Virtual mapping function
This function lays out routing switcher crosspoints on a virtual matrix of 1024 inputs x 1024 outputs
when eight levels are used or 1024 inputs x 512 outputs when 16 levels are used.
The virtual mapping capability of Sony routing switchers features two types of mapping:
(1) A single routing switcher can be mapped to operate as a number of individual routing
switchers. For example, a single 256 x 256 multi bit rate routing switcher can be divided
into, say, a 192 x 192 switcher and a 64 x 64 switcher so that the corresponding crosspoints
on these two levels are switched simultaneously. This
allows a 192 x 192 HD switcher and a
64 x 64 SD switcher to be created (Figure-5).
(2) Multiple routing switchers can be mapped on a larger, virtual routing level (Figure-6). This
application could be used in the tie-line management system described above in section 5.
Self-diagnostic function
This function can send information on errors and the presence/absence of inputs to a control
terminal connected to the primary station for display.
