Scrambling high dynamic range videos: Scrambling HDR videos

摘要

In this paper, a scrambling technique is integrated in a HDR (High Dynamic Range) video. Specifically, the scrambling process will be directly applied to the DCT (Discrete Cosine Transform) coefficients after quantization and before entropy coding. Authorized users perform unscrambling (inverse scrambling) of the resulting coefficients of entropy decoding at the decoder side.
