Ross Video has release the QSP-8229 quad split video processor, which supports four video inputs combined into a single quad split output with configurable quadrant labeling and bordering with transparency.
The four 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.
The QSP-8229 also offers passive looping inputs, allowing it to fit into any video path without the need for additional distribution amplifiers, thus reducing system complexity. Looping is performed on the back module ensuring the signal path is not lost even if the processor is removed.
