On the use of Video-Streaming Technologies for Remote Monitoring of Instrumentation

The paper focuses on the real-time visualization of the instrumentation involved in distance learning of electric and electronic measurements, in order to allow the students to better understand the real behaviour of the instruments. The work presents an integrated architecture enabling the dispatching of videos during the experimental sessions of the Remote Laboratory Distributed on Geographical Network LA.DI.RE. "G. Savastano". The new proposed architecture is able to adapt the video stream characteristics to the available bandwidth on the client side. In order to evaluate the effectiveness and the versatility of the proposed solution different technologies for video streaming have been analyzed and experimentally tested in the laboratory. In particular, the bandwidth occupation and visualization quality have been analyzed using different streaming technologies and changing the frame rate and the light source in a multi-client scenario
