Conor Keighrey (@ConorKeighrey) recently completed his PhD in the Athlone Institute of Technology which aimed to capture and understand the quality of experience (QoE) within a novel immersive multimedia speech and language assessment. He is currently interested in exploring the application of immersive multimedia technologies within health, education and training.
With a warm welcome from Istanbul, Ali C. Begen (Ozyegin University and Networked Media, Turkey) opened MMSys 2020 this year. In light of the global pandemic, the conference has taken a new format being delivered online for the first time. This, however, was not the only first for MMSys, Laura Toni (University College London, UK) is introduced as the first-ever female co-chair for the conference. This year, the organising committee presented gender and culturally diverse line-up of researchers from all around the globe. In parallel, two new grand challenges were introduced on the topics of “Improving Open-Source HEVC Encoding” and “Low-latency live streaming” for the first time ever at MMSys.
The conference attracted paper submissions from a range of multimedia topics including but not limited to streaming technologies, networking, machine learning, volumetric media, and fake media detection tools. Core areas were complemented with in-depth keynotes delivered by academic and industry experts.
Examples of such include Ryan Overbeck’s (Google, USA) keynote on “Light Fields – Building the Core Immersive Photo and Video Format for VR and AR” presented on the first day. Light fields provide the opportunity to capture full 6DOF and photo-realism in virtual reality. In his talk, Ryan provided key insight into the camera rigs and results from Google’s recent approach to perfect the capture of virtual representations of real-world spaces.
Later during the conference, Roderick Hodgson from Amber Video presented an interesting keynote on “Preserving Video Truth: an Anti-Deepfakes Narrative”. Roderick delivered a fantastic overview of the emerging area of deep fakes, and the application platforms which are being developed to detect, what will without a doubt be used as highly influential media streams in the future. Discussion closed with Stefano Petrangeli asking how the concept of deep fakes could be applied within the context of AR filters. Although AR is within its infancy from a visual quality perspective, the future may rapidly change how we perceive faces through immersive multimedia experiences utilizing AR filters. The concept is interesting, and it leads to the question of what future challenges will be seen with these emerging technologies.
Although not the main focus of the MMSys conference, the co-located workshops have always stood out for me. I have attended MMSys for the last three years and the warm welcome expressed by all members of the research community has been fantastic. However, the workshops have always shined through as they provide the opportunity to meet those who are working in focused areas of multimedia research. This year’s MMSys was no different as it hosted three workshops:
- NOSSDAV – The International workshop on Network and Operating System Support for Digital Audio and Video
- PV – The International Packet Video Workshop
- MMVE – The International Workshop on Immersive Mixed and Virtual Environment Systems
With a focus on novel immersive media experiences, the MMVE workshop was highly successful with five key presentations exploring the topics of game mechanics, cloud computing, head-mounted display field of view prediction, navigation, and delay. Highlights include the work presented by Na Wang et. Al (George Mason University) which explored field of view prediction within augmented reality experiences on mobile platforms. With the emergence of new and proposed areas of research in augmented reality cloud, field of view predication will alleviate some of the challenges associated with the optimization of network communication for novel immersive multimedia experiences in the future.
Unlike previous years, conference organisers faced the challenge of creating social events which were completely online. A trivia night hosted on Zoom brought over 40 members of the MMSys community together virtually to test their knowledge against a wide array of general knowledge. Utilizing online the platform “Kahoot”, attendees were challenged with a series of 47 questions. With great interaction from the audience, the event provided a great opportunity to socialise in a relaxing manner much like the real world counterpart!
Leader boards towards the end were close, with Wei Tsang Ooi gaining the first place with a last-minute bonus question! Jean Botev and Roderick Hodgson took second and third place respectively. Events like this have always been a highlight of the MMSys community, we hope to see it take place this coming year in person over some quite beers and snacks!
Mea Wang opened the N2Women Meeting on the 10th of June. The event openly discussed core influential topics such as the separation of work and life needs within the research community. With a primary objective of assisting new researchers to maintain a healthy work and life balance. Overall, the event was a success, the topic of work and life balance is important for those at all stages of their research careers. Reflecting on my own personal experiences during my PhD, it can be a struggle to determine when to “clock out” and when to spend a few extra hours engaged with research. Key members of the community shared their own personal experiences, discussing other topics such the importance of mentoring, as academic supervisors can often become a mentor for life. Ozgu Alay discussed the importance of developing connections at research-orientated events. Those new to the community should not be afraid to spark a conversation with experts in the field, often the ideal approach is to take interest in their work and begin discussion from there.
Lastly, Mea Wang mentioned that the initiative had initially acquired funding for the purpose of travel supports and childcare for those attending the conference. Due to the online nature this year, the supports have now been placed aside for next year’s event. Such funding provides a fantastic opportunity to support the cost of attending an international conference and engage with the multimedia community!
Closing the conference, Ali C. Begen opened with the announcement of the awards. The Best Paper Award was presented by Özgü Alay and Christian Timmerer who announced Nan Jiang et al as the winner for their paper on “QuRate: Power-Efficient Mobile Immersive Video Streaming”. The paper is available for download on the ACM Digital Library at the following link. The conference closed with the announcement of key celebrations for next year as the NOSSDAV workshop celebrates it’s 30thanniversary, and the Packet Video workshop celebrates the 25th anniversary!
Overall, the expertise in multimedia shined through in this year’s ACM MMSys, with fantastic keynotes, presentations, and demonstrations from researchers around the globe. Although there are many benefits to attending a virtual conference, after numerous experiences this year I can’t help but feel there is something missing. Over the past 3 years, I’ve attended ACM MMSys in person as a PhD candidate, one of the major benefits of in person events are social encounters. Although this year’s iteration of ACM MMSys did a phenomenal job at the presentation of these events in the new and unexpected virtual format. I believe that it is these social events which shine through as they provide the opportunity to meet, discuss, and develop professional and social links throughout the multimedia research community in a more relaxed setting.
As a result, I look forward to what Özgü Alay, Cheng-Hsin Hsu, and Ali C. Begen have in store for us at ACM Multimedia Systems 2021, located in the beautiful city of Istanbul, Turkey.
