HDMI is now the most common format for AV signals in nearly all consumer, and even many professional, products. However, HDMI was only designed for home use and was never intended to run over distances of say 10m+. Individual manufacturers got around this by creating their own methods of sending HDMI over longer distances using CAT5/6 cable, but these were not compatible between different manufacturers.
HDBaseT is a common standard now used by many manufacturers for sending HDMI over long distances (i.e. 10m-100m) that should allow for compatibility between different manufacturers’ hardware and give buyers more certainty and future-proofing. It can carry HD video, stereo audio, control signals, LAN and power (PoH).
HDBaseT-Lite is a reduced version of HDBaseT that runs up to 60m and normally carries HD video and stereo audio.
