HDBaseT – Specification & Usability
HDBaseT is a consumer electronic and commercial connectivity standard for uncompressed high-definition video, audio, and power. HDBaseT is transmitted over a CAT6 cable, or above up to 328 ft long. It transmits uncompressed ultra-high-definition video, audio and power over HDBaseT. It’s complementary to standards like HDMI, and is an alternative for radio frequency, coaxial cable, and composite video etc. Uncompressed content supports all video sources. It also supports TV and PC video formats (up to 4K and 3D). HDBaseT can only support 4K at 30Hz and not the full 60Hz however.
Audio, is almost required for most consumer electronic devices. It’s passed through the same media as video, so that being the case, all standard formats are included. However, it does not support ARC (found on HDMI 1.4).
HDBaseT supports the 100Mbit/s version of Ethernet over twisted pair. This can provide internet access, or enable televisions, stereos, computers and other CE devices to communicate with each other. Sending power over the LAN cable also gives the option to delete power cables out of the picture. HDBaseT uses a variation of PoE (power over Ethernet) and can provide up to 100W of power to devices.
