As the media landscape continues to evolve at an unprecedented pace , the demand for innovative , reliable , and cost-effective solutions for live video captioning and subtitling has never been higher .

, a global leader in this field , is set to make a significant impact

at the upcoming International

Broadcasting Convention ( IBC ) 2024 in

Amsterdam . With over 20 years of experience ,

AI-Media is poised to showcase its cutting-edge

technology that is designed to meet the diverse

needs of the European broadcast market . This

editorial will delve into AI-Media ’ s offerings , with

a particular focus on our Alta platform and LEXI

suite and explore why these solutions are set to

revolutionise the industry .

The Heart of AI-Media ’ s Offering : Encoder Pro + LEXI

SDI video isn ’ t going anywhere ; it ’ s the

time-tested solution that delivers consistent

performance and low latency . AI-Media ’ s Encoder

Pro ( HD492 ) will continue to be the key product

to fit into European workflows . The Encoder

Pro is a 1RU caption encoder that allows users

to embed low-latency LEXI captions into their

SDI video in a variety of formats including DVB

Teletext and CEA-708 . The Encoder Pro supports

a variety of trigger inputs to entirely automate the

scheduling of LEXI and on-screen positioning .

The Encoder Pro + LEXI combination is

particularly appealing to broadcasters looking

to streamline operations and achieve significant

cost savings by transitioning from human-based

workflows to automated solutions .

The Alta Platform : Pioneering Virtual Caption Encoding

AI-Media ’ s Alta platform represents the future

of live captioning and subtitling . Designed for

next-generation workflows , Alta offers IP video

closed caption encoding that is software-driven ,

and fully virtualisable . Alta can be deployed

as a standalone virtual machine on VMWare ,

Oracle , Cisco , or Microsoft hypervisors . It ’ s also

available as a pre-packaged AMI for deployment

to customer accounts in Amazon Web Services .

Turnkey physical servers are also available in a

range of channel sizes .

Alta Offered in Two Modes

1 . Alta MPEG TS :

Processes highbandwidth

MPEG

Transport streams and

encodes LEXI captions

as either DVB Teletext ,

DVB Bitmaps , DVB

TTML or CTA-708 .

2 . Alta 2110 : Ingests

a 2110-30 audio

stream and produces

a CTA-708 , OP-47

Teletext , and other

ancillary data packets

in SMPTE 2110 , using

PTP timing and NMOS

IS-05 Connection

Management .

Recent Alta Updates

We ’ re excited to announce that AI-Media ’ s Alta

solution now offers the following new features :

• SMPTE ST 2110-43 Support : Alta

supports outputting live captions in a 2110-43

stream , a popular standard in the European

region . This allows for the transport of Timed

Text Markup Language ( TTML ) within 2110

streams , enabling the sending of non-Latin

character sets in low bandwidth and easy

readability by third-party systems .

• LEXI Audio Dubbing : Set to be

completed before IBC , this feature will enable

the creation of synthetically dubbed audio

tracks based on input audio , which can be

inserted into MPEG TS output streams in one

or multiple languages .

• LEXI Triggering Automation :

Automated control of LEXI upon ad breaks

using SCTE triggers , ensuring captions are

either blocked or resumed instantly based on

the type of trigger sent from an automation

system .

• DVB Subs / Bitmap Caption

Configurability : Users can customise the

appearance of DVB Subs captions , including

font size , colour , and positioning , supporting

a wider range of characters , particularly Asian

characters .

• Cloud Deployment : Alta supports

deployment in Google Cloud , offering an

additional cloud-based alternative to AWS ,

enhancing flexibility and scalability for

broadcasters .

• LEXI DR Support : Alta can run multiple

encoder channels , each capable of outputting

one stream , providing additional flexibility

to have LEXI DR running on multiple Alta

channels simultaneously .

Is Alta for Me ?

Alta is designed from the ground up to

accommodate broadcasters transitioning from

hardware-driven SDI workflows to softwarecontrolled

IP video environments or for

cloud-native operators such as sports franchises ,
