Standard changed:

0 = Video standard unchanged
1 = Video standard changed
FIFO full:
0 = FIFO not full
1 = FIFO was full during write to FIFO
The FIFO full error flag is set when the current line of VBI data cannot enter the FIFO. For example, if the FIFO has only 10 bytes left
and teletext is the current VBI line, then the FIFO full error flag is set, but no data is written because the entire teletext line does not fit.
However, if the next VBI line is closed caption requiring only 2 bytes of data plus the header, then this goes into the FIFO even if the
full error flag is set.
