Playout

Playout is the process of delivering scheduled television or radio content to an audience. In broadcasting, it refers to the output stage that transmits programs, commercials, and promos to distribution networks, stations, or streaming platforms. Playout systems automate the chain from asset management to transmission, enabling operators to execute a predefined playlist with precise timing.

Key components include a media asset management system for locating and organizing content, an automation engine to read and execute a playlist, broadcast servers that fetch and play media, and facilities for graphics, captions, and branding. The workflow typically involves ingesting and cataloging assets, creating a rundown or playlist, and then timing and switching between items so continuity and ad insertion are maintained. The system may also handle regional inserts and monitoring of signal quality.

Many broadcasters operate traditional linear channels, and playout can be on-premises, but cloud-based playout services are increasingly common, enabling scalable, multi-channel operations and remote management. Cloud playout uses virtualization and software-defined video appliances to deliver content to satellite, cable, or streaming endpoints via networks and content delivery networks (CDNs).

Playout is distinct from production, which creates and edits content. It is closely associated with master control room operations, which monitor and manage the broadcast feed. The concept also applies to non-broadcast contexts such as corporate channels and over-the-top services delivering linear streams.
