Description, Features and
Benefits Thank you for purchasing the Vidikron VDP-80 Digital Video Processor. The Vidikron VDP-80
Digital Video Processor provides a cornerstone for the ultimate home theater experience. It
has been designed to offer superior video processing quality, while providing for multiple
component integration with your high definition Vidikron home theater display. We hope
you find that the VDP-80-720 exceeds your expectations.
Product Overview The primary functions of the VDP-80-720 are to act as a video switcher, process the selected
input, and output in the appropriate format and resolution. Standard definition (SD),
enhanced-definition (ED) and high-definition (HD) video inputs are all supported in addition
to a number of PC formats. Video inputs are converted to progressive video (as required) and
are scaled to the appropriate HD video output resolution.
Interlaced video has been in use for more than 50 years and is still the most common video
format. It displays half of the lines of picture information each sixtieth (or fiftieth) of a second.
Each half of the image is called a field and displays either all the even lines or all the odd lines.
So, an entire image, called a frame, takes a thirtieth (or twenty-fifth) of a second to display on
the screen. An “i” suffix on the resolution specification indicates an interlaced format.
In contrast, progressive video presents each frame as a whole. A “p” suffix on the resolution
specification indicates a progressive format. Converting interlaced video to progressive
video is referred to as “deinterlacing.”
The VDP-80-720 is comprised of four major functional sections:
• Input selection, conversion to digital (if needed), and video decoding
• Deinterlacing
• Filtering and scaling
• Conversion to analog video, or output as digital DVI-D video
These functional blocks are shown in Figure 1-1.
