•
Media Loss Rate (packets/s): This field displays the media loss rate. This is defined as the
number of lost or out-of-order media packets per second. This value is measured using the
continuity count in the MPEG header.
•
Delay Factor Max: This field displays the Max delay factor since the last reset. The delay factor
that is acceptable for any particular network varies greatly because of the wide range of buffer
sizes used in STBs.
•
Delay Factor Limit: A user definable value in milliseconds. When this value is exceeded an
SNMP trap will be sent to VLPro providing notification that the stream has exceeded the preset
Delay Factor Threshold value.
•
Media Loss Rate Limit: A user definable value in milliseconds. When this value is exceeded an
SNMP trap will be sent to VLPro providing notification that the stream has exceeded the preset
Media Loss Rate Threshold value.
•
Media Loss Rate Sec Count: This field displays the max Media Loss Rate since the last reset.
Loss of media can cause distorted video and audio. Each lost IP packets can mean as many as
seven MPEG packets being lost. Loss of consecutive IP packets will affect the media more
severely. This value is counted in seconds.
•
Ideal Delay Factor: This field displays, in milliseconds, a calculated value representing the
ideal delay factor, which depends on the stream bitrate and the available bandwidth of the
network (Up to 200Mb/s for the TSM).
