Traditional linear broadcasting is evolving into on-demand streaming, but DVB standards still underpin terrestrial, satellite and cable transmission worldwide.
Elementary streams carrying audio, video and metadata are combined into program streams, which are then multiplexed together into transport streams for broadcast. Here’s how it all works as well as what you need to plan for.
Delivery specifications define how production studios should package and submit finished programs and can cover everything from video codecs, audio stems and metadata manifests to epilepsy testing and file-naming conventions. Here we uncover some of the key themes and explain how building a superset of assets from the outset can save money.
Developed by AMWA as an open standard, NMOS provides the discovery, registration and connection management that ST 2110 lacks on its own. This comprehensive overview identifies exactly what NMOS is, why it is important and how it should be applied.
Timed text carries far more than just subtitles; it enables accessibility, triggers interactive events, and synchronizes captions across broadcast and web platforms. There are several standards to navigate, and each has different conversion challenges to navigate.
Metadata affects the entire lifecycle of media assets and describes many properties which are all important at different times during the media lifecycle. Sufficient detail is necessary to manage visual effects in post production and workflow processing and the rabbit hole is very deep. We find out how deep it goes.
The ST 2110-3x suite of standards are all about audio. Here we explain how it handles multi-channel PCM audio, why conformance levels matter for channel capacity, and what the AES has got to do with it all.
The ST 2110-2x standards govern how video flows through IP broadcast networks and the traffic shaping that prevents network congestion. This guide explains how these parts work together to move video with minimal latency.
