Abstract
Watermarking and Encryption are commonly technique for data protection. DMB contents are utilized widely without protection procedure. To solve the problems, we propose real-time watermarking and encryption method for DMB contents protection in this paper. To implement watermarking, we hide key information on a redundant space of program association table (PAT) and program mapped table (PMT) of T-DMB stream and hidden parts is encrypted by a stream encryption cipher. We implements encryption method without additional information in digital multimedia broadcasting (DMB) contents using AES (advanced encryption standard) encryption algorithm. In experimental result, when we implemented a play control on PMP which have built-in DSP device to get 100Mhz processing speed, almost had not a time delay and the hiding information in T-DMB stream was possible to do a play control. Additionally, we confirmed that the saved contents in a PMP were not played in other devices without decryption key. The proposed methods can be useful in real-time applications requiring contents protection service such as video on demand, IPTV and digital TV.
