This paper describes the experience with Real-Time Mach for writing a network server and a storage server which are suitable for handling audio and video, and a video-on-demand system on these servers. Audio and video are commonly referred to as timing-dependent continuous media. Programming interfaces and resource management policies of current operating systems should be changed for handling ...

The bandwidth-intensive and long-lived nature of high quality digital video make it a challenging problem to transmit such video over the Internet. In this paper, we consider the problem of streaming a set of popular videos from a remote server to a large number of asynchronous clients, while making efficient use of network bandwidth, and still allowing clients to start instantaneous playback. ...

This paper presents a dynamic energy management policy for a wireless video streaming system, consisting of battery-powered client and server. The paper starts from the observation that the video quality in wireless streaming is a function of three factors: encoding aptitude of the server, decoding aptitude of the client, and the wireless channel. Based on this observation, the energy consumpti...

Video eeects play an important role in adding production value to video programs. The use of video eeects with Internet Video sources, however, is still uncommon because traditional hardware-based solutions are poorly suited to the Internet environment. In previous work, we described a parallel, software-only video eeects system designed for Internet Video and explored the use of temporal paral...

A Video-on-Demand system (VoD) [1] integrates the entertainment, telecommunication, and computer industries and provides electronic video rental services to geographically dispersed users from remote video servers on a broadband network. Several techniques have been proposed to increase the number of concurrent viewers of popular movies through better usage of resources. One technique uses the ...

In this paper, a novel real-time video and data capture of vehicle accident is proposed in Intelligent Transportation System (ITS). The proposed scheme solves the problem of huge storage needed for recording vehicle accident in the smart vehicle and in the remote ITS server. It works efficiently with small amount of storage size and guarantee saving accident video in secondary storage. It enabl...

In this paper, we propose, design, implement, and evaluate a proxy caching system for MPEG4 video streaming services for heterogeneous users. In our system, a video stream is divided into blocks for efficient use of the cache buffer and the bandwidth. A proxy retrieves a block from a server, deposits it in its local cache buffer, and provides a requesting client with the block in time. It maint...

In this paper, we study in hybrid peer-to-peer (P2P) streaming system, which includes fixed peers and mobile peers in the same network, and propose a flow rate allocation algorithm to optimize the streaming system. In the proposed algorithm, based on transcoding technique, we describe how to exchange original and transcoded data among video source server, fixed and mobile peers. The purpose of ...

Video streaming applications have newly attracted a large number of participants in a distribution network. Traditional client-server based video streaming solutions sustain precious bandwidth provision rate on the server. Recently, several P2P streaming systems have been organized to provide on-demand and live video streaming services on the wireless network at reduced server cost. Peer-to-Pee...
