7.2.1. INPUT MONITOR ENTRY
•
Input State:
Either active or inactive.
•
Num Programs: This is the number of programs found in the input stream.
• Num PIDS: This is the total number of individual PIDs found in the stream.
o Includes all ghost PIDs and Null packets.
•
Input Bit rate:
This is the current bit rate of the input ASI stream.
•
Transport Stream ID: The decimal value for the input stream.
o For example: Corresponds to one satellite transponder.
•
Network ID: The decimal value for Transport Stream Network ID.
o For example: Corresponds to one entire satellite of transponders.
•
Network Name: If available the network name will be displayed.
•
Num Packets/IP: Displays the number of MPEG packets per IP packet.
•
Packet Framing:
Displays the type of framing being used, either UDP or TCP.
7.2.2. MDI MONITOR
•
Delay Factor:
The Delay Factor is the maximum difference measured between the arrivals of each
packet over a one second period. The value shown is measured in milliseconds and represents the
delay factor in the last second.
•
Media Loss Rate (packets/s): Displays the media loss rate. This is defined as the number of lost or
out-of-order media packets per second. This is measured using the continuity count in the MPEG
header.
•
Delay Factor Max:
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.
•
Media Loss Rate Max: 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.
• Ideal Delay Factor: 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).
•
Delay Factor Threshold (ms): 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 Threshold: 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.
• Clear MDI measurements: Click on the button to reset all the MDI measurements recorded.
