter when tampering is detected. Specifically, it switches from the first communication method to a second communication method, thereby altering the transmission parameters to prevent further tampering while maintaining video reception continuity
Solution Approach 2:
The communication method is made dynamic rather than static. The system can adaptively switch between different communication methods based on tampering detection results, allowing the video reception system to respond to changing security conditions and maintain continuous reception of untampered data

AI summary
A video reception apparatus configured to communicate with a video transmission apparatus using at least a first method includes one or more processors, and one or more memories storing instructions that, when executed by the one or more processors, cause the one or more processors to function as a reception unit configured to receive video data via the communication using the first method, a determination unit configured to determine whether the received video data has been tampered with, and a transmission unit configured to transmit, to the video transmission apparatus, a command to start communication using a second method different from the first method in a case where the received video data is determined to have been tampered with.
