Introduction
The Harmonic FLEX-1 decoder module performs video and audio decoding of compressed
input and output decoded elementary streams directly to the encoder audio/video
processing cards. A single FLEX-1 Module is able to decode up to two incoming channels,
and an appropriately configured encoder can support up to two FLEX-1 Modules delivering
up to four channels in a single rack-unit (1-RU).
The FLEX-1 Module decodes MPEG-2 or AVC in both standard definition (SD) or high
definition (HD) formats, thereby eliminating the dependency on ingress formats. The FLEX-1
Module is a unique gateway designed with the flexibility to deliver any type of pre-
compressed video to any host encoder.
NOTE: AHC-561 card is not supported for use with FLEX-1 Modules.
The FLEX-1 Module decodes compressed streams delivered over IP, ASI, or RF (8VSB) input
from optional modules installed in the encoder chassis. See section
Cables, Chapter 8, ASI
instructions for these input options.
NOTE: The FLEX-1 Module does not descramble or reconstruct all audio and ancillary data services
(such as VBI).
You configure the FLEX-1 Module and the services it provisions using the NMX Digital
Service Manager application, as described in
