PAL/NTSC HIGH PERFORMANCE DIGITAL ENCODER

STMicroelectronics 

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.
