Tackling Ruias Loudne Rollercoaster

Controlling audio loudness throughout the broadcast chain is J nger Audio's speciality. The German company manufacturers sophisticated audio processors that can be supplied as either stand-alone units or rackframe-based modular control systems. All of these processors incorporate the company's proprietary LEVEL MAGIC II adaptive control algorithm, which is compliant with all current broadcast audio loudness recommendations including ITU.1770 Standards (revisions 1, 2 and 3) as well as recommended practices ATSC A/85 (2011/2013), ARIB TR-B32, Free TV OP-59, Portaria 354 and EBU R128.

What makes LEVEL MAGIC II unique is its ability to simultaneously combine an AGC, a Transient Processor and a look ahead' True Peak Limiter for continuous unattended control of any programme material, regardless of its original source. Capable of using any kind of I/O formats, analog or digital, as well as SDI embedded and Dolby encoded, LEVEL MAGIC II is available in a variety of configurations to suit different applications, including the frame-based modular C8000 audio loudness control system and J nger Audio's new slim line family of stand-alone processors.

J nger Audio's Russian distribution partner OKNO-TV has been instrumental in ensuring that key Russian broadcasters have access to the company's ground-breaking technology. In 2012, OKNO supplied Channel One with two frame-based LEVEL MAGIC C8000 systems, which are currently being used for ingest and playout in the broadcaster's automated broadcasting complex. The C8000 systems were chosen because they could simultaneously overcome three main issues - providing EBU R128 compliant loudness control and the transition from stereo to multichannel and integration into the existing playout automation.

Since 2012, Channel One has added more processors and upgraded its existing C8000 systems to the point where it now has units in all areas of its facility. These are providing Loudness Management, multi-channel Dolby encoding including real-time metadata emulation, compliance monitoring and logging.

Dariya Rasimova, Purchasing Specialist at OKNO-TV, says: The Ostankino/Channel One complex uses J nger Audio equipment in all production areas, from material ingest to transmission. The complex has more than 40 J nger Audio devices in total, providing multi-channel audio treatment and control. The reliability and functional richness of J nger Audio modules allows for complex implementation of joint broadcasting schemes such as stereo programs and 5.1 sound.

Rasimova adds that J nger Audio has shown itself to be a reliable partner for Channel One and for other OKNO-TV projects.

This is an important consideration because Russian broadcasters pay as much attention to after sales support as they do to the technology they are buying, Rasimova says. In J nger Audio's case support is always forthcoming and we have no hesitation in recommending the company and its products.

Other Russian companies that have invested in J nger Audio's Loudness Control systems include VGTRK, Russia's 24/7 English-language news channel RTTV HD, Russia's leading entertainment network CTC, GTRK Novosibirsk TV and tele-centre TTC Ostankino, which hires out studios and equipment to the broadcast market.

At Russian state broadcaster VGTRK ( ) 42 frames of J nger Audio's C8000 modular solution have been installed. At RTTV HD, nine new J nger Audio C8000 systems are integrated - all supplied by OKNO-TV. Once again, the ability to comply with international loudness recommendations and the ability to easily integrate into existing infrastructure and automation were key reasons why J nger Audio equipment was chosen.

Alexander Kolosov, deputy director of RT's production complex, says: J nger Audio's LEVEL MAGIC algorithm provides a unique solution to the problem of loudness control and allows us to fully automate this process. We also felt that J nger Audio's solution was able to deal with Dolby technology in a much better way than any other manufacturer's products.

OKNO has also supplied TTC Ostankino with a number of J nger Audio processors including a T*AP Television Audio Processor, an award winning stand-alone unit that is primarily designed for audio control in TV playout and provides Loudness control, Upmix and surround sound processing for up to eight channels of audio (8x1, 4x2, or 6+2).

Andrey Syagaev, leading engineer at Telerent, a company that provides technical support at the Ostankino complex for broadcasters such as Channel One and The TV Channel, says: For the last three years we have been using J nger Audio's C8932 3 RU frames with C8702 lan frame controllers and different C8000 modules for varied schematic solutions. We use it for Dolby E, D and D+ coding and decoding, automatic on-air audio-level control, Dolby metadata insertion and connection with Yamaha and Lawo sound mixers using AES and MADI interfaces.

We also use J nger Audio's recently introduced D*AP 8 MAP Monitoring Processor to monitor different types of audio signal (SDI and AES, PCM and Dolby streams). This equipment is very reliable and also incredibly easy in use thanks to its well-designed web interface and Ember+ control possibilities. Another big plus for us is the support we get from Junger Audio. The company has highly qualified personnel who are always in touch with customers and always ready to help with problem solving.

Peter P rs, J nger Audio's CEO, says providing a high quality level of service and technology is paramount, particularly in geographic area like Russia where there are a large number of broadcasters all competing hard for market share.

Since the break-up of the Soviet Union in 1991, there has been a proliferation in the number of television stations, P rs explains. Today, there
