The IP Input Ports will automatically detect the use of RTP, in a packet-by-packet basis. The
9220 will only accept RTP version 2 packets satisfying the following conditions:
• No header extensions (X=0)
• No CSRC list (CC=0)
• Payload type set to MPEG-2 Transport Streams (PT=33)
For more details, please consult RFC 1889, section 5.1. The 9220 does not receive, require, or
process RTCP packets.
Once the configuration information is filled in, click on the Apply button to make it active. If
there are no errors, the port will be created, and the configuration area disappears. If any errors
are detected, they will be displayed at the top of the Apply button. The following errors are
flagged:
•
Error: enter a Source Address or select "Any
for Source but left the Source Address field as 0.0.0.0.
•
Error: X.X.X.X is NOT a multicast
entered an address that is not multicast. Multicast addresses go from 224.0.0.0 to
239.255.255.255.
•
Error: X.X.X.X is NOT a valid unicast
Valid unicast addresses go from 0.0.0.1 to 223.255.255.255, with the exception of the
loopback range of 127.0.0.0 to 127.255.255.255.

one difference.

are attempting to configure an address/port combination that is already in use by another
input in the same Ethernet port. The 9220 is capable of internally replicating transport
streams; just use the other port again in the connection. There is, however, one special
case: if you want to configure an input with a given address/port combination and any
source, and another input with the same address/port combination and a specific source,
you must configure the input with specific source first.

Active IP Inputs Table
Once the input is created, it is added to the Active IP Inputs table, which has Basic and
Advanced views. This table provides a summary of the configuration and status of the input
stream. An example of this table, in the Basic view, is depicted below
