Measurement & Monitoring for TV

Ensuring that the audio emitted and transmitted from your broadcast plant meets increasingly strict compliance criteria is a constant challenge for content providers and playout facility operators worldwide. The audio we produce is becoming more complex, surround sound, multi-language, SAP and Next Generation Audio formats, mean that the challenge of maintaining a consistent and high-quality viewer listening experience has never been tougher.

Linear Acoustic AMS Authoring and Monitoring System is a comprehensive solution for real-time authoring, rendering, and monitoring of advanced audio programs for the ATSC 3.0 Digital Television System. The audio system in ATSC 3.0 provides listeners with a personalized, immersive audio experience using Next Generation Audio (NGA) technologies, including MPEG-H. AMS simultaneously delivers advanced audio for ATSC 3.0 broadcasts and 5.1-/2-ch audio for ATSC 1.0 broadcasts.

Linear Acoustic real-time processors such as AERO.8000, AERO.200, AERO.2400, and AERO.20 sit in the final transmission or distribution path where they effectively control unwanted loudness shifts and ensure compliance with ATSC A/85 and EBU R128 standards. In doing so, the control and configuration software package NF Remote provides control and monitoring of all system settings, processing and coding parameters, plus extensive metering of signal presence, processing and coding activity and audio loudness. System status reports physical I/O details along with system, power supply and environmental health. The remote application also delivers remote audio, including 5.1 channels, to the user so that signal quality can be auditioned anywhere network bandwidth permits.

In the world of AoIP, simple confidence monitoring can be achieved using a new set of tools that no longer require extensive cabling of baseband audio to each rackmount monitoring device. The Axia xSelector is a 1RU rackmount Livewire+ AES67 monitor that sits on the AoIP network and provides instant source selection of any available stream to headphones or connected speakers. Comprehensive software tools like Axia iPlay, iProbe and also via the Pathfinder Panel Creator utility, enable the user to select and monitor AoIP streams from their desktop computer or connected Windows device. Pathfinder also gives the user the power to build their own dedicated ‘Soft’ confidence monitor panels, complete with dBFS scale bargraphs, source selector buttons and in-built routing control over connected Livewire+ AES67 devices.
