Press Release : VoiceInteraction selects DELTACAST ST 2110 expertise to move its live captioning platform to IP

Thursday, 21st April 2021

DELTACAST award-winning IP Virtual Card offers an easy-to-deploy solution for developers in the process of migrating their SDI platforms to ST 2110.

Ans (Belgium) & Lisboa (Portugal) - April 20, 2022 – DELTACAST, a leading provider of live video transport & processing solutions for developers in broadcast and ProAV markets, announces another step forward in the deployment of its ST 2110 IP Virtual Card.

VoiceInteraction develops state-of-the-art Speech Processing solutions, producing automatic Closed Captions in real-time for live broadcasts and other media platforms. With high accuracy and low latency, Audimus.Media is VoiceInteraction’s flagship software for the broadcast industry.

Accurate, reliable, and cost-effective captioning – now with live translation on-premises; source video signal encoding to enable clip export with synchronized captions to VOD platforms; HLS playlist creation with WebVTT files to allow stream accessibility in any language, and much more.

While the broadcast industry is accelerating its move to ST 2110, VoiceInteraction was looking for a solution to quickly carry its software from SDI to ST 2110 and reduce the time-to-market.

The DELTACAST IP Virtual Card is a new video and multimedia programming interface allowing the use of 3rd-party computer network cards (NIC) to capture and stream out video. The IP Virtual Card brings in support for video transport as per ST2110-20, audio transport as per ST2110-30, and ancillary data transport as per ST2110-40.

“The fact that the solution can be installed on any machine independent from the NIC card was a key decision factor for us”, explains Renato Cassaca, Chief Software Development Engineer at VoiceInteraction.

The VideoMasterIP SDK provided by DELTACAST makes the integration work easy. The SDK connects the application to the IP Virtual Card through an easy-to-use API (Application Programming Interface) coming with comprehensive documentation and example source code.

“VoiceInteraction seamlessly integrated the SMPTE ST 2110-30 (PCM audio) and ST 2110-40 (Ancillary data) essences natively supported by VideoMasterIP in Audimus.Media”, explain Olivier Antoine, Product Manager at DELTACAST.

Audimus.Media is now ready for deployment in any IP broadcast infrastructure, independently from the NIC card used and will be live demonstrated on VoiceInteraction booth W9711 at NAB 2022 in Las Vegas, NV (USA).


As a Speech Processing Technologies Company, VoiceInteraction bases its practices on Machine Learning and Deep Neural Networks. With a relevant market presence in the Broadcast Industry, VoiceInteraction has solutions for Automatic Closed Captioning, Automated Transcription, and Media Monitoring, available on-premises or cloud-based.

VoiceInteraction will be exhibiting at NAB 2022, booth W9711.
