Brief IC Descriptions
9.2.1
IC200
The UOCIII series combines the functions of a Video Signal
Processor (VSP) together with a FLASH embedded TEXT/
Control/Graphics microcontroller (TCG microcontroller) and
US Closed Caption decoder. In addition the following functions
are added:
•
Adaptive digital (4H/2H) PAL/NTSC comb filter.
•
Teletext decoder with 10 page text memory.
•
Multi-standard stereo decoder.
•
BTSC stereo decoder.
•
Digital sound processing circuit.
•
Digital video processing circuit.
The UOCIII series consists of the following 3 basic concepts:
•
Stereo. These versions contain the TV processor with a
stereo audio selector, the TCG microcontroller, the multi-
standard stereo or BTSC decoder, the digital sound
processing circuit and the digital video processing circuit.
Options are the adaptive digital PAL/NTSC comb filter and
a teletext decoder with 10 page text memory.
•
AV stereo. These versions contain the TV processor with
stereo audio selector and the TCG microcontroller. Options
are the digital sound processing circuit, the digital video
processing circuit, the adaptive digital PAL/NTSC comb
filter and a teletext decoder with a 10 page text memory.
•
Mono sound. These versions contain the TV processor
with a selector for mono audio signals and the TCG
microcontroller. Options are the adaptive digital PAL/NTSC
comb filter and a teletext decoder with 10 page text
memory.
