Background
As the broadcast industry evolves from Serial Digital Interface (SDI) to IP, it’s reasonable to expect certain challenges. IP networks are flexible and powerful but can suffer from a range of performance issues such as jitter and packet loss, which adversely affect video transmission. For instance, for an ST 2110 deployment, how can you be certain that at the receiving end, the network stream will have the exact packet order and pace as at the transmitting end? In most cases it won’t have. This doesn’t mean that networks are not reliable; it just means that they need to be well designed and tested to ensure they are standards-compliant and working as expected.

This document provides a brief overview of the SMPTE (Society of Motion Picture and Television Engineers) standards for broadcast over IP networks. It also details the various impairments that can be used when testing for ST 2110-21, and proposes a test procedure to ensure the network system meets ST 2110-21 standards.
