System and method for preventing an illegal copy of contents
InactiveUS7095853B2Difficult to reproduceTelevision system detailsKey distribution for secure communicationVariable-length codeVariable length
The method of preventing illegal copy of contents encrypts a header using a key generated from the previous sector, performs variable-length coding to the encrypted header to shorten its length, and stores the decoded header into the recording medium as well as contents data, in encryption phase. The method, in decryption phase, reproduces the contents data which have different length for each sector by decoding and encoding the header.
