A próxima evolução do NDI®

April 08, 2018 by Dr. Andrew Cross and Steve Bowie

Desde o início, a missão da NewTek poderia ser resumida em um princípio imperativo: levar para o vídeo a voz dos contadores de história. Estamos convencidos de que computadores, software e redes são os três pilares da próxima geração de ferramentas de vídeo, não apenas para mercados de alta qualidade, mas para qualquer um que queira produzir um programa ou fazer stream de sua equipe, classe ou congregação e se divertir enquanto faz isso.

Video revolutions start in basements and garages wherever creative programmers have great ideas (we know, because we started there, too!) We want them to succeed. When they win, we all win. NDI® is where our commitment to this vision becomes reality.

We could have kept NDI to ourselves. Instead, we made it both incredibly easy to implement and free to sell. Thus we were gratified but not surprised to see hundreds of great new products appear as if overnight that take advantage of NDI’s outstanding A/V interchange features.

To underscore how strongly we feel about this, we even helped our competitors achieve their goals: We released our NDI PTZ cameras, but we also assisted Panasonic, PTZ Optics, Lumens, Marshall, and others to bring their NDI products to market. We’ve made NewTek-brand NDI converters, but helped BirdDog create theirs, too. And we give away, completely free of cost, our richly powerful suite of NDI Tools – to enable developers and end-users alike to immediately multiply the benefits of their investments.

We’re very proud of NDI. It’s what results when a video software company designs an IP protocol. NDI checks all the important boxes for production, but doesn’t paint you into a corner. For example, NDI-SMPTE2110 interop is fully functional. Likewise, we anticipate that upcoming protocols in various stages of development by hardware-focused companies will be equally complementary to and compatible with NDI.

We want to sincerely thank the community for making NDI the world’s most successful IP standard for video production. Without thousands of companies who joined hands with us, more than ten million people would still be chained to HDMI and SDI. While this latest build is dubbed version 3.5 (full integer updates occur at IBC on NDI’s anniversary), it is extremely feature packed and delivers massive benefits for NDI developers and customers alike.

Changes to NDI Applications and Drivers

NDI Scan Converter

The new version of NDI Scan Converter provides vastly improved image quality and much, much more. The GPU is now used to capture the screen, and handles the lion’s share of color conversion, processing and NDI transmission. You can now capture all of your system’s desktops in real-time, at full 60Hz and with almost no CPU usage. (Note: This version of Scan Converter relies on the latest DirectX 11 API, thus requires Windows 8 or better.) Choose which audio source accompanies your screen capture, including system audio. Now you can play a computer game or display a PowerPoint presentation with audio (with no impact on frame-rate) and supply it as an NDI source. Scan Converter now fully supports webcams, too. Stream games with audio, and overlay your webcam on the stream while supplying voice-over with a high-quality mic. Send PowerPoint to your audience on Hangouts, Zoom Media, Skype, or GoToMeeting (see NDI Virtual Input), and use your webcam to talk to them. NDI Scan Converter now provides ‘region of interest’ support, so you can capture video directly from a YouTube page.

NDI Studio Monitor

Seria difícil exagerar a importância deste "pequeno gigante". Sinalização é um campo de vídeo abrangente e importante, e o Studio Monitor tem tudo para cobri-lo. O conjunto para virtualmente todos os programas agora inclui várias telas de vídeo; saguões, fachadas de prédios e outdoors exibem telas gigantes, e assim por diante. Fornecer estas fontes por cabeamento análogo foi sempre impraticável, os custos de hardware de SDI são proibitivos e as limitações de distância do HDMI impedem que sirva como uma alternativa confiável. O IP é, claro, a solução perfeita: onipresente, confiável e barato.

Need to update the display on a remote screen? NDI Studio Monitor now provides an integrated web server; just scan a QR code on the display to turn your mobile device into a (password-protected) remote control. What’s more, multiple instances of Studio Monitor running on the same machine can be independently controlled. Even when you have lots of different computers running Studio Monitor, they all ‘see’ each other over P2P, giving you complete control from any point on your network!

Uma adição igualmente radical e valiosa ao Studio Monitor permite sobrepor títulos e gráficos (até mesmo vídeo de movimento pleno) na tela. Atribua uma sobreposição exclusiva para aparecer no vídeo em seu lobby e aplique algo diferente para sua sala de exposições. Ou use o recurso de sobreposição para fornecer imagem em saída de imagem. Cada instância do Studio Monitor agora pode escolher qual dispositivo de som usar para reprodução e em qual monitor de vídeo sua saída deve aparecer (ou quais monitores deve incluir). Você pode até mesmo definir o Studio Monitor para abrir na inicialização do computador para que várias instâncias, todas corretamente configuradas, sejam abertas automaticamente. Compre um ou dois NUCs para criar de modo fácil e barato várias saídas de 4K controladas remotamente.

Better support for joysticks and keyboard shortcuts for PTZ control round out this phenomenal upgrade.

Entrada virtual NDI

Assign NDI video sources as inputs to anything that supports webcams (including GoTo Meeting, Skype, Hangouts, Zoom Media, and much more!) NDI Virtual Input fully supports 1080p60 or even 4K at full frame-rate, and even allows you to modify audio levels for different application requirements.

VLC Media Player

Esta nova versão agora é compatível com VLC 3.0 e 2.x. O controle PTZ virtual é integrado, permitindo fazer pan e zoom em torno da saída VLC exibida no Studio Monitor, como se você estivesse controlando uma câmera PTZ de verdade. O suporte a formatos de vídeo foi melhorado, assim como os carimbos de hora e mais.

Adobe CC drivers

O novo driver é compatível com a última versão do Adobe CC, ao mesmo tempo que oferecer melhor qualidade, suporte de cor de ponto de flutuação e mais.

NDI HX Drivers

The NDI HX drivers are now integrated into NDI tools to make things quicker and more convenient. The drivers feature many optimizations, bug-fixes and improved support for complex network setups. In addition, hardware acceleration support has been upgraded.

Changes to the SDK

Tornamos todo o SDK mais fácil de usar. As funções ficaram mais fáceis de entender, mas totalmente compatíveis no sentido inverso. O novo Guia de Primeiros Passos do SDK acelerará o processo de aprendizagem para iniciantes no ecossistema NDI.

Changes to the Protocol

Really, NDI itself has been completely transformed ‘under the hood’, including truly massive optimizations to the underlying protocol to support UDP data transfer, with Forwards Error Correction (for both Unicast and Multicast). What is more, NDI now automatically detects NICs, and all the possible paths between a source and a destination, in order to spread the bandwidth out across all possible paths. This delivers much better performance in almost every case, even on high latency networks. What is more, very sophisticated internal congestion control reduces packet loss, and helps everything run on real-world networks which often employ ‘less than ideal’ routers or switches.

More reliable discovery

Numerous discovery and connection edge cases are handled better, to provide increased reliability when network topologies change, across multiple NICs (or networks) and much more. In other enhancements, NDI discovery on the local machine is improved as also are NDI sources on virtual networks.

NDI Hardware

NewTek will soon be launching a reference FPGA project running on a Xilinx reference board that we will let people play with for free; if you make a commercial project then we should talk about how we can work together to make it successful.

And more …

Traditionally, using RGB video was 80% slower than YCbCr. We’ve added AVX2 optimizations to bring this down to just 20% (assuming you have enough memory bandwidth on your system to keep up). We also now support 4:2:0 video color spaces on input, and we even include FFMPEG for Windows with NDI support for your convenience, eliminating the hassle of working out how to compile it yourself.

You Want it When?

O lançamento está previsto para logo após o NAB (quando tivermos acordado da diversão. Vemos você lá!)
