1. Introduction
The DTC-382 TmmXpress software package is designed to create ISDB-Tmm, ISDB-TSB or ISDB-T
signals in the form of I/Q sample files or RF output signals. TmmXpress can be installed by the user
on any qualifying PC, as specified in section 2.
ISDB-Tmm (Terrestrial Mobile Multimedia) broadcasting standard is based on ISDB-T and provides
options to concatenate blocks of 13- and 1-segments up to a total of 33 segments without the need
for a guard band.
TmmXpress allows you to make any combination of 13-, 3- and 1-segments and create signals of
up to 33 segments, specify the modulation parameters, select the sources, add noise, add multiple
channel simulation paths and generate an ISDB-Tmm, TSB or T signal.
The I/Q sample file can be processed by your application or it can be played out through the
StreamXpress.
Note: The TmmXpress functions depend on the installed options, as specified in section 3.
2. Minimum PC Requirements
* Or equivalent AMD processor
3. TmmXpress Software Options
The TmmXpress software requires a valid license to be installed. Without a valid license installed,
TmmXpress will operate in demo mode. In demo mode the option to generate signals is disabled
and a message is shown in the title-bar.
The DTC-382-ISDBTMM is installed as a combination of a DTC-370-ISDB and DTC-380-16MHZ.
The following options are available:
4. TmmXpress Software Installation
The TmmXpress software installation and TmmXpress license installation instructions can be found in
the ‘DTC-382 TmmXpress Installation’ document, which is included in the install package.
