and are supplied with all known loudness measurement recommendations, as well as the standard DK-Technologies meter scales. They also provide graphical representation of loudness over time and offer fully adjustable parameters including Gate Level, Reference Level and window timing. They use the same software as our existing products so there are no technical issues when switching between a DK Meter and one of the larger meters in our range (for example the PT0700 series, which provides facilities for loudness logging). What's more, this meter can be updated to accommodate any new standards that might be introduced in the future. Feedback from customers has been incredibly positive. They love the features, the build quality and the modern, ergonomic design. But most of all they love the price, which is $1295.00 in the US and 995.00 in Europe. The DK Meter strengthens our already comprehensive meter range and allows people to use audio meters much earlier in the production process and maintain continuity throughout. Playbox QC. An inside job? asked for more to be bundled into the `box'. So, at NAB 2011, QCBox was added to provide a series of checks of the media prior to going to air. QCBox offers automatic QC, giving an assessment of the technical quality of the media to guarantee successful playout via an AirBox playout server. The checks, applied to relevant media files in a playlist, folder or to selected files, test for the correct duration, continuity (no missing or overlapped frames), blocking, frozen and black frames as well as audio tests, including level and loudness. All test results are stored in a metadata file accompanying the media file. Then, prior to the file's subsequent playout, the AirBox reads the QC metadata and may be set up to skip, show a warning before playing, or play the file depending on the quality results. In addition the audio data from QCBox can be used to automatically control the audio level. These tests are designed to fit with the needs of PlayBox Technology's playout operation. They fit inside the `box' and add no extra space, require virtually zero additional power and are fully automated. QCBox provides the vital QC functions with little, or no, extra operator effort so keeping the overheads and running costs low and still fitting within those ever stretched slender budgets. Pandora Loudness Analyzer andora is a compact and easy-to-read desktop or rackmountable loudness monitor with logging that can be employed at any point in the broadcast chain that requires simple, accurate loudness monitoring. In helping broadcasters address the demands of global loudness standards, Pandora provides a clear, accurate reading of loudness measurements for any SDI video signal with audio. Accepting and analyzing up to eight channels of embedded audio in either SDI or discrete AES streams, Pandora gives the user an accurate reading of loudness measurements (LKFS/LUFS) over a user-defined period of time ranging from 400 milliseconds to 60 minutes. Logs for each session are stored for review at any time. www.wohler.com Today file-based workflows are popular and these fit perfectly with PlayBox Technology's playout solutions, which are inherently file-based. These run a series of real-time functions for ingest, playout, graphics, text, playlists, subtitles, traffic management, etc... Such a collection is often referred to as a `channel in a box' and users have, over the years, continually Wohler T he requirement for quality control grew up in the early days of television and depended on measurement instruments to check the video and audio going to air. This T&M made prefect sense when equipment was analogue and, to an extent, has continued into the digital era, however the needs of the digital file based workflow environment are very different. For example digital signals do not `drift' and the structure of modern digital playout systems is very different to analogue. Add in the huge increase in the number of digital channels now on-air, with many running on slender budgets, and it's clear that a fresh approach to playout QC is needed. P TV-BAY MAGAZINE | 51
