Proceedings of the second annual ACM conference on Multimedia systems

It gives us great pleasure to welcome you to the second annual ACM Multimedia Systems conference (MMSys). This conference focuses on multimedia computing and networking, lying at the intersection of digital media and the systems (applications, architectures, networking, operating systems) that handle them. The goal is to cut across a diverse set of computer science subfields in order to achieve a longitudinal perspective on the challenges that multimedia data types present. This provides a unique opportunity to view the intersections and interplay of the various approaches and solutions developed across these domains to deal with multimedia data types. Furthermore, MMSys provides an avenue for communicating research that addresses multimedia systems holistically. Embedded within this year's technical program is a special session on Modern Media Transport (MMT) - Dynamic Adaptive Streaming over HTTP. The papers within the MMT session were chosen from submissions to a separate Call For Papers and selected by a more specialized technical program committee. Also new in this year's technical program is a Dataset track that encourages and recognizes dataset sharing among researchers from both industry and academia. Papers accepted to the Dataset track have their data hosted by the MMSys organization, making them available as a valuable resource for the MMSys research community. This year, there were 41 submissions to the main MMSys track. The main program committee accepted 15 (37%) high-quality papers from this pool. There were 12 papers submitted to the Dataset track. The main program committee accepted 5 (42%) papers with the best methodology and most useful data from this pool. Finally, there were 20 papers submitted to the MMT track. The MMT program committee accepted 5 full and 4 short papers (overall, 45%) from this pool.
