Sony PS3, First with HDMI 1.3a
The least publicized feature of the PS3 has to be that it's the first product featuring an HDMI port that meets the 1.3a specification. The latest version of HDMI supports previously unseen color depth in video. And to be honest it supports so many colors you won't even see all of them using those human peepers.
They say the human eye is capable of perceiving up to 10 bit color depth that produces over a billion colors. The new Deep Color specification goes up to 48-bit RGB color depth, well beyond the capability of human vision.
I was reading a great article called Understanding HDMI Ver 1.3 over at Audioholics. As a detailed account of everybody's favorite High Def Multimedia Interface it's a great read. Even I learned a thing or two from it - and I know everything, except of course where I left my keys. And why I woke up this morning on a bus bound for Buffalo with shaving cream on my hands. But that's another story!
The differences between HDMI and DVI are covered as well as HDMI's evolution since its inception in 2002. It's fascinating to note that it has doubled in bandwidth since the start. I remember back then people were saying it was overkill.
I lifted a couple of choice quotes from Audioholics article:
"HDMI and DVI video signals are identical."
If this is not totally clear to you, I suggest you read here.
"DVI may be combined with High-bandwidth Digital Content Protection (HDCP) technology"
This is another all important fact considering how critical HDCP is these days. If you've recently purchased any high def video equipment it will pay to know more about this short list of acronyms HDMI, DVI and HDCP.
