DESCRIPTION
The STi5505 provides a very highly integrated back-
end solution for DVD and combo DVD-DVB (Set
Top Box) applications. The STi5505 incorporates a
host CPU which handles both general application
(DVD navigation, CD-DA, VCD, DVB) and drivers
of the different embedded periphals (audio/video,
subpicture decoders, OSD, PAL/NTSC encoder...).
The STi5505 offers one of the best cost-effective
(memory savings, internal peripherals availability) solu-
tion to DVD-DVB applications with rapid time to mar-
ket (Reference design, DVD-DVB Software Toolkit).
