Video-on-demand (VOD) is expected to become one of the most important and successful services to be offered on emerging technologies. There is not just an interest in the delivery of digital video for home entertainment purposes, but there are also several educational and commercial benefits from this service. However, for this service to become viable, it is important that the video servers me...

In this paper we present a new visualization framework called openVisaar. Our client-server framework is mainly based on the portable scenegraph system OpenSG. For remote visualization the MP4Live server is used on each client node of the cluster to encode ISO-compliant MPEG-4 video streams in real-time. The encoded video streams are multicast from each cluster client node to the remote applica...

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 ...

In the Internet, video streaming requires greater amount of network bandwidth and other resources as the number of user requests increases. In case of traditional centralized directory server approach all the users requests are directly handled by the centralized server and each user request will send dedicated stream by the server, which requires higher end server, server cost will become more...

Thrifty scheduling is an algorithm that improves the responsiveness of a stripe-scheduled multimedia server. It increases the determinism of the data-distribution service, reduces the likelihood of high startup delays, and enables an increase in the rated load of the system. A stripe-scheduled media server is a distributed video-on-demand system that load-balances by striping video data across ...

This paper presents a system to transmit the information from a static surveillance camera in an adaptive way, from low to higher bit-rate, based on the on-line generation of descriptions. The proposed system is based on a server/client model: the server is placed in the surveillance area and the client is placed in a user side. The server analyzes the video sequence to detect the regions of ac...

Due to the large number of disks involved in a video server, fault-tolerance is an important issue. Trandi-tional parity and duplex based approaches provide the data redundancy but do not guarantee the full availability of the service in the presence of even a single disk failure. If a video server would like to provide non-disruptable service to a large number of viewers, the issue of high ava...

Aiming at the development situation of 3G network, realization scheme is proposed based on 3G network B/S mode of embedded family status remote real-time monitoring system, avoid the shortage of traditional surveillance system which cannot networking,require a lot of storage media and query forensics more difficult. By constructing the embedded server can complete video collection, treatment, s...

We present preliminary results toward developing a video server that integrates security mechanisms and digital monoand stereoscopic video sequences (DSVS) into the DICOM standard. The use of public networks such as the Internet for transmitting patientspecific data must comply with local legislation on data security and integrity. The typical heterogeneous hardware and software infrastructure ...

An interactive video-on-demand (VoD) system allows users to access video services, such as movies, electronic encyclopedia, interactive games, and educational videos from video servers on a broadband network. This paper develops a performance evaluation tool for the system design. In particular, a user activity model is developed to describe the usage of system resources, i.e., network bandwidt...
