New standard offers both lower costs, the potential to deliver more information and convenience
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. While that name may sound confusing, before you slap your head, this will not likely introduce a new kind of cable to your house.
Past A/V standards from industry groups have introduced a plethora of connectors (S-Video, HDMI, DisplayPort for example), so that makes this release all the more unusual. Instead of a new connector, it is based on the Cat 5e/6 network cables, commonly referred to as "ethernet cables".
