MMSys 2017 - Welcome Reception & Banquet

Thank you everyone for making the Conference a huge success!

The 8th ACM International Conference on Multimedia System (MMSys 2017) was successfully held in Taipei, Taiwan from June 20 - 23, 2017 with co-located workshops NOSSDAV, MMVE, and NetGames. Thanks to all who came to the Conference from all over the world and made it a huge success. We would like to also thank all the distinguished speakers for their wonderful and fruitful speech. MMSys 2017 came to a successful end.


The ACM Multimedia Systems Conference (MMSys) provides a forum for researchers to present and share their latest research findings in multimedia systems. While research about specific aspects of multimedia systems are regularly published in the various proceedings and transactions of the networking, operating system, real-time system, and database communities, MMSys aims to cut across these domains in the context of multimedia data types. This provides a unique opportunity to view the intersections and the inter-play of the various approaches and solutions developed across these domains to deal with multimedia data types.


In the morning of June 20, the conference officially started with five Overview Talks. The following overview talks have been given at MMSys: "Geometric representations of 3D scenes" by Géraldine Morin, University of Toulouse in France, "Humans, computers, delays and the joys of interaction" by Ragnhild Eg, Westerdals Oslo School of Arts in Norway, "Context-aware, perception-guided workload characterization and resource scheduling on mobile phones for interactive applications" by Chung-Ta King, National Tsing Hua University & Chun-Han Lin, National Taiwan Normal University, "Towards Understanding Truly Immersive Multimedia Experiences" Niall Murray, Athlone Institute of Technology in Ireland, "Rate Control In The Age Of Vision" by Ketan Mayer-Patel, University of North Carolina at Chapel Hill.


Following these five inspirational overview talks, the official opening remarks started in the afternoon by Kuan-Ta Chen, General Chair of ACM Multimedia Systems Conference 2017, and continue with the first keynote "The AR/VR Renaissance: opportunities, pitfalls, and remaining problems" delivered by Prof. Henry Fuchs, Federico Gil Professor, University of North Carolina at Chapel Hill. The first day of the conference ended with a welcome reception at LE BLE D'OR (Miramar)


The second keynote speech "Towards Large-scale Deployment of Intelligent Video Analytics Systems" was delivered by Dr. Julien Lai, Director of the Applied DL team of NVIDIA APAC Region , on June 22 Thursday (Main Conference - Day 3).

During Main Conference Day 2 & 3, we have total 6 Industrial talks. These informative industrial talks included: "Semantic Awareness in 360 Streaming" by Dr. Shannon Chen, Research Scientist of Facebook 360 Media Team, "On the frontiers of Video SaaS" by Dr. Sega Cheng, Co-founder & CEO of, "What challenges are we facing after Netflix revolutionized TV watching?" by Dr. Shuen-Huei Guan, Technical Director of KKStream Limited, "The innovation and challenge of Interactive streaming technology" by Mr. Wesley Kuo, Founder of i@solution & Ubitus, "The overview of app streaming technology" by Dr. Sam Ding, CEO of VMFive, "Virtual Reality – The New Era of Future World" by Mr. WeiGing Ngang, Relationship Manager, HTC VIVE.


This year, ACM MMSys 2017 research track attracted 47 full paper submissions with 13 got finally accepted. It was carefully assigned to reviewers in the same field and each PC was assigned up to 4 papers (only 3 of them got 4). Each paper gets at least 3 reviews (majority of them get 4) and extra reviews are requested for papers with conflicting reviews. In addition to the full paper submissions, MMSys 2017 hosted 4 special sessions: Cloud-based multimediaMulti-sensory experiencesImmersive Experiences in AR and VRIoT connectivity and infrastructure. The demo sessions promote applied research, application prototypes and systems along with the scientific program. The sessions not only showcase the applicability of recent results to real-world problems but also trigger ideas exchanges between theory and practice and collaborations between MMSys attendees. In addition, The Open Dataset and Software Track was held at the 2nd Conference Room, software has been added to the (tranditional) Open Dataset Track this year.


ACM MMSys 2017 hosts three workshops during the last day of the conference: The 27th ACM SIGMM Workshop on Network and Operating Systems Support for Digital Audio and Video (NOSSDAV), The 9th International Workshop on Massively Multiuser Virtual Environments (MMVE), and the The 15th Annual Workshop on Network and Systems Support for Games (NetGames).

