What is HDMI?

HDMI or High-Definition Multimedia Interface is used to transmit uncompressed digital data such as audio and video over single cable. This cable is an alternative to old analog video and audio standards such as composite cable, S-Video, VGA, component cables and many other analog caring wires and cables. Modern HDMI Supports up to 3D high definition video in resolutions that are better than any other cable can provide. It is also capable of carrying up to 8 channels or uncompressed or compressed audio. HDMI is also backwards compatible with computer interface such as DVI, many of which do support HD audio and video over single cable as well. Bottom line is that HDMI is the best and fastest cable for your home entertainment systems.

History and Development

The founders of the HDMI are Hitachi, Panasonic, National, Quasar, Philips, Silicon Image, Sony, Thomson, and Toshiba. The idea behind HDMI was to design a new interface capable of transmitting digital video and replace DVI, which was currently a video standard. They also wanted to add audio support and backwards compatibility to DVI as well. First development attempts began in April of 2002 on HDMI version 1.0. The production began in 2003 and sales increased from 5 million in 2004 to over 400 million in 2009 and increasing. Currently HDMI is available on all HDTV’s sold as well as any high definition multimedia player.

Future of HD data transmission

HDMI has integrated well into current market being the current HD standard for most HD multimedia devices, and is definitely here to stay, at lease for a while. Sony, Samsung, LG and Valens are currently working on a new generation of HD carrying devices. They call it HDBaseT and is based on really simple to use network cables. You probably have one running to your computer right now. Based on their proposal the technology will be able to carry same amount of data as HDMI and more will be able to theoretically carry more with further development. On top of that you will also get a networking and USB function capability, something that HDMI does not support. Wait we are not done yet; you will also be able to run up to 100feet of cable without any range extenders, and you will be able to get up to 100 watts of power as well. So on top of HD video and audio over HDMI you will get networking, USB and power for up to 100feet all on one simple, and cheap, Ethernet cable. I see trouble for HDMI in near future.

According to the article posted on various tech sites technology should be coming out in second half of 2010 with greater integration in 2011.

My nerdy vision

We have all hear of wireless internet and we have technology that can cover relatively big area with one router and maybe few extenders, that are more that capable of HD video and audio transmission. Some of you have also heard of wireless power distribution that is being developed. Developers pay attention now, all I want to do is to wake up in the morning, buy a TV online, go to my transport room (maybe I am too much ahead of myself) pick up my TV with one hand (because it is OLED and extremely thin and light) put it on my table and say “TV on”. Well by that time we will probably have our TV’s integrated into our walls, so we will not by buying TV’s as we know them now. I have some other great ideas call me... :)
