Secured MPEG-21 digital item adaptation for H.264 video


Seamless adaptation and transcoding techniques to adapt the digital content have achieved significant focus to serve the consumers with the desired content in a feasible way. With the succession of time we sense that secured adaptation should also be taken care of for not only serving sensitive digital contents but also to offer security as an embedded feature of the adaptation practice to ensure digital right management and confidentiality. In this paper, we propose an encryption framework for a transcoder while adapting H.264 video conforming to MPEG-21 DIA. Encryption mechanism is applied on the adapted video content thus reducing computational overhead compared to that on the original content. © 2006 IEEE.
