its called a HDTV or ATSC reciever Box.
Samsung makes one that sells for about 150-200 dollars.
The antenna input I use for my off-air hd signal no longer works on my big hdtv. I was wondering if there was any kind of converters that would convert the coax from my UHF antenna to any other hd input; dvi, hdmi, or hd component.
thanks
