Are you still watching? Streaming Video Quality and Engagement Assessment in the Crowd

In dieser Veröffentlichung präsentieren wir die ersten Ergebnisse einer deutschlandweiten Studie, in der die Messtechnologie von AVEQ eingesetzt wurde, um die Qualität der Streaminganbieter YouTube, Amazon Prime Video und Netflix zu analysieren. Dabei wurden fünf verschiedene nationale ISPs verglichen. Wir beschreiben Streaming-Performanz in Hinblick auf Ladezeiten und Stalling, aber auch KundInnenverhalten (User Engagement) und die Quality of Experience.
