Cisco D9800 Configuration Guide

•
Front Panel (multi-stream unit): From the Main Menu of the D9800 front panel, choose Setup > Outputs > TS
Out > IP > Streams Configuration.
Step 2
In the Maximum Transport Packets/Ethernet Frame field, or the TS/IP front panel menu, enter or choose the maximum
number of transport packets per IP packet (1 to 7).
Step 3
In the Minimum number Packets/Second field, or the Min IP/s front panel menu, enter or choose the minimum number
of transport packets per IP packet (0 or 2 to 1000).
Configuring the Forward Error Correction Settings
Due to the nature of an IP network (occasionally packet loss, packet reordering, and/or stream jitter) it is not
the perfect channel for transmitting broadcast-quality compressed video content. Forward Error Correction
(FEC) developed by the Pro-MPEG forum is a unique technology to enhance the robustness of video traffic
over IP networks. The D9800 receiver supports Pro-MPEG FEC Code of Practice (COP) #3 release2 and
SMPTE-2022, which is based on the exclusive or (XOR) boolean operator applied to a number of data packets.
When a FEC packet is created by performing the XOR boolean operation on a number of RTP packets, a
missing RTP packet can always be reconstructed by performing the XOR operation on the FEC packet and
the remaining RTP packets.
•
FEC = RTP1 XOR RTP2
•
RTP1 = FEC XOR RTP2
•
RTP2 = FEC XOR RTP1
Step 1
Do one of the following:
•
Web GUI (single-stream unit): From the D9800 web GUI, choose Transport Stream > MPEG over IP Output
> Stream tab.
•
Front Panel (single-stream unit): From the Main Menu of the D9800 front panel, choose Setup > Outputs > TS
Out > MOIP > MOIP Streams.
•
Web GUI (multi-stream unit): From the D9800 web GUI, choose Transport Stream > IP Data 1/Data 2 or IP
Data 3/Data 4 Output > Stream tab.
•
Front Panel (multi-stream unit): From the Main Menu of the D9800 front panel, choose Setup > Outputs > TS
Out > IP > Streams Configuration.
Step 2
Click the radio button of the stream you want to configure FEC settings, or choose the ID front panel menu and choose
the stream.
Step 3
Click FEC.
Step 4
From the FEC Mode drop-down list, or the FEC front panel menu, choose an error protection profile.
•
Choose 1D to use the 1D FEC profile. The 1D FEC profile maps the RTP packet stream across columns (matrix
of data packets). The following is an example:
