The present document's scope is to provide guidance on OTT video streaming testing approach with a set of minimum desired and most meaningful QoE centric QoS parameters along with recommendations to create a figure of merit quantifying the OTT video streaming session quality@ where possible. In addition@ the set of introduced QoE centric QoS parameters aim to help with the identification of the possible roots of video quality degradation. The present document also offers means to understand aspects related with network and services optimization and troubleshooting@ such as the trade-off between bandwidth usage or controlled throttling and end-to-end video quality. The scope of the present document complements ETSI TS 102 250-2 [i.1] and ETSI TR 101 578 [i.2] while not being as exhaustive@ but rather focused on QoE centric characterization and an end-to-end view on the video streaming session as a whole. Furthermore@ the present document takes into consideration QoE centric evaluation by means of passive@ non-intrusive network monitoring of SSL/QUIC OTT Video Services bitstreams. In addition@ the present document aims to complement the scope of ETSI TR 102 493 [i.3] with respect to QoE models for video streaming integrity as perceived by users.
