The TV set covers screens sizes 23 and 26 inch (both in 16:9
ratio) and has a styling, called Disc.
This chassis has the following features:
•

Audio

: The sound processor is part of the UOC processor

(called “Hercules”). The chassis has a FM Radio with 40
preset channels.

•

Video

: Enhanced video features, video drivers, Active

Control and multiple PIP.

The architecture consists of a TV and Scaler panel, I/O panel,
Side I/O and Local Keyboard panel and Power Supply panel.
The functions for video/audio processing, microprocessor (P),
and CC/Teletext (TXT) decoder are all combined in one IC
(TDA120xx, item 7011), the so-called third generation Ultimate
One Chip (UOC-III) or “Hercules”. This chip has the following
features:
•

Control, small signal, mono/stereo, and extensive Audio/
Video switching in one IC.

•

Upgrade with digital sound & video processing.

•

Alignment free IF, including SECAM-L/L1 and AM.

•

FM sound 4.5/5.5/6.0/6.5, no traps/bandpass filters.

•

Full multi-standard color decoder.

•

One Xtal reference for all functions (microprocessor, RCP,
TXT/CC, RDS, color decoder, and stereo sound
processor).
