NAB Product Preview: Test and Measurement

As equipment becomes increasingly sophisticated and automated, the need for test & measurement products has never been greater. There is only one way for sure to know the quality of your signal: measure it.

Fortunately, today’s test and measurement gear generally does more for less money than the equipment available 10 years ago. Not only that, T&M equipment is also getting smaller and more energy efficient, and IP interfaces on today’s devices let you use the Internet as your test probes.

CONTENT MONITORING

Digital Nirvana will introduce its MonitorIQ Compliance Logging System, a cost-effective logger for audio/video with closed caption/DVB subtitles/teletext and VANC metadata that records up to four channels of HD/SD-SDI, ATSC/QAM, DVBT/C/S2 or eight streams over ASI. MonitorIQ Producer makes it easy to re-purpose broadcast content to the Web, produce podcasts, and save broadcast-ready clips for archiving.

IneoQuest will show a range of IPTV monitoring solutions, including the IQMediaMonitor which monitors and troubleshoots any IPTV/IP video network, and contains software to allow detailed inspection of all video flows across multiple IQMediaMonitor units.

In addition to its monitoring capabilities, the CP546 also allows in-depth analysis of signal, services, components as well as PSI, SI and PSIP table decoding. Combined, these features enable the fast diagnosis of erroneous signals. The CP546 provides remote supervision and monitoring of up to eight DVB-ASI or SMPTE-310 transport streams, and up to 16 IP/Ethernet transport streams.

Video Clarity will debut the RTM Manager, which provides accurate error monitoring/recording for AV quality, lipsync and VANC data for the broadcast, cable or IPTV network facility.

New features for Volicon’s Observer Scout,video network monitoring device include an ASI/Transport Stream Monitoring and Logging system that gives broadcasters, networks, and cable operators the ability to handle MPEG-2 and MPEG-4 transport streams and retains the content and extensive metadata carried within them.

A new loudness monitoring feature for the Observer makes it easy for users to monitor and log audio for multiple stereo and 5.1 channels and comply to both the BS.1770 and EBU Tech 3341/3342 specifications. And the new Observer AC-3 (Dolby Digital) Decoding Option allows operators to capture and log HD/SD-SDI content without the need for expensive external AC-3/Dolby Digital device for extraction, decoding, and embedding.

VIDEO MONITORING

DK-Technologies will spotlight the PTO760M waveform monitor that can test both audio and video. The PTO760M can display parade, waveform, vector, lightning, amplitude, single-line, and levels for up to 16 de-embedded audio channels.
