At this year's NAB trade show in Las Vegas from 24th to 27th April, Rohde and Schwarz will present a product portfolio with the theme "broadcast on the move".

Different standards for bringing TV to mobile user equipment are emerging around the world.

The transmitter and T and M equipment from Rohde and Schwarz addresses new future-oriented standards such as DVB-H, MediaFLO and T-DMB.

The company will showcase its solutions in central hall, Booth C830.

The successful all-purpose R and S SFU broadcast test system was developed for all internationally important digital TV standards such as 8VSB/ATSC, J.83/B, DVB S2, DVB-S, DVB-T, DVB-H, DVB-C, DMB-TH/-T2, T-DMB, DAB and DirecTV.

A new analogue interferer and an interferer management option now complement the R and S SFU to handle transmission simulation.

By using these options, the effect an analogue TV interference signal has on the useful digital signal can be easily simulated.

The different instruments of the R and S DVM family are used to monitor, analyse, record and generate MPEG-2 transport streams.

Now this family has also been enhanced with new functions.

The R and S DVM-K12 template monitoring option is an important addon that allows automatic monitoring of undesired changes in the transport stream and the programs it includes.

The R and S DVM K10 in-depth analysis option is expanded by real-time buffer analysis.

This function supports not only MPEG-2 but also the new compression standard MPEG-4/AVC/H.264.

Plus, the R and S DV-H264 transport stream library is now available for the R and S DVM400, R and S SFU and R and S DVRG.

The library includes video content in different formats which are MPEG-4/AVC/H.264-encoded.

The R and S FSH3-TV from Rohde and Schwarz is a handheld TV analyser that is suitable for all digital and analogue TV signals.

Although analogue terrestrial TV transmitter and cable networks around the world are being converted to digital, analogue T and M equipment is still required, especially during the transition phase.

Rohde and Schwarz is meeting this demand by enhancing the scope of functions of the successful R and S FSH3-TV; the analyser now provides important analogue measurement functions such as FM deviation measurement for sound carriers.

Its mobility makes the R and S FSH3-TV especially useful for servicing new installations and maintaining or repairing TV cable network or transmitter components.

With the R and S UP 300 and R and S UP 350 audio analysers, Rohde and Schwarz is adding two new economical and compact audio analysers to the R and S Smart Instruments family.

The R and S UP 300 covers a frequency range from 10Hz to 80kHz.

Its analogue inputs and outputs are dual-channel.

The R and S UP 350 additionally features digital audio interfaces with sampling rates from 32 to 192kHz.

These interfaces expand the scope of applications to digital audio protocol and sampling rate measurements.

The R and S SV8000 transmitter platform for digital TV standards (ATSC, MediaFLO, DVB-T/-H) will be showcased for the first time.

It has been designed for TV power up to 400 W in the UHF band.

Like their predecessors of the R and S SV7000 series, the new transmitters are highly modular and flexible.

Standby configurations, remote control interfaces and other characteristics typical of Rohde and Schwarz, such as automatic digital precorrection, are of course also available for this transmitter family.

As regards sound broadcasting, Rohde and Schwarz will present its new R and S SR8000 FM low-power transmitter for output power from 100W to 1kW.

The transmitter is equipped with a digital exciter; occupying no more than four height units, the R and S SR8000 is highly compact.

All functions are integrated in a single unit.

The transmitter is remotely monitored and controlled via SNMP and a web interface.

Rohde and Schwarz offers a DVB-H inserter to complement the R and S DIP010 data inserter, providing the playout technology required for transporting multimedia data.

For this purpose, the H.264 video encoder for DVB-H comes with a variable bitrate.

The statistic multiplex principle is implemented: With DVB-H, several TV programs with different datarates are transmitted via one channel.

Sequences with strongly moving pictures require a higher datarate than picture contents that move less.

The H.264 video encoder harmonises these different requirements, ensuring optimum use of the transmission channel and allowing more programs per channel to be transmitted.
