Method for decoding and apparatus for detecting watermarks watermarks in a bit stream of compressed video.

摘要

Method (500) for detecting a digital fingerprint embedded in a bit stream of compressed video, said method comprising: - reception (546) of the fingerprint as unique identification code with a binary sequence, wherein said method further comprises: - identification (552) of each bit of the unique identification code from the corresponding coded block of compressed video bitstream by comparing the binary value of the unique identification code to the parity of the number of coded coefficients of the corresponding block.
