Today's omnipresent demand for access to multimedia content via diverse devices places new challenges on efficient content delivery. While the Scalable Video Coding (SVC) extension of Advanced Video Coding (AVC) has proven to be a useful tool for the advanced delivery of video content, it has not yet found major adoption in practice. This paper introduces the concept of SVC tunneling developed in the EU FP7 ALICANTE project, which attempts to provide device-independent access to media resources at reduced network load. For SVC tunneling, video transcoding is performed at the ingress/egress points of the network, which may impact the video quality. We show that the quality impact of these transcoding steps for a transcoding chain from MPEG-2 to SVC and back to MPEG-2 accumulates to a PSNR reduction of up to 2.1 dB for transcoding at fixed target bitrates. We also discuss research challenges and open issues in SVC tunneling.

“…We can see that there are mainly two modules in the system: available bandwidth measurement module (ABWM module) and scalable video coding module (SVC module) [13]. Video data is encoded by the SVC module and then sent to the network according to the current measurement result of the ABWM module.…”

In recent years, M2M networking is an active research topic in both academic and industrial fields. Home M2M networks, as an important branch of M2M networks, have attracted wide concerns for home application. In this paper, we first present a brief overview of home M2M networks. Then we introduce a hierarchical architecture of home M2M networks and describe the approach of devices management and services discovery. After that, we focus on the security authentication with centralized node and an improved method of available bandwidth measurement. With the centralized node, our system is more efficient and secure, because of efficient resource management and users' anonymity protection. Compared to existing bandwidth measurement methods, our method takes up less additional bandwidth, saves more time, and has a higher accuracy for measurement. Experiments are carried out to demonstrate the effectiveness and accuracy of the proposed scheme.

“…No entanto as extensões escaláveis do MPEG-2 nunca obtiveram aceitação suficiente devido a grandes perdas na compressão, se comparadas a versões não escaláveis. Isso mudou com a padronização H.264/MPEG-4 Scalable Video Coding (SVC) (Amon et al, 2008).…”

“…Para a escalabilidade espacial o padrão SVC segue a abordagem de codificação multi-camadas, tambem utilizada no MPEG-2 Video/H.262, H.263 e no MPEG-4 Visual (Amon et al, 2008). Cada camada corresponde a uma resolução espacial e é nomeada com um identificador de dependência, sendo zero para a primeira, aumentando em uma unidade para cada camada adicional.…”
