Abstract:A kind of encryption terminal using TMS320DM6446 is designed in this paper. Considering the structure of H.264 bit-stream, the policy of selected video encryption based on H.264 Data Partition Mode (DPM) is presented. The hardware and software design of the terminal is described. The experimental results show that the system can encrypt real-time H.264 video stream in CIF mode with a lower complexity.
Keywords:H  264  TMS320DM6446
