Solving Lip Sync Issues for Remotely Produced Multi-language Sports Events Over IP at Minimal Cost Whitepaper
In the past few years, live broadcasting specifically live sports has fostered the growth of remote broadcasting. Though applications vary, remote broadcasting essentially relies on the use of IP connectivity to reduce production costs in a variety of ways. This includes not having to send staff on location, potentially a huge saving.
Help is at hand. Grass Valley's Media Assurance Technology makes the necessary adjustments to the video and audio signals automatically and continuously to millisecond accuracy. This means that a highly complex problem requiring very tricky continuous adjustment can be managed without human intervention, saving on equipment costs and delivering a higher quality of service without lip sync errors.

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.

Centralized Multistation Operation with iTX Whitepaper
About ten years ago, following the widespread deployment of master control automation systems in the US station market, the concept of centralized operation of multiple stations under common ownership was evaluated and, in several cases, deployed. The results of these initial multistation centralizations were mixed, and a primary objective of significantly lower operating costs was not always achieved since the resultant savings in manpower proved inadequate to offset the cost of the required communications links at 1990s' rates. Nevertheless, several of these centralized projects continue in operation today, and a few have been expanded or upgraded with newer technology. Overall, however, the anticipated substantial benefits of station group centralization have not been fully realized, and broadcasters continue to look for new models to improve their bottom line through reduced costs.

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.

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.
