Update On Broadcast Test & Measurement
Plumbing the depths of broadcast signals remains a vital part of the broadcast distribution chain. David Kirk gets up to speed on the latest probes and scopes
Over the past 20 years, the entire world of broadcast production, post-production and playout has migrated from panel-per-product dedicated hardware to softwarebased systems running on relatively low cost mass-produced computers. Video and audio are captured as data for processing, archiving and transmission. System crashes are handled by careful design, including integral automated checking for out-of-specification, damaged or missing content. Ideally, a secondary chain is kept on standby in case the primary needs maintenance or suddenly fails. In such a world, who needs test equipment? System integrators for a start, and pretty much everyone else who wants something more tangible than eyeballing a video display or listening to monitor loudspeakers. If the number of new or augmented test and measurement products is any guide, this market sector is not just healthy but expanding. Blackmagic Design – The UltraScope software claims to include all the test and measurement features required during 2D editing and colour correction. Compatible with Microsoft Windows, it is designed for connection to a 24inch monitor and will then display six live scope views simultaneously. Features include a 3 Gbit/s optical fibre SDI interface. A miniature Pocket UltraScope is also available, connecting into the host PC via USB 3 interface. Cel-Soft – Launched version 2 of its award-winning Cel-Scope 3D stereoscopic analyser at NAB. New features in version 2 include additional easy-to-read graphical disparity scales for common parameters such as depth range, rotation errors, vertical missmatches and luminance imbalances. These supplement over 60 different

existing multiple display modes which users can choose from to suit their needs. Cel-Scope3D version 2 also includes the recently introduced depth spectrogram which enables an operator to see if the 3D is within visually comfortable limits based on a timeline history. An active cursor can explore this display with a read-out of both spot disparity and timecode values and the timebase can be set to vary from seconds to hours. CelScope3D version 2 displays can be scaled and arranged as six or eight windows on one or two PC monitors and optionally on a 3D monitor. Left and right channels can be viewed simultaneously t o g e t h e r with depth dynamics. Each display window can be set to show waveform, vectorscope and histogram graphics as well as d i ff e re n c e s in video parameters between each channel. Cel-Scope3D

is available either as a complete turn-key system or as a softwareonly solution to run on a suitable Windows workstation or portable PC. DK Technologies – The PT0740M is an audio-only version of the PT0760M waveform monitor. It offers de-embedding from a single HD/SD SDi input and full StarFish surround sound metering. Analogue and digital inputs and outputs, audio delay and Dolby decoding are provided. All of the products in DK’s PTO700 Series of waveform monitors can now be equipped with the company’s Loudness software, which is based on ITU algorithms and includes the 400 Hz and 1 kHz reference frequencies that are likely to be implemented by broadcast and advertising regulators. Dolby – The DP600 Programme Optimiser provides a wide range of audio tools for loudness correction, audio creation, conversion, and upmixing. It is designed for use in cable, satellite, IPTV, terrestrial TV, radio, and post-production facilities. The DP600 includes intelligent audio analysis and automated loudness normalisation, along with the ability to 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. It also features a newly designed algorithm for upmixing legacy two-channel audio for 5.1-channel delivery. The DP600 also supports many broadcast media file and audio formats.
