Linear Acoustic prepares the way for ATSC 3.0 at IBC

The LA-5300 delivers loudness control, upmixing, watermarking, coding and monitoring for ATSC 3.0 audio

Integrating upmixing, watermarking, coding and monitoring, Linear Acoustic has developed its latest broadcast audio processor. Easing the transition to ATSC 3.0 audio, the LA-5300 provides loudness control via the Dolby Real-Time Loudness leveller when encoding to AC-4. As ATSC 3.0 adoption grows, support for its additional features such as immersive and object-based audio, interactive consumer control, personalised audio and presentations will be added via software updates. Upmixing from stereo to 5.1-channel audio is provided by the UPMAX ISC algorithm. The LA-5300 can also decode incoming AC-4 streams for confidence monitoring, bitstream analysis and for audience measurement using the optional Nielsen and Verance watermark encoders. Dolby AC-4 encoding plus Dolby Digital and Dolby Digital Plus transcoding to AC-4 are standard, as are four AES-3 inputs/outputs.

Featuring 16 channels of bidirectional AES67 I/O to support SMPTE ST 2110-30 and -31 workflows, the LA-5300’s SDI I/O includes two separate 3G SDI inputs with de-embedding and re-embedding for up to eight audio pairs and optional quad-link 3G SDI for 4K workflows. Dual Ethernet ports are included for both AES67 and networked remote control via the platform- and browser-agnostic web-based user interface. As a further option, 64 channels of MADI I/O are also available.

‘Customers on a strict budget no longer have to accept mediocre television audio processing,’ comments Telos Alliance TV Solutions Group president, John Schur. ‘And they don't need to pay for features like multichannel support, coding or audience measurement capabilities in markets or regions where they aren’t needed or supported.’
