QoS Conditions for VoIP and VoD

Przemysław Dymarski , Sławomir Kula , Nguyen Thanh


This paper concerns quality evaluation of the telecommunication services: VoIP (representing the RT inter- active class) and VoD (representing the MM streaming class). Subjective and objective methods and tools for perceived quality measurement are analyzed and compared. Subjective tests are performed for selected video sequences using the Double-Stimulus Impairment Scale (DSIS) method. Thus the objective algorithms (VQM and VQmon) are calibrated. Speech quality is measured using the objective methods: PESQ and POLQA. Threshold values for network parameters (packet loss rate, delay jitter) are set, that guarantee the acceptable service quality.
