Scope
How to add the payload window in Omnia Enterprise 9s.
Description
the context of Real-time Transport Protocol (RTP), a "payload type" is used to identify the format of the data being transmitted. RTP is a protocol used for delivering audio and video over IP networks, and the payload type helps the receiving system understand how to process and decode the data it receives.
In some AES67 environments the payload type of the output AES67 stream has to be changed. This is necessary if the Omnia Enterprise 9s has to interconnect to other manufacturers using AES67.
For example, Livewire uses 96 for a 48 kHz, stereo audio stream. Dante/AES67 uses a payload of 98 for a 48 kHz stereo stream.
For an AES67 8-channel surround stream a payload of 99 is used.
The right RTP payload value can be found within the SDP file.
Procedure
There are two different alternatives described within this document to achieve the desired behavior.
Alternative 1
Go to your search window on your Windows machine and type in: 'Registry Editor' and press 'Enter'
After the Registry Editor opened go to 'HKEY_LOCAL_SOFTWARE'
Go to the 'Software' folder, press the right mouse button, go to 'New' -> 'Key' and press the left mouse button.
Rename the new 'Key' - folder to 'NfGlobal'
Click on the new 'NfGlobal' folder and move to the right side of your Registry window.
Press the right mouse button anywhere on the right side of the Registry window, go to 'New' -> 'DWORD (32-bit) Value' and press the right mouse button.
Rename the new folder to 'allow_override_lw_payload_type' and press Enter.
Double-click on the new key entry, set the value to '1' and press OK.
Your ouput should look like the picture below:
After you made the changes in your registry editor enter 'services' into your search field from Windows and press 'Enter'
Search for the 'OmniaE9sSvc' service and press 'Restart' on the left of the window.
After the service restarted, open NfRemote and go to any AES67/Livewire output. You should see a 'Payload' window on the right side of every AES67/Livewire output.
Now you can set any payload type to every AES67/Livewire output you want.
Alternative 2
Open an editor like Notepad++, create a new file and type in the following lines:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\NfGlobal]
"allow_override_lw_payload_type"=dword:00000001
Save the file as:
'allow_override_lw_payload_type.reg' anywhere on your PC.
Go to the folder where you saved the file and double-click it.
When the following window opens, click 'Run'.
The upcoming window should be acknowledged with 'Yes'.
When the following window appears, press 'OK' and the value should be added to your registry.
After you executed the steps above, enter 'services' into your search field from Windows and press 'Enter'
Search for the 'OmniaE9sSvc' service and press 'Restart' on the left of the window.
After the service restarted, open NfRemote and go to any AES67/Livewire output. You should see a 'Payload' window on the right side of every AES67/Livewire output.
Now you can set any payload type to every AES67/Livewire output you want.
