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
, and
Chapter 9, ATSC RF Input Module
for descriptions and cabling
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
Chapter 3, Operating the Encoder
Cabling the FLEX-1 Module
This section describes how to cable the FLEX-1 Module. It provides examples for the
following systems:
