Efficient Bandwidth Estimation for HTTP adaptive streaming

The International Conference on Information Networking 2014 (ICOIN2014), 2014
As the multimedia devices are becoming more diverse and the HTTP adaptive streaming techniques grow in popularity, the transmission of adequate video quality becomes increasingly important. HTTP adaptive streaming requires accurate information about available bandwidth of client for quality adaptation.

Dynamic adaptive HTTP streaming of live content

2011 IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks, 2011
MPEG has recently released a first public draft of the new Dynamic Adaptive Streaming over HTTP (DASH) specification. The new streaming technique is based on the 3GPP and partly also on the Open IPTV Forum (OIPF) specifications. In this paper, we give an overview about the new DASH specification with a special focus on Live streaming services. In order

Dependency-aware caching for HTTP Adaptive Streaming

2016 Digital Media Industry & Academic Forum (DMIAF), 2016
There has been significant interest in the use of HTTP adaptive streaming for live or on-demand video over the Internet in recent years. To mitigate the streaming transmission delay and reduce the networking overhead, an effective and critical approach is to utilize cache servers between the origin servers and the heterogeneous clients.

Modeling live adaptive streaming over HTTP

Computer Communications, 2016
Video streaming methods have evolved greatly over the years. Today, the most prevalent technique to stream live and video on-demand is the adaptive HTTP streaming and is used by several commercial vendors. In this paper, we present an approximate analytic model for live adaptive streaming over HTTP.

Interactions between HTTP adaptive streaming and TCP

Proceedings of the 22nd international workshop on Network and Operating System Support for Digital Audio and Video, 2012
HTTP adaptive streaming (HAS) is quickly becoming a popular mechanism for delivering on-demand video content over the Internet. The chunked transmission and application-layer adaptation create a very different traffic pattern than traditional progressive video downloads where the entire video is downloaded with a single request.In this paper, we ...

QoE Assessment of HTTP Adaptive Video Streaming

2015
Quality of Experience (QoE) is a crucial characteristic of any multimedia service and must be accounted for during the service development and planning stages. Nonetheless, given its subjective nature, it is extremely difficult to use analytical methods to estimate the average Mean Opinion Score (MOS).

DRM protected dynamic adaptive HTTP streaming

Proceedings of the second annual ACM conference on Multimedia systems, 2011
Dynamic adaptive HTTP streaming (DASH) is a new concept for video streaming using consecutive downloads of short video segments. 3GPP has developed the basic DASH standard which is further extended by the Open IPTV Forum (OIPF) and MPEG. In all versions available to date, only very simple content protection use cases are enabled.

Quality of experience for HTTP adaptive streaming services

IEEE Communications Magazine, 2012
The growing consumer demand for mobile video services is one of the key drivers of the evolution of new wireless multimedia solutions requiring exploration of new ways to optimize future wireless networks for video services towards delivering enhanced quality of experience (QoE).

Dynamic adaptive streaming over HTTP dataset

Proceedings of the 3rd Multimedia Systems Conference, 2012
The delivery of audio-visual content over the Hypertext Transfer Protocol (HTTP) got lot of attention in recent years and with dynamic adaptive streaming over HTTP (DASH) a standard is now available. Many papers cover this topic and present their research results, but unfortunately all of them use their own private dataset which -- in most cases -- is ...

Evaluation of adaptive streaming algorithms over HTTP

2013 IEEE Third International Conference on Consumer Electronics ¿ Berlin (ICCE-Berlin), 2013
In order to guarantee the best user experience throughout different network access technologies with dynamically varying network conditions, it is fundamental to adopt new technologies enabling a proper reception of the multimedia content. In this paper we implemented a prototype of streaming client, based on the MPEG DASH standard.
