Optical Discs TRIZ Cases
- Optical Disc Address Coding to Block Incorrect Format Detection
Bit inversion in Reed-Solomon-coded address data forces detectable errors, preventing wrong address reads on incompatible optical disc formats.
- Header-Corrected EDC Circuit for Lower Optical Disc Bandwidth
By generating EDC from main data first and correcting it with the header, this circuit cuts optical disc memory bandwidth and access time.
- Shared ECC Engine for Multi-Standard Optical Disc Processing
A shared error correction engine consolidates syndrome generation and erasure detection to reduce hardware complexity across multiple optical disc standards.
- Smart Object Security for Media Storage Decryption
A smart object attached to media storage holds decryption keys accessible only by a dedicated reader, preventing unauthorized copying of encrypted content.
- Optical Recording Device Multi-Channel Synchronization
A distribution control unit allocates data blocks to multiple recording channels based on transfer time calculations.
