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…
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. …
The systems layer described in ST 2110-10 is the foundation on which everything else depends – precision timing via PTP, stream discovery with SDP, and forward error correction. This chapter explains how these protocols work together to synchronize separated elementary streams, and all with microsecond accuracy. …
ST 2110 replaces SDI cabling with IP networking and splits video, audio and ancillary data into separate synchronized streams for live broadcast production. In this guide we explore the standard’s architecture, explain how its many parts fit together, and show why it depends on contributions from organizations far b…
Metadata is the invisible infrastructure that makes your content searchable, manageable and monetizable. Yet it’s routinely neglected until far too late in the production cycle. We examine what metadata really is, why it matters at every stage of the content lifecycle, and how poor metadata design can l…
Open-source, royalty-free and endlessly extensible, Matroška has become the container of choice for modern video distribution and the foundation for formats like WebM. This guide explains its nested element structure, maps the IANA registries that govern it, and shows why MKV keeps gaining ground. …
Thirty years on, Apple’s AIFF format remains a reliable workhorse for uncompressed audio production and archiving. We explore its chunk-based structure, clarify the differences between AIFF and AIFF-C, and demonstrate why this ancient format refuses to fade away. …
AES31 may not be starring in any headlines, but its Broadcast Wave Format remains a workhorse for professional audio exchange. Here we chart the development of the four-part AES31 standard, and prove why BWF still matters in modern workflows. …
