Opencast is a flexible and customizable video capture and distribution system that facilitates mass videotaping of lectures and classes, an open source alternative to proprietary automated record- ing systems. The current Opencast architecture is highly centralized, integrating very simple recording devices within the classrooms with a powerful central processing system. As a natural evolution of Opencast we describe in this paper a new architecture in which much of the image processing tasks are transferred from the central servers to a new genera- tion of powerful recording devices. Those devices, smart capture agents, contribute to enhance the capabilities of the Opencast systems along different directions: better scalability, lower complexity and lower pur- chasing and operating costs.

The project was born as an initiative of UCBerkeley in 2005 to build a community of institutions interested in creating a system of massive (automatic) record- ing of classes. From this community, a consortium of 13 institutions worldwide, supported by the Hewlett and Melon foundations under the leadership of UC Berkeley and ETH Zurich, managed to develop the first operating version of the Opencast platform. The platform has since evolved into a free software project under the guidance of the Apereo foundation; it arguably constitutes the open source alternative to well established, proprietary automated recording systems. As an example of its success within the realm of Higher Education it is worth mentioning that the largest class recording facility which encompasses more than 350 classrooms, c  Springer International Publishing AG 2018 G.
