complete 4K images after that. One
advantage is potentially better
picture quality, since the higher
quality of the playout material
ensures that the seams between
quadrants remain invisible. In
contrast, separate processing can
lead to unclean interfaces
depending on the quality of
encoding. But the R&S®AVHE100
concentrate a large number of
functions, like carrying out color
subsampling of incoming UHD
signals from 4:2:2 to 4:2:0 in line
with ITU UHD-1, performing HEVC
real time encoding with 8-bit or 10bit color depth, generating UHDTV
multiplex and PSI/SI or PSIP
information or tagging T2-MI
packets with a timestamp pulled
from the GPS signal as required for
terrestrial single-frequency network
(SFN) broadcasting. System
scalability is another benefit of
complete image processing;
customers only purchase the
computing power that they need. A
typical configuration, for example,
is designed for a 4K signal with 60
frames per second and very good
picture quality. The hardware
(processor performance) is tailored
accordingly. Hardware can simply
be added if
requirements such as
higher frame rates
appear.
The transport
stream, generated via
IP or ASI is then
broadcast via terrestrial
transmitters, sent to
satellite uplinks or fed
into cable or IP
networks. Therefore,
Rohde & Schwarz offers
a wide range of DVBT2 transmitters of all
power classes (e. g.,
from the R&S®THU9
and R&S®TMU9
families) for terrestrial broadcasting of
UHDTV programmes. They are capable of
receiving transport streams directly, and the
first installations are in operation. For
emulating test environments for UHDTV
consumer electronics The R&S®BTC
broadcast test centre provided. It is an allin-one solution, since it can simulate any
broadcasting standard and perform both
video and audio analysis at the same time.
Among many other things, the R&S®BTC
has a multistandard modulator equipped for
the most advanced terrestrial, cable and
satellite transmission technologies.
It features a two-path architecture from
the baseband to the RF section, enabling
simulation of complex scenarios such as
MIMO DVB-T2. The R&S®BTC can also be
equipped with an HDMI analysis module
and configured as a complete solution for
set-top box testing. But there are also other
problem areas that need to be tested.
Reception problems annoy viewers and
undermine the image of network
operators. This is why network
operators carry out T&M monitoring in
their coverage areas and take
optimization measures when necessary.
Verified information on coverage
quality is especially indispensable in
metropolitan areas where fading and
echoes are to be expected. The
R&S®ETL TV analyzer delivers this
information. In combination with the
R&S®BCDrive drive test sof
