As in previous years, NOSSDAV focuses on both established and emerging research topics, high-risk high-return ideas and proposals, and future research directions in multimedia systems. The single-track format encourages academic and industry researchers and practitioners to engage in fruitful and constructive discussions. Out-of-the-box ideas are particularly welcome; NOSSDAV prefers exciting-even-if-incomplete papers over complete-but-boring papers.

The workshop seeks papers in all areas of multimedia systems with an emphasis on the systems aspects. Authors are especially encouraged to submit papers with real-world experimental results and datasets. Topics of interest include (but are not limited to):

  • Virtual reality (VR), augmented reality (AR) and immersive systems
  • Deep learning approaches to improve multimedia delivery and processing
  • Cloud architectures for multimedia coding and processing
  • Wireless, mobile, IoT and embedded systems for multimedia applications
  • Medical, surveillance and autonomous driving multimedia systems
  • Network-distributed media processing
  • Networked GPUs/TPUs, graphics and virtual environments
  • Security in multimedia systems

Submission Process

Prospective authors are invited to submit an electronic version of full papers, in PDF format, up to six (6) printed pages plus one (1) page solely for references in length (double column ACM style format) at the workshop Web site. Authors must prepare their papers in a way that preserves the anonymity of the authors. Please do NOT include the author names under the title. The workshop proceedings will be published by ACM Digital Library.

This year, we introduce the concept of "one-shot revision" for the selection of papers into the program. Papers can be submitted indifferently to any of the two deadlines:

First Deadline

Any paper is welcome. The submission can be accepted or rejected directly, or invited to be revised and resubmitted. Rejected papers cannot be resubmitted to the next deadline. The authors of the accepted papers are encouraged to apply for Artifact Review and Badging (details).

  • Register by: Dec. 11th
  • Upload by: Dec. 14th
  • Notifications on: Feb. 5th (accept, reject or resubmit)

Second Deadline

Any paper is welcome (except the ones that were rejected at the first deadline). The submission will be accepted or rejected. Due to the time constraints, the authors of the accepted papers at this deadline cannot apply for Artifact Review and Badging. Authors interested in a badge should consider submitting their artifact to the Open Dataset and Software Track of MMSys'21.

  • Register by: Mar. 5th
  • Upload by: Mar. 8th
  • Notifications on: Apr. 9th (accept or reject)

Note that the papers invited to be revised and resubmitted are not tentatively accepted. Upon resubmission, they will be reconsidered, however, there is no guarantee of final acceptance.

Online Submission

Review Process

The program committee includes a Review Task Force (RTF) and a Reviewer Committee (RC). The RTF is a group of engaged scientific editors, who ensure the quality of the review process by advising the RC members and leading the conversation, and who write an editorial note on the merits and limits of the accepted papers.

RTF Editors

One editor is assigned to every paper. His/her role is to check the reviews, advise the reviewers on possible ways to improve their reviews, lead the discussion on the paper and to suggest a decision. In the second phase of the review process, a resubmitted paper is assigned to the same RTF editor.

The editor writes an editorial note (or invites a volunteering reviewer to write the editorial note) for every accepted paper. These notes will be published along with the accepted paper in the proceedings. Each editorial note introduces the general idea of the paper in a nutshell and reports the main merits of the paper as identified during the reviewing process.

RC Reviewers

The reviewers are invited to review the paper with regards to the objective of NOSSDAV to get an exciting, possibly controversial, program on novel multimedia and systems directions. High-risk high-reward papers should be encouraged, even if the exploration of ideas is not complete yet.

During the second phase of the review process, a reviewer may be assigned to review a resubmitted paper. If he/she reviewed the paper during the first phase, the reviewer will check whether the improvement brought to the paper addresses the concerns that were raised during the first phase. If he/she did not review the paper during the first phase, the paper will be reviewed as if it was a regular submission.
