Typical Application
with the on-screen display unit,
providing a display bitmap for
super-imposing onto display video.
It supports two modes, base mode
(1 bit/pixel, 2 bits/pixel, 4 bits/pixel,
8 bits/pixel, support for transparencies,
and 256-level Alpha-blending) and true
color mode.
The video encoder supports NTSC, PAL,
and SECAM standards. It has been
designed to accept input video data that
is compliant with CCIR-601/656,
supporting both 8-bit 4:2:2 and 24-bit
4:4:4 formats for RGB and YCrCb.
The color matrix is designed to support
a wide variety of modes and provides
the highest quality composite output
signal. Two-times oversampling of the
output signals is accomplished by
filtering the input signal and recon-
structing extra samples in between the
existing ones. Three 9-bit resolution
output DACs have also been integrated.
