Jünger Audio Processing and 4k video?

Jünger Audio SDI solutions are proofed to perform well with mapped 4K video signals! 4K video can be transported by mapping it into four segments (quad link) to be moved via 4x 3G SDI lines. Typically only one of the SDI lines will carry up to 16ch embedded audio. In case of low latency audio control no further manipulation of the non-audio SDI streams is required. In case of audio control with latency of more then 20 milliseconds, a video delay for A/V time shift compensation should be enabled. In this case all other non-audio 3G SDI streams needs to be delayed the same way. See also our blog entry: Jünger Audio Processing and 4k video

Do you offer replacements for Dolby's DP-Series?

In the past Dolby offered a wide range of professional tools to ensure a smooth and reliable Dolby D, D+ and E production workflow. The DP series included the following devices:

  • DP570 - multichannel audio tool
  • DP571 - Dolby E Encoder
  • DP572 - Dolby E Decoder
  • DP569 - Dolby D Encoder
  • DP563 - Pro Logic II Encoder
  • LM100 - Loudness & Dialnorm Meter

Unfortunately these products have been discontinued by Dolby. As a Dolby premium partner we offer a wide portfolio of products to replace these devices which still are essential tools in a professional Dolby workflow.

Our DAP8 series can be equipped with a Dolby Decoder as well as Dolby D/D+ and Dolby E encoders. Each unit can hold up to two encoders and one decoder. The DAP8 MAP Edition features our unique Dolby Metadata workflow interface and the LM100 functionality is always integrated into all D*AP8 editions. This list shows the direct replacements for DP units:

  • DP570 - D*AP8 MAP Edition w/ Dolby Decoder
  • DP571 - D*AP8 (all editions) w/ Dolby E Encoder
  • DP572 - D*AP8 (all editions) w/ Dolby Decoder
  • DP569 - D*AP8 (all editions) w/ Dolby D/D+ Encoder
  • DP563 - D*AP8 (all editions) w/ Dolby Decoder
  • LM100 - D*AP8 (all editions)

It is important to know that one DAP8 can replace several DP devices at once. For example a DAP8 MAP Edition can be equipped with a Decoder and two Encoders to replace up to six DP devices!

What is the difference between Level Magic and Level Magic II

All currently and at least over the last three years released products and their corresponding firmwares feature the latest generation of Level Magic. This version was sometimes referred to as Level Magic II as we tried to distinguish it from the first generation of this system. The first generation was not capable of working with the international loudness recommendations, as it was released before those modern standards were established. For example, if your Level Magic can be switched to EBU R128, it is a second generation Level Magic. If not, please get in touch to check if a newer firmware is available and if your device has enough processing power for a newer software version. However, for the second generation we decided to stay by the pure name Level Magic as it sometimes becomes unnecessarily confusing for the user and even ourselves.

Is my Jünger Audio device compliant to my local Loudness Regulations?

All our current Jünger Audio Loudness solutions featuring the Level Magic™ algorithm are compliant.

Based on the underlying ITU-R BS.1770(-1/2/3) principle, Level Magic™ provides compatibility with EBU R128, ATSC A/85, ARIB TR-B32, FREE TV OP-59 and Portaria 354.

What is "Level Magic"?

Level Magic is a comprehensive loudness management algorithm designed to ensure compliance with all current worldwide loudness standards. Utilizing the ITU-R BS.1770 loudness measuring principle, Level Magic provides compatibility with EBU R128, ATSC A/85, ARIB TR-B32, FREE TV OP-59 and Portaria 354. Designed to be audibly transparent, Level Magic provides effective loudness control. The Level Magic algorithm responds highly adaptive to the structure of the incoming audio signal and requires only minimal user interaction. The result is free of unwanted artifacts like pumping, breathing or distortion.

An independent brick wall limiter ensures effective true peak limiting by applying look-ahead delay and over sampling to restrict even peaks in between samples.

How to get EXTERNAL CONTROL of Jünger devices?

Basically it doesn’t really matter which physical interface you choose for external control. All our products support both of the interfaces below:

External control via GPI/O

A very simple and straight forward way for external control is the use of GPI/O’s. This makes integration quite easy and lowers the programming and configuration effort needed for set up. On the other hand only a limited set of triggers are available.

Open Control Protocol

With the idea in mind to enable external control systems to access each and every parameter of Jünger equipment, we decided to use an open protocol standard based on the EmBER protocol set. This protocol is becoming an industry standard for accessing individual parameters across different manufacturer’s equipment to unify the operational aspects across a broadcast facility. Ember+ is an initiative out of the Lawo Group and L-S-B Broadcast Technologies GmbH .

You can also operate your Jünger SLIM LINE product remotely by using our Universal Remote Control Panel X*AP RM1.

The X*AP RM1 is the tool of choice for users preferring hands-on control instead of web-based interfaces. It may control a single device or a group of different devices accommodating any infrastructure requirements. Placing the control device apart from the processing devices gives the user the freedom to arrange his or her workplace environment in the most ergonomic way.

Can I analyze and log my loudness measurement data ?

Yes! All Jünger Loudness control devices from all product lines share a neat feature: The gathered measurement data is made available for downstream measurement applications via Ethernet. The LoudnessLogger™ License package allows your J*AM Software an easy way to monitor and analyze all latest Jünger Audio‘s leveling processors. Other than monitoring the true peak and loudness level progression as a live plot, the operating specialist is given valuable statistical information regarding the input vs. output loudness distribution. For an even clearer view of the system performance, all measurements are recorded to a log-file for further inspection.

SOFTWARE APPLICATIONS

What is an iLok key?

An iLok is a USB key with a data chip on used for holding software license data, not to be confused with a USB memory stick, even though they look very similar. In order to run software using the iLok license management system, the iLok USB key with the licenses for the software has to be connected to the workstation while running the software.

What do I need to use the iLok system?

  1. iLok User Account

An iLok User Account is required, which is obtained via a free registration: iLok-Registration The User ID in the registration form on the above registration page, is a unique token referred to as the iLok User ID (sometimes referred to as iLok ID, iLok Account or iLok User Account ID). This is used as your login name on the iLok.com website as well as in the iLok License Manager software. When activating software using the iLok system your iLok User ID is required as the software publisher will deposit the license for your purchased software to your iLok user account.

  1. iLok License Manager

The iLok License Manager software is required. It includes the required software drivers for the iLok system, and offers full management of all your iLok licenses. Download (Mac OS X 32/64-­‐ bit, Windows 32-­‐bit, Windows 64-­‐bit) for free from the ilok.com website: Ilok License Manager Download

  1. iLok USB Key

An iLok USB key is required. There are two versions of iLok USB keys, the original iLok USB Smart key, and the new 2nd Generation USB iLok, both of them are compatible and will work perfectly well. The new 2nd Generation USB iLok holds up to 500 authorizations.
