Michael Ransburg, Eduardo Martínez Graciá, Tiia Sutinen, Jordi Ortiz, Michael Sablatschan, Hermann Hellwagner, Scalable Video Coding Impact on Networks, accepted for publication at Workshop on Impact of Scalable Video Coding on Multimedia Provisioning (SVCVision 2010), Lisbon, Portugal, September 2010.
Abstract:
This paper describes the CELTIC project on “Scalable Video Coding Impact on Networks” with the focus of designing a streaming system based on the Scalable Video Coding extension of the AVC standard. The system is designed to cope with streaming scenarios that can be classified in four use cases: session handover, network congestion, receiver heterogeneity and user driven adaptation. A complete overview of the architecture of the system is given. Two demonstration scenarios are described in detail, which point out the advantages of scalable video coding compared to single layer approaches in multimedia transmission and adaptation scenarios. A concluding section summarizes the work and provides an outlook to future work items.

Michael Sablatschan, Jordi Ortiz, Michael Ransburg, Hermann Hellwagner, Efficient SVC-to-AVC Conversion at a Media Aware Network Element, accepted for publication at Workshop on Impact of Scalable Video Coding on Multimedia Provisioning (SVCVision 2010), Lisbon, Portugal, September 2010.
Abstract:
H.264/SVC, the Scalable Video Coding extension of the H.264/AVC video coding standard, features spatial, quality and temporal scalability. Backwards compatibility with legacy decoding devices is maintained through an H.264/AVC compliant base layer, which represents the lowest quality of an H.264/SVC bit-stream. However, it is often desirable to also provide the higher quality layers to legacy H.264/AVC devices. This is achieved by a process commonly known as “bit-stream rewriting”, which allows for an efficient H.264/SVC to H.264/AVC conversion by exploiting the similarities of the two codecs. This paper describes a demonstrator showing the advantages of including an improved version of the bit-stream rewriting tool from the existing JSVM H.264/SVC reference software in an H.264/SVC-based multimedia delivery system, by integrating it into a Media Aware Network Element.

Today we sent out the acceptance notifications for our workshop on “Impact of Scalable Video Coding on Multimedia Provisioning” (SVCVision). We received a pleasing number of 16 submissions, which allowed us to only select the highest quality papers for the workshop. Out of these 16 submissions we accepted 6 papers as full papers and 5 papers as position or demo papers. This results in an overall acceptance rate of 68.75% for the workshop.
A big thanks goes to all program committee members (see SVCVision). Thanks to your hard work we were able to provide at least 3 (sometimes 4) reviews for every submission.
Thanks as well to all authors who submitted their H.264/SVC papers to the workshop!
As a next step we will work on the technical program. We are excited to meet you all in September in Lisbon.

H.264/SVC is starting to become increasingly popular. This is an overview of companies which offer (or plan to offer) products based on H.264/SVC.
Hardware-accelerated encoders are being worked on by SeaWell Networks with their recently announced Lumen 1000 and Stretch with their VRC6004HD 4 Channel High Definition PCIe DVR Add-in Card. Mainconcept as well as eInfoChips are working on optimized H.264/SVC software CODECs (Mainconcept, eInfochips). Vidyo, Radvision and Global IP Solutions (who got bought by Google recently) are using H.264/SVC in their video conferencing solutions (Vidyo, Radvision, Global IP Solutions). Finally, Aventura are using H.264/SVC in their CCTV products.
Do you know of more companies offering H.264/SVC products? Please let me know and I’ll add them to the list.

Michael Ransburg, Mario Jonke, and Hermann Hellwagner, An Evaluation of Mobile End Devices in Multimedia Streaming Scenarios, accepted for publication at First International Workshop on Mobile Multimedia Networking (IWMMN 2010), Chicago, USA, June 30, 2010.
Abstract:
This paper compares handhelds based on the iPhone and Android operating systems in multimedia streaming scenarios. We simulate typical Internet network impairments, i.e. packet delay and packet loss, and evaluate their effects on the end devices. Additional evaluations include bandwidth overhead inflicted by the different streaming approaches and traffic shape and fairness when both handhelds consume media simultaneously. Based on the quantitative evaluation, both approaches show weaknesses and strengths. A final qualitative discussion points out additional advantages for the streaming approach implemented in the iPhone operating system.

I usually do not blog about my photography, but everyone who knows me or follows me on Twitter knows that I’ve quite a passion for it. This time I make an exception, since it’s not every day that one of my photos gets published in National Geographic.
The photo below showing the “Lindwurm” (a monument in my home city Klagenfurt) was published in the April 2010 issue of National Geographic Russia. The photo is also available on my Flickr account, where the photo editor of National Geographic Russia originally found it.
Their photo editor contacted me some time ago. They were going to write a story on the Lindwurm in their April 2010 issue on “Fossil Countrymen”. The story is about how the Lindwurm came to be as a monument modeled after an animal skull of a woolly rhinoceros, an extinct mammal originally at home (not only) in Russia. At least, this is what I could translate from the original National Geographic article, which can be seen below.
I’m very happy that my photo was selected for this. Additionally, now I know how my name is written in Russian: МИХАЭЛЬ РАНСБУРГ 
If you want to take a look at my other photos, please visit my Flickr page!

++ OVERVIEW ++
In an effort to address and overcome some of these open issues that hinder effective access and interaction of multimedia content, this workshop will bring together individuals from a number of research communities, including but not limited to Multimedia Distribution and Access, Social Network Analysis, Multimedia Content Analysis, and User Modelling Adaptation and Personalization. It is our belief that a synergetic approach involving these areas of work can exceed their individual potentials, leading to improved access, understanding, and retrieval of multimedia content. The main objective of this workshop is to provide a forum to disseminate work that explicitly exploit the synergy between multimedia content analysis, personalisation, and next generation networking and community aspects of social networks. We believe that this integration could result on robust, personalized multimedia services, providing users with an improved multimedia experience.
In particular, user modelling and adaptation techniques can help alleviate the above problems by taking the user into consideration when accessing multimedia content. Information related to the user such as interests, current context or past interaction behaviour can provide additional valuable information that allows multimedia systems to better present, adapt, retrieve, or understand multimedia content. In addition, this workshop will also focus on the analysis of user networked communities, which can potentially provide richer and more structured information related to users and multimedia content. Hence, this workshop is distinct from and complementary to previous initiatives in that it involves the integration
multimedia content analysis techniques with information derived from users, networked communities, and context awareness.
