3.10.2.1 Programmable Ancillary Data Detection
Although the GS1560A will detect all types of ancillary data
by default, it also allows the host interface to specifically
program up to five different ancillary data types for
detection. This is accomplished via the ANC_TYPE register
(Table 5).
For each data type to be detected, the host interface must
program the DID and/or SDID of the ancillary data type of
interest. The GS1560A will compare the received DID
and/or SDID with the programmed values and assert YANC
and CANC only if an exact match is found.
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.
In the case where all five DID and SDID values are set to
zero, the GS1560A will detect all ancillary data types. This
is the default setting after 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 1: The GS1560A will always detect EDH ancillary
data packets for EDH error detection purposes, regardless
of which DID/SDID values have been programmed for
ancillary data indication, (see Section 3.10.5.2).
NOTE 2: See SMPTE 291M for a definition of ancillary data
terms.
