There seems to be a buzz starting up about this, but it seems unlikely that a group of just four players is going to unseat HDMI...or does it?LG Electronics, Samsung Electronics, Sony Pictures Entertainment and Valens Semiconductor have been secretly conspiring to kill HDMI. And today they set their plans into motion, introducing a brand new audiovisual standard, HDBaseT.
It supports cable lengths up to 328 feet. The cable can pass HD and 3-D video signals, as well as data through an integrated 100MBit Ethernet connection. That data feed should allow for new internet-connected TV services, such as Google TV which delivers advertising-funded services to TV sets.
The standard will begin its rollout later this year. The majority of its volume will hit in 2011.
