VBI FIFO and Ancillary Data in Video Stream
Sliced VBI data can be output as ancillary data in the video stream in the ITU-R BT.656 mode. VBI data is
output during the horizontal blanking period following the line from which the data was retrieved. Table 3-2
shows the header format and sequence of the ancillary data inserted into the video stream. This format is
also used to store any VBI data into the FIFO. The size of FIFO is 512 bytes. Therefore, the FIFO can
store up to 11 lines of teletext data with the NTSC NABTS standard.

DID:
91h: Sliced data of VBI lines of first field
53h: Sliced data of line 24 to end of first field
55h: Sliced data of VBI lines of second field
97h: Sliced data of line 24 to end of second field
SDID:
This field holds the data format taken from the line mode register of the corresponding line.
NN:
Number of Dwords beginning with byte 8 through 4(N+2). This value is the number of Dwords where each Dword is 4
bytes.
IDID0:
Transaction video line number [7:0]
IDID1:
Bit 0/1 = Transaction video line number [9:8]
Bit 2 = Match 2 flag
Bit 3 = Match 1 flag
Bit 4 = 1 if an error was detected in the EDC block. 0 if not.
CS:
Sum of D0–D7 of DID through last data byte
Fill byte:
Fill bytes make a multiple of four bytes from byte 0 to last fill byte. For teletext modes, byte 8 is the sync pattern byte.
Byte 9 is 1. Data (the first data byte).
