Multiple descriptions scalable video coding

by Christophe Tillier, Béatrice Pesquet-popescu, Mihaela Van Der Schaar - in Proceedings of the 12th European Signal Processing Conference (EUSIPCO ’04 , 2004
"... Multiple description coding (MDC) is a joint source-channel coding technique specifically designed for real-time multimedia applications over best effort switched packet networks (such as Internet), in order to cope with packet losses due to transmission errors or network congestion. Error resilienc ..."

ContentAdaptive Spatial Scalability for Scalable Video Coding

by Yongzhe Wang , Nikolce Stefanoski , Xiangzhong Fang , Aljoscha Smolic - Proc. PCS
"... ABSTRACT This paper presents an enhancement of the SVC extension of the H.264/AVC standard by content-adaptive spatial scalability (CASS). CASS introduces a novel functionality which is important for high quality content distribution. The video streams (spatial layers), which are used as input to t ..."
