I - GENERAL DESCRIPTION

The STV0119A is a high performance PAL/NTSC

digital encoder in a low cost package. It converts a

4:2:2 digital video stream into a standard analog

baseband PAL/NTSC signal and into RGB analog

components.

The STV0119A can handle interlaced mode (with

525/625 line standards) and non-interlaced mode.

It can perform Closed-Captions, CGMS or Teletext

encoding and allows Macrovision

™ 7.01/6.1 copy

protection.

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 STV0119A in parallel to interface with

ST’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.

REVISION HISTORY

October 1996

Advance Data

February 1997

Preliminary Data

Main Modifications :

- to get direct connection to SCART in Y/C mode, R and G signals have been

moved as G/Y on Pin 20 and R/C on Pin 19.

- RGB levels have been rescaled for compatibility between CVBS/Y-C and RGB

levels with only one value of IREF(RGB).

- revision ID is now 02 hexa (register 18 dec).

May 1997

- Update of characteristics (DC and AC electrical characteristics).

- Revision ID unchanged.

November 1997

- Improvement of luminance filtering in case of OSD input data.

- Revision ID is now 03 hexa (register 18 dec).

- New sale type : STV0119A.

June 1998

- Adjonctions of missing information on AC characteristics for Teletext signals.
