6. Walkthrough: Creating a DVB-T2 T2-MI File
This walkthrough will guide you through creating a DVB-T2 T2-MI file.
- Start T2Xpress application
T2Xpress can be started from the start menu or using the desktop shortcut.
After start-up all DVB-T2 parameters are set to default values.
- Set general DVB-T2 parameters
- Set T2-Frame parameters
Only the fields with light-blue background can be set. The other fields are derived from the
DVB-T2 parameters and are displayed if the parameter set is valid.
- Set Future Extension Frames (FEF) parameters (optional)
- Set Frequencies
Set the carrier frequency of the DVB-T2 RF channel. In case TFS is used, multiple frequencies have
to be set.
- Set PLP Parameters
Modify the PLP parameters and optionally add more PLPs.
To add more PLPs, right-click the mouse in the PLP parameter area and select: Insert PLP.
Alternatively, the Insert key can be used.
To remove a PLP, select the PLP then right-click the mouse and select: Remove PLP. The shortcut
key in this case is Delete.
To navigate through the PLP parameters, use the arrow keys. After selection you can press the
Enter key to modify the parameter. When done, press the Enter key for further navigation.
To modify the PLP’s source, double click on the PLP’s source parameter and select a Transport-
Stream file or the O151 PRBS test signal.
- Check Status Bar
The status bar should indicate: Parameter set is valid. If otherwise, correct the settings.
- Set Output File
Specify the name, location, size and format of the generated T2-MI file.
- Save T2Xpress-Settings
Optionally save the current T2Xpress settings to file by pressing the save button in the toolbar,
or selecting Save File in the menu bar.
- Generate T2-MI File
The generation of the output file can be started by pressing the Generate output button in the
toolbar, or selecting Generate output in the menu bar.
After starting, the progress bar shows the percentage of work done. After completion, the result of
the generation is displayed.
- Play-out of T2-MI File
The generated T2-MI file can be processed by your application directly or it can be played out
through the StreamXpress with a DTA-115 PCI modulator or DTU-215 USB modulator.
To use the StreamXpress for play-out: Start the StreamXpress application, select an appropriate
modulator card, select modulation type T2MI and select the file to be played-out.
