Ancillary Data Specifications
A multichannel encoder equipped with a FLEX-1 Module is receiving and outputting
compressed streams. The FLEX-1 Module does not re-create any of the ancillary data (also
referred to as VBI data), it simply passes it intact as packets of bits, to the encoder’s TS
output.
NOTE:
The terminology used regarding ancillary data can be incorrect or misleading. VBI data is not
applicable to fully digital signals, but is used by user habit.
