Monitoring Quality of Experience (QoE) at Audio/Video (AV) Endpoints Using a No-Reference (NR) Method

摘要

Monitoring quality of experience (QoE) using a no-reference (NR) method. An uncompressed audio/video (AV) stream is received from output of a device under test (DUT), where the uncompressed AV stream includes content that is known to be devoid of a set of one or more AV artifacts. At least one of the set of AV artifacts is automatically tested for its existence using a no-reference method that does not use a comparison to an input reference AV stream. Upon determining that there is an AV event representing one of the set of AV artifacts based on the automatic testing, a video clip that includes the AV event is automatically generated. The automatically generated video clip is stored.
