PBIN
PRBS before interleaver.
Pure pseudo-random bit sequence (PRBS) data used as modu-
lation data with no packet structure. PRBS data conforms with
ITU-T O.151 specification.
PBET
PRBS before trellis.
Pure pseudo-random bit sequence (PRBS) data used as modu-
lation data with no packet structure and interleaving. Modulation
data is directly fed to the trellis encoder.
PBEM
PRBS before mapper
Pure pseudo-random bit sequence (PRBS) data directly fed to
the mapper.
Three bits at a time in two's complement are assigned to the
stages -7, -5, -3, -1, 1, 3, 5, 7. Subsequent pilot insertion and
VSB filtering remain unaffected.
