Company News >> Introducing HDBaseT™

5Play™ on a Single Cable

Valens HDBaseT™ technology empowers plug-and-play digital connectivity between HD video sources and remote displays. 5Play feature set, converged through a single 100m/328ft CAT5e/6 cable enables the delivery of:

  • Video – Uncompressed high-definition /3D video in up to 4K resolution
  • Audio – Any standard digital audio format
  • Ethernet – 100BaseT Ethernet
  • Control – Various control signals including CEC, RS-232, USB and IR
  • Power – Up to 100W using Power-over-Cable

Video

HDBaseT™ delivers Full HD/3D and 2K/4K uncompressed video to a network of devices, or as a point-to-point connection. Video transmission is based on a pass-through from an HDMI chipset, thus supporting all key features of HDMI 1.4, including EPG, CEC, EDID, HDCP and more. Valens proprietary video coding scheme ensures the highest video quality with zero latency.

Audio

As in for video, HDBaseT™ Audio is passed-through directly from the HDMI chipset, thus supporting all standard formats, such as Dolby Digital, DTS, Dolby TrueHD, DTS HD-Master Audio and more.

Ethernet

HDBaseT™ supports 100Mb Ethernet capabilities, enabling televisions, hi‐fi equipment, computers, and other CE devices to communicate with each other and access stored multimedia content, including video streaming, pictures and music. Relying on the same physical infrastructure, HDBaseT™ also supports Ethernet Fallback Mode. This means you can plug an HDBaseT device into an Ethernet‐only infrastructure, and the device will seamlessly "realize" it, and will only enable the Ethernet capabilities of the connection.

Controls

HDBaseT™ delivers different types of control signals for different purposes, from Consumer Electronic Controls (CEC) to Recommended Standard (RS)-232, USB and infrared (IR). Since HDBaseT™ also caters for an Ethernet channel, IP control can also be used. This opens endless possiblities for equipment manufacturers, from remote control over distant devices to complete managed network capabilities.

Power

As part of its 5Play™ feature-set, HDBaseT™ supports transmission of up to 100W of DC power over the same CAT5e/6 cable. This significant feature provides the ultimate possiblity to forego plugging devices into the wall outlet for power, allowing greater mobility.

HDBaseT™ In-Depth

The Valens 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.
