Unlike IP-based workflows that require expensive networking and infrastructure investments,
NewTek’s Advanced IP Workflow uses standard LAN networking to connect your equipment, your
control rooms, and your production facilities, creating a site-wide production ecosystem where
everything sees everything—and any source can be used by anyone for any production.
NewTek’s Advanced IP Workflow employs simplified configuration and management, bi-directional
signal transmission and communication, extensive device networking and access, and
sophisticated encoding and communication methods to enable more powerful, more versatile live
production over IP on a less expensive, less complicated network infrastructure.
NewTek’s Advanced IP Workflow utilizes the Network Device Interface (NDI) protocol to make
every enabled device, connected source, and video signal on your network—production switcher,
replay system, computer, graphics machine, video calling system, etc.—visible and available as a
source and/or destination for video over IP. NDI is also openly available as an SDK to any
customer, manufacturer, or developer who wants to implement it into their products and
workflows to accelerate their transition to IP.
The NDI protocol—the foundation of NewTek’s Advanced IP Workflow—exposes the inputs and
outputs of every networked device, and makes each available as a switchable source. This means
you can access, route, and switch with every camera connected to a switcher in your facility,
every shared computer on your LAN, every output signal from every device—any production
component visible via NDI—increasing your live inputs exponentially without investing in a
higher-capacity switcher or integrating video routing hardware.
Emerging IP workflows marginalize gains by simply replacing SDI cabling with Ethernet
infrastructures. Many methods comprise linear, one-way, point-to-point distribution of a single
video output signal over IP to a single destination. NewTek’s Advanced IP Workflow permits
multi-directional, two-way signal transmission over IP, to and/or from any NDI-enabled device on
your network. This means your switcher can simultaneously send its multiple input and output
signals to the network for transport to multiple NDI destinations, and receive the input and output
signals of every other NDI-enabled device over the network for use as sources.
Common compression technologies for high-quality, low-latency IP transport can consume
upwards of 50% of CPU processing power for a single video stream. NewTek’s powerful codec
enables IP transport that’s so fast and so efficient, a single core of a modern CPU processor can
accommodate multiple simultaneous, high-quality, ultra-low latency video streams over IP while
using lower overhead.
Transporting HD video over IP typically requires high-bandwidth, dual-10Gbit networking to
accommodate just a few sources—demanding up to 3Gbps per video stream in many cases. With
NewTek’s Advanced IP Workflow, it’s entirely possible to access double-digit video streams over
IP on a standard, 1Gbit network connection, with bandwidth consumption generally ranging from
50-100Mbps per video stream.
With NewTek’s Advanced IP Workflow, there is no limit to the number of networked devices that
can serve as sources. And it allows for any combination of resolutions—from a thumbnail icon at
1 fps to, say, 8K video at 240 fps with 64 channels of audio—as long as your infrastructure has the
bandwidth to support it. Accommodating higher resolutions and frame rates may require adding
bandwidth and increasing speeds on your dedicated line or local network, but for most
productions, even GigE can be a starting guideline for multiple sources.
While others in the live video production industry are just now laying the groundwork for
transitioning to IP, NewTek is ahead of the curve. Since our first IT-based video production system
was introduced in 2005, NewTek has been progressing towards IP for 10 years. In that time, our
IT-based video production technology has been installed in tens of thousands of partner devices,
control rooms, trucks, and facilities around the world—and all are fully capable of switching to IP
with our Advanced IP Workflow right now.
Standards and formats come and go in the video industry, making facilities uncertain of which
to adopt. What makes NewTek’s Advanced IP Workflow different is that with NDI, devices are
not bound to a single proprietary specification, resolution, or format, and you are not required to
conform to specific technical criteria. It’s a universal workflow that’s accessible to any current or
future computer-based production component.
