A method for data processing, comprising - receiving first data from a first network, - the first data comprising feedback of a plurality of users on a quality of an audio and/or video content, - the feedback of the plurality of users on the quality of the audio and/or video content being provided by the plurality of users via a respective remote control or via a user interface of a respective set top box by selection from the following quality impairment categories: Audio artefact: Audio data are out of synchronization with video data; Audio artefact: Clipping audio is received; Audio artefact: No sound is received; Video artefact: No picture is received; Video artefact: Blocky video is received; Video artefact: Video with lines is received; Artefact: No interactivity is available; Artefact: Interactivity is corrupted; - receiving second data, - the second data being automatically determined by or in components of the first network or by or in user-located equipment, which equipment receives the audio and/or video content, - the second data are being based on the quality of the audio and/or video content, - the second data indicating that an alarm needs to be initiated due to deteriorated quality of the audio and/or video content, - evaluating, at a server, the quality of said audio and/or video content based on the first data and on the second data, - the evaluated audio and/or video quality of said audio and/or video content initiating and/or triggering and/or determining an urgency of the alarm, wherein the type of the alarm is related to the evaluated audio and/or video quality, wherein no urgency is triggered, if the first data indicate no urgency, wherein the first data indicate the urgency of the alarm, which alarm is based on the second data, wherein, if packet loss is recognized by the server in the second data and at the same time the server does not receive any first data comprising user generated reports on bad or deteriorated quality, it raises an amber alarm, whereas, if the server recognizes packet loss in the second data and receives first data comprising user generated impairment reports within the same timeframe, it raises a red alarm triggering an immediate event, wherein the amber alarm corresponds to an alarm without urgency and the red alarm corresponds to an alarm with urgency. - receiving first data from a first network, - the first data comprising feedback of a plurality of users on a quality of an audio and/or video content, - the feedback of the plurality of users on the quality of the audio and/or video content being provided by the plurality of users via a respective remote control or via a user interface of a respective set top box by selection from the following quality impairment categories: Audio artefact: Audio data are out of synchronization with video data; Audio artefact: Clipping audio is received; Audio artefact: No sound is received; Video artefact: No picture is received; Video artefact: Blocky video is received; Video artefact: Video with lines is received; Artefact: No interactivity is available; Artefact: Interactivity is corrupted; Audio artefact: Audio data are out of synchronization with video data; Audio artefact: Clipping audio is received; Audio artefact: No sound is received; Video artefact: No picture is received; Video artefact: Blocky video is received; Video artefact: Video with lines is received; Artefact: No interactivity is available; Artefact: Interactivity is corrupted; - receiving second data, - the second data being automatically determined by or in components of the first network or by or in user-located equipment, which equipment receives the audio and/or video content, - the second data are being based on the quality of the audio and/or video content, - the second data indicating that an alarm needs to be initiated due to deteriorated quality of the audio and/or video content, - evaluating, at a server, the quality of said audio and/or video content based on the first data and on the second data, - the evaluated audio and/or video quality of said audio and/or video content initiating and/or triggering and/or determining an urgency of the alarm,
