Ancillary Data Flow
For each TV line, the following sequence is generated immediately after the EAV code:
DID & SDID Coding Convention
All VBI data formats recognized by the Slicer use the same Data ID value. This Data ID value is
programmed in the SLDID[5:0] bits in the
is "000001" respecting an 8-bit format and coding for 8-bit applications, in compliance with SMPTE
291M specifications (the full default code is 41h when parity control bits are added). Bits 6 and 7 of
the DID value are hardware calculated (bit 6 is the even parity of bits 5 to 0, bit 7 is the binary
complement of bit 6).
All possible DID values are coded using a Type 2 ancillary data coding format.
The Secondary Data ID codes (SDID) identify the recognized data formats as follows:
