Full Description
ETSI TR 101 578 focuses on Quality of Service (QoS) measurements for TCP-based video services wheredownloading and viewing takes place in parallel. In principle the presented measurement approach can be used for allvideo services, where the video is embedded in a HTML context as of video on demand services like e.g. YouTube.Similar applications are also available on social networks.
In the following, QoS parameters to be used for such video service measurements are presented. The underlyingprocedure consists of two phases: first requesting a control script containing among other information a link to thecontent, and second, requesting this content. In the present document, YouTube serves as the default example but thedescribed QoS parameters can easily be applied to other TCP-based video services.
Furthermore, the present document also offers practical guidance for measurement execution and evaluation of HTTPstreaming QoS measurement.
The present document covers the video request and playout of the video. Other services offered by content providerssuch as e.g. uploading video or managing the private account are not covered.
