Abstract
This invention provides a matrix switcher apparatus adapted to arbitrarily distribute signals in a plurality of input channels to a plurality of output channels. The matrix switcher apparatus includes a cross point matrix adapted for connecting one matrix switcher unit to any other matrix switcher unit or units to carry out expansion of input/output, and input and output terminals expandable up to a predetermined maximum number of channels. Further, this invention provides a matrix switcher apparatus comprising a first cross point matrix including a first group of input terminals to receive signals in a plurality of channels, and a first group of output terminals for at least some of the plurality of channels and a second group of output terminals for expansion to any other unit or units; and a second cross point matrix including a second group of input terminals coupled with the first group of output terminals and a third group of input terminals for receiving signals from one or more additional matrix switcher apparatus for expansion, and a third group of output terminals fewer in number than the plurality of channels, thereby making it possible to construct a matrix switching system on a compact scale or in any of a variety of scales, and to reduce its cost.
