Ancillary Data Specifications
A multichannel encoder equipped with a FLE X-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.
Table 7–10 describes the ancillary data specifications supported by the FLEX-1 Module.
Input Specifications
Table 7–11 describes the input specifications of the FLEX-1 Module via one of the optional
inputs (IP, ASI, or RF). Refer to the chapter for each input type to see its specifications.
