Last week our SVCVision workshop was held in Lisbon/Portugal. The workshop got a lot of attention from the conference participants, at one point there were more people attending our workshop than the regular conference technical track. All contributions were presented, including two demos. There were many very interesting contributions and it provided a great networking opportunity, since all participants shared a common interest in H.264/SVC.

One paper from our workshop actually received the best paper award (sponsored by CISCO) of the whole conference.

A big thanks goes to all PC members! Thanks to their hard work we were able to organize a well-received and successful workshop.

The technical program for the Workshop on Impact of Scalable Video Coding on Multimedia Provisioning (SVCVision 2010) is now available from the MobiMedia 2010 conference site. The workshop will take place on the 7th of September, 2010. I’m looking forward to meet you in Lisbon!

Our paper with the title “Scalable Video Coding Impact on Networks” was accepted for publication at the Workshop on Impact of Scalable Video Coding on Multimedia Provisioning (SVCVision 2010). Many thanks to the program committee reviewers (see link below) and external (if any) reviewers, who provided excellent insights on how to improve the paper.

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.

Our paper with the title “Efficient SVC-to-AVC Conversion at a Media Aware Network Element” was accepted for publication at the Workshop on Impact of Scalable Video Coding on Multimedia Provisioning (SVCVision 2010). Many thanks to the program committee reviewers (see link below) and external (if any) reviewers, who provided excellent insights on how to improve the paper.

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.

The technical program for the Workshop on Mobile Multimedia Networking (IWMMN 2010) is now available (see below). I will also join the Mobilware conference. If you are in the area, I’d be happy to meet you.

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.
