La prochaine étape pour NDI®

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

Depuis ses débuts, NewTek a pour mission de permettre à ses clients de proposer un storytelling de qualité grâce à la vidéo. Nous sommes certains que la prochaine génération d'outils vidéo reposera sur trois piliers essentiels : les ordinateurs, les logiciels et les réseaux. De plus, ces outils ne seront pas réservés aux clients les plus fortunés, mais disponibles pour toute personne souhaitant produire un événement ou encore streamer les activités de son équipe, de son école ou de son association tout en s'amusant.

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

Cette petite application est capable de grandes choses. Les panneaux d'affichage font partie intégrante du secteur de la vidéo, c'est pourquoi nous avons créé Studio Monitor pour prendre en charge cet aspect. De nos jours, pratiquement chaque diffusion intègre plusieurs écrans : façades de bâtiments, réceptions ou encore affichage sur écrans géants. Pour autant, transmettre ces sources à l'aide de câbles analogues s'avère peu pratique, le matériel SDI est extrêmement onéreux et la technologie HDMI n'est pas une solution viable en raison de ses limites en matière de distances. La réponse : l'IP, bien entendu ! C'est une technologie fiable, peu coûteuse et universelle.

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!

Autre ajout significatif à Studio Monitor, vous pouvez incruster des titres et des contenus graphiques (y compris des animations vidéo intégrales) à l'écran. Attribuez un overlay qui s'affichera dans la vidéo de votre hall d'entrée et optez pour un overlay différent pour votre salle d'exposition. Vous pouvez aussi utiliser la fonction Overlay pour créer une sortie picture-in-picture. Chaque instance Studio Monitor peut désormais choisir quel dispositif audio utiliser pour la lecture, et sur quel(s) moniteur(s) vidéo la sortie devrait s'afficher. Vous pouvez même configurer Studio Monitor afin qu'il s'exécute au démarrage d'un ordinateur. De cette manière, plusieurs instances, toutes correctement configurées, se lanceront automatiquement. Achetez un NUC ou deux afin de créer plusieurs sorties 4K, contrôlables à distance.

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

NDI Virtual Input

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

Cette nouvelle version prend désormais en charge VLC 3.0 et VLC 2.x. La commande PTZ virtuelle est intégrée, vous permettant ainsi d'effectuer un panoramique et de zoomer dans la sortie VLC affichée dans Studio Monitor, comme si vous contrôliez une véritable caméra PTZ. La prise en charge de formats vidéo est améliorée (horodatages, et plus encore).

Adobe CC drivers

Le nouveau pilote prend en charge la toute dernière version d'Adobe CC. Il offre également une plus haute qualité, prend en charge les couleurs à virgule flottante, et plus encore.

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

Tout le kit SDK est désormais plus facile à utiliser. Les fonctions sont plus simples à comprendre, mais restent entièrement disponibles pour une compatibilité descendante. Pour les nouveaux utilisateurs de l'écosystème NDI, le nouveau guide de démarrage du SDK permettra d'apprendre à utiliser le SDK plus rapidement.

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?

La sortie est prévue dès la fin du NAB (soit dès la fin des festivités. Rendez-vous au salon !)
