Intelligent digital TV (iDTV) is a future digital TV with intelligence which can automatically provide userpersonalized services for each audience. For the userpersonalized services, the iDTV should recognize audiences in real-time. In this paper, we define a novel structure of the iDTV and propose a real-time person identification system in the iDTV that(More)
Recently, there is an active research about a new emerging video coding standard, scalable video coding (SVC). SVC adopts a layered coding scheme to generate multi-layered bitstream for heterogeneous environments. In addition to the layered coding, SVC performs temporal prediction using the hierarchical B picture scheme in order to provide temporal scalable(More)
In this paper, we propose a new encryption method for copyright protection of MP3 and MPEG-4 coder. For the MP3 audio, the magnitude and phase information of modified discrete cosine transform (MDCT) coefficients is encrypted. DCT coefficients and motion vectors (MVs) are used for the encryption of the MPEG-4 video. Experimental results indicate that the(More)
