Rate adaptation for adaptive HTTP streaming

Proceedings of the second annual ACM conference on Multimedia systems, 2011
Recently, HTTP has been widely used for the delivery of real-time multimedia content over the Internet, such as in video streaming applications. To combat the varying network resources of the Internet, rate adaptation is used to adapt the transmission rate to the varying network capacity. A key research problem of rate adaptation is to identify network

Combining Stream Switching with Fine-Grained Intra-Stream Adaptation for Adaptive Video Streaming

2005 IEEE 7th Workshop on Multimedia Signal Processing, 2005
Video streaming systems in best effort networks have to somehow cope with dynamically changing bandwidth. Various scalable video codecs allow intra-stream adaptation by use of temporal, spatial, or quality (SNR) scalability; optimizations for finer grained scalability are available as layered coding and FGS techniques.

On adaptive video streaming with predictable streaming performance

2014 IEEE Global Communications Conference, 2014
Adaptive video streaming is an essential tool for improving the performance of video delivery over mobile networks. By dynamically switching between different bit-rate versions of the same video, adaptive video streaming can compensate for and adapt to the ever-changing network conditions inherent in today's 3G/4G networks.

Adaptive P2P Streaming

2012
Widespread adoption of broadband Internet and the introduction of multimedia-capable mobile devices enable the proliferation of many streaming video services. However, best-effort networks are not natively designed to such a purpose. They do not provide any guarantees for delivering the content on time or offer constant service quality.

Adaptive, unsupervised stream mining

The VLDB Journal, 2004
Sensor 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 ...

Green adaptive streaming

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 ...

Adaptive multicast streaming

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.

Watermarking for Adaptive Streaming Protocols

2011
Online 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

Average Performance of Adaptive Streaming

2021 Data Compression Conference (DCC), 2021
This 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.

A watermarking system for adaptive streaming

2014 IEEE International Conference on Consumer Electronics (ICCE), 2014
Content 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
