Typical Value

Overlay Support

Utilizes SPI interface to load overlay data from external flash/EEPROM memory with the

following features:

•Available in Analog output and BT656 Digital output

•Overlay Size 360 x 480 pixel rendered into 720 x 480 (NTSC) or 720 x 576 (PAL)

•Up to four (4) overlays may be blended simultaneously

•Selectable readout: Rotating order user selected

•Dynamic scenes by loading pre-rendered frames from external memory

•Palette of 32 colors out of 64,000

•8 colors per bitmap

•Blend factor dynamically programmable for smooth transitions

•Fast Update rate of up to 30 fps

•Every bitmap object has independent x/y position

•Statistic Engine to calibrate optical alignment

•Number Generator
