Mobile TV offerings in focus at NAB

At this year's NAB trade fair, Rohde and Schwarz will present its transmitter and T and M equipment with the focus on mobile TV.

At this year's NAB trade fair from 16th to 19th April 2007 in Las Vegas, Rohde and Schwarz will present its transmitter and T and M equipment on Booth C2927 with the focus on mobile TV.

The company will introduce new functions for the universal R and S SFU broadcast test system.

The R and S SFU supports all internationally common digital TV standards, including terrestrial standards such as DVB-T, ISDB-T, ATSC, and the Chinese standard DTMB (GB20600-2006) as well as DMB-TH.

But the R and S SFU is also suitable for cable standards such as DVB-C and J.83B (up to 1024 QAM) as well as for satellite standards in accordance with DVB-S, -S2 and DirecTV.

As for the transmission of mobile TV, the world's only test transmitter combines DVB-H, T-DMB, ISDB-T, DMB-TH, and MediaFlo on a single platform.

Adjacent-channel occupation with digital and analogue interferers in accordance with the MBRAI standard can also be generated.

But the R and S SFU is also the leading test transmitter in analogue TV as real-time coders are now offered for the internationally used analogue standards B/G, D/K, I, M/N and L.

Also new is an internal video and audio baseband generator for Pal, Secam, NTSC and the R and S ATV-video video test signal library.

Additional test methods in the automotive field are now possible with the DAB, DRM and, soon, ISDB-Tsb options.

Rohde and Schwarz will present new functions for the R and S DVM family for monitoring, analysing, recording and generating MPEG-2 transport streams.

After the major innovations, eg the implemenation of RF signal inputs for the DVB-C, DVB-T-/H, DVB-S, DVB-S2 standards, the ATSC/8VSB and J83/B standards will now be added.

Also the IPTV functionality for the R and S DVM400 has been considerably enhanced, and the digital video measurement system can now monitor up to 300 TV services in a Gigabit Ethernet feed.

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.

To examine MPEG-2- and MPEG-4/AVC/H.264-encoded signals, the R and S DVM-K10 in-depth analysis option has been expanded with real-time buffer analysis.

Moreover, 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 MPEG-4/AVC/H.264-encoded formats.

The R and S DVM-K200 option, which allows a detailed analysis of these signals, makes the R and S DVM family a full H.264 analyser.
