In this paper, we present the Global Video Environment (GloVE), which is a novel scalable VoD system based on the stream reusage technique called Cooperative Video Cache (CVC), where the clients cooperate to create a distributed video repository used as the prior source of content. In GloVE, differently from conventional systems, the server’s bandwidth does not limit the number of simultaneous ...

Monitoring facilities will be necessary and useful for our daily life, because it is very important for us to think about our security. This work developed an remote video surveillance system, which is organized with an integrated web server, network cameras, remote control devices and clients which connected to internet. Some kinds of devices can be used as our clients , for example, high-perf...

We propose a systems approach to providing video service that integrates the multi-resolution data generated by scalable compression algorithms with the high-bandwidth, high-capacity storage provided by disk arrays. We introduce two layout strategies for storing multi-resolution video data on magnetic disk arrays, which vary in the degrees of parallelism and concurrency they use to satisfy requ...

Multiparty conferencing is an important telephony service, provided in the PSTN by conference bridges. Internet telephony can enhance this basic service by video conferencing and collaborative work. The Session Initiation Protocol (SIP) can support many different conferencing architectures, including the centralized conferencing server model. We describe design issues and challenges in implemen...

This paper addresses the design problems concerning a large scale parallel video on demand server that consists of multiple clusters of nodes connected by a high performance interconnection network In order to e ciently control the ow of video streams we propose two scheduling algorithms for data retrieval and communica tion First we present a disk scheduling algorithm called round scheduling w...

Server bandwidth has been identified as a major bottleneck in large Video-on-Demand (VoD) systems. Using multicast delivery to serve popular content helps increase scalability by making efficient use of server bandwidth. In addition, recent research has focused on proactive schemes in which the server periodically multicasts popular content without explicit requests from clients. Proactive sche...

For the actual Video-On-Demand (VOD) service environment, we implement a cluster-based VOD server composed of general PCs and adopt the parallel processing for MPEG movies. For the implemented VOD server, a video block recovery mechanism is designed on the RAID-3 and the RAID-4 algorithms. However, without considering the architecture of cluster-based VOD server, the application of these basic ...

Many studies and research are continuously being developed to improve the quality capability of video compression. Compression is done with help a codec, in there several types codecs including VP8 H.265. These two codec models have very high resolutions for video. In implementing calls, determination has not been able prove results quality. To be know resulting video, testing can through pixel...

We present a video analysis and indexing engine, that can perform fully automatic scene segmentation and feature extraction, in the context of a television archive. A template-based indexing engine is proposed, which interacts with a general-purpose video analysis server (providing spatio-temporal segmentation, feature extraction, feature clustering and feature matching services) and a template...

CDN (Content Delivery Networks) improves end-user performance by replicating web contents on a group of geographically distributed servers. However, repeatedly keeping the entire replica of the original objects into many content servers consumes too much server resource. This problem becomes more serious for the large-sized objects such as streaming media, e.g. high quality video. In this paper...
