Recently, there has been much research on video manipulation in the area of video-on-demand and video databases. Most of the recent work has so far focused on video classiication, feature extraction, spatial reasoning and image retrieval (video access); little work has been done on supporting adaptive video editing and production activities, nor has there been much work done on providing facili...

Copyright Protection is one of the many aspects of implementing a commercially successful video streaming solution. Copyright protection should be implemented using both passive schemes – such as watermarking – and active schemes – such as encryption. While some algorithms for encryption of video have been proposed, they are in the main unsuitable for implementation in a streaming video environ...

In this paper, we will address the problem of designing an interactive video server employing multiprocessors. An interactive video server needs to provide quick response to user's requests. When the video stream is a sequence of short video clips and if the order in which these clips are played out is determined by the user, the video clips need to be started up fairly quickly to give an impre...

The cache replacement algorithm plays an important role in the overall performance of Proxy-Server system. In this paper we have proposed VoD cache memory replacement algorithm for a multimedia server system. We propose a Rank based cache replacement policy to manage the cache space in individual proxy server cache. Proposed replacement strategy incorporates in a simple way the most important c...

The Fast Broadcasting scheme is one of the simplest schemes that provide video services. In this scheme, the video is divided into equal-sized segments depending upon the bandwidth allocated by the video server. If the video length is not known, then this scheme cannot be applied as the number of video segments cannot be determined. In a live video wherein the video size is unknown, especially ...

This paper describes the design and implementation of desktop video conference system using client-server and P2P(Peer to Peer). This systems is based on a client-server and P2P architecture, where clientserver is used for the communication with the MCU(Multipoint Control Unit) and P2P is used for the real time video conference. Also, developed system is tested by the desktop video conference s...

This paper explores a data placement method based on rate staggering to store scalable video data in a diskarray-based video server. Scalable video means a video which is coded in such a way that subsets of the full video bit stream can be decoded to create low quality/resolution videos. Supporting layered multiple resolutions from a video server is very desirable in many applications. Note tha...

In a distributed environment, mobile code can be used to dynamically adapt a server in order to take into account the characteristics of the underlying environment. It cal also extend the services offered by the server. In this paper, we present an experiment which consists in adapting a multimedia application using mobile agents programmed in Java. In this distributed application, an agent is ...

Abstract—This paper proposes an interactive map streaming system in mobile environment. The system consists of two parts: a map streaming server and location collecting clients. The map streaming server captures map screen periodically and makes video stream to send it to a client. The client plays the streaming video and detects the location of the user to send to the server. The server side m...

We present a video management system comprising a video server and a mobile camera-phone application called MobiCon, which allows users to capture videos, annotate them with metadata, specify digital rights management (DRM) settings, upload the videos over the cellular network, and share them with others. Once stored in the video server, users can then search their personal video collection via...
