10.2 DAB OUTPUT CONFIGURATION
The Appear DAB/DAB+ modulator is a professional broadcast solution for providing digital radio services in cable
networks. It is a high-density modulator capable of DAB/DAB+ transmissions in Band III, from 174 MHz to 260
MHz.
Please note that the DAB modulator does not include a DAB multiplexer, so the DAB
multiplexes (also known as DAB ensembles) must be generated outside the Appear chassis.
10.2.1 DATA CONFIGURATION
The DAB user interface is organized under the "Data" top-level node. The configuration is split into three parts.
One page where the user defines the data/EDI sources and two "output" configuration pages: DAB modulation
and transparently mapped data outputs.
10.2.2 DATA SOURCE
The source page is where the EDI/UDP/IP input stream is configured:
The physical IP port (module) where this EDI stream is present in the
network. All supported IP ports are shown in the dropdown list. If any
VLANs are configured for this port, a separate dropdown box will be used
to select the VLAN used.
The destination IP address of the unicast or multicast carrying the EDI
stream.
The destination UDP port of the unicast or multicast carrying the EDI
stream.
Set the IGMPv3 source-specific multicast (SSM) address. If unchecked, any
multicast source will be allowed
Internal display name of the source. Use the label field as a
convenient way of keeping track of the different DAB multiplex
names.
