Peer-to-Peer networks are widely used in media transmission because of its excellent network scalability. Scalable media service is proposed to adapt to different terminal processing abilities. For stratified characteristics of progressive meshes, scalable video, this paper propose a kind of P2P progressive transmission based on multiple implied tree cover. It makes use of several implied tree cover...
The efficient scheduling of streaming data delivery in a peer-to-peer (P2P) network is a hard problem due to the Internet's lack of support for resource allocation and performance guarantees. In particular, the bandwidth resources available to a peer is constantly in flux and the future bandwidth availability is very difficult, if not impossible, to predict accurately. This work proposes to tackle...
Current peer-to-peer (P2P) swarming systems have been immensely successful for large scale media content distribution with fewer server resources and lower protocol overhead. In order to improve media delivery quality and provide high service availability, network coding techniques have been proposed to help resource propagating through P2P network. Applying network coding over small time-window of...
This paper presents a lightweight but effective mastersender-driven multiple parent approach for online video adaptation and streaming to heterogeneous clients. The proposed design facilitates the cooperation of participating clients for improving the utilization of the spare resources in an overlay. Our design uses standard H.264/AVC video streams. It enables peers to contribute both CPU and bandwidth...
The emerging scalable video coding extension in H.264/AVC standard will enable the deployment of video streaming and distribution applications in heterogeneous environments, with different user bandwidth resources and display capacities. In this paper, we study the problem of how to distribute scalable coded media objects from a media distribution server in peer-to-peer based IPTV applications. All...
Delivering protected seamless content services over heterogeneous networks should be solidly sustained on top of architectures that can offer support for guaranteed quality delivery according to network or consumer requirements. The delivery of personalized, scalable, seamless, and trusted multimedia content delivery, while adequately protecting the content, is a key factor to provide seamless content...
P2P networks have traditionally been used as an enabler for distributed storage and file sharing. With consumer electronics (CE) devices becoming more complex, we can expect a P2P network of CE devices to enable sharing of other resources such as CPU cycles and memory for certain targeted applications. In this paper we present a technique which can enable a P2P network of set top boxes to achieve...
By providing coding ability at intermediate nodes, network coding has been shown to improve throughput in wireless broadcast/multicast networks. Considering a scenario where wireless ad-hoc peers cooperatively relay packets to each other to recover packets lost during MBMS broadcast, we show that by first imposing coding structures globally and then selecting the appropriate types within the structures...
The scalable video coding (SVC) extension of H.264/AVC was designed to support bandwidth efficient and loss resilient video streaming. Its multilayer predictive encoding enables user devices to adapt their video reception by extracting and decoding selected code layers according to device display capability and network throughput. However, this desirable feature is much harder to realize in practice...
