Introducing HDBaseT™

HTBaseT Technology

5Play™ on a Single Cable

HDBaseT technology empowers plug-and-play digital connectivity between HD video sources and remote displays. The 5Play feature set, converged through a single 100m/328ft CAT6a cable enables the delivery of:

  • Audio & Video – Uncompressed ultra-high-definition/3D video in up to 4K resolution and any standard
  • Ethernet – 100BaseT Ethernet
  • Control – Various control signals including CEC, RS-232, USB and IR
  • USB – Support for USB 2.0 and other native interfaces
  • Power – Up to 100W using Power-over-Cable

HDBaseT delivers ultra-HD/3D and 2K/4K uncompressed video to a network of devices or to a single device (both point-to-point and multipoint-to-multipoint). Since the video is passed through the HDMI chipset, HDBaseT is compatible with all HDMI formats, and supports all key features, including EPG, CEC, EDID, and HDCP. The unique video-coding scheme ensures the highest video quality at zero latency.

In addition, HDBaseT audio is also passed through directly from the HDMI chipset. HDBaseT audio supports all standard formats, including Dolby Digital, DTS, Dolby TrueHD, and DTS HD-Master Audio.

HDBaseT supports 100Mb Ethernet, enabling communication between televisions, sound systems, computers, and other CE devices as well as access to any stored multimedia content (such as music or video streaming).

HDBaseT also supports Ethernet Fallback Mode, which enables seamless integration between an HDBaseT device and an Ethernet-only infrastructure. In such a case, only the Ethernet capabilities of the connection are enabled.

HDBaseT enables multiple control signals for multiple purposes: Consumer Electronic Controls (CEC), Recommended Standard (RS)-232, and infrared (IR). IP control is also enabled due to the support of an Ethernet channel. HDBaseT’s wide range of control options provides manufacturers with virtually endless opportunities.

HDBaseT supports native USB 2.0, and can be configurable either as USB Host or Device. USB expands the functionality supported by HDBaseT to include KVM switches (keyboard-video-mouse), touch-screen functionality, industrial PCs and USB extensions.

Up to 100W of DC power can also be delivered over the same CAT6a cable. This major aspect of 5Play provides the freedom to place equipment where you want it and not where an available power source happens to be installed.

HDBaseT™ In-Depth

The HDBaseT™ offering consists of two complementary chips. A transmitter chip is implemented in the HD source device (e.g. Blu-ray player, STB). A receiver chip is implemented in the HD sink device (e.g. HDTV, projectors).


HDBaseT relies on Pulse Amplitude Modulation (PAM). Basically, this is the same tehcnology that is used to code Ethernet signals into twisted pair cabling, where digital data is represented as a coding scheme using different levels of DC voltage at fairly high rates.

However, HDBaseT™ uses a patented proprietary version of the PAM modulation, enabling its vast feature-set to be converged into a up to 100m single CAT cable, without the electrical characteristics of the wire affecting performance. It is important to note that, while HDBaseT uses the same coding technology as Ethernet and have an Ethernet channel, it is neither Ethernet nor packet based. It just relies on the same cabling, thus providing the inherent benfits of the cost-effective CAT infrastrcture.
