With the development of innovative network infrastructure and increasing bandwidth availability, live video streaming is emerging as an attractive application for end users and the industry. Due to the heterogeneity in user resources as well as bandwidth fluctuations, we argue that, to provide high quality-of-service, it is desirable to tailor (on-the-fly) the bit rate of video streams, according...
In this paper, we present a dynamic caching and replacing mechanism for the multiple videos over quality of service networks. The metafile containing the metadata about the video is maintained for caching and replacing mechanism. The caching algorithm employs the sliding window method to select the frame that has to be cached. The sliding window mechanism uses the beneficial value which is calculated...
With the advances in the Internet and mobile networks, consumers now wish to enjoy their live and on-demand multimedia contents anytime, anywhere and across any device. Scalable Video Coding (SVC) provides a very attractive solution to achieve this goal. However, SVC streams themselves are not stream-able by a streaming server. The SVC streams must be stored in a proper file format to facilitate packet-based...
This paper proposed an adaptive video transmission control scheme in wireless networks. The first job is how to reduce the amount of the image data that must be transmitted on the wireless channel. We compare the deviation of two consecutive frames in the video stream and decide whether or not the follow-up frame should be transmitted. If the deviation of two consecutive frames not reach the threshold,...
In recent years, the video streaming service has become one of the most important applications. The rapid growth of users raises a big challenge to the traditional client-server VoD service. In order to provide large scale VoD service with lower server bandwidth cost, P2P technology has been introduced to VoD service. P2P based VoD service provides the same user experience as the client-server mode...
This paper builds on an interactive streaming architecture that supports both user feedback interpretation, and temporal juxtaposition of multiple video bitstreams in a single streaming session. As an original contribution, we explain how these functionalities can be exploited to offer improved viewing experience, when accessing high-resolution or multi-views video content through individual and potentially...
This paper proposes a remote thin client system for real time multimedia streaming over VNC. A remote frame can be split as two parts, i.e. high motion part and low motion part, and transmitted through the Internet from servers to clients according to the proposed hybrid RTP protocol. A Dynamic Image Detection Scheme (DIDS) is proposed to automatically detecting the high motion part of a frame with...
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...
The main idea of this paper is using a manager server on the top of the tree-based P2P network construction for smartly providing alternative parent peers to reconnect in a case, when the downloading parent is down or crashes. The solution for these issues is considered to use minimum reconnection time for the parent change and solving the problem as lack in alternative peers. This is one of the main...
The paper proposes a peer-to-peer solution for video surveillance system which decreases the transmission pressure of server significantly through one client receives video stream and then forwards them to other clients at the same time. The system model and the establishing algorithm of forwarding tree are described and the analysis of how to improve the performance of the system is also discussed.
Development of network monitoring tools for realtime rich-media (RTRM) applications remains a challenge for both academic and industrial researchers as the complexity of the computational processing varies dynamically. We propose a novel, flexible and cost effective technique which can be implemented in ordinary network environment to monitor QoS parameters such as packet-delay, packet-loss, packet...
This paper presents the methodologies taken to integrate open-source LIVE555 based data streamer with a baseline H.264 encoder running on the Texas Instruments's DaVinci based embedded platform. The system implemented is able to stream live H.264 encoded video over the network, and be displayed on remote stations using the VLC media player. The system developed provides an embedded platform to implement...
We take an analytical approach to study Quality of user Experience (QoE) for media streaming applications. We use the fact that random linear network coding applied to blocks of video frames can significantly simplify the packet requests at the network layer and avoid duplicate packet reception. We model the receiver's buffer as a queue with Poisson arrivals and deterministic departures. We consider...
Multi-view video streaming over P2P network has emerged as a scalable solution for providing multi-view video service on Internet, as it utilizes users' bandwidth resource to reduce streaming server's bandwidth cost when delivering the dataintensive multi-view video. However, the view switching behavior in multi-view video introduces excessive dynamic to the system, which brings two performance issues...
Computer game processing requirements for the CPU and graphics performance are growing all the time higher. At the same time many low cost and modest performance CE devices are gaining popularity. People are already used to mobile life style inside home and on the go and they want to enjoy entertainment everywhere. This paper describes an accelerated video streaming method used in a gaming system,...
This paper builds on an interactive streaming architecture that supports both user feedback interpretation, and temporal juxtaposition of multiple video bitstreams in a single streaming session. As an original contribution, these functionalities can be exploited to offer improved viewing experience, when accessing football content through individual and potentially bandwidth constrained connections...
We present network flow buffering, which is the use of a remote flow-regulating buffer that is deployed between a Web client and server to improve performance of HTTP-based playback of video. We show that HTTP enhanced with network flow buffering significantly improves performance, especially under high packet loss and highly variable bandwidth conditions, when compared with using either straight...
Modern distance education requires the high-capacity, large throughput of video network. A good video education platform is the foundation of the remote network on-demand and live teaching. However, there is the large gap between the reality of network environment and the real-time interactive requirements of modern network teaching mode, which desires real-time and continuous transmission of a large...
This paper explores the effect of varying peers' local cache sizes on user perceived video quality in Video-on-Demand p2p streaming. First, we ascertain the relationship between the average video distortion on peers and peer cache size. Second, we analyze the aggregate access network usage of uplink bandwidth for different peer cache sizes. Finally, we measure the p2p server bandwidth usage as the...
File sharing applications using Peer-to-Peer (P2P) networks such as Bittorrent or eDonkey rapidly attracted a lot of people and proved the efficiency and interest of this P2P technology. Distribution of video and of live contents also experienced the P2P mechanisms with success. PPLive, UUSee and others have many of customers, hundreds of channels and thousands of concurrent users. However, major...
