Timing of quality of experience metrics
First Claim
1. A method for quality feedback in a streaming service, wherein at least one media stream (101) is streamed to a client (601), comprising:
- determining (304) a quality feedback value according to at least one quality metric, determining (305) a timestamp relating to said quality feedback value according to at least one timestamp metric, wherein for each of said at least one quality metrics, a corresponding timestamp metric is defined, and wherein each of said at least one timestamp metrics is based on a relative media playback time of said at least one media stream (101), and reporting (306) said quality feedback value and said related timestamp to a server (600).

Abstract
Quality feedback in a streaming service wherein at least one media stream (101) is streamed to a client (601) and a quality feedback value is determined (304) according to at least one quality metric is improved by determining (305) a timestamp relating to said quality feedback value according to at least one timestamp metric, wherein for each of said at least one quality metrics, a corresponding timestamp metric is defined, and wherein each of said at least one timestamp metrics is based on a relative media playback time of said at least one media stream (101), and reporting (306) said quality feedback value and said related timestamp to a server (600). Said relative media playback time is preferably derived from RTP (102) timestamps, from a NPT provided by a RTSP (109), from timestamps of a RTCP or from timestamps of a SIP.

21. A system for quality feedback in a streaming service, comprising:
-
at least one server (600), and at least one client (601), wherein at least one media stream (101) is streamed to said at least one client (601), wherein a quality feedback value is determined according to at least one quality metric, wherein a timestamp relating to said quality feedback value is determined according to at least one timestamp metric that is correspondingly defined for each of said at least one quality metrics and that is based on a relative media playback time of said at least one media stream (101), and wherein said quality feedback value and said related timestamp are reported to said at least one server (600).

23. A server (600) in a streaming service, wherein at least one media stream (101) is streamed to a client (601), wherein a quality feedback value according to at least one quality metric is determined, and wherein a timestamp relating to said quality feedback value is determined according to at least one timestamp metric that is correspondingly defined for each of said at least one quality metrics and that is based on a relative media playback time of said at least one media stream (101), comprising:
means (400) for receiving said quality feedback value and said related timestamp that are reported by said client (601) to said server (600).

24. A protocol to be used in a streaming service, wherein at least one media stream (101) is streamed to a client (601), the protocol defining:
-
at least one quality metric, and at least one timestamp metric for each of said at least one quality metric, wherein each of said at least one timestamp metrics is based on a relative media playback time of said at least one media stream (101). - View Dependent Claims (25, 26, 27)
