What fields / parameters contribute to making calculations for the QoE score?

Audio Buffer Overrun

Buffer timing violation causing buffer overrun and is greater than or equal to 100ms.

Audio Buffer Underrun

Buffer timing violation causing buffer underrun is equal to 0 seconds, meaning that the buffer is empty.

Audio Packet Loss

When there are CC errors or incomplete audio frames are received, but the dropout is small (less than 200 msec)

Audio PID Dropout

When there is a dropout (may or may not be accompanied by a CC error) and dropout duration greater than 200 msec.

Audio Syntax Error

When there are no CC errors but there is an error in audio frame decode.
