HDBaseT,=20 developed by Valens Semiconductor of Israel, a fabless manufacturer (Fig A1) is a new emerging interface for = AV=20 equipment. A single Ethernet cable is used to pump uncompressed HD video = and=20 audio simultaneously.

The=20 intriguing features of the new technology are a long range (up to 100m) = and the=20 ability to carry power. These features were built in specifically = targeting home=20 networks interconnecting equipment in different = rooms.

The=20 cabling can be the same Category 5 or 6 cabling used for Ethernet, and = it can=20 use standard RJ-45 connectors, with no need for the special connectors = that=20 DiiVA needs. In other words, off-the-shelf cabling - which means minimal = cost=20 for introduction of cables, connectors, etc. For example, says a source = at=20 Valens Semiconductor, "For a length of four meters or more, the cabling cost is less than HDMI." It supports up to = 50W of=20 power over Ethernet (PoE), supporting standards like PoE (IEEE802.3af) = and PoE=20 Plus (IEEE802.3at).

Valens=20 Semiconductor plans to sample-ship HDBaseT transmitter ICs in the third = quarter=20 of 2009, and is already marketing the technology to equipment = manufacturers. In=20 the future it plans to launch a promotion organization with = participation by=20 major equipment manufacturers. =
