    Comparing High-Speed Camera Solutions for Live Broadcast Applications Whitepaper

    Slow-motion and super slow-motion replays have been an important part of media storytelling in nearly all live sports productions for many years. But, more and more often they are also used in other entertainment productions such as game or dance shows to deliver a new level of emotional connection to these types of studio productions.

    There are several options for the speed of the image acquisition and replay. Every option has its own strengths and limitations. What are the typical requirements for the different applications? Why are there only a very limited number of the possible scenarios that have been widely accepted?

    This whitepaper explains all these points in more detail with guidance for choosing the right technology for the application.

    Future of Production in the Age of Media Choice Vision Paper

    It is easy to regurgitate the same message about how the TV industry is going through a massive period of change. It is a theme that has been well covered and generally agreed. However, the less acknowledged fact is that the TV production world has struggled to keep pace with the intertwined drivers of technological advancement and evolving consumer behavior. Granted, there has been significant innovation, especially over the last decade with the move towards IP and software-defined systems, but the fundamental processes for many top-tier broadcasters are broadly the same as they were in the TV golden era of the 1960s and '70s.

    The Impact of New Production Formats and Workflows to Camera Control Whitepaper

    Today, camera control solutions in live broadcast productions are mainly used to adapt the camera's capabilities to a given light situation, and to achieve a certain "look" and style of the images. New formats such as high dynamic range (HDR), wide color gamut (WCG), 4K UHD, IP and simultaneous HDR/SDR or HD/4K UHD operations, require more agile controls. Now with more features to be controlled, managing the various settings becomes very difficult. A broadcast camera control solution that leverages the developments from grading applications used in post-production and other widely used image control applications, such as Photoshop, will benefit from new ideas and the new talents grown with these solutions. It's time for a change! This paper will explain the background of today's camera control solutions and show, based on extensive customer feedback, how it should develop in the future.

    Why Shaping Traffic at the Sender is Important Whitepaper

    To manage this risk in advance, broadcasters should consider how the buffers in the switch work and ensure that data senders behave in such a way that the buffers never become too full. This practice is known as sender traffic shaping. To ensure pre-compensating for this adverse effect is efficiently applied to IP, broadcasters must follow one rule: the network must be designed and managed for the desired traffic load.

    Shaping sender traffic is important for system reliability, and it is equally important to consider its impact for low latency and jitter in live production systems. To ensure the optimal workflow and performance, use the proposed SMPTE 2110-21 standard as a way to design the system, and then verify this, as well as system performance requirements, with your router vendor.

    Aggregation is Key to Optimizing IP Network Design Whitepaper

    The world of IP technology moves rapidly. The speed with which data moves through an Ethernet connection and the amount of bandwidth that connection can accommodate increases at a rate that makes network planning challenging. What makes it even more challenging? Usually, higher bandwidth interconnects, such as active optical connectors, are initially more expensive and less available due to their rapid adoption by data center and telecommunications installations. Supply eventually catches up to the demand, but costs sometimes make early adoption prohibitive.

    In the world of broadcast and media distribution, IP networks are being deployed to exploit the benefits that this technology presents: scalability; simplified geographic distribution; workflow efficiency; and the promise of future bandwidth increases. They are also being deployed in an effort to provide faster adoption of new media distribution services and formats as the role of traditional broadcast evolves into a more consumer choice-driven business model.

    Wahl zwischen Anzeigelicht und Szenenlicht basierter Umwandlung in EDIUS — Ein Beispiel für einen unkomplizierten HDR-Produktionsablauf weißespapier

    Dynamic Range (HDR) Videos für Nachrichten und Feld-Produktion einzusetzen, bei denen die unmittelbare Verbreitung des Inhaltes erforderlich ist. Ein Beispiel dafür stellt das Konzept „Instant HDR" von Sony dar, und Kameras, welche im Hybrid Log-Gamma (HLG)-Format aufnehmen können, werden auf den Markt gebracht. Wenn das Video direkt im HLG-Format aufgezeichnet wird, kann es, wenn es der Zeitfaktor erfordert, ohne jegliches Color Grading (CG) verbreitet werden.

    Ist es dann eigentlich nicht möglich, Kameras die im Log-Format aufzeichnen, wie etwa in S-Log oder V-Log, in solchen Bereichen zu verwenden? Ein Log-Signal muss nach HLG oder Perceptual Quantization (PQ) umgewandelt werden, damit es auf Consumer-TVs angezeigt werden kann — die Umwandlung selbst ist aber nicht schwer.

    Abgesehen von Liveproduktionen, können wir HDR-Clips mit nur geringer Zeitverzögerung ausspielen — nach einem schnellen Schnitt mit Cut & Paste, dem Hinzufügen von Titeln und der Formatumwandlung mit EDIUS.

    Um das zu erreichen, müssen aber einige Punkte beachtet werden: zum Beispiel unterscheidet sich die Farbgebung zwischen Log-Formaten und HLG. Wegen der Unterschiede im Quellmaterial hat die gewählte Einstellung der „Umwandlungsbasis" (Engl. Conversion Base) in der Primären Farbkorrektur Auswirkungen auf das jeweilige Ergebnis.

    ディスプレイライト基準とシーンライト基準の使い分け 即時性を重視したHDR制作フローへの応用例 Whitepaper

    映像業界では、Sonyの「インスタントHDR」など、HDR映像を 報道やライブなどの即時性が求められる用途にも活用しよう、 という取り組みが進められています。そのために、HLG(Hybrid Log-Gamma)方式で撮影できるカメラを市場に投入するなどの 動きが始まっています。

    HLGで撮影すれば、必要なら撮ったその ままの映像をカラーグレーディングなしで最終出力とすることが できるので、即時性が高まります。

    では、S-LogやV-LogなどのLog方式のカメラでは、即時性は実 現できないのでしょうか?家庭用テレビではLog方式の信号を観 ることができないので、家庭用テレビで対応されているHLGまた はPQ(Perceptual Quantization)方式に変換する必要がありま すが、変換自体は簡単に行うことができます。ライブはひとまず置 くとして、カット編集とタイトル付加程度で短時間に送出する目的 には、EDIUSで編集と方式変換を行うことが考えられます。

    その際、LogとHLGの映像トーンに対する考え方の違いなど、注 意するべき点もいくつかあります。このことは、プライマリーカラー コレクションの変換基準の選択にも関係してきます。

    Choice of Display Light and Scene Light Based Conversion in EDIUS — An Example for Instantaneous HDR Production Workflow Whitepaper

    In the video industry, efforts are made to use High Dynamic Range (HDR) video for news and live field production where immediate content distribution is necessary. One of such is Sony's "Instant HDR" concept, and cameras which can shoot in Hybrid Log-Gamma (HLG) format are to be brought into the market.

    If video is shot in HLG format directly, it can be distributed without any color grading in cases where timing is of the essence.

    Then, isn't it possible for Log format cameras like S-Log or V-Log to be used in such fields? Although a Log signal needs to be converted to HLG or Perceptual Quantization (PQ) in order to be displayed on consumer TVs, the conversion itself is not difficult. Leaving live production to one side, we can play out HDR clips with a short time lag after quick editing such as cut & paste, title addition and format conversion by using EDIUS.

    But to do so, some points need to be taken into account, for example, the concept of picture tone is different between Log formats and HLG. The "Conversion Base" setting in the Primary Color Correction has implications based on the difference of the source material.
