VUE System
- Field
- Description
- MTU Size
- Number of DEPI packets
measured using a standard Maximum Transmission Unit (MTU) of 1500 (7 MPEG
packets) or an MTU of 2000 (10 MPEG packets).
- HTTP Request Timeout (secs)
- Indicates the timeout value
for VUE Controller waiting on VUE Server response to HTTP request in
seconds. For a value of 0, VUE Controller uses the system defined timeout.
The value must be 0-30 seconds. The default value is 5 seconds.
- Clear Buffer Reset Counts
- Clears all the input buffer reset counts on a VUE system. The VUE maintains
a count for each mapping for each MPTS providing content for the Output
Transport Stream(s). VUE increments the count each time the VUE has to reset
the input buffer(s) processing the input MPTSs due to reduced buffer
capacity or surged capacity.
Transport Stream
- Field
- Description
- IP Packet Time To Live (secs)
- Time To Live (TTL) value of the IP packets sent from the Pipes for the
transport streams. The value must be 1 – 255.
- Annex Default Symbol Rate (sps)
- This is the default symbol rate for any output MPTS configured in Annex A.
The EM automatically calculates the output TS rate when Annex A is selected
as the output TS type. The default symbol rate is used for all Annex A
streams when initially selected. Note that this is an EM only setting and
only is used to select the output TS rate.
Input Stream Timeouts
- Field
- Description
- Loss of PSI Multicast Timeouts (secs)
- Detection time in seconds for determining when the input PSI (PAT or PMT) is
considered lost for Multicast streams (typically broadcast/SDV). Value must
be 0 - 21600 (seconds). Default is 600.
- Loss of Input Unicast Stream Timeout (ms)
- Maximum allowable time between packets for Unicast input streams before the
stream is considered lost. Value must be 600 – 6000 (milliseconds in
increments of 200). Default is 5000 milliseconds.
- Loss of Input Multicast Stream Timeout (ms)
- Maximum allowable time between packets for Multicast input streams before
the stream is considered lost. Value must be 600 – 6000 (milliseconds in
increments of 200). Default is 5000 milliseconds.
- Loss of PSI Unicast Timeout (secs)
- Detection time in seconds for determining when the input PSI (PAT or PMT) is
considered lost for Unicast streams (typically VOD). Value must be 0 - 21600
(seconds). Default is 600.
TS Redundancy
- Field
- Description
- TS Redundancy AutoFailback
- Specifies whether AutoFailback to a secondary VUE takes place when a primary
VUE fails.
- Ingress Null Packets
- Specifies whether Null Packets are included when determining whether an
AutoFailback should take place.
Thresholds
- Field
- Description
- Input CC Error Count Threshold
- Threshold setting for input continuity count alarm. This is the number of CC
errors over a 5 second period before a CC error will be indicated. A setting
of 0 disables the CC error checking.
- Output CC Error Count Threshold
- Threshold setting for output continuity count alarm. This is the number of
CC errors over a 5 second period before a CC error will be indicated. A
setting of 0 disables the CC error checking.
- Dropped Egress Packets Threshold
- Identifies the dropped Egress threshold (in 0.00%) ranging from 0.00 –
100.00%. The dropped Egress threshold represents the number of dropped
Egress packets (Δl2tpIn*mpegCnt ΔchOut) compared to the total number of MPEG
packets transmitted (Δl2tpIn * mpegCnt).
- Out of Sequence Packets Threshold
- Identifies the out-of-sequence threshold (in 0.00%) ranging from 0.00 –
100.00%. The out-of-sequence threshold represents the number of
out-of-sequence DEPI packets (∆l2tpOos) compared to the sum of total number
of received DEPI packets (Δl2tpIn) and total number of received session DEPI
packets discarded (Δl2tpDis).
RXD Packet Alarm Enable
- Field
- Description
- Enable Dropped Egress Packets Alarm
- Set when the number of MPEG packets output during the polling period is less
than a configured threshold as compared to the number of inbound DS DEPI
packets received during the polling period. This alarm can be
enabled/disabled.
- Enable Dropped Ingres Packets Alarm
- Set when the number of received DS DEPI packets received during a polling
period is less than a configured threshold as compared to the number of DS
DEPI packets transmitted by VUE during a polling period. This alarm can be
enabled/disabled.
- Enable Out of Sequence Packet Alarm
- Set when the number of DS DEPI packets arriving out of sequence (OOS)
exceeds a configured threshold. This alarm can be enabled/disabled.
Differentiated Service QoS
- Field
- Description
- Video Packets
- This is the output Ethernet DSCP setting for all video packets transmitted
by the VUE system. Range is 0 – 63. Default is 38 (AF43).
- OOB DS/US
- This is the output Ethernet DSCP setting for all OOB packets transmitted by
the VUE system. This is also used for all UEPI packets sent by the RXD and
VARPD packets transmitted by the VUE. Range is 0 – 63. Default is 0
(CS0).
- GCP Communication
- This is the output Ethernet DSCP setting for all GCP communication between
VUE and RXD. Range is 0 – 63. Default is 16 (CS2).
- HA Heartbeat Communication
- This is the output Ethernet DSCP setting for all HA heartbeat communication
between the VUE servers. VUE system. Range is 0 – 63. Default is 48
(CS6).
SDV
- Field
- Description
- Streaming Zone
- Vendor Name
- ERM IP
- ERM Port
- This is the port on which VUE uses to communicate with the ERM. The default
value is 7100 and should not be changed. If changed, may result in loss of
communication with the ERM.
- RTSP Port
- This is the port on which VUE listens to receive messages from the ERM. The
default value is 554 and should not be changed. If changed may result in
loss of communication with the ERM.
- RTSP Hold Time (secs)
- Value in seconds. Value must be 0 or 9 - 300. Default is 30. This is the
amount of time that the VUE will wait for keepalive messages from the ERM.
Expiration of timer is considered a lost connection. If the value is 0, it
disables the keepalive processing.
- RTSP Bandwidth Delta
- Value in Kbps. Value must be 0, 50 - 1,000,000. Default is 1000Kbps. This is
the change in an output stream's bandwidth that causes the VUE to issue an
update to the ERM (to notify the ERM that the output stream (QAM) bandwidth
has changed).
- Reserved Port Mapped OTS Programs
- The OTS reserved program number for VOD Mapping Operations. If set to a
nonzero value, VUE will omit the program number from any VOD Mapping
creations. A value of 0 has VUE use all program numbers.
- DTA Inband PID B/W
- The maximum bandwidth for DTA PIDs in a MTPS controlled by a RTSP session
manager. The range is 2000bps to 1000000bps. The default value is 250000 in
units of bps.
- DTA CDL PID B/W
- The maximum bandwidth for CDL DTA PIDs in a MTPS controlled by a RTSP
session manager. The range is 200000bps (200Kbps) to 10000000bps (10Mbps).
The default value is 500000 in units of bps.
