The broadcast industry is experiencing a rapid shift in workflow models, transitioning from traditional on-premise networks to cloud-based infrastructure, hyperscalers, and hybrid approaches. This evolution offers broadcasters a wide range of options prioritizing cost efficiency, scalability, and enhanced performance. The challenge lies in identifying the most effective solutions for specific applications.
From a technology supplier's perspective, the optimal broadcast workflow hinges on three key factors: cost effectiveness, ease of use, and a robust yet flexible environment. Transitioning to IP and hybrid workflows offers significant advantages in all three areas.
The shift from SDI to IP, and the adoption of hybrid workflows, dramatically increases flexibility and offers cost-effective solutions. Remote production is a prime example. Video over IP allows remote crews to work from home, eliminating the need for expensive physical trucks and travel, and minimizing environmental impact. Broadcasters gain greater flexibility in crew selection, fostering creativity while simultaneously reducing costs. “Broadcasters can be more selective about which graphic operator, TD or director they’d like to use because it’s not based on physical proximity to the event. So, they can increase creativity for the project while also reducing costs,” explains an industry expert.
Even within the broadcast studio, IP offers unparalleled flexibility. Workflows can be easily rearranged to accommodate new features or equipment based on project needs and crew preferences. IP connectivity future-proofs systems, eliminating concerns about cabling and simplifying format changes.
The trend towards smaller, more compact, and cost-effective video switchers continues. Modern switchers incorporating master control automation provide a robust and flexible solution for broadcasters seeking cost efficiency. A significant challenge facing the industry is the generational shift in technical directors. Younger professionals often prefer touch panels and web GUIs over large, traditional switchers. Vendors must address this by developing user-friendly, cost-effective, and creative technologies.
Software-defined infrastructure offers unparalleled flexibility, allowing operators to customize their systems and easily reconfigure them as needed. The FOR-A FA-1616 multi-channel signal processor exemplifies this approach, providing software-based features for up/down/cross conversion, color correction, HDR/SDR conversion, 1DLUT and 3DLUT, frame sync, resizing/repositioning, and video and audio processing. This software-defined approach maximizes flexibility and cost efficiency.
The development of on-premise software-defined IP platforms represents a significant advancement, offering a "station-in-a-box" approach integrating switcher, multi-viewer, processing, and audio mixing functionalities. This flexible architecture is easily adaptable to cloud operations, enabling on-premise, cloud, and hybrid deployments. "We believe a software-defined workflow will be the key for a flexible and future-proof upgrade path," says a leading developer. This platform supports easy interchangeability of manufacturer brands and future cloud-based operations.
Currently, hybrid workflows combining SDI, IP, cloud, and on-premise solutions are prevalent. Latency-sensitive operations remain on-premise, while GUI-intensive tasks are handled in the cloud. The optimal solution depends on individual customer needs. For broadcasters transitioning from SDI to IP, gateways offer a smooth transition. Ultimately, the goal is to empower customers with effective and future-proof workflows.
