The constant connection must be at least 3mbps to view.
Collegerama must have a fixed network connection of 3mbps in order to view the recording properly. The platform is not set up like YouTube, which is a flat video and the bandwidth is constantly monitored and the correct video is chosen to play it properly. Collegerama works with several videos (speaker, presentation and, for example, smartboard), which are all available separately, so that the viewer can choose which video the big / small one wants to have on the screen.
If we offer multiple bandwidths (which is possible, it only costs much more storage), then a number of functionalities such as – at the moment – accelerated playback, which will benefit the students, will lapse. We try to give 95% of the students the guarantee to view recordings. Even though we find it very annoying for the students who experience this problem.
It is very difficult for us to determine where exactly the problem lies, because there can be so many issues after the network exit of TU Delft. In addition, we see no problems with the ICT networks department in the Collegerama server park, which is monitored 24/7.
