Dlanor, Khz refers to the horizontal pixel rate.
Interlaced refers to the fact that on Standard Definition displays, due to bandwidth restrains video data is encoded on an ODD/EVEN lines scheme, making use of the persistence of vision effect.
Progressive means that no ODD/EVEN scheme is used and all and all the screen is drawn in a single step (hence the name progressive...) this is what HD (High Definition) Television sets and computer displays use.
Because the progressive mode sends twice the bandwidth per frame it uses an horizontal transfer rate of 31Khz. The vertical refresh may vary from 30hz to 200hz depending on the display application (I believe the most a high end CRT display can do is 150hz)
So, the guy wanted to mention the 15khz/31khz thing but he missed the Kilo.
Also it's interesting to see how the PS2 graphics chip was designed to operate on HDTV frequencies from the very beginning but the software was not. If SONY really wanted to it could push the PS2 a bit further than they did. They prefered to scrap it and mve on to the PS3 instead... lol
