KAISERSLAUTERN, GERMANY — Broadcast media terrestrial transmission pros Rohde & Schwarz, based in Munich, has brought to market a new ATSC translator and re-
transmitter solution for its TLx9 and TMx9evo low-power TV transmitters.
Developed to enhance transmission coverage in areas with challenging geography, such
as steep-sided valleys, the new ATSC translator receives the data input from a parent
transmitter over-the-air and then rebroadcasts it on a separate channel to extend coverage
into these difficult to access areas.
A USP of this R&S tool is its ability to interface to and integrate alongside one of the
market’s highest performance family of low power ATSC transmitters. The all-in-one
translator simplifies coverage extension within ATSC networks, keeping deployment efforts
low. Existing R&S transmitters can be easily upgraded with the new option. Furthermore,
in combination with ASI/TSoIP feeding, the new translator solution can be used to establish
The R&S ATSC translator solution offers enhanced features that make operators‘ lives
easier. With a PSIP edit option, the system has real time detection and display of the
original TSID & PSIP information. If desired, the translator can modify the contents of the
PSIP table including channel number, short name, major channel and minor channel of the
input stream. It can also pass through all Dynamic PSIP Guide information without
corrupting any data. With this feature integrated in, no additional external device is needed
for PSIP editing and deployment is made easier.
In the event of the loss of ASI or RF Tuner input a static picture can be displayed. With the
failure of all inputs it will continuously loop a fully compliant Transport Stream. The static
picture feature can provide a viewer message instead of blue screen. This enables a
fallback mode to stay on air, even without an input signal, helping operators to keep and
inform their viewers in case of an input signal loss.
Also, the translator solution supports ASI Loop Through. With this feature, the transmitter is able to demodulate the RF input signal and it allows the operator to monitor the incoming
signal on ASI baseband level. Via the ASI output port, an ASI test system or ASI transport
stream reader can analyze the decoded RF input signal. This feature helps to simplify the
system design of Translator Stations and provides better information about the origin of
“This new product answers a clear market need and demonstrates the depth of our
transmitter development capabilities,” said Manfred Reitmeier, Vice President of
Broadcast and Amplifier Systems at Rohde & Schwarz. “R&S ATSC translators simplify the
extension of ATSC coverage significantly by making the need for a costly TS feeding
infrastructure to the LPTV transmitter station obsolete and providing an all-in-one solution
for easy deployment.”
