Exploiting Advances in Video Technology for Use in Smart Manufacturing

SEMI40 Consortium, 2019

Video content and technology is an integral part of our private and professional lives. We consume news and entertainment content, and besides communication and learning there are many more significant application areas. One area, however, where video content and technology is not (yet) utilized and exploited to a large extent are production environments in factories of the producing industries like the semiconductor and electronic components and systems (ECS) industries. This article outlines some of the opportunities and challenges towards better exploitation of video content and technology in such contexts. An understanding of the current situation is the basis for future socio-technical interventions where video technology may be integrated in work processes within factories.

The Virtual Director Concept: Data-Driven Adaptation and Personalization for Live Video Streams

Proceedings of the 1st International Workshop on Data-Driven Personalisation of Television (DataTV 2019), co-located with the ACM International Conference on Interactive Experiences for Television and Online Video (TVX 2019), , Manchester, UK, 2019

This paper gives a comprehensive overview of the Virtual Director concept. A Virtual Director is a software component automating the key decision making tasks of a TV broadcast director. It decides how to mix and present the available content streams on a particular playout device, most essentially deciding which camera view to show and when to switch to another. A Virtual Director allows to take decisions respecting individual user preferences and playout device characteristics. In order to take meaningful decisions, a Virtual Director must be continuously informed by real-time sensors which emit information about what is happening in the scene. From such (low-level) 'cues', the Virtual Director infers higher-level events, actions, facts and states which in turn trigger the real-time processes deciding on the presentation of the content. The behaviour of a Virtual Director, the 'production grammar', defines how decisions are taken, generally encompassing two main aspects: selecting what is most relevant, and deciding how to show it, applying cinematographic principles.

Collaborating in a Research and Development Project: Knowledge Protection Practices applied in a Co-opetitive Setting

10th Conference Professional Knowledge Management, Data-Driven Knowledge Management workshop, proWM’19, Potsdam, DE, 2019

Organisations participate in collaborative projects that include competitors for a number of strategic reasons, even whilst knowing that this requires them to consider both knowledge sharing and knowledge protection throughout collaboration. In this paper, we investigated which knowledge protection practices representatives of organizations employ in a collaborative research and innovation project that can be characterized as a co-opetitive setting. We conducted a series of 30 interviews and report the following seven practices in structured form: restrictive partner selection in operative project tasks, communication through a gatekeeper, to limit access to a central platform, to hide details of machine data dumps, to have data not leave a factory for analysis, a generic model enabling to hide usage parameters, and to apply legal measures. When connecting each practice to a priori literature, we find three practices focussing on collaborative data analytics tasks had not yet been covered so far.
