HDBaseT: Television Through Network Cable?

Post by **PressBot** » Sun Jul 04, 2010 9:23 am

Credit goes to our friends at 3dvision-blog for catching this. HDBaseT 1.0 is a new standard in development for the purpose of transmitting huge amounts of data, including high bandwidth HD video, through a traditional RJ-45 connector. In addition to limited bandwidth, one of the disadvantages of HDMI 1.4, DisplayPort 1.2, and DiiVA is the short length of their connection cables (relatively!).

Through network cable, key advantages include 100 meter length, 100W support for powering remote televisions through the connection, daisy chaining, and more.

Dimitry what do you think of this especially since you are a big proponent of Displayport

If you find UTP and the 100 m figure familiar, so do I.

en.wikipedia.org/wiki/10GBASE-T

It doesn' really look like a consumer standard that should replace HDMI for home use, despite their claiming otherwise, but rather an alternative to all those component analog video splitters/repeaters/concentrators which they use in the stores to showcase the TVs, and a cheaper alternative to similar optic fiber HD-SDI conversion solutions. Overall, it's more like installation-oriented professional standard which most likely uses much of 10GBase-T internally and will most certainly come with proprietary rack-mount concentrators/routers that will convert HDMI/USB/whatever signals at a crazy price, because 10G Ethernet is not exacly a low cost solution at US $500-1000 per cable right now. Of course they would like to sell it to home users, but what home user needs 100 m of cable length for $500 worth of equipment?

Note that the founders of the consortium include Sony Pictures Entertainment, not Sony Electronics, and LG Electronics and Samsung are also members in competing consortiums such as DiiVA, WirelessHD, WHDI, and probably others. From Wikipedia references, HDBaseT was first announced in December 2008 as a development by the Israeli firm named Valens Semiconductor, and it didn't catch much attention back then. AFAIK, analog component and HDMI/DVI extenders for both optical fiber and Category 5 twisted pair which use proprietary protocols are known for quite a long time.

I'm a proponent of everything that is better than HDMI in regard to stereo 3D gaming on the PC, so I'm as much a proponent of dual-link DVI.
