CONCEPT FOR DETERMINING THE QUALITY OF A MEDIA DATA STREAM WITH VARYING QUALITY-TO-BITRATE

摘要

Determining a quality of a media data stream including a sequence of data stream sections which transmit different media sections of a media content at quality-to-bitrate levels that vary across the media content, such as within the context of adaptive streaming, is configured to be more effective by deriving, from each data stream section, an identifier for the respective section, and by looking up, for each data stream section, a parameter set from a look-up table by means of the identifier derived for the respective data stream section, so that it is possible to aggregate the parameter sets and to determine the quality on the basis thereof.

主权项

1. A device for determining a quality of a media data stream comprising a sequence of data stream sections which transmit different media sections of a media content at quality-to-bitrate levels that vary across the media content, the device comprising:
an identifier generator configured to derive from each data stream section an identifier for the respective section; a look-up unit configured to look up, for each data stream section, a parameter set from a look-up table by means of the identifier derived for the respective data stream section; and a aggregator configured to aggregate the parameter sets that are looked up for data stream sections that transmit media sections that lie within a test section of the media content; and a quality determiner configured to determine the quality on the basis of the aggregated parameter sets.
