Scheduling and resource allocation for SVC streaming over OFDM downlink systems
- IEEE Trans. Circuits and Systems for Video Tech
, 2009
"... Abstract—We consider the problem of scheduling and resource allocation for multiuser video streaming over downlink orthogonal frequency division multiplexing (OFDM) channels. The video streams are precoded using the scalable video coding (SVC) scheme that offers both quality and temporal scalabiliti ..."

, and transmission history. Simulation results show that the proposed algorithm outperforms the content-blind and deadline-blind algorithms with a gain of as much as 6 dB in terms of average PSNR when the network is congested. Index Terms—Multiuser, OFDM, resource allocation, SVC, video streaming.
Volume is not Enough: SVC-aware Server Allocation for Peer-assisted Streaming
"... Abstract—Peer-assisted delivery of video content has shown a great potential to reduce upload bandwidth requirements for content providers by exploiting idle client resources in the video dissemination process. As primary content sources, the servers run by content providers play a critical role in ..."

video content becomes relevant. The spreading of video blocks with the wrong quality can lead to situations where peers are forced to reduce their video qualities, despite them having enough download capacity. To address this problem, in this paper, a new SVC-based adaptation policy and a request
Efficient selective encryption with H.264/SVC CABAC bin-strings
- in Proc. of IEEE Int. Conf. on Image Processing
, 2012
"... The distribution of copyrighted scalable video content to differing digital devices should be protected during rendering and transmission. The proposed scheme is applied to H.264 Scalable Video Coding (SVC) CABAC bin strings in a compression-friendly and decoder format compliant manner. It achieves ..."

Downlink OFDM Scheduling and Resource Allocation for Delay Constraint SVC Streaming
"... Abstract—Efficient delivery of multimedia contents over wireless network is essential for future communication networks. However, content distribution and network engineering are traditionally studied separately, which leads to suboptimal network performance. In this paper, we consider the problem o ..."

Video Multicast over Wireless Mesh Networks with Scalable Video Coding (SVC)
"... We address the problem of rate allocation for video multicast over wireless mesh networks. An optimization framework is established to incorporate the effects of heterogeneity in wireless link capacities, traffic contention among neighboring links and different video distortion-rate (DR) characteris ..."

P2P VIDEO STREAMING COMBINING SVC AND MDC
"... Coding) video coding scheme for Peer-to-Peer (P2P) video multicast. The proposed scheme is based on a full cooperation established between the peer sites, which contribute their upload capacity during video distribution. The source site splits the video content into many small blocks and assigns eac ..."

each block to a single peer for redistribution. Our solution is implemented in a fully meshed P2P network in which peers are connected to each other via UDP (User Datagram Protocol) links. The video content is encoded by using the Scalable Video Coding (SVC) method. We present a flow control mechanism
H.264 SVC Complexity Reduction Based on Likelihood Mode Decision
