#1 Bandwidth Selection:
The CMMB modulation supports 2 bandwidths per channel. With this setting the user can select
between 2 and 8 MHz for the RF spectrum per channel. The CMMB modulation uses 4K mode for 8
MHz channels and a 1K mode for 2 MHz channels.
#2 Tx ID:
The Tx ID represents the transmitter identity in a Single Frequency Network. The value for the TxID
field is ranging from 128 to 255.
#3 Area ID:
The Area ID is used as an ID for the stream coming from the same transmitter but for different
application or region. The value for the Area ID field is ranging from 0 to 127.
3.3.5 DAB(+) Modulation settings
The user can select the DAB modulation and change its parameters if a DekTec card is detected and
licensed for DAB. You can also use the DAB modulation option for DAB+ and/or DMB modulation.
DAB does not use standard transport streams but uses ETI files. Those ETI files can contain multiple
audio and/or (in case of DMB) video streams.
StreamXpress can playout existing ETI files and DekTec offers a command line utility to create the ETI
files.
The ETI utility can be found in the same directory where StreamXpress is installed and is called
DabMux.exe
If the DekTec card is enabled for DAB, use the DabMux application to create valid ETI(NI) files in a
DOS prompt environment. See the DabMux manual on how to do this.
3.5.6 DMB-T/H Modulation settings
If the DekTec Adaptor is licensed to support the DMB-T/H modulation, the user can select the DBM-
T/H modulation and change its parameters.
