Structure of VBI Words in the Ancillary Data Stream
Each VBI data standard has been split into a clock-run-in
(CRI), a framing code (FC), and a number of data bytes (n).
The data packet in the ancillary stream includes only the FC
and data bytes. Table 76 shows the format of VBI_WORD_x in
the ancillary data stream.

VDP Framing Code
The length of the actual framing code depends on the VBI data
standard. For uniformity, the length of the framing code reported
in the ancillary data stream is always 24 bits. For standards with
a smaller framing code length, the extra LSB bits are set to 0.
The valid length of the framing code can be decoded from the
VBI_DATA_STD bits available in ID0 (UDW 1). The framing
code is always reported in the inverse-transmission order.
Table 77 shows the framing code and its valid length for VBI
data standards supported by VDP.
Example
For teletext (B-WST), the framing code byte is 11100100 (0xE4),
with bits shown in the order of transmission. VBI_WORD_1 =
0x27, VBI_WORD_2 = 0x00, and VBI_WORD_3 = 0x00
translated into UDWs in the ancillary data stream for nibble
mode are as follows:
UDW5[5:2] = 0010
UDW6[5:2] = 0111
UDW7[5:2] = 0000 (undefined bits set to 0)
UDW8[5:2] = 0000 (undefined bits set to 0)
UDW9[5:2] = 0000 (undefined bits set to 0)
UDW10[5:2] = 0000 (undefined bits set to 0)
For byte mode,
UDW5[9:2] = 0010_0111
UDW6[9:2] = 0000_0000 (undefined bits set to 0)
UDW7[9:2] = 0000_0000 (undefined bits set to 0)
