SMD 989

Alias Permits entry of friendly name or description
Receive Enabled
Disabled This setting allows the user to enable or
disable these input stream settings.
Physical
Connector Port 1
Port 2 The physical connector on the MPEG/IP card
that will be used to receive the input.
Routing Mode Multicast
Unicast Multicast setting allows the unit to receive
multicast streams. Multicast streams
originate from the IP range 224.0.0.0
–
239.255.255.255. Unicast allows the unit to
receive unicast streams. Unicast streams
originate directly from a source device.
Destination IP 224.0.0.0
–
239.255.255.255
This setting is only available when receiving
a multicast stream. This address is the IP
address the source device is sending to.
Destination Port
0
– 65535
This is the UDP port the source device is
sending to. This is the only setting required to
receive a unicast stream.
FEC Enabled
Disabled Enabling FEC (Forward Error Correction)
tells the SMD 989 to look at Destination Port
+2 and Destination Port +4 for a SMPTE
2022 FEC Matrix.
RTP SSRC Enabled
Disabled Enabling RTP SSRC allows the SMD989 to
filter the input by the user defined value. Only
streams containing the user defined value
will be received by the SMD989.
SSRC Filter Value
0
– 4294967295
The Filter Value the SMD 989 checks for
before receiving a stream with RTP SSRC.
Buffer Mode Size (KB)
Delay (ms) Allows option to set buffer mode to Size in
KB or Delay ms
Buffer Size (KB)
10
– 4000 KB
This setting determines how much data is
received before the SMD 989 starts
decoding. Increasing this value will allow the
SDM 989 is receive streams on networks
with high network jitter. Increasing this value
also increases the latency of the SMD 989.
Buffer Delay (ms) 1
– 4000 ms
The buffer delay setting allows the buffer size
to be set by delay time. The Buffer delay time
will be determined by the input data rate.
IGMP Filter Mode Exclude
Include Used on networks supporting IGMPv3. If this
setting is set to
Exclude any streams
originating from the user defined IP
addresses will be rejected. If this setting is
set to
Include any streams originating from
the user defined IP addresses will be
received.
With the SMD 912(A) the input buffer size is settable at a range from 1 to 4,000 KB. The larger
the buffer size, the more latency will be created in the system. The tradeoff is a potential for IP
jitter and dropped packets. It further permits setting an input buffer delay of 1 to 4000 mS.
The advanced settings allow source specific multicasting using IGMP v3 joins. The filter can be
set to exclude or include. IGMP addresses can be added and removed by clicking the
