It allows people to use a normal TV with a computer
Today's HDTVs can usually connect to PCs just fine, but that's only because they have HDMI or other PC-compatible ports.Regular TVs, those that only have composite or S-Video inputs, or other common plug, can't do the same, even if they are otherwise suited for such a task.
Area decided to do something about this, leading to the making of the SD-DSCV.
Basically, this is a VGA down-scan converter device, in other words an adapter that turns VGA output into legacy/TV-compatible signals, with outputs to match.
Of course, sacrifices had to be made: the maximum resolution is of 1,024 x 768 pixels.
In addition to the video ports, the Area SD-DSCV has an USB cable, which draws power from that interface.
