3.4.1

NTSC/PAL Composite Video Output (TV Out)

The HiQVideo

 controllers provide video encoder support and a composite sync signal which some encod-

ers require.  DK boards incorporate an NTSC/PAL encoder from Analog Device (AD722 or AD723) to con-
vert the VGA signals to the composite NTSC video and S-VHS video signals.  The board provides a 
composite NTSC video connector J3 and a S-VHS video connector J1.  Pin W6 switches between NTSC 
and PAL modes. Composite Video Output is also referred to as TV Out.  It can be either NTSC or PAL for-
mat.  

Refer to Table 7 for TV-Out jumper settings.
