摘要：In this method of access to a protected multimedia content, a descrambler: decrypts (120) a fragment of the multimedia content with a decryption key; replaces (134) a string of M consecutive original bits of the unscrambled fragment with a string of

N consecutive substituted bits, where N is strictly greater than M and the string of N substituted bits is different for each different string of M original bits; and stores (140) the fragment thus modified in a shared memory, and a decoder: extracts (150) the modified fragment from the shared memory; replaces (164) the substituted string of N bits with the string of M original bits; decodes (170) the unscrambled fragment thus reconstructed; and transmits (180) the decoded fragment to a multimedia apparatus able to play it.
