R&S®VidChecker: Automated quality control
Automated quality control is becoming ever more important in IT-based production environments. The R&S®VidChecker OEM software offered by Rohde & Schwarz can test compliance with technical and quality parameters and automatically perform any necessary corrections. The software checks technical parameters such as the use of certain audio and video codecs, a user-defined number of audio channels or the existence of specific timecode start values. These checks are based on previously defined minimum requirements or custom standards. Checking the audio and video baseband parameters involves decoding the available coded signals and analyzing them in the baseband. Video testing includes the detection of color bar signals, picture freeze and visual artifacts, for example. In the audio range, R&S®VidChecker analyzes loudness, audio minimum/maximum level, peak level and phase coherence in addition to detecting test tones and audio clipping.

R&S®Video Testers: Video test solutions for any application
Set-top boxes, tablet PCs and smartphones all have analog or digital audio/video interfaces such as HDMI and MHL™ that require in-depth testing. The new Rohde & Schwarz video testers offer everything needed to do so. In addition to pure protocol testing of interfaces, they can perform realtime analysis of media content during application tests on consumer electronics equipment. The product family is made up of the R&S®VTC video test center, the R&S®VTE video tester and the R&S®VTS compact video tester. These instruments cover practically all testing applications in the consumer electronics value-added chain. They also feature an identical modular design and offer maximum flexibility. Thanks to different interface modules and software options, they can be perfectly adapted to the different conditions specific to development, quality assurance and production. One test module each is available for the high-definition multimedia interface (HDMI)

Bavarian Broadcasting Corporation puts innovative R&S®AVHE100 Headend into operation
The Bavarian Broadcasting Corporation (Bayerischer Rundfunk or BR), located in Ismaning, has gone on the air with its first R&S®AVHE100 headend. This means that BR will be proceeding with DVB-T2 trial operation using a headend of the latest generation. TV viewers in and around Munich can now receive the channels “Das Erste” in HD and “Das Erste” and “BR” in SD. Before beginning with broadcasting, experts from BR, RBT (technical consortium of the German public broadcasters) and Rohde & Schwarz integrated the innovative system into the infrastructure. Thorough tests performed by BR and RBT have confirmed the stability and quality of the components used. The R&S®AVHE100 takes a new approach in headend architecture. The R&S®AVS100 high-performance, professional IT servers and specially developed software modules now make it possible to accommodate many previously separate functions such as the encoder, multiplexer or T2 gateway in a single height unit. BR also uses the R&S®AVG100 audio/video gateway from Rohde & Schwarz. The gateway converts conventional broadcast signals such as HD-SDI, SD-SDI and ASI into IP transport streams. To ensure better error protection, the Pro-MPEG CoP#3 Standard is being applied to these streams. The large-scale integration architecture of the R&S®AVHE100 makes it possible to drastically reduce any delay of the headend. This means that viewers tuning into BR to watch sports broadcasts will see their players score points before viewers of broadcasts encoded with headends from other manufacturers.

The compact design makes the R&S®VTS ideal for integration into test setups in manufacturing applications.

The R&S®VTE is a modular, compact platform for use in development and quality assurance.

and mobile high-definition link (MHL) interface commonly used in consumer electronics. The latest module covers analog video and audio interfaces. The instruments are based on the same software, which offers an intuitive and self-explanatory user interface. Great operating convenience and flexibility and a wide variety of selectable functions all make the new R&S®VTx video tester family the reference on the market.

A new dimension of transmitter efficiency thanks to Doherty technology

Rohde & Schwarz relies on Doherty technology for two new-generation transmitters – the R&S®TMU9 medium-power transmitter and the R&S®THU9 high-power transmitter. This technology allows both transmitters to achieve a level of energy efficiency that was impossible in the past. Doherty technology is based on an architecture developed in 1936 by William H. Doherty. The basic principle involves splitting signal amplification between

two paths. The advantage is that the average signal is amplified in the carrier amplifier, and no power margins have to be reserved for the peak signals in this path. The peaking amplifier is only required when the signal power peaks. This saves energy in both the carrier and the peaking amplifier. Broadband amplifier design Because the Doherty architecture does not require any additional modules, the mean

time between failure (MTBF) of the amplifiers remains unchanged. Rohde & Schwarz has revolutionized Doherty technology with its R&S®TMU9. For the first time, the amplifiers have a broadband design while still making use of the basically narrowband Doherty architecture. Even in large transmitter networks that use many different frequencies, it is now possible to effectively manage the spare parts inventory.
