NTSC/PAL TV decoder, digital NTSC/PAL TV encoder, and video overlay controller. The VAC2000 accepts live NTSC or PAL analog video from a variety of sources including video cameras, digital video recorders or broadcast equipment. It can combine video with graphics or, video with video and provide output to drive a VGA monitor, TV monitor or TMDS flat panel display.
1: Introduction VAC2000 Hardware reference manual Features NTSC/PAL input Live video input from NTSC or PAL composite or S-Video. (TV-decoder): Input from camcorder, video camera, VCR and broadcast signals. Full NTSC and PAL resolution. Software-controlled 4-input (composite) or 2-input (s- video) video source selection.
1: Introduction VAC2000 Hardware reference manual Technical specification Video input: Composite or S-Video monochrome, NTSC or PAL. Four software selectable video input sources. Software selectable brightness, contrast and saturation control. 1V peak-to-peak (75Ω termination). VGA display output: 640 x 480, 800 x 600, 1024 x 768 resolution as well as 720 x 480 (NTSC) and 720 x 576 (PAL).
An input video multiplexer allows any one source to be selected under software control. Video inputs and outputs on the VAC2000 are provided on; low profile MMCX RF connectors for composite and S-Video, a 2 x 5 header for VGA output and a HIROSE 30 way flat-flex cable connector for flat panel TFT digital output (TMDS).

VAC2000 Hardware reference manual Video overlay on text/graphics The VAC2000 allows the live video stream from the decoder to be overlaid as a rectangular window on top of, or blended with, text and graphics on the display screen. Internal hardware video and graphics acceleration ensures that the live video window can be scaled, repositioned and blended with minimal host CPU intervention.
IDSEL on the PC/104- Plus Plus bus. PC/104- with +5V logic tolerance. Windows, Linux or QNX (depending on VAC2000 SDK). Display devices VGA monitors – for annotation output. NTSC/PAL video monitors – for annotation outputs Video input NTSC/PAL camera or device with composite NTSC/PAL output.
