WALTHAM, MA – March 28, 2023 — Zixi, the industry leader for enabling cost-efficient and highly scalable live
broadcast-quality video over any IP network or protocol and provider of the award-winning SDVP, today announced a
partnership with XL8 that has integrated Zixi into their innovative LiveSubs translation engine to create real-time
subtitles powered by its proprietary state-of-the-art AI technology. LiveSubs allows customers to take their Zixi stream
and generate live subtitled languages on the fly, from the source language into over 70 global language pairs.
Media companies are under increasing pressure to meet the worldwide demand for hyper-localized translated media in
the live distribution space and XL8 takes AI-powered machine translation, specially optimized for media content, to the
next level. Its advanced technology allows significantly more efficient workflows by providing in-line editing, automated
media transcription with time coding, automated subtitling, synthesized voice dubbing, real-time meeting interpretation
including a soon-to-be-released Zoom app, and live subtitling. XL8’s uniquely specialized translation engines have been
built from the ground up utilizing professionally trained, human-perfected subtitles curated from the media industry’s
top content producers. LiveSubs creates subtitles for Broadcasters and Live streams in real-time powered by proprietary
state-of-the-art AI technology.
The LiveSubs Zixi integration means that no additional conversion point is required, and streams can be ingested in real-
time in order to take advantage of XL8’s AI-trained engine. This is essential to the subtitle application as low latency is
one of the key requirements. Leveraging the bandwidth efficiency and reliable delivery included with the integration,
users can offer subtitling services to a wider global audience. Customers using XL8’s LiveSubs can accept as well as
broadcast streams from Zixi enabled live sources and to Zixi Broadcaster target destinations allowing users to deliver
streams at ultra-low latencies with greater bandwidth efficiencies, safely and securely over the internet with dynamic
FEC and ARQ combining to ensure smooth delivery over lossy networks. Users can receive an existing Zixi stream and
feed it to XL8’s LiveSubs engine to generate live subtitle streams for new and existing markets, monetizing content in
markets where the source language is not commonly spoken and facilitating an extended reach in markets where having
subtitles can increase the scope of an event and generate interest from sponsors.
With integrated Zixi protocol support, XL8 customers have access to the industry-leading performance, efficiency,
security and reliability that the Zixi SDVP enables. XL8’s media processing engine connects to Zixi Broadcasters,
leveraging the market-leading Zixi protocol, unlocking valuable features that operations have native access to, including
market-leading network efficiency. The Zixi protocol delivers error-free video, compresses null packets, typical in
broadcast streams, and is also video aware removing repetitive packets resulting in 30% to 50% lower bandwidth
requirements on the network pipe, including a similar reduction in egress costs. Zixi Protocol supports stream bitrates up
to 5Gbps, including jumbo frame support and is 3x more efficient than any other market offering so compute costs and
energy consumption are greatly reduced, and support for ARM Processors realize an additional 50% of the cost and
energy consumption of other compute processors. Zixi supports ~0ms latency with proprietary and tuned congestion-
aware FEC that can be used to achieve latencies as low as transit time with no additional latency for the protocol. The Zixi protocol provides the ability to adjust latency in real time without impact on production streams and is
automatically lowered when all network conditions and QoS health signals are amenable. Zixi has a connection
handshake which multiplexes all streams onto one user-definable input port, and one definable output port that
simplifies firewall setup and reduces complexity by 10x.
The Zixi ZEN Master control plane is integrated to enable users to manage large-scale configurations and orchestrate,
analyze, monitor, and report on live video streams including XL8 deployments, and the Zixi Enabled Network of
customers, integrated hardware and software applications, platforms and service providers standardized on Zixi.
Complex workflows mandate advanced visibility, and Zixi provides insight into packet recovery on the sending side while
including per-PID delivery on the receive side. Live content quality analysis, including ePSNR/eVMAF scores, impairments
detection like frozen video and silent audio, TR101-290 measurement and the widest range of live and trending KPIs
help operations teams understand the health, quality and performance of their live events and linear channels.
“Zixi is the market leader for the delivery of live IP video,” said Janice Pearson, SVP Sales & Strategy, XL8. “With this
integration, our joint customers are able to further monetize their content with highly accurate subtitles and
translations for global audiences.”
“Zixi’s reliability, reach and global footprint helps our customers and partners provide a better quality of service to
subscribers and reach a global audience,” said John Wastcoat, SVP Alliances and Marketing, Zixi. “This partnership with
XL8 is a great example of how the Zixi Enabled Network connects the world of media.”
