The Human Infrastructure: How Netflix Built the Operations Layer Behind Live at Scale

Netflix has scaled from one monthly show in 2023 to over 70 events monthly by 2026.

• •The Broadcast Operations Center (BOC) processes signals from venues, handling conditioning, closed-captioning, graphics insertion, and redundant switching.
• •Transmission specifications require three discrete transmission paths, full hardware redundancy, dual power sources with UPS, and exhaustive pre-show testing.
• •The operational model evolved through four phases: all-hands engineering, specialized SOE/BOE teams, co-pilot control rooms, and the Transmission Operations Center (TOC) fleet model.
• •The TOC model optimizes efficiency by separating broadcast and streaming functions, with TCOs managing up to five concurrent events.
