Overview
This practical hands on course provides a comprehensive introduction to SMPTE ST 2110 and its role in modern IP based media systems.
The course covers uncompressed video, Audio-over-IP, and ancillary data as separate essences, with comparisons to compressed workflows via ST 2110-22.
Participants will explore key standards including ST 2110-10 to -60, PTP-based timing and synchronisation, QoS, multicast delivery, and AMWA NMOS (IS-04 to IS-10) with recommended practices.
Each module is reinforced with hands-on labs involving packet analysis, stream inspection, and protocol troubleshooting.
Prerequisites
