HDBaseT 1.0 Spec Finalized

The HDBaseT Alliance recently announced the finalization of its first specification for distribution of HD video over standard LAN cabling.

The HDBaseT 1.0 base specification aims to distribute uncompressed HD video, audio, 100 Mbps Ethernet, power and control over standard CAT 5e/6 Ethernet cabling.

The Alliance claims that HDBaseT has the bandwidth to support full HD 1080p as well as 3D and 2Kx4K formats. A spec comparison chart listed a bandwidth of up to 10.2 Gbps, 100m maximum cable length and up to 100W of power available for devices. The chart also said bandwidth is scalable to 20 Gbps and up to 8 network hops can be supported. USB support is also mentioned.

Development and preparation of an HDBaseT Alliance Compliance Program is currently underway and first HDBaseT products are expected in the second half of this year, when spec licensing is also expected to be available.

The Alliance was founded by LG Electronics, Samsung Electronics, Sony Pictures Entertainment and Valens Semiconductor in December 2009.

I think this is a great idea because there should be some sort of a formal spec to streaming HD over the LAN. I am not sure about the claim of using CAT5e/6 to transmit 100W of power to the distant devices though. The claim is I can power a device that is up to 100meters away with a typical CAT5e/6 cable. I know that the existing technology of  Power over Ethernet can do this, but PoE can transfer low wattages to low-power devices like switches and routers which needs a typical 10W of power, but 100W is a lot more juice to push through.  The Ethernet cable is not built for carrying so much energy. The proof is by looking at a typical power cable which is thick with insulation. This is especially true when these cables are long.
