Efficient In-Network Adaptation of Encrypted H.264/SVC Content

by Hermann Hellwagner, Robert Kuschnig, Thomas Stütz, Andreas Uhl , 2009
"... This paper addresses the efficient adaptation of encrypted scalable video content (H.264/SVC). RTP-based in-network adaptation schemes on a media aware network element (MANE) in an IPTV and VoD scenario are considered. Two basic alternatives to implement encryption and adaptation of H.264/SVC conten ..."

content are investigated: (i) full, format-independent encryption making use of Secure RTP (SRTP); (ii) SVC-specific encryption that leaves the metadata relevant for adaptation (NAL unit headers) unencrypted. The SRTP-based scheme (i) is straightforward to deploy, but requires the MANE

"... Abstract Taking advantage of the inter-layer prediction technique used in H.264/SVC (Scalable Video Coding), in this paper we propose an efficient block-based encryption scheme (BBES) for encrypting H.264/SVC enhance-ment layers. BBES operates in three modes, namely, Intra-MB mode, Group-MB mode and ..."

Secure Scalable Video Compression for GVid

by Heinz Hofbauer, Thomas Stütz, Andreas Uhl
"... Abstract. GVid is a Grid service that enables the secure and transparent integration and development of graphical user interface applications in the Grid. It separates the potentially computationally complex task of data creation and visualization, e.g., scientific simulations, from the comparably c ..."
