VBI FIFO and Ancillary Data in Video Stream
Sliced VBI data can be output as ancillary data in the video stream in ITU
–
R BT.656 mode. VBI data is output on the
Y[9:2] terminals during the horizontal blanking period following the line from which the data was retrieved. Table 2
–
7
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 the FIFO is 512 bytes. Therefore, the FIFO can store up to 11 lines
of teletext data with the NTSC NABTS standard.
