Controller Board

The VAC2000 PC/104-Plus multichannel video annotation and overlay controller board from !%Advanced Micro Peripherals%! features two real-time analog NTSC/PAL input channels. The boards can mix with one another or with computer-generated graphics and text for TV and VGA output. The device’s hardware relieves host processor loading and enables video systems to be created with low-power fanless processor boards. The VAC2000 accepts either two S-video inputs or up to four composite video inputs from video cameras, DVRs, TV broadcasts or other NTSC/PAL sources. Each input can be alpha-blended with another video channel or with graphics by using one of 256 translucency levels from opaque to transparent.
