Patent ID: 7142517

Claim:
A method for using a processor to determine an objective playout quality of a network transmission within a network, said network transmission comprising information in packets for playout according to a playout mechanism, the method comprising: determining a total delay of a packet, said total delay depending on a time of transmission of the packet between two nodes of the network; normalizing the total delay of the packet with respect to a maximum total delay of a group of packets; assigning a delay mean opinion score (DMOS) to the packet based on the normalized total delay of the packet; determining a packet loss rate of the packet, said packet loss rate depending on transmission times of packets transmitted between two nodes of the network being longer than a predetermined time; normalizing the packet loss rate with respect to a maximum packet loss rate of a group of packets; assigning a loss mean opinion score (LMOS) to the packet based on the normalized packet loss rate of the packet; combining the DMOS and the LMOS to determine a mean mean opinion score (MMOS) of the packet; and outputting the MMOS of the packet to a display device.
