Table 16: Picture Mode (cont.)
Characteristic Performance requirement Reference information
Pix Border On/Off
Allows user to mask or show the inactive
portions of the raster such as ANC area for
digital and sync for analog.
When the border is on, the image is scaled to
correct the aspect ratio. W hen the border is
off, the image is either mapped pixel to pixel
(full screen SD), or minimally decimated to
reduce the atrifacts
Synchronization
Picture mode always uses internal timing; it
is not affected by external sync
Aspect Ratio
Allows choice of 16:9 or 4:3 for SD, to
support widescreen
