Error Analysis

BIP-2
(Bit-Interleave Parity - 2 bits): The BIP-2 error indicates a parity
error by performing a routine even-parity check over all VT1.5 bytes of
the previous frame of a composite signal (VT1.5/VT2/VT6).
³
REI-V
(Remote Error Indicator): The REI-V error is declared when bit 3
of the V5 byte is set to “1”.
