DTC-382 TmmXpress
1. Introduction
The DTC-382 TmmXpress software package is designed to create ISDB-Tmm, ISDB-T
SB
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, T
SB
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.
