The performance of a Video-on-Demand (VOD) system is significantly impacted by the throughput of its storage subsystem. Current VOD storage subsystem normally consists of an array of hard disks organized in some RAID organizations. Although it can achieve a large storage capacity, its actual throughput could be lower than its ideal bandwidth. This is mainly because some popular videos receive m...

Using proxy cache is a key technique that may help to reduce the loads of the server, network bandwidth and startup delays. Basing on the popularity of clients’ request to segment video,we extend the length for batch and patch by using dynamic cache of proxy cache for streaming media. Present transmission schemes using dynamic cache such that unicast suffix batch, unicast patch, multicast patch...

Omnidirectional image and video, also known as 360 image and 360 video, are gaining in popularity with the recent growth in availability of cameras and displays that can cope with such type of content. As omnidirectional visual content represents a larger set of information about the scene, it typically requires a much larger volume of information. Efficient compression of such content is there...

The online video service need the support of CDN(Content Delivery Networks). Compared with traditional CDNs, it can save a lot of cost by using cloud-based storage nodes to deliver the video content. To guarantee end users’ QoS, CDN should pre-deploy the content files of online video service to the edge nodes which are close to the users. Existed researches have shown that the cost of building ...

WITH THE ADVENT of targeted advertising and the popularity of data mining, users find their privacy threatened. To address this rising concern, researchers have proposed many privacypreserving mechanisms.1 Most of these mechanisms have strong theoretical guarantees but often lack practicality. For instance, reaching a sufficient level of privacy often requires sanitizing (distorting) user data ...

A concise paper for an invited presentation for the IEE colloquim on “Distributed systems support for digital audio and video”. Object distribution has been regarded as one of the most important paradigms for distributed processing since the early eighties. The increasing popularity of digital audio and video applications presents new challenges to the traditional object distribution models. Th...

In the United States, video game playing is an immensely popular form of entertainment; the majority of adults will have had some experience with video games during their lives (Rideout et al., 2010). As the popularity of video games in entertainment has increased, so has interest in exploring the potential effects that video games may have on learning and generalizable cognitive ability. Educa...

Video streaming over wireless (networks) has gained popularity in recent times with the development of heterogeneity networks. The demand and market for video based services is expected to grow substantially in the future. In that network is used for video streaming, the inherent unreliability of frequently results in corrupted video packets and jitter during video playback. Such an aberration ...
