Data Bytes
The VBI_WORD_4 to VBI_WORD_N+3 contains the data-
words that were decoded by the VDP in the transmission order.
The position of bits in bytes is in the inverse transmission order.
For example, closed caption has two user data bytes as shown in
Table 76. The data bytes in the ancillary data stream would be as
follows:
Rev. 0 | Page 55 of 112
VBI_WORD_4 = BYTE1 [7:0]
VBI_WORD_5 = BYTE2 [7:0]
The number of VBI_WORDS for each VBI data standard and
the total number of UDWs in the ancillary data stream is shown
in Table 72.
