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 analog 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)

? I2C 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.
