Dynamic video playout smoothing method for multimedia applications

User Control and Dynamic Reorganization of Multimedia Presentations During Playout

We introduce a methodology to dynamically adjust the multimedia presentations as a result of user interactions during the playout. A constraint-driven approach is described for the automated assembly, organization and playout of presentations from multimedia databases. To allow interactive user control over the playout of an automatically generated presentation, an arbitrary number of control b...

Multimedia Proxy Caching for Video Streaming Applications

This paper deals with the use of proxy servers to cache streaming video objects. In this paper, we describe a streaming architecture for layered video objects that uses the concept of layered caching. A new replacement policy is proposed, which is based on the playout time of a video object at the client. We define a new quality metric that takes the number of layers as well as the importance o...

Adaptive playout for low latency video streaming

Network variations in video streaming require to prebuffer sufficient data at the client prior to playout. This receiver buffer prevents the display process from starvation in case of network congestion. Prebuffering, however, is also responsible for the major part of the delay between requesting a media stream and playing it at the receiver. In this paper we show how adaptive media playout can...

Dynamic Reconfiguration for Complex Multimedia Applications

Current state-of-the-art distributed multimedia applications require an environment that provides stable Quality of Service (QoS). However, these applications typically run on best-effort heterogeneous platforms, and compete with other applications or connections for end system and network resources, hence suffer from instability and dynamic variations with regards to QoS. In this paper, we pre...
