Graphics and display
Display
The STi5107 uses blitter based display architecture that allows the user to build a complex
user interface with background color, still picture, video plane and on-screen display (OSD)
as illustrated in
Figure 7.
OSD plane
The OSD plane is managed as a set of horizontal bands with a specification comprising
configuration, bitmap and, for CLUT formats, palette information for each region. The OSD
operates in one of two modes, palette mode or true color mode.
●
●
A vertical inter-field, anti flicker filter is provided to reduce flicker on interlace displays. It is
available for both palette and true color modes.
R e p la y
Palette mode: Each region can be independently specified with a resolution of 8 bpp.
Regions are frame based. Each region palette can support up to 256 colors with up to
24 bits resolution per color entry.
True color mode: Each region can be independently specified with a 16 bpp resolution
in one of the following direct color formats: RGB565, ARGB1555, or ARGB444.
