2.10.1 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 2-10 shows the header format and sequence of the ancillary data inserted into the  
video stream. This format also stores any VBI data into the FIFO. The size of the FIFO is 512 bytes.  
Therefore, the FIFO can store up to 9 lines of teletext data according to the WSTB standard.
