AI Technical Summary
Technical Problem
Existing encryption technologies for high-definition media like Blu-ray discs are complex and time-consuming, leading to increased cost and reduced response times for playback devices, making them impractical for widespread consumer use.
Method used
A playback method for encrypted video information that uses a system stream file with segments decrypted by different keys, allowing conversion to a post-conversion stream with invalid packets to maintain compatibility with conventional decoders, reducing processing load and cost.
Benefits of technology
This approach enables the use of conventional decoders without redesign, minimizing implementation load and cost while ensuring efficient playback of encrypted high-definition content.
