Estimation of video quality of experience on media servers

A method of a media server for estimating a video quality of experience (QoE) of a human viewer of encoded video, comprising:

• obtaining, by a media server within one or more of a first plurality of predetermined synchronized time windows, first coding parameters associated with or or more of a video decoder and a video encoder, the media server including the video decoder and the video encoder;
• determining, by the media server, one or more first QoE scores for one or mon of the video decoder and the video encoder as a predetermined function of the first coding parameters associated therewith;
• estimating, for a first time period of the first plurality of predetermined synchronized time windows, a first resulting video QoE for a human viewer of the encoded video based on the one or more first QoE scores;
• obtaining, by the media server within one or more of a second plurality of predetermined synchronized time windows, second coding parameters of one or more of the video decoder and the video encoder;
• determining, by the media server, one or more second QoE scores for one or more of the video decoder and the video encoder based at least on the second coding parameters;
• estimating, for a second time period of the second plurality of predetermined synchronized time windows, a second resulting video QoE for the human viewer of the encoded video based on the one or more second QoE scores, where a sum of at least the first time period and the second time period represents a duration of the encoded video, and wherein the method further comprises;
• and
• estimating, for the duration of the encoded video, a third resulting video QoE for the human viewer of the encoded video as a predetermined function of one or more of an average and a standard deviation of the one or more first QoE scores and the one or more second QoE scores.

A media server for estimating a video quality of experience (QoE) of a human viewer of video content or communications at a video receiver, comprising:

• a controller operative:
• to control, within one or more of a first plurality of predetermined synchronized time windows, an acquisition of first operational parameters associated with one or more of an ingress network and an egress network over which video content or communications is transmittable, the media server being communicably coupleable to a video sender over the ingress network and communicably coupleable to a video receiver over the egress network;
• to determine one or more first QoE scores for one or more of the ingress network and the egress network as a predetermined function of the first operational parameters associated therewith;
• to estimate, for a first time period of the first plurality of predetermined synchronized time windows, a first resulting video QoE for a human viewer of the video content or communications at the video receiver based on the one or more first QoE scores;
• to control, within one or more of a second plurality of predetermined synchronized time windows, an acquisition of second operational parameters of one or more of the ingress network and the egress network;
• to determine one or more second QoE scores for one or more of the ingress network and the egress network based at least on the second operational parameters;
• to estimate, for a second time period of the second plurality of predetermined synchronized time windows, a second resulting video QoE for the human viewer of the video content or communications at the video receiver based on the one or more second QoE scores, where a sum of at least the first time period and the second time period represents a duration of the video content or communications at the video receiver;
• and
• to estimate, for the duration of the video content or communications at the video receiver, a third resulting video QoE for the human viewer of the video content or communications as a predetermined function of one or more of an average and a standard deviation of the one or more first QoE scores and the one or more second QoE scores.

A media server for estimating a video quality of experience (QoE) of a human viewer of encoded video, comprising:

• a video decoder;
• a video encoder;
• and
• a controller operative:
• to control, within one or more of a first plurality of predetermined synchronized time windows, an acquisition of first coding parameters associated with one or more of the video decoder and the video encoder;
• to determine one or more first QoE scores for one or more of the video decoder and the video encoder as a predetermined function of the first coding parameters associated therewith;
• and
• to estimate, for a time period of the first plurality of predetermined synchronized time windows, a first resulting video QoE for a human viewer of the encoded video based on the one or more first QoE scores;
• wherein a first portion of the one or more first QoE scores corresponds to the ingress network, wherein a second portion of the one or more first QoE scores corresponds to the egress network, and wherein the estimating of the first resulting video QoE includes estimating the first resulting video QoE as a predefined combination of the respective first and second portions of the first one or more QoE scores.
