| 摘要 |
This invention relates inter alia to 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). Said relative media playback time is preferably derived from Real-time Transfer Protocol (102) timestamps, from a Normal Play Time provided by a Real-time Streaming Protocol (109), from timestamps of a Real-time Transport Control Protocol or from timestamps of a Session Initiation Protocol.
