DTV Overview

Digital Television (DTV) is an advanced broadcasting technology that has transformed
the television viewing experience.

DTV enables broadcasters to offer television with better picture and sound quality, and
multiple channels of programming.
 A TV set with built-in digital TV tuner to receiver over the air digital television
signals.
 Several regions of the world are in different stages of adaptation and are
implementing different broadcasting standards.
 Transmission of audio and video by digitally processed and multiplexed signal.
 DTV signals are broadcasted to the end user via

Satellite (DVB-S/S2)

Terrestrial (DVB-T/DVB-T2/DAB/DABPlus/T-DMB/ATSC/ATSC-MH/DTMB/CMMB/ISDB-T/Tb)

Software Defined Instrumentation
Software Defined Instrumentation

There are many challenges in meeting the test requirements of
a automotive infotainment system because of wireless
standards evolution, support for multiple wireless standards in
in-car infotainment system.

Flexible and Software configurable instruments are essential
for reducing the cost of the test system, testing multiple
wireless modules functionalities with single hardware, time to
market and test automation.

Designing the test system or automating the infotainment test
system with multiple hardware modules is very complicated
and time consuming.

Software defined instruments helps user to use same hardware
module to test different wireless standards by configuring the
functionality of the hardware through software.

Reduced Time to Market, Complexity of the Test System and
Scalable for future evolution in the wireless standards

VST (NI PXIe-5644R/5645R ) and NI RFSA (NI PXI 5663/5663E, NI PXI5661)Hardware.

Enables testing of multiple digital video and audio standards testing using one NI PXI RF hardware. Ideal
solution for testing multimode Digital Video/Audio SDR.

Real time streaming of the generated waveform using NI RFSG streaming mode. (Typical DTG
testing requires 5 minutes of video to be played in real-time)

Generation of Multiple DVB carriers using single NI RFSG and supports various Transmitter measurements.
