As compared to live peer-to-peer (P2P) streaming, modern P2P video-on-demand (VoD) systems have brought much larger volumes of videos and more interactive controls to the Internet users. As the increase of bitrate of the videos and the full VCR controls of P2P VoD, the behavior “buffering” motivates us to design different schedule and service strategies for peers, to improve the playback performance,...
Network coding is known to provide increased throughput and reduced delay for communications over networks. In this paper we propose a peer-to-peer video streaming system that exploits network coding in order to achieve low start-up delay, high streaming rate, and high resiliency to peers' dynamics. In particular, we introduce the concept of random multicast trees as overlay topology. This topology...
Using streaming media technology can effectively break the bandwidth bottleneck and make video/audio streaming over Internet smoothly. Based on the campus network facility and multimedia network classroom, this article use streaming media technology to form a network of teaching, analysis of the streaming media architecture, give a description of the system to connected and technical points, and make...
With the rapid development of video streaming era, multipath video streaming comes as a promising solution. However, dividing the video into different sub-streams is still considered as an important challenge for researchers. In this paper, we propose an approach for generating multiple complementary descriptions of the video flow, then to couple these descriptions with the path diversity provided...
A new genre of P2P systems, P2P Video-on-Demand (P2P-VoD), has not only received substantial recent research attention, but also been implemented and deployed with success in large-scale real-world streaming systems, such as PPLive. The essential characterization of P2P-VoD systems is to take full advantage of peer upload bandwidth contribution with a cache on each peer. Meanwhile, the asynchronous...
This paper discusses the proposed system that analyses the performance of the prototypes of threaded HTTP servers on Hyper-Threading as well as non-Hyper-Threading platforms. Once the performance benefits for the prototype HTTP servers are recorded, these would be helpful in building various client-server interfaces over the network. This paper aims at writing HTTP Web-Servers for the 4 basic Threading...
Live multimedia streaming applications operate more efficiently when organized in a peer to peer (P2P) topology. The upload capacity of the peers is utilized to support other peers thereby alleviating the load from the streaming server. Many peer to peer models have been proposed for live multimedia streaming but they have drawbacks including low resource utilization and high startup and source to...
In wireless networks, bandwidth is extremely scarce, especially for supporting on-demand media streaming. This study uses simulation to examine a caching hierarchy for wireless streaming video distribution, in combination with multicast stream merging. The main purpose is to gain insight into the filtering effects caused by caching and merging. Three metrics, namely entropy, request frequency vector,...
