What is Over-the-Top Video?
Over-the-top video delivers programming through the public internet. It does not require a traditional cable, satellite, or operator-managed television distribution network.
How Over-the-Top Video works
OTT video reaches viewers over ordinary IP connectivity through applications and web players rather than through a dedicated television distribution path. Services typically combine catalog or schedule systems, encoding, adaptive packaging, rights enforcement, telemetry, and CDN delivery. Live channels, events, rentals, and subscription libraries can all use this route, so OTT describes distribution rather than a single business model or protocol. Playback quality varies with access networks and device capabilities, making rendition selection and resilient clients central to the workflow.
Key facts
- 1OTT playback commonly uses HTTP-based segmented media so a player can change rendition at segment boundaries as measured bandwidth and buffer health change.
- 2DRM systems, codecs, containers, caption formats, and advertising APIs vary across televisions, browsers, and mobile platforms, forcing device-specific testing.
- 3Glass-to-glass latency includes capture, encoding, packaging, CDN, download, and player buffering; optimizing only one stage may not materially reduce it.
When Over-the-Top Video matters
Choose OTT delivery for subscription catalogs, ad-supported channels, or direct-to-consumer live events. Internet variability requires adaptive playback and cannot provide the controlled conditions of a managed network.