Prof. Bo Li | Professor in the Department of Computer Science and Engineering, HKUST

Abstract: Cloud computing has taken the industry by a storm in the past decade, which, as the backend engine, has been affecting and improving our daily lives. One interesting aspect in this new computing paradigm is that communication take place not just at the edge of the system that interface with users, but plays a key role at the heart of datacenters, where large volumes of intermediate results have to be delivered to the next stage of data analytic jobs as quickly as possible, and video analytics is one of such examples with very high resource demands. In this talk, we will discuss the resource allocation for cloud computing in general, and present the case for scheduling multiple types of resources in the cloud, with the hope of supporting multiple co-existing jobs in a fair and efficient manner. With the recently introduced notion of coflow, a correlated group of flows, whose completion time is determined by the flow finishing last. We show the optimal solution relies on resolving a set of conflicting criteria, and we will illustrate some existing approaches and our endeavours along this direction.

Dr. Shun-Yun Hu | Co-Founder of Imonology Inc., Taiwan

Abstract: As we start to experience exponential growth in tech and productivity in certain areas, some pioneers are foreseeing a future where most society members do not need to work (in the traditional sense) for the society to support itself in most basic needs. Universal Basic Income (UBI) therefore has been proposed as a remedy to protect against the loss of job security, in a future where productivity of physical goods might far exceed demands.

Developments in Virtual Reality (VR) and Virtual Environments (VE) on the other hand, might just fill in the gap for people to find something to do and to work on, in a space that is literally limited only by humanity's imagination.

In this talk I will present both a "Good" and a "Bad" scenario of how this future might go, so that as researchers and technologists, we might start to reflect and think about how our works might impact society, knowingly or unknowingly, into humanity's bright (or dim) future. In hope that we will collectively secure ourselves a future that we all want to live in.

syhu Shun-Yun has been doing research in scalable virtual environments using peer-to-peer (P2P) techniques since 2003, and has published his works as both research papers and free software projects (VAST and Scalra). After adventuring in Sierra games at 7 and Ultima VII later, Shun-Yun has since been fascinated by the possibilities of games and virtual worlds, and co-founded Imonology in 2010 to make virtual world creation easier and more affordable. Shun-Yun is also dad to two vegetarian kids and has a Ph.D degree in computer science from National Central University.

Polly Huang | Professor at National Taiwan University

Abstract: As the proportion of the multimedia/game traffic over the Internet through wireless and mobile access rises and the world economy recovers slowly, the issue of streaming real-time content cost-effectively is ever more pressing. The key question to address here is how to satisfy more (paying) users given limited resources. Users switch to other services/games because they can't hear/see the content well, not because they detect the fine-grained changes in network loss, delay or jitter, so called Quality of Service (QoS). Over the years, the Internet engineers, although getting very good at designing for QoS, have overlooked the fact that users might not perceive the subtle quantitative difference in QoS metrics to the overall user experience. Towards a user-friendly, therefore economically healthy, mobile Internet, we see the need to measure, understand, and redesign various control mechanisms for quality of user experience (QoE), in addition to the QoS. Using Skype/SILK VoIP service as an example, we show how one (1) measures QoE of calls delivered of different QoS, (2) derives models that translate from QoS to QoE, and (3) exploits the model for a design that pleases the users more under the same resource constraint.

Dr. Julien Lai | Director of the Applied DL team of NVIDIA APAC Region

Abstract: One of the grand challenges of AI is to understand video content. Applications are endless: video surveillance, self-driving cars, live video streaming, ad-placement, etc. Problem is that Deep Learning, which has been boosting modern AI, is computationally expensive. It’s even more challenging when it comes to live stream video. Chip manufacturers are continuously pushing the edge of current IC technology to achieve both high throughput/performance, and high power efficiency. Engineers have also applied techniques such as network pruning, low precision, and model compression, to further accelerate network inference. That is also why our team are building the NVIDIA DeepStream SDK, which simplifies development of high performance video analytics applications powered by deep learning. We have seen successful large-scale deployment of such intelligent video analytics systems, and we see this as an unstoppable trend.

His primary focus now is to apply Deep Learning/Machine Learning techniques for various real-world problems in Computer Vision, Finance, etc.

Prof. Dah Ming Chiu | Research Professor of Chinese University of Hong Kong

Abstract: Due to recent advances in VR and AR technology and applications, more and more videos streamed on-line become 360 degree and 3D. This creates new challenges for video streaming when bandwidth is limited. Besides adapting video resolution to bandwidth, there is also opportunity to adapt what to stream to user attention, or content creator's wish for focus. This opens up exciting opportunities for interesting research. We will describe some existing work (industry seems to be leading the way in this space), and discuss our own efforts.
