Open standards and direct IP conversion

On this platform, Dan Maloney, head of technical marketing at Matrox Video, reflects on the possibilities that IP brings to the world of live events and highlights the importance of conversion in the current technological context.

In the world of live event production, video technology is evolving quickly, turning significantly towards the based workflows IP. The driving force behind this transition is the need to benefit in more ways flexible, scalable and efficient of moving video signals across different types of equipment and networks.

Open standards and conversion to IP have become fundamental elements to face the challenges posed by this diversity of formats and protocols video at live events. While open standards enable vital interoperability and simplify workflows, IP conversion technologies open up new possibilities to achieve more creative and efficient productions.

The challenge of production islands

Live event production has long been limited by production islands– The disparate systems and protocols that coexist in a production environment. Some video equipment depends on SDI, while others use NDI, SMPTE ST 2110 or other protocols. Although each of these formats has its advantages, the lack of interoperability between systems and protocols can create bottlenecks in the same production workflow.

Although each format It has its advantages, lack of interoperability between systems and protocols can create bottlenecks in the same production workflow.

In a typical live event, whether a concert, sports coverage or corporate presentation, the path that video signals travel from cameras to monitors, switchers and, ultimately, to large screens or projectors, involves the signal conversion between different formats (this is even more evident when both local and remote production tools coexist). Without a way to unite the different formats, the production team is forced to scramble to ensure that all devices can communicate effectively.

IP conversion: the door to interoperability

IP conversion technologies solve this interoperability problem by serving as catwalk between the different video formats; facilitate a fluid communication and allow multiple systems to work well together within a broader workflow.

IP converters translate IP video outputs still common standard which can be routed through the production system.

A typical use case for IP conversion in live events is video signal transport from the cameras to production teams. IP cameras can be installed in a venue to capture the action, with video output in formats such as NDI, RTSP or ST 2110 or JPEG XS. These signs must process and displayed on large monitors or screens, or recorded for post-production, and IP converters make this possible translating IP video outputs still common standard which can be routed through the production system.

IP conversion is also extended beyond local workflows, as it supports productions that involve multiple locations or that broadcast content outside the event location. In these cases, in which it depends on a WAN or of Internet, IP conversion tools allow the H.264/5 video delivery within an SRT stream, allowing live event managers to maintain high-quality video while minimizing latency during transmission.

The importance of open standards

Although the patented solutions can solve specific workflow problems and reduce interoperability problems, often creating silos what limit the capacity of the different systems to work together. By providing a common language For communication between devices and video systems, regardless of manufacturer, open standards such as SMPTE 2110 e IPMX offer a more approach flexible and prepared for him future.

In addition to promoting interoperability, open standards ensure that those responsible for live events have the flexibility to choose the best tools for their needs without being trapped in a single ecosystem. As a result, production teams maintain the agility needed to adapt to diverse production environments, whether working with IP-based cameras, fiber-based transport systems, or even Internet video distribution. Furthermore, the ability to route and discover video signals using open standards Simplifies integration, making it easier for technical teams to set up and manage complex workflows.

Latency, quality, and workflow considerations

The specific needs of a live production will dictate what aspects of an IP conversion system They are more important. For many productions, the latency is a critical factor, especially when it comes to live video that must be synchronized with the action in real time. In these cases, the use of uncompressed video over IP, such as SMPTE ST 2110, ensures that latency and quality are not compromised. However, in situations where the bandwidth is limited, los productores de eventos en directo pueden optar por formatos de vídeo comprimido, como JPEG XS, que ofrecen una calidad visual sin pérdidas con una latencia mínima. Este enfoque es especialmente útil para producciones que necesitan transmitir vídeo a través de redes gigabit en lugar de conexiones de fibra de mayor ancho de banda.

To entornos de red más estándar, protocolos como NDI y SRT They offer a good balance between latency, quality and bandwidth requirements. Although these formats may involve some trade-offs in latency or pixel-perfect quality, they are ideal for delivering high-quality video over existing network infrastructure without the need for costly upgrades. Whatever the situation, the solid doors of IP video link, such as converter and encoder/decoder families Matrox ConvertIP o Vion, can admit various applications, formats, codecs and types of network while balancing quality, latency and bit rate needs, serving as a versatile tool to create and optimize live production workflows.

Libertad creativa para los productores de eventos

Una de las ventajas más interesantes de adoptar flujos de trabajo basados en IP y estándares abiertos en los eventos en directo es la creative freedom que pueden conseguir los equipos de producción. Al eliminar las preocupaciones sobre la infraestructura subyacente, los productores de eventos pueden centrarse en lo más importante: ofrecer una experiencia excepcional a su público. Ya se trate de retransmitir en directo un acontecimiento deportivo, retransmitir un concierto o producir una presentación corporativa, pueden utilizar la tecnología de conversión IP para integrar las mejores herramientas para el trabajo.

Given the growing number of professionals who are experts in IP networks and infrastructure, it is becoming easier every day for live event teams to manage these complex systems. With the adequate support, event producers can use video in new and innovative ways.

Looking to the future: tomorrow of the IP in live broadcasts

The technologies of IP conversion and the estándares abiertos are transforming the production of live events by allowing interoperability, improve the flexibility and offer new creative opportunities. The flexibility and scalability offered by IP-based systems make them an ideal solution for a sector that requires adaptability and innovation.

Given the growing number of professionals experts in IP networks and infrastructure, every day it is easier for the teams of live events manage these certainly complex systems.

As the use of IP in live video production continues to grow, open standards and conversion to IP will play a role. increasingly essential role; not only to enable interoperable workflows at live events, but also to ensure that these networks can support the growing demand for high-quality, low-latency video.

So, in the future, live event producers will have more tools at their disposal to create attractive and dynamic productions that captivate the public, whether in situ or at a distance.
