Software and IP technologies have revolutionized live event broadcasting over the past decade. However, evolving media consumption habits have outstripped the capabilities of traditional hardware-centric broadcast infrastructures. Broadcasters face increased market fragmentation and pressure to produce more content with fewer resources. IT and cloud computing innovations offer promising solutions but transitioning from hardware to IT-based architectures poses challenges. Unlike broadcast's clock-driven real-time synchronization, IT equipment operates asynchronously, necessitating a shift in how live video is managed. This paper explores a new paradigm in software-based broadcast infrastructure, capable of bridging broadcast and IT domains while meeting high broadcast standards. It will cover: Synchronous vs. asynchronous operations System architecture, including framework design, media microservices, timing, and application control Empirical data showing time savings from asynchronous processing Benefits for live production, such as scalability, reliability, agility, and composability
