New Developments In Broadcast Test And Measurement
By David Kirk
Test & Measurement (T&M) is one of the dryer aspects of broadcasting compared with such jollities as camcorders, editing systems and video displays. But it is also one of the most important, particularly at a time when the industry makes huge use of data compression. This brief overview gives some idea of the issues currently of primary concern to T&M equipment manufacturers who in turn reflect the needs of their customers. Cel-Soft’s recently announced a logging option for its Cel-Scope3D stereoscopic analyser. Cel-Scope3D is designed for use on set with live inputs as well as for reviewing and playing back 3D media files during post-production. Footage and edits in a wide range of file formats can be viewed and assessed in real time. Disparities can be viewed on 2D or 3D monitors. Anaglyph display, touch-screen control and auto-alarm are all supported. The logging option generates a depth chart automatically, logging against timecode the maximum and minimum depth values employed, together with the range in use. DK-Technologies’ PT0740M is an audio-only version of the PT0760M waveform monitor. Aimed at engineers who do not need a video measurement tool, it offers deembedding from a single HD/SD SDi input and full StarFish surround sound metering. It is complemented by the new PT0730M which offers all the audio functions but without the video input. These meters are compatible with the full range of PT0760 options, providing analogue and digital inputs and outputs, audio delay and Dolby decoding. All of the products in DK’s PTO700 Series of waveform monitors can now be equipped with the company’s Loudness software. DK has also introduced a new feature that offers users the ability to see both peak and loudness metering at the same time, as well as providing dual loudness measurement (for example integrated and instant), while displaying the loudness in a graphical form. Hamlet’s DS900 test and measurement platform is a new way of tackling signal monitoring in busy production or master control area. The current Hamlet DigiScope performs multiple tests simultaneously, displaying up to four windows on an external display. With the DS900, Hamlet has added the capability for four inputs and a multiviewer. On a large screen there can be four windows for each of the four signals. The modular structure of the DS900 means that the inputs can be different formats: analogue or digital, component or composite, standard definition or HD. Linear Acoustic has upgraded its Aero.one audio/loudness manager. Aero.one is designed to manage loudness, upmixing, metadata, signal routing, and audio coding. It allows a broadcaster to match the audio quality of the main path in a cost-effective manner. The Aero.one is available in three versions: dual stereo (2+2), surround sound (5.1), and both (5.1+2). HD/SD-SDI I/O and dual power supplies are now included as standard features Omnitek has introduced V2.1 downloadable software for its OTM and OTR video monitoring and generation systems. Features include a new Manage Disk facility that allows presets, configuration files and images to be readily transferred from one OTM/OTR system to another. This facility also allows the export of log files for examination outside of the OTM/OTR on which they were recorded. Presets and the selected generator patterns are now automatically preserved on upgrade both to V2.1 and to subsequent versions. The HMV-160 modular range of multi-viewers, now available from Oxygen DCT, can display up to 64 images on a single screen or spread the 64 images over up to eight picture monitors. The system comes with signal error detection and monitoring for every input, as well as alarms and diagnostics. HMV-160 multi-viewer systems can handle 3 gigabit/s HD-SDI, HD-SDI, SD-SDI and composite analogue video input signals and provide HD-SDI, DVI-I and HDMI outputs. For monitoring sound, the system can extract the audio from SDI signals as well as having separate analogue audio inputs and outputs with onscreen metering for up to eight channels per video source. Phabrix has announced a new ancillary data analysis option for its range of test and measurement

instruments. This provides detailed analysis of the ancillary data present in a SDI signal. A simple grid layout provides a quick view check of the available vertical and horizontal ancillary data. The packet type is then displayed as present, absent or red if in fault. Simple icons next to the packet indicate the fault. Each ancillary packet available from the grid view can be set to enable logging and then presented together with other information in the events window of the logging menu. Pixelmetrix’s Electronic Couch Potato VQI is a video quality measurement tool that scans all channels, identifies common video impairments such as macro-blocking, tiling and freeze frame, then combines them to a single metric. Results are consolidated across all channels and remote sites Prism Sound’s dScope Series III audio analyser integrates analogue, digital (S/PDIF and I2S), electronic, electroacoustic and Bluetooth measurement capabilities in a single instrument, eliminating the need for signal generation and analysis in external software. Promax has announced a new field strength meter, TV Explorer HD ISDB-T/TB. This can demodulate and analyse television signals broadcast through terrestrial (ISDB-T, ISDBTB), cable (DVB-C Annex A and B) and satellite networks (DVB-S and DVB-S2). Features include MPEG4/H.264 decoding, the ability to record live signals for later analysis, USB file sharing files, TS-ASI input and output, HDMI interface and real-time clock. Rohde & Schwarz’s SFE is a multistandard signal generator supporting all common TV standards plus a number of audio broadcasting standards. It is designed to handle analog or digital terrestrial TV, cable,
