Introduction
1.1
System Overview
The EEG HD490 AFD Software is a flexible and versatile module running
on the HD490 Closed Caption Encoder that encodes and recovers Active
Format Descriptors (SMPTE 2016-1-2007). The HD490 can be used to
statically insert any legal AFD code on each video field in HD VANC,
or in a privately-defined custom XDS packet in HD or SD. The software
also provides low-latency dynamic switching between AFD sources, with
configurable priority between upstream encoded data, presets, and a
simple network automation protocol. The encoder also features an AFD
input/output switching matrix which allows users to pick desired input
sources and produce a single consistent AFD packet for each field of the
output signal. Additionally, the webtools allow the user to set code swap
rules that enable dynamic mapping from one AFD code at the input to
another at the output
The HD490 AFD software is ideal for complex broadcast environments
requiring continuous AFD data on programming, commercials and in-
terstitials, and more. The switching and data continuity features pro-
vide frame-by-frame AFD service confidence, and make the HD490 a
key piece in creating an AFD-enabled 100% HD workflow.
