HDBaseT supported by the HDBaseT Alliance, is a consumer electronic (CE) connectivity technology for transmission of uncompressed high-definition video (HD), audio, power, home networking, and some control signals, over a common cable with a standard connector.[2]


The HDBaseT Alliance, incorporated on June 14, 2010 by Samsung Electronics, Sony Pictures Entertainment, LG Electronics and Valens Semiconductor, was developed to promote the HDBaseT technology originally created by Valens.[3] The HDBaseT 1.0 specification was also finalized in June 2010.[4] External accessories, such as dongles, were on the market in 2010 for devices not yet embedded with HDBaseT technology.[5] Products were demonstrated at the 2013 Consumer Electronics Show.[6]

HDBaseT supports category 5e or category 6 cables up to 100 m long, with 8P8C modular connectors of the type commonly used for Ethernet local area network connections.[7][8]

HDBaseT represents an alternative to standards such as HDMI, radio frequency, coaxial cable, composite video, S-Video, SCART, component video, D-Terminal, or VGA. HDBaseT connects and networks CE devices such as set-top boxes, DVD players, Blu-ray Disc players, personal computers (PCs), video game consoles and AV receivers to compatible digital audio devices, computer monitors, and digital televisions.[9][10]


HDBaseT delivers uncompressed video HD video to a network of devices or as a point-to-point connection. Uncompressed content supports all video sources, including legacy products, accurately renders gaming graphics and features such as electronic program guides, and does not degrade video quality or add latency. It supports TV and PC video formats, including standard, enhanced, high-definition, and 3D video.[11]


Audio is a requirement for most consumer electronics devices. Audio is passed through the same media as video, so all standard formats are included.[11] HDBaseT does not support ARC, a feature found on HDMI 1.4.


HDBaseT supports the 100 Mbit/s version of Ethernet over twisted pair known as 100BASE-T. This can provide Internet access, or enable televisions, stereos, computers and other CE devices to communicate with each other and access multimedia content, including video, pictures and music stored on the local network.[11]

Power over cable[edit]

Sending power over the same cable gives the option to forgo plugging devices into the wall for power. HDBaseT uses existing Power over Ethernet (PoE) technology and PoE+ to source low consuming CE devices, such as low-power Blu-ray players, monitors and TVs, and eliminate the need for external power cables. HDBaseT can power remote TVs and other devices up to 100 watts. A 40” TV connected via an HDBaseT enabled Cat5e/6 cable requires no power source, as it can be powered with 70 watts.[11]

Control signals[edit]

HDBaseT delivers control signals starting from CEC that operates basic functionality such as power-on, power-off and play/stop, to RS232/USB and IR that operate remote equipment even when it is located in a different room.[11]
