Unicast Parameters for GigE Transport Streams
To present the Unicast version of the
Create Output Transport Stream
dialog, disable (un-check)
Multicast
. The entry fields for
Subnet Mask
,
ARP
, and
MAC Address
are then revealed (
).
Other entry fields in this screen are described in
.
MAC Address
If
Multicast
or
ARP
are checked, this field is read-only.
For Unicast or if ARP is disabled (un-checked) this field can be modified to
include a hardcoded MAC address to be used to transport this stream. See
also
MPEG-2 Aggressive Rate
Control
Check this box for output transport streams that require more aggressive rate
control due to severe oscillations from the input bitrate.
Long Delay to support H.264
DPI
Check this box for an output TS when it contains an H.264 program on which
ADs can be placed. Checking this box will allow smooth DPI splicing on
H.264 programs.
Diffserv Code Point
Set value, in the range 0 - 63, to define the differentiated service code point
(DSCP) for the output TS.
The DSCP is a 6 bit field in the IP header that classifies network traffic and
provides QoS. The BNP allows you to configure a DSCP value for IP packets
generated for any type of GigE output transport stream. See also “Using
DSCP” on page 118.
Default = 0
Enable Messaging System
Check this box to allow configuration of Messaging System zones for specific
programs in this transport stream. See “Messaging System Configuration” on
page 60 for information on configuring Messaging Zones.
Stripped Null Packet
Check this box to generate SPTS outputs with no NULL packets to reduce
the average required bandwidth.
This option is only available if
SPTS
is checked.
Note:
When this mode is enabled, the output TS stream is no longer
compliant to MPEG2 TS with respect to PCR jitter and accuracy.
H.264 Alarm Bitrate Level
(Mbps)
This setting can assist in maintaining video quality for MPEG-2 video content
in the presence of other content, such as H.264, which bypasses the BNP’s
transrater. This is done by generating an alarm when H.264 program
bandwidth exceeds the percent of the TS bandwidth specified in this setting.
This option is only available if
SPTS
is unchecked.
Multiple TS
Click if multiple transport streams are used. See “Multiple IP and UDP
Creation” on page 111 for details.
