First you need at least 0.6 mbps of bandwidth to stream the videos. That is your download should do a stable 600k/s at the minimum. The full 8m30s of the sixteen videos selected for you is a total of around 300MB.
Secondly the streaming technology used works best on computers and has been verified using Chrome, Firefox, and Safari. It kind of works on Android devices but the page might need to be reloaded to get started. It doesn't work on older iPads.
Thirdly the technology used is Google Shaka player with MPEG-DASH, or Dynamic Adaptive Streaming over HTTP encoded videos. Two bit rates are available 200bps for the gridview, and 1000bps for zoomed videos. The videos are fragmented and encoded using Bento4. Thank you to the
