Memorandum Record of the 2020 JSME Annual Meeting -as a committee member of the web conference-

This is a memorandum record of my experience as a committee member of the 2020 JSME annual meeting, which employed the web conference system because of the COVID-19. Although many web conferences would have held and many researchers and engineers have participated/organized meetings by the time this newsletter is issued, I believe the size of the annual meeting (more than 1000 presentations, more than 2000 participants, and 25 parallel sessions) is still exceptional. I hope that this article helps future organizers of web conferences employing the same system, which is a combination of Zoom and Youtube.

Regarding the broadcasting system for Youtube from Zoom, we employed the direct Zoom system, i.e., we broadcasted using an add-on of the Zoom (please see Fig.1). The alternative option was to use an encoder (please see Fig.2) and in fact this is more functional, but it also means that the system becomes more complex and more settings are required. In other words, when something unexpected happened, we have to check more places and we thought it may take longer time to solve the problem. Considering the nature of “live meeting,” we wanted to minimize a potential risk of stopping the meeting, and therefore, we employed the direct Zoom system.

After training service persons assigned to each Zoom room, who are mostly graduate students, the conference was held on 9/13-9/16. Although there were a number of minor problems, the conference was very successful, and we are happy and proud of that. We appreciate everyone participated in the conference.
