The good news about InfiniteReality DGs beside his higher bandwidth and number
of channels (8) is that THERE IS NOT A FIXED LIST OF MCO FORMATS. Also the base
configuration has TWO video channels without any additional hardware.
Unlike with MCO in RE2, the user can make his own format combinations using a
graphics tool in which you design the layout and combinations that you need.
In this tool called ircombine you can control:
a) Video Output format per each channel (from a list of formats)
b) Framebuffer location of each channel (the channels can overlap)
c) The static resolution scaling per channel (i.e. you can render 314x1003 and
zoomout to 1280x1024 video format)
d) Encoder location for the composite and Y-C output.
e) Location of the Sirius video out.
At the same time the tool will give you information about the framebuffer to DG
bandwidth, as well as if you are over the limits of the machine.
At the end you SAVE the format as my_cool_mco_vof.cmb.
You can push a button call download and it will change it ON THE FLY (only if
the X managed area is equal or smaller).
There is a list of DG formats but you can combine it at you convenience.
This list of formats is even larger than in RE2 for a single channel since now
the DAC bw is very large for some channels.
In a second software release this year we are going to ship even a video
compiler to let you program even your own list of vof choices (only for video
experts) but for "MCO" there is no list, you build your own.
... and with no additional cost or delays.
If you have a machine with 6.2 you can download the ircombine online books if
you wish more details, even if you did't buy yet an IR :-)
