Abstract:
An apparatus for receiving a first stream of data signals at a first input and for receiving a second stream of data signals at a second input, the apparatus comprising:(a) a first switch connected to the first input and having a first switch output, the first switch for passing the first stream of data signals from the first input to the first switch output in response to a first switch enable signal applied to an enable input associated with the first switch; (b) a second switch connected to the second input and having a second switch output, the second switch for passing the second stream of data signals from the second input to the second switch output in response to a second switch enable signal applied to an enable input associated with the second switch; (c) a controller for selectively applying the first switch enable signal and for selectively applying the second switch enable signal; and (d) a memory device connected to the controller, the memory device storing signal path information for a plurality of channel outputs, the signal path information for each respective one of the channel outputs relating the respective channel output to one of the first switch or second switch which must be enabled to pass data signals from which the respective channel output can be produced.
