Adaptive, unsupervised stream mining
The VLDB Journal, 2004Sensor devices and embedded processors are becoming widespread, especially in measurement/monitoring applications. Their limited resources (CPU, memory and/or communication bandwidth, and power) pose some interesting challenges. We need concise, expressive models to represent the important features of the data and that lend themselves to efficient ...

Watermarking for Adaptive Streaming Protocols
2011Online multimedia distribution is often done by means of adaptive streaming protocols. To protect this content, its owners apply a unique watermark to each copy. However, sending a unique copy to each client incurs a prohibitive cost, especially in terms of bandwidth and server load, and embedding a watermark on a client device not only compromises the

Proceedings of the 12th ACM International Conference on Computing Frontiers, 2015
In November 2014, MPEG released a new standard, named Green Metadata, that enables energy-efficient media consumption on consumer devices [4]. This standard specifies metadata for reduction of power consumption during encoding, decoding and display. It specifies in particular some metadata for energy-efficient media selection using DASH standard [3 ...

2013 IEEE International Symposium on Broadband Multimedia Systems and Broadcasting (BMSB), 2013
Adaptive streaming has become state of the art for video-on-demand (VoD) and unicast live-streaming. Existing services are based on HTTP, generally offering group-of-picture (GoP)-aligned segments of data in different qualities on an HTTP server for the client to choose from according to available bandwidth.

A watermarking system for adaptive streaming
2014 IEEE International Conference on Consumer Electronics (ICCE), 2014Content providers use forensic watermarking, a technique for tracing individuals who illegally redistribute content, as one of the means to fight Internet content redistribution piracy - the top threat for many content providers around the world. As adaptive streaming becomes one of the main mechanisms for delivering premium multimedia content over the

Average Performance of Adaptive Streaming
2021 Data Compression Conference (DCC), 2021This paper analyzes the average behavior of video streaming systems with adaptation to network bandwidth and player sizes. The main results are formulae for average system performance parameters such as average system bandwidth consumption, average delivered quality, etc.

Adaptive streaming on heterogeneous networks
Proceedings of the 1st ACM workshop on Wireless multimedia networking and performance modeling, 2005Specific network protocols, like MobileIP, offer seamless connectivity to mobile systems. However, the QoS requirements of streaming applications and video conferencing systems require an approach that spans across different layers of the network stack.

Adaptation algorithm for adaptive streaming over HTTP
2012 19th International Packet Video Workshop (PV), 2012Internet video makes up a significant part of the Internet traffic and its fraction is constantly growing. In order to guarantee best user experience throughout different network access technologies with dynamically varying network conditions, it is fundamental to adopt technologies enabling a proper delivery of the media content.

An Adaptive Stream Synchronization Protocol
1995Protocols for synchronizing data streams should be highly adaptive with regard to both changing network conditions as well as to individual user needs. The Adaptive Synchronization Protocol we are going to describe in this paper supports any type of distribution of the stream group to be synchronized.
