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

摘要

The determination of a quality of a media data stream having a sequence of data stream sections which transmit different media sections of a media content in quality-to-bit rate stages which vary across the media content, for example as part of adaptive streaming, is made more effective by deriving an identifier for the particular section from each data stream section and by looking up a parameter set for each data stream section in a look-up table using the identifier derived for the particular data stream section, with the result that it is possible to collect the parameter sets and to determine the quality on the basis thereof.
