Ross Video (http://www.rossvideo.com) has released the QSP-8229, a
quad split video processor.

The QSP-8229 monitors up to four video inputs combined into a single
quad split output with configurable quadrant labeling and bordering
with transparency. The four configurable outputs can be assigned to
be a quad output or a pass through of the input, with a full video
proc, offering additional outputs for use elsewhere in a system.

Eric Goodmurphy, RossGear product marketing manager, says that unique
to the QSP-8229 is the passive looping inputs, allowing it to fit
into any video path without the need for additional DA's reducing
system complexity. Looping is performed on the back module ensuring
the signal path is not lost even if the processor is removed.
