5.15.3 Special features
•
If more than one of the stores is set to transmit in the same space (HANC or VANC) of
the same line, the packets will be transmitted in ascending order of store number.
•
More than one store can be set to pass the same type of packet. The lowest
numbered empty store is used. Different input fields and output line numbers can be
used.
•
The line number on which an input packet occurs and whether it was in HANC or
VANC is reported each store. These registers are cleared after they are read so
subsequent reads will say 0 - valid line numbers are from 1. This is how to tell whether
the nominated ANC packets are occurring or not (a valid output line number must be
set since new packets aren't reported whilst a store is full).
•
If the DID for a store is set to 128 or greater, the SDID register is ignored and all
packets with that DID can be passed through that store. (These packets are type 1
and the place of the SDID is taken by a data block number.)
•
A range of up to 32 SDIDs can be matched for a given DID by setting the SDID range
bits for a store.
To pass a single SDID, set the range to 0.
For Dolby metadata (SMPTE 2020-1) the SDIDs can be from 1 to 9 so the SDID
would be 1 and the range 8.
