Continued from Is China's DiiVA a Threat to HDMI?
DiiVA is not the
only newly emerging interface for AV equipment: another is HDBaseT,
developed by Valens Semiconductor of Israel, a fabless manufacturer
(Fig A1). A single Ethernet cable is used to pump uncompressed HD video
and audio simultaneously.
The intriguing features of the new technology are a long range (up to 100m) and the ability to carry power. These features were built in specifically targeting home networks interconnecting equipment in different rooms.
The cabling can be the same Category 5 or 6 cabling used for Ethernet, and it can use standard RJ-45 connectors, with no need for the special connectors that DiiVA needs. In other words, off-the-shelf cabling - which means minimal cost for introduction of cables, connectors, etc. For example, says a source at Valens Semiconductor, "For a length of four meters or more, the cabling cost is less than HDMI." It supports up to 50W of power over Ethernet (PoE), supporting standards like PoE (IEEE802.3af) and PoE Plus (IEEE802.3at).
Valens Semiconductor plans to sample-ship HDBaseT transmitter ICs in the third quarter of 2009, and is already marketing the technology to equipment manufacturers. In the future it plans to launch a promotion organization with participation by major equipment manufacturers.
