Video Processing Device Security Information Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital video protection technologies, such as DRM, are vulnerable to infringement when the security measures are bypassed by crackers or hackers, allowing unauthorized sharing and reproduction of copyrighted content.
Innovation Solution
A video processing device and method that inserts security information, including reproduction rights, into the video's header or payload, and applies digital rights management, allowing only authorized devices to reproduce specific portions of the content, thereby enhancing security and restricting access based on set rights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If DRM technology is applied to protect video content, then copyright security is improved, but the system complexity increases
Solution Approach 1:
The video stream is segmented into multiple packets, and security information is inserted into specific packets rather than the entire stream. This allows selective protection of content portions, reducing the complexity burden across the whole system while maintaining security effectiveness.
Solution Approach 2:
A dedicated security information insertion mechanism acts as an intermediary between the encoding process and the content delivery. This intermediary component handles the complexity of rights management independently, allowing the main video processing system to remain simpler while still achieving secure distribution.
2Reliability
If security information is inserted into video packets, then content protection is improved, but the data size increases
Solution Approach 1:
Security information is inserted locally into specific packets where it is most needed, rather than adding protection uniformly across the entire video stream. This allows the system to protect critical content portions while minimizing the overall data size increase.
Solution Approach 2:
Instead of providing comprehensive security information for all content, the system applies security measures partially to key packets and content segments. This partial action approach maintains effective protection while avoiding the excessive data overhead that would result from full-stream encryption and protection mechanisms.
3Reliability
If reproduction rights are restricted based on device level, then copyright enforcement is improved, but the ease of operation decreases
Solution Approach 1:
The video reproducing device automatically checks the security information and reproduction rights embedded in the packets without requiring user intervention. The device self-verifies its authorization status and automatically decides whether to reproduce the content, eliminating the need for manual rights verification while maintaining strong copyright enforcement.
Solution Approach 2:
The system changes the operational parameters of the reproducing device by embedding rights information directly into the video stream packets. This allows the device to automatically adjust its reproduction behavior based on the embedded rights parameters, making the copyright enforcement process transparent to the user while maintaining ease of operation.
