Path Finding Between Analog and Digital Equipment
Automatically Converting Separate Analog Signals to Combined Digital
Signals
The Path Finding table can be used with customer-supplied Analog to
Digital Converters (ADCs) and Digital to Analog Converters (DACs) to
provide automatic conversion between analog equipment and digital
equipment (such as VTRs). See Figure145.
Figure 145. Example of ADC and DAC
For example, this technique can be used for conversion of analog audio sig-
nals, which are carried on two levels of an
analog routing switcher, to a
single digital audio (AES) signal. The same concept can be applied in an
embedded audio environment, where a single digital video stream can be
split into an analog video signal and up to four analog audio signals.
It is possible to arrange a system so that
the conversion will take place
whenever the operator selects a particular source and switches it to a par-
ticular destination. For example
, in the system shown in Figure146, when-
ever the operator selects VTR1 as the source for VTR2, the analog audio
s
ignals will always pass through an A to D converter; when VTR2 is the
source for VTR1, the digital signal will pass through a D to A converter.
