发明名称 METHOD FOR INSERTING SYNCHRONIZATION MARKS IN A VIDEO STREAM, COMPATIBLE WITH BLOCK ENCRYPTION
摘要 The invention concerns a method for inserting synchronization marks (200) in a standardized stream of compressed and encrypted data, which consists in encrypting bit by bit one part at least of a stream of compressed data, by block encryption, and which consists in inserting a synchronization mark in the stream only after the number of encrypted bits reaches or exceeds the number of bits of the encryption block.
