 STV0118
STV0118
I - GENERAL DESCRIPTION
The STV0118 is a high performance PAL/NTSC
digital encoder in a low cost pakage. It converts a
4:2:2 digital video stream into a standard analog
baseband PAL/NTSC signal and into RGB analog
components. The STV0118 can handle interlaced
mode (with 525/625 line standards) and non-inter-
laced mode. It can perform Closed-Captions,
CGMS or Teletext encoding.
Four analog output pins are available, on which it
is possible to output either S-VHS(Y/C) + CVBS1
+ CVBS2 or RGB + CVBS. Moreover, it is possible
to use two STV0118 in parallel to interface with
SGS-THOMSON’s MPEG decoder ICs that are
able to deliver a 54Mbit/s “double” YCrCb stream
(e.g. the STi3520M). This allows for example to
encode OSD in one of the streams only.
