HDMI has certainly taken hold
in the consumer AV space and component video connection -- despite its merits
and supporters -- is in decline. Looking around at the back of a receiver, you might think that small, high density connectors used for digital signals are just better, right? Not necessarily -- consider the rearTwist BNC connectors Neutrik is bringing to the NAB (National Association of Broadcasters) show for 1080p HD/SDI (serial digital interface) use by pros. That's good-old coax design, specced out to 4.5GHz, with a kind of in-field reliability that our beloved HDMI connectors can only dream of. We're not bashing HDMI -- it's now mature
, has lots of nice features and puts great performance within the reach of lots of people. Also, discrete coax connections like these Neutrik connectors are too pricey for consumer gear; but don't be fooled into thinking that the move to HDMI was all about performance, either.
