ABSTRACT:
A programmable analog N.times.M switching network that includes a charge-coupled-device (CCD) multiplexer switch means having a plurality of N input leads. The input leads contain signals from typical devices such as video cassette recorders, televisions, video cameras, cable TV telephones or the like. The CCD multiplexer switch means also includes a plurality of M output leads that provide signals to other typical devices which also may be video cassette recorders, televisions, telephones, etc. A programmable read-only memory (PROM) clock generator provides signals to CCD gates in the CCD multiplexer switch means to enable the multiplexer switch means 10 to selectively connect the input signals and leads to the output leads. The programmable PROM is controlled by means of programming request means which may be a computer or an operator console. In the operation of the system anyone of N input signals on the N input leads from N devices can be selectively modulated and connected to any one of the M output leads to M devices by means of an analog multiplexer circuit under the control of clock signals from a PROM device which are selected by a programming request means.
