DVD recorders have HDMI out, but not HDMI in. Why the disparity?
(Credit: Crutchfield)CNET reader "deesmac" asks:
Why doesn't a DVD recorder have an HDMI in, as well as an HDMI out?
It's a great question. High-Definition Multimedia Interface provides the advantage of passing a high-bandwidth all-digital high-definition video and audio signal on a single cable, as opposed to the tangle of component video plus audio cables that were required for HD. (If those terms are Greek to you, check out the connectivity section of the CNET TV Buying Guide.) HDMI is now the standard connector for HDTVs and all of the HD-capable components that connect to them--DVD players and recorders, DVRs, game consoles, Blu-ray and HD DVD players, and even camcorders and PCs. But all of those are video sources that only have HDMI outputs. You'll find HDMI inputs only on AV receivers, HDMI switchers, and--of course--TVs. So, why the disparity?
