Essentially a QAM modulator - HD input is RGB from the VGA output of your computer.
Reading the install instructions, there is brief mention of installing a provided notch filter in series with your cable feed. This creates a notch where ZeeVee can create a new channel. Quite similar to the old analog NTSC modulators; instead, uses the better QAM that cable systems and most HD TVs can detect and decode.
Question: how does ZeeVee know what notch filter to provide? Different cable systems have different empty channels. The docs don;'t seem to provide much detail in this area.
Then again, if you are not using cable feed, then you have the entire cable bandwidth available.
Somehow, I would have expected that future set top cable or satellite decoder boxes would do something like this. Like the ch3/ch4 modulators of old.
“An engineer explained to us that hundreds of ear impressions were gathered in the name of research, and while each one obviously boasted its own unique shape and size, one single characteristic remained uniform across the board: the entrance into the ear canal is not a perfect circle, it's an oval.”

Pretty clever!
