Surveying the DTV Landscape with GatesAir
GatesAir has supported the over-the-air industry from its inception nearly 100
years ago, and has lived through every significant game-changing development...

O

ver the past two decades, GatesAir has
managed digital transitions of varying
scale throughout the world.
Every continent and region has its unique
need and challenges. However, the AsiaPacific market stands apart due to its
embrace of different standards. Today's
digital television landscape demonstrates
extraordinary diversity: while DVB-T and
increasingly DVB-T2 remain the most widely
adopted, we see ISDB-T (Japan, Philippines),
DTMB (China) and even ATSC 3.0 (South
Korea) supporting DTV initiatives.
All of these standards will provide
broadcasters with the DTV benefits they seek:
*	 More	programs	and	media	services;
*	 Improved	reception;
*	 The	same	coverage	at	less	power.
More Choices, New Services
First, the delivery of more programs and
services is made possible through the far
more efficient bandwidth of digital streams.
Multiple digital programs can now be
delivered using the same spectrum.
Digital
encoding
and
multiplexing
technologies in the headend play a significant
role in compressing signals ahead of the RF
architecture, while today's advanced digital
modulation techniques provide integrity
through the transmitter. At this stage, a
GatesAir transmission system provides the
capabilities required to prepare the signals for
over-the-air delivery.
Picture Perfect
With digital TV - the days of fuzzy analog
pictures on the edges of the coverage area
are gone forever. However, the perfect
picture and sound immediately drops at the
edge of the coverage area. Today's leadingedge standards - notably, DVB-T, DVB-T2,
ISDB-T and ATSC 3.0 - allow broadcasters
to adopt single-frequency network, or SFN,
architectures that solve this problem.
SFNs
deploy
multiple,
overlapping
transmitters of low-to-medium power
levels, with very low power gap fillers to fill
in the most difficult to reach areas. This
is especially important in countries of
challenging terrain or multiple islands, with
Indonesia being an excellent example.
Lower Operating Costs
GatesAir's Maxiva transmitters currently
provide up to 45 percent efficiency. The
higher efficiency is a substantial driver in cost
savings.
Broadcasters transitioning to currentgeneration transmitters will cut power
usage by at least 40 percent in most cases.
Meanwhile, the continued migration from tube
to solid-state transmitters is further lowering

costs through streamlined maintenance,
improved redundancy and diagnostics, and
less expensive spare parts with greater
availability.
With experience in digital transmissions

worldwide, GatesAir is well-prepared to help
broadcasters managing the most challenging
DTV transitions imaginable.
