HDBaseT FAQ

1.What is HDBaseT?

HDBaseT technology enables the optimized delivery of uncompressed, ultra-high-definition digital media, and allows you to connect all entertainment and content devices throughout the home and/or business. The cornerstone of HDBaseT 5Play™ feature set uncompressed ultra-high-definition digital video & audio, 100BaseT Ethernet, USB 2.0, up to 100W of Power (through Power over HDBaseT POH) and various control signals all through a single 100m/328ft Cat6 cable. In addition, the latest HDBaseT specification also allows for fiber as a transmission medium for UHD video & audio, controls, Ethernet and USB, for farther reach.


2.How many HDBaseT specifications are there?

The initial specification – HDBaseT Spec 1.0 – was introduced to the market in 2010 as a point-to-point connectivity standard, and defined the 5Play feature set (video, audio, control, Ethernet, and power). In 2013, the Alliance released Spec 2.0, which brought several new enhancements to the technology, including expanding it as a multipoint-to-multipoint technology, supporting multistream and daisy-chain. In addition, Spec 2.0 also supports USB for multi-touch and KVM applications, features improved performance in the distribution of 4K (UHD) video with an enhanced error correction mechanism, and defines optical fiber as a suitable means of transmitting HDBaseT in addition to the original LAN cable, for much longer distances.


3.What is the minimum cable requirement for HDBaseT?

The technology was developed to work with the most basic LAN infrastructure, namely Cat5e cables, and indeed there are many HDBaseT projects running on this cable. Having said that, feedback from installers and integrators determined that best practices is to use Cat6 cable in HDBaseT installations, for better performance and error-free transmission.


4.What video and audio formats are supported by HDBaseT?

HDBaseT enables full ultra-HD/3D and 2K/4K uncompressed video, and is compatible with all HDMI formats. It provides the highest video quality, with zero latency, and directly relays digital audio from the HDMI chipset. It supports all audio standard formats, including TrueHD,DTS HD-Master Audio, Dolby Pro Logic Iiz 7.1 & 9.1, and more.


5.Does HDBaseT travel on an Ethernet network?

No. Although it uses an Ethernet jack (RJ-45) HDBaseT is based on a different protocol that standard Ethernet equipment cannot work with. Future generations of HDBaseT will include HDBaseT switches that will allow HDBaseT networking.


6.What kind of control signals can HDBaseT transmit? How can you differentiate between internet signals and audio streaming signals, for example?

HDBaseT enables RS232, IR, Ethernet, and USB 2.0. HDBaseT also allows vendors to send proprietary controls to be used when their equipment is on both ends. HDBaseT was designed to support different types of media and controls.


7.What is the difference between HDBaseT Class A and Class B?

Class A is the original HDBaseT standard, supporting the 5Play feature set: ultra-high-definition audio & video, controls, Ethernet, USB and power, over a single 100m/328 ft LAN cable. Class B was created to provide a more cost-effective solution for industry applications, seeking selected HDBaseT functionality at shorter distances. Class B support transmission distances of up to 70m/230ft, and does not support Ethernet functionality.


8.How much power does Power-over-HDBaseT (PoH) feature deliver?

PoH safely delivers the necessary amount according to the product being powered, up to a maximum of 100 Watts.


9.Is PoH compatible with PoE?

Yes, the PoH standard is based on PoE, and as such is compatible. In that case, the maximum power transmitted will be according to PoE.


10.What is the maximum display size that HDBaseT can power?

HDBaseT can power any TV which consumes no more than 100W. Today’s Energy Star™ 6.1 specifications restrict all TVs up to and including 60 inches to less than 100W. In fact, a typical 42-inch TV cannot surpass 65.9W. These specifications are constantly evolving (for the latest specifications and revisions, see more at https://www.energystar.gov/certified-products/detail/486/partners?fuseaction=products_for_partners.showTVs.) At these levels, HDBaseT has ample power delivery capabilities, to support even very large displays.


11.Does HDBaseT Support 4K?

Yes. HDBaseT is the only standard that delivers uncompressed Ultra-HD 4K video for up to 100m


12.How is HDBaseT technology different than other multimedia content transmission technologies?

Unlike other HD distribution technologies currently available, HDBaseT is the only technology that enables long-reach wired connectivity for up to 100 meters (328 feet) for uncompressed ultra-HD multimedia content and up to 100 watts of charging power via a single cable. HDBaseT is optimized for video applications and can connect all HDBaseT-enabled home entertainment devices by providing the 5Play convergence. Other existing solutions may require a specific cable and/or new proprietary connectors while HDBaseT utilizes existing Ethernet infrastructure.
