    摘要: An SVC encryption apparatus includes: an encoding/encryption unit for performing SVC (Scalable Video Coding) encoding on input data contents and carrying out encryption for data in accordance with a first encryption condition to generate a corresponding SVC bitstream; and a NAL (Network Adaptation Layer) data analysis unit for analyzing NAL data of the generated SVC bitstream to find out NAL data satisfying a second encryption condition. Further, the SVC encryption apparatus includes a conditional NAL data encryption unit for encrypting the extracted NAL data in accordance with the second encryption condition; and a bitstream transmitting unit for transmitting the SVC bitstream with encrypted NAL data.
