Abstract:
1. A method of providing a media stream quality signal, the method comprising: monitoring, at a network monitoring device, a media stream transmitted in a media streaming session between a transmitting device and a receiving device via a network; modeling, at the network monitoring device, a video player buffer state of the receiving device based on the media streaming session; determining, at the network monitoring device, a receiving device playback state of the receiving device based on behavior of the modeled video player buffer state; based on the modeled video player buffer state and the receiving device playback state, estimating, at the network monitoring device, a location in the media streaming session of a stream switch event, at which the receiving device changes playback from a first operating point to a second operating point of the media stream, wherein the media stream is an adaptive bitrate stream that has a plurality of operating points; and generating at least one key performance indicator based on the location in the media streaming session of the stream switch event.
