GS9090 Data Sheet
28201 - 1
July 2005
32 of 70
If any DID or SDID value is set to zero in the ANC_TYPE register, no comparison
or match will be made for that value. For example, if the DID is programmed but
the SDID is set to zero, the device will detect all ancillary data types matching the
DID value, regardless of the SDID. If both DID and SDID values are non-zero, then
the received ancillary data type must match both the DID and SDID cases before
the device will assert ANC_DETECT HIGH.
In the case where all five DID and SDID values are set to zero, the GS9090 will
detect all ancillary data types. This is the default setting after a device reset.
Where one or more, but less than five, DID and/or SDID values have been
programmed, then only those matching ancillary data types will be detected and
indicated.
NOTE: See SMPTE 291M for a definition of ancillary data terms.
