Using the cards with the SDI-TD-MUX-4 and SDI-TD-
DMUX-4
The SDI-TD-MUX-4 can be used to multiplex 4 SD-SDI signals into a single HD-SDI. This
HD-SDI signal can in turn be used as input to the HD-TD-3GMX-2 or the SDI-TD-3GMX-5.
This means that is possible to embed up to eight SD-SDI signals on one 3G transport signal
with the use of either two SDI-TD-MUX4 + one HD-TD-3GMX-2 or one SDI-TD-MUX-4 +
one SDI-TD-3GMX-5. In addition, one SDI-TD-MUX4 + one HD-TD-3GMX-2 can effectively
be used together as one SDI-TD-3GMX-5, but at a slight penalty in the power consumption
and by using two rack slots instead of one.
The de-multiplexer side should normally be a mirror of the multiplexer setup. Although the
SDI-TD-DMUX-4 (and indeed the SDI-TD-MUX-4) has built-in matrices for routing
(‘shuffling’) the four SD-SDIs, it’s not possible to do any routing on the HD-SDI level.
