Teletext
The HMP8117 supports ITU-R BT.653 625-line and 525-line
teletext system B, C and D capture. NABTS (North American
Broadcast Teletext Specification) is the same as BT.653 525-
line system C, which is also used to transmit Intel Intercast
information. WST (World System Teletext) is the same as
BT.653 system B. Figure 16 shows the basic structure of a
video signal that contains teletext data.
The scan lines containing teletext information are monitored.
If teletext is enabled and teletext data is present, the teletext
data is output as BT.656 ancillary data.
