This section describes how to use the Stat Mux Dejitter Groups window to set up 

SMDGs on GQAM modulators that receive multiplexed sources. You can set up a 

maximum of 16 SMDGs on a GQAM modulator — one SMDG for each RF output 

port on the GQAM modulator. Each SMDG can accommodate a maximum of 60 

sessions. 
Important! Setting up an SMDG enables the GQAM modulator to appropriately 

process multiplexed sources. Failing to set up SMDGs on GQAM modulators that 

receive multiplexed sources may result in tiling (macroblocking) of the video on 

DHCTs. 

 

Software Required 
Before you begin, make certain that you have the following software installed on 

your system: 

 

GQAM software release 4.0 or later 

 

DNCS SR 2.7/3.7/4.2 SP2 or later 

Information Required 
You will need your network map and the following information: 

 

The input ports that receive the multiplexed source (ASI inputs, Ethernet inputs, 

or both) 

 

If a GbE port is used for multicasting, the destination multicast IP address (IP 

multicast address) for the GQAM modulator 

 

If a GbE port is used for unicasting, the destination UDP port number on the 

GQAM modulator that receives the source 

 

GQAM output port number that modulates the source onto the network 

Note: All of this information should be recorded on your network map. However, if 

it is not, contact your system administrator to obtain the information.
