RM-HD(E)1 Block Diagram
These expansion boards allow the
monitoring of embedded audio channels
within an SD/HD-SDI video signal. The
embedded audio can be either non-
encoded linear PCM (RM-HD1), Dolby® E
or Dolby® Digital (RM-HDE1) depending
on which card is used.
The RM-HDE1 card is for use with the
RM-4C8 whilst the RM-HD1 card can
be used with the RM-2S4, RM-2S10
and RM-4C8.
The expansion board can extract two
AES/EBU groups (4 stereo pairs) from the
video signal and pass them to the main
Reference Monitor unit for monitoring.
The input is autosensing for either SD or
HD input formats and the extraction of
embedded audio complies with SMPTE-272
(SD) and SMPTE-299 (HD).
The SDI input is equalized, internally
reclocked and re-transmitted to
provide a reclocked output to pass to
external equipment such as another
reference monitor.
