HDBaseT — Extending Digital Audio Video Beyond Its Original Limitations

HDBaseT — Extending Digital Audio Video Beyond Its Original Limitations

Learn How HDBaseT Puts A/V Control in the Hands of Its Users

This is the second post in a four-part series called "Emerging Technologies That Will Shape the Next 5 Years."

The HDBaseT Alliance was founded in 2010 by LG Electronics, Samsung Electronics, Sony Pictures Entertainment and Valens Semiconductor. HDBaseT technology was designed to offer an industry standard connectivity solution for extending HDMI digital video content beyond the 20 or so meters supported by native HDMI cabling solutions. While HDBaseT can also extend network connectivity, it is not an IP solution. Instead, it's a point-to-point A/V connectivity solution. HDBaseT technology uses a pulsed-amplitude modulation technique (PAM16) to send its trademarked 5Play™ content up to 100 meters over category cabling directly from the source to sink device. The 5Play™ feature set includes uncompressed digital video, digital audio, control signals, fast Ethernet up to 100Mb/s, and power.1

In August 2013, the HDBaseT Alliance released the HDBaseT 2.0 standard. This new standard expands the application of HDBaseT technology from the physical layer of the OSI model to all seven layers. Termed "HomePlay," the HDBaseT 2.0 specification adds networking, switching and control point capabilities, and defines point-to-multi point connectivity—thereby providing multi-stream support. This includes support for Ultra HD (D4K) video performance and for USB 2.0 control and data transfer.2

The HDBaseT Alliance more than doubled in size from 2012 to 2013. At the time of this writing there are more than 65 adopters, and HDBaseT technology is at the core of some of the most sophisticated and exciting A/V products in the industry.3

There are a number of factors that will drive HDBaseT adoption, making this one of the key growth technologies in the A/V industry. HDBaseT is positioned to support Ultra HD, a high performance system that delivers more than four times the resolution of current HD display technology. A recent report by Futuresource Consulting, a UK-based research firm, found several factors that will contribute to HDBaseT's impressive growth curve. Among these are HDBaseT's Ultra HD (D4K) compatibility, its reliable connectivity at distances well beyond the typical 20-meter limitation of HDMI's native connectivity, its use of a single category cable (Cat5e, Cat6 or Cat6a) and the accelerating industry-wide growth of high performance projectors and large screen displays. These market forces will drive a 50% combined annual growth rate in HDBaseT deployment through 2016.4
