The SDI-TD-MUX-4 board transfers any or all of the four 270 Mbps input signals via an
optical or electrical HD interface according to SMPTE 346M-2000. An SDI-TD-DMUX-4
board is required to reconstruct the four 270 Mbps signals, normally at a remote location and
linked via an optical fiber or an electrical coax cable. The inputs to the SDI-TD-MUX-4 can be
any combination of 270 Mbps SD-SDI or DVB-ASI (188 or 204 word packets).
The output from the SDI-TD-MUX-4 module is either electrical HD according to the SMPTE
346M-2000 standard, or simultaneous electrical and optical HD according to the same
standard if an optional laser module is purchased (in which case the module will identify itself
as an SDI-TD-MUX-4-T).
