HDBaseT Using a Single LAN Cable
One HDMI cable is needed for uncompressed video and audio. An additional LAN CAT5e/CAT6 cable is needed to supply Internet to your new, Internet-enabled TV and another cable is needed to carry signals and controls to the games console. What about power? That’s another cable.
So you now have four cables. If that seems like a lot, imagine what it takes to install each of these cables and connect them to a Blu-ray player and game console, whether they are located next to the display or hidden in the basement 100 meters away.
