On Cobham Transmitters, if you are set up for DVB-T operations, you use the Service
Name field to uniquely identify your program.
If you are set up for narrowband operations, you use the Unit Name field to uniquely
identify your program.

About the Receiver End of the Link
13.9.1
Program Numbers
We know that the Program Number is used to uniquely identify a ‘channel’ in a Multiple
Program Transport Stream (MPTS) at the transmitter end of the link.
At the receiver end, we use that same Program Number to ensure we only decode the
elements making up that channel.
13.9.2
Service Names and Unit Names
If the transmitter is using Service Names or Unit Names, then these can be used at the
receive end of the link to uniquely identify programs.
Note: If you type in a Program Number and a Service or Unit name, one takes precedence
over the other. Program Number has priority over Service Name at the receiver.

Setting up Relay Mode
The relay mode allows just the remote service to be transmitted, turning off the local
service.
