PICTURE-IN-PICTURE SIGNAL PROCESSING
1
DESCRIPTION
This system is an NTSC system PinP system that accommodates
subscreen composite input and main screen Y/C input. It is a
semiconductor IC circuit having a built-in 96K bit field memory and
an analog circuit, which permits a low-cost and compact system
configuration.
FEATURES
Built-in field memory 96K bit for PIP
Built-in luminance signal vertical filter
No. of subscreen displays: 1 (two sizes, 1/9 and 1/16, can be
selected from.)
No. of subscreen samples (1/9 - 1/16 sizes)
No. of quantization bits: 6 for all Y, B-Y and R-Y
No. of horizontal picture elements: 171(Y), 28.5 (B-Y, R-Y)
No. of vertical lines: 69/52
Subscreen frame display ON/OFF
Built-in analog circuits such as sync chip clamp, VCXO, and ana-
log switch
Built-in 2 channels of 8 bit A/D converter
(for main signal burst lock and PIP sub signal)
Built-in two channels of 8 bit D/A converter (luminance and
chroma signals)
I
C bus control
Controls: display ON/OFF, display size selection, setting of
display position, frame ON/OFF, setting of frame level, selection
of frame animation/field still image, setting of Y delay amount,
color level, tint, black level, etc.
