Putting the HD in HDBaseT


So what is HDBaseT? It is a new technology that has many installers and Home Theater/DIY techies excited. HDBaseT will facilitate connecting consumer electronics equipment in the home/office in the manner that high end multimedia systems are connected. Thus it is optimized for whole-home and commercial multimedia distribution. It will connect all the entertainment devices in a setting through its 5Play™ feature set, converging uncompressed full HD digital video, audio, 100BaseT Ethernet, power over cable and various control signals through a single CAT5e/6 cable with RJ45 connectors (Up to 100m/328ft). 5Play™ makes it possible to cut the assortment of cables going to the device to a single cable.

What is HDBaseT's 5Play™ Feature set and what does it include?

Why should I care about 5Play™ you say? 5Play™ is an unrivaled feature-set that merges full uncompressed HD video, audio, 100BaseT Ethernet, power and various control signals through a single inexpensive CAT5e/6 LAN cable. The fact that 5Play™ does all of this, creating a network of your displays and sources, is what makes it so amazing. Imagine replacing a huge bundle of cables from the front of your media room to the back with a single Cat5e or Cat6 cable. You could even use Flat CAT5e UTP cable to hide that single line under carpet.


1) Full, Uncompressed HD Video
HDBaseT supports TV and PC video formats including standard, enhanced, high-definition and 3D video. It delivers Full HD/3D and 2K/4K uncompressed 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.


2) Audio
Audio is a requirement for most consumer electronics devices and is passed through the same media as video. HDBaseT supports all standard formats including 7.1 channel Dolby TrueHD and DTS-HD Master Audio.


3) 100BaseT Ethernet
HDBaseT supports 100Mb Ethernet capabilities, enabling televisions, hi-fi equipment, computers and other devices to communicate with each other and access multimedia content, including video, pictures and music stored around the house or on the web.


4) Power Over HDBaseT (100W)
Sending power over the same CAT5e / CAT6 cable gives people the option to forego plugging devices into the wall outlet for power, allowing greater mobility. HDBaseT can power remote TVs and other devices up to 100 watts, even devices not anywhere near a power outlet.


5) Various Control Signals
HDBaseT delivers different types of control signals for different purposes, starting from CEC, to RS232/USB and IR that operate remote equipment even when located in a different room.

Who and what industries will benefit from HDBaseT?

Consumer Whole Home Networking
The HDBaseT-enabled home networking experience allows the consumer to easily push content as desired from a central HDBaseT hub and reap the benefits of fewer cables, enhanced features and freedom from the electrical outlet, all with an inexpensive, long-reach LAN cable. An HDBaseT media hub can manage numerous HDBaseT enabled devices and seamlessly push the 5Play™ feature set from a chosen device to an HDBaseT enabled display anywhere in the home.


Digital Sign Manufacturers
Imagine an airport installation with multiple displays spread throughout the building. Although HDBaseT was developed as a point-to-point technology, it allows cascading and single point to multipoint distribution supporting both daisy chain and star topologies. Distribution flexibility, coupled with the unmatched 5Play™ feature set, positions HDBaseT as an ideal commercial connectivity technology for applications such as digital signage.


The Hospitality Industry
Whether connecting devices within a suite or accommodating a large conference within the hotel, the existing Ethernet infrastructure allows an HDBaseT network to be easily implemented. Using HDBaseT, professional installers can now network displays and devices (i.e. projectors) throughout hotel suites, lobbies and conference rooms to create a unified viewing experience for guests.


Healthcare IT Industry
HDBaseT healthcare uses include display installations in patient rooms, lobbies, waiting areas and more. HDBaseT can also link medical imaging devices such as CT and X-ray scanners to remote monitors, reducing a technician's exposure to radiation.


The Surveillance & Security Industries
Installation of multiple surveillance cameras spread throughout a large outdoor area usually requires very large distances and resistance to extreme environmental conditions. All camera and video intelligence resides at the server side and therefore is less costly and simpler to maintain.

Another benefit of HDBaseT is the reduced cabling cost and smaller cable footprint.

Long HDMI cables can be very expensive because of the heavy gauge wire required. Long SVGA cables can be hard to find, are subject to ghosting and are also expensive. If your building code requires plenum, the cost of HDMI and SVGA can go through the roof. Cat5e is very inexpensive; even if you are required by code to use plenum-grade wire, it's far less expensive than plenum versions of power cables, HDMI cables or VGA cables at the same or longer lengths. Also, because you are replacing 5 different cables with one Cat5e cable you need far less space to hide the cables. And for even more space savings you can use flat CAT5e or CAT6. At 1.87mm thick, you can hide these cables just about anywhere.

So let's review... What makes HDBaseT better than what's currently on the market?
And how does it compare to existing HDMI, DiiVA and DisplayPort technologies?

HDBaseT represents a digital home networking alternative to standards such as HDMI, RF, Coax, Composite Video, S-Video, SCART, component video, D-Terminal, or VGA, presenting a feature set previously unavailable in the CE industry. 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. HDBaseT supports all TV and PC video formats, including standard, enhanced, high-definition, and 3D video. It allows you to create a multimedia network of all of your home entertainment and consumer electronic devices. The cabling is inexpensive and takes up very little space. HDBaseT could mark the end of other HD transmit and receive technologies, especially when most homes are coming prewired with multiple Ethernet cable runs.
