Slice-and-Patch - An Algorithm to Support VBR Video Streaming in a Multicast-based Video-on-Demand System
In recent years, a number of sophisticated architectures have been proposed to provide VoD service using multicast transmissions. Compared to their unicast counterparts, these multicast VoD systems are highly scalable and can potentially serve millions of concurrent users. Nevertheless, these systems are designed for streaming constant-bit-rate (CBR) encoded videos and thus cannot benefit from ...
متن کاملA Decentralized Prefetching Protocol for VBR Video on Demand
We present high{performance decentralized prefetching protocols for the delivery of VBR video on demand (VoD) from servers to clients across a packet{switched network. The protocol gives constant perceptual quality for high link utilizations. It also allows for immediate commencement of the video upon user request and near instantaneous response to viewer interactions such as pause, resume and ...
متن کاملVbr Video Streaming over Wireless Networks
Video streaming applications over wireless networks have turned out to be immensely popular recently. In this thesis, we first study the buffering schemes for the VBR video streaming in heterogeneous wireless networks. An analytical framework is presented to derive the expected number of jitters and average buffering delay. Through experimenting with a wide range of buffering schemes, we quanti...
متن کاملCall Admission Control Algorithm for pre-stored VBR video streams
We examine the problem of accepting a new request for a pre-stored VBR video stream that has been smoothed using any of the smoothing algorithms found in the literature. The output of these algorithms is a piecewise constant-rate schedule for a Variable Bit-Rate (VBR) stream. The schedule guarantees that the decoder buffer does not overflow or underflow. The problem addressed in this paper is t...
متن کاملVideo caching network for on-demand video streaming
Recent years have seen a tremendous growth in streaming continuous media such as videos over the Internet, resulting in an enormous increase in the demand on various server and networking resources. To minimize service delays and reduce the loads placed on these resources, we propose a Video Caching Network (VCN) that utilizes an aggregated cache space of distributed systems along the delivery ...
