Eye-to-Eye What's new in broadcast test and measurement by David Kirk D Dolby olby's DP600 Program Optimiser provides a range of audio tools for loudness correction, audio creation, conversion, and upmixing. The DP600 includes intelligent audio analysis and automated loudness normalisation. It can also encode, decode, convert and transcode between Dolby Digital, Dolby Digital Plus, Dolby Pulse, and Dolby E bitstreams, as well as PCM, MPEG-1 LII, AAC, HE AAC, and HE AAC v.2. T he test and measurement product category continues to expand as the broadcast business itself diversifies. Notable recent developments include higher resolution displays and a gradually increasing number of analysers which, having detected a fault, endeavour to fix it. No sign at NAB 2011 of any tablet-based test and measurement equipment but perhaps that is only a matter of time... Agama gama has introduced a new analyser offering continuous monitoring of digital television services. Uninspiringly named the Agama Analyzer, it can be used throughout the delivery chain, monitoring multiple digital TV streams. MPEG-2 and MPEG-4/AVC video for SD and HD are supported. Measured parameters include IP packet jitter and packet loss. Multiple probes can be deployed across a distribution network. A P Phabrix habrix introduced its Rx modular product range at NAB 2011: the Rx2000 2 RU dual screen analyser, the Rx1000 1 RU rasteriser and the Rx500 1 RU half-rack rasteriser. Options include physical layer functions (eye and jitter), separate generator modules, Dolby and an impending ASI decoder. Output resolution is 1920 x 1080 pixels. Each module has its own FPGA so is not slowed down by needing a separate motherboard. D DK-Technologies K Technologies' DK Meter is a compact desk-mountable unit designed offering stereo and 5.1 metering, including loudness. It accepts digital audio inputs and is supplied with ITU, EBU & ATSC loudness measurement recommendations, as well as the standard DKTechnologies meter scales. The meter also provides graphical loudness measurement plus the company's StarFish surround sound display (in model DK2) or vectorscope (DK1). Updates will be available to allow for any new or updated standards. 30 | TV-BAY MAGAZINE R Rohde & Schwarz ohde & Schwarz' Vega Suite software allows off-line analysis of compressed audio and video signals and MPEG-2 transport streams. The software can analyse MPEG-2 transport streams (DVB, ATSC, ISDB) and MXF files as well as H.264, H.264 SVC, H.264 MVC, H.263, MPEG-1, MPEG2, MPEG-4, AVS, VC-1 video formats. MPEG-1/MPEG-2 Audio, Dolby Digital, Dolby Digital Plus, Dolby E, AAC, HE-AAC and MP3 audio standards are supported. Data streams such as teletext, DVB subtitling, closed captioning, XDS and EPG can also be analysed. Batch processing can be used to analyse multiple files automatically. L Leader eader's LG 3860 is a transmission signal generator with optional encoding software supporting a wide range of digital broadcasting standards. An integral encoder and upconverter allow variation of channel frequencies and output levels. The generator can be used as a simple loopback transmitter at a broadcast station. Features include stillimage pattern and audio tone generation plus the ability to play back user-defined transport streams by connecting the LG 3860 to a PC through USB 2.0.
