Meet us at the ACM MMSys 2015 in Portland

We are proud to announce that our Demo paper at the ACM MMSys 2015 in Portland, from 18th to 20th of March, got accepted. The demonstration will show our latest cutting edge research on Inter-Destination Multimedia Synchronization. For a sneak preview of the demonstration check out this video.

bitmovin has launched the official product website for the MPEG-DASH player bitdash. The bitdash players enable MPEG-DASH playback on any web browser using either HTML5 as well as Flash, depending on the browser and version, and even on mobile platforms using HTML5. That happens within our player SDK, so that the people using our players do not have to care about that, it simply works everywhere and can be controlled via an unified API. Another key differentiation factor from other DASH-players is that bitdash pays high attention to stability and performance, meaning that bitdash is the player to be the one with the fastest startup delay, best adaption algorithms and thus quality, and of course stability.

Feel free to download a free version on and give it a try! And stay tuned, we will release more information about bitdash – the HTML5/Flash MPEG-DASH player – in the following days!

Meet us at the ACM Multimedia 2014

We are happy to announce that we are going to attend this year’s ACM Multimedia (ACM MM), Orlando, Florida, (Nov. 3-7, 2014.).

Full Paper
Title: Self-Organized Inter-Destination Multimedia Synchronization for Adaptive Media Streaming
Authors: B. Rainer, and C. Timmerer
As social networks have become more pervasive, they have changed how we interact socially. The traditional TV experience has drifted from an event at a fixed location with family or friends to a location-independent and distributed social experience. In addition, more and more Video On-Demand services have adopted pull-based streaming. In order to provide a synchronized and immersive distributed TV experience we introduce self-organized Inter-Destination Multimedia Synchronization (IDMS) for adaptive media streaming. In particular, we adapt the principles of IDMS to MPEG-DASH to synchronize multimedia playback among geographically distributed peers. We introduce session management to MPEG-DASH and propose a Distributed Control Scheme (DCS) to negotiate a reference playback timestamp among the peers participating in an IDMS session. We evaluate our DCS with respect to scalability and the time required to negotiate the reference playback timestamp. Furthermore, we investigate how to compensate for asynchronism using Adaptive Media Playout (AMP) and define a temporal distortion metric for audio and video which allows the impact of playback rate variations to be modeled with respect to QoE. This metric is evaluated based on a subjective quality assessment using crowdsourcing.

HTTP/2.0 and DASH: Planning Tomorrow’s Improved Video Delivery

HTTP traffic has grown extensively driven by the immense growth of multimedia traffic. Nowadays it could be seen as “the” protocol to deploy new services and applications and it is also heavily used by the industry, due to the fact that it provides advanced features for modern Internet architectures:

1. it is a content centric protocol that decouples names from addresses through DNS
2. it provides caching elements and middle boxes as reverse and forward proxies
3. it enables scalable and flexible content deployment with content distribution, already leveraged by Content Distribution Networks (CDN)

However, there is still room for improvements as many services are still using HTTP/1.0 which has been specified in May 1996 or are not utilizing all features of HTTP/1.1 such as persistent connections or pipelining. For example …

PostDoc position (3 years) at Alpen-Adria Universität Klagenfurt, Austria

Institute of Information Technology, Multimedia Communication (MMC) Group (Prof. Hermann Hellwagner)

The MMC group at Klagenfurt University, Austria, is offering a full, three-year PostDoc position (available now) in a basic research project called CONCERT ( Important facts about the project are given in the following. We seek candidates with strong expertise in one or several of the following areas: Multimedia Communication, Machine Learning, Multi-Agent Systems, Uncertainty in Artificial Intelligence (Probabilistic Models, Bayesian Networks, Game Theory). Applications should be sent to Prof. Hermann Hellwagner <>.

Title: A Context-Adaptive Content Ecosystem Under Uncertainty (CONCERT)
Duration: 3 years


  • University College London (UK): Prof. George Pavlou, Dr. Wei Chai (Coordinator)
  • University of Surrey (UK): Dr. Ning Wang
  • Ecole Polytechnique Fédérale de Lausanne (CH): Prof. Pascal Frossard
  • Alpen-Adria-Universität (AAU) Klagenfurt (AT): Prof. Hermann Hellwagner

Project character and funding

CONCERT is an international basic research project accepted as a CHIST-ERA project under the Call for Proposals “Context- and Content-Adaptive Communication Networks”. CHIST-ERA is an ERANET consortium, part of the EC FP7 Programme “Future and Emerging Technologies (FET)” ( Funding is provided by the national basic research funding agencies, in Austria the FWF (Austrian Science Fund).


The objective of CONCERT is to develop a content ecosystem encompassing all rele- vant players which will be able to perform intelligent content and network adaptation in highly dynamic conditions under uncertainty. This ecosystem will have as basis emerging information-/content-centric networking technologies which support in- trinsic in-network content manipulation. The project will consider uncertainty aspects in the following two application domains: (1) social media networks based on user generated content and (2) CDN-like professional content distribution (Content Distri- bution Networks). Three dimensions of uncertainties will be addressed: (1) heteroge- neous and changing service requirements by end users, (2) threats that may have adverse impacts on the content ecosystem, as well as (3) opportunities that can be exploited by specific players in order to have their costs reduced … [read more]
