DIGITAL VIDEO ENCODER

The KS0123 multi-standard video encoder converts CCIR

656 8-bit multiplexed digital component video into analog

baseband signals. It outputs composite video (CVBS) and

S-Video simultaneously at three analog output pins.

44 PLCC

The encoder implements Macrovision revision 6.0 anti-

taping scheme. Additionally, it contains a color subcarrier

genlock to support analog/digital video splicing.

The video outputs conform to either SMPTE 170M (NTSC)

or CCIR 624 (PAL) standards.

FEATURES

• Macrovision revision 6.0 anti-taping support

• 8-bit parallel CCIR 656 CbYCr input format

• Synchronizes to CCIR 656 AVE time reference codes

for horizontal and vertical timing generation inslave

mode operation

• Generates HSYN and FIELD signals inmaster mode

operation

• Programmable subcarrier frequency, SCH phase,

and synchronous field display to support MPEG II

picture-coding-extension

• Optional subcarrier genlock to analog sfc_ref refer-

ence

• 650 kHz or 1.3 MHz chrominance bandwidth selec-

tion

• Support NTSC, PAL, PAL-M and PAL-N

• Switchable pedestal with gain compensation

• Selectable 37 nsec YC delay pre-compensation

• Video outputs meet SMPTE 170M or CCIR 624 spec
