AFD Insertion (AFD Module)
The AFD module encodes and recovers Active Format Descriptors (SMPTE 2016-1-2007). The feature 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 module provides low-latency dynamic switching between AFD sources, with configurable priority
between upstream encoded data, presets, and a simple network automation protocol. An AFD input/output
switching matrix allows users to pick desired input sources and produce a single consistent AFD packet for each
field of the output signal. Additionally, users have the ability to set code swap rules that enable dynamic mapping
from one AFD code at the input to another at the output
To determine if the AFD feature is installed on your unit, access your encoder’s web interface, look for an entry
that says AFD on the left side menu and select it. If you are prompted for a license key, the feature is not installed
and can be purchased by contacting the EEG sales team.
This feature is ideal for complex broadcast environments requiring continuous AFD data on programming,
commercials and interstitials, and more. The switching and data continuity features provide frame-by-frame AFD
service confidence.
