摘要：
A method for encoding MPEG compatible video data for subsequent compression comprises detecting a plurality of frames of video data organized as a GOP, generating an encryption key for the GOP, and encrypting the video data using GOP-synchronized substitution, transposition, and rotation transformations that are parameterized by offsets derived from the generated encryption key.
