GENERAL DESCRIPTION
The SAA4993H is a completely digital monolithic integrated circuit which can be used for field and line rate conversion of all global TV standards.

FEATURES
• Upconversion of all 1fH film and video standards up to 292 active input lines per field
• 100/120 Hz 2 : 1, 50/60 Hz 1 : 1 and 100/120 Hz 1 : 1 output formats
• 4 : 1 : 1, 4 : 2 : 2 and 4 : 2 : 2 Differential Pulse Code Modulation (DPCM) input colour formats; 4 : 1 : 1 and 4 : 2 : 2 output colour formats
• Full 8-bit accuracy
• Scalable performance by applying 2 or 3 external field memories
• Improved recursive de-interlacing
• Film (25 and 30 Hz) upconversion to 100/120 movement phases per second
• Variable vertical sharpness enhancement
• Motion compensated 3D dynamic noise reduction
• High quality vertical zoom
• 2 Mbaud serial interface (SNERT)
• Demonstration mode for noise reduction, motion compensation and colour overlay.
