ATSC RF Input Module
The RF Input Module is a four-channel ATSC 8VSB receiver. It receives four independent
ATSC 8VSB signals on the inputs and outputs four MPEG-2 Transport Streams over the
chassis internal bus to one or more FLEX decoding modules. The RF Input module does not
support analog demodulation.
The RF Input Module can be managed by NMX.
NOTE:
The four inputs are enabled by optional firmware licenses.
