NAB Show Product Review: Signal Processing

We've now arrived at the doorstep of another big era of change in the television industry, ushering in UHD imaging, wider color gamuts, high dynamic range and virtualization. Plant infrastructures are changing also; this time from SDI to IP. There's one element that won't change though, and that's the requirement for signal processing.

EAS/CAP

DIGITAL ALERTING SYSTEMS (DAS), a division of Monroe Electronics, partnered with TRIVENI DIGITAL on an ATSC 3.0 Advanced Emergency Alerting (AEA) starter kit for TV broadcasters. It combines DAS's DASDEC emergency messaging platform and AEA Content Management with Triveni's Digital GuideBuilder XM signaling and announcement generator, Route/ MMTP encoder and a live source simulator to allow stations to deliver advanced emergency alerts and auxiliary public safety information in both ATSC 1.0 and 3.0 environments.

CLOSED CAPTIONING

COMPROMPTER showcased the latest version of its Caption Central Multi (CCM), featuring a new Speech Engine that provides fast and accurate live voice captioning, with synchronization to the spoken words within two seconds.

EEG introduced the Lexi cloud-hosted automatic speech recognition captioning system which operates automatically in connection with EEG captioning encoders and captioning software to receive program audio, translate it into captions, and provide updating of names, current news events and topics via its cloud environment.

ENCO spotlighted enCaption 3R4 for their enCaption speech-to-text voice technology. It can distinguish between multiple speakers within a single environment, helps to eliminate errors in identifying voices of individuals, saves time and operates without human supervision in live captioning environments.

TELESTREAM announced that its entire suite of captioning and subtitling products now supports IMSC 1.0, the new OTT standard for subtitling and captioning. IMSC 1.0 Timed Text is a requirement for major networks and content distributors standardizing on the IMF file-based delivery format.

VOICEINTERACTION launched the fifth-generation of its Audimus Media system for automatically generating captions for live productions. It provides a cost-effective means for delivering highly accurate captions and ensuring that closed-captioning legal requirements are met.

ENCODERS/DECODERS

AXON DIGITAL DESIGN introduced their eight-channel Synapse NIO440, an Ethernet/SDI bridge that can help broadcasters negotiate the SDI to IP transition. It's software-upgradable and supports S2059 PTP timing and synchronization.

BBRIGHT debuted their UHD-Decode high-bitrate HEVC contribution decoder, which accommodates 10-bit 4:2:2 signals at up to 120 Mbps, and features TSoIP inputs and quad 3G SDI outputs.
