A: 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.
A: 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.
A: 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.
A: 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.
A: 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.
A: No, this is what makes HDBaseT so unique and easy to deploy. HDBaseT utilizes the existing Ethernet infrastructure, meaning existing Cat6 LAN cables, Ethernet in-wall passive connectors and RJ45 Ethernet jacks.
In addition, HDBaseT is fully backward-compatible with Ethernet protocol, and connected devices can automatically switch to Ethernet communication mode only.
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.
A: 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.
A: Power over HDBaseT (POH) enables the transmission of DC power in conjunction with data signals over a single Ethernet cable to a distance of up to 100 meters/328 feet. The POH standard is based on the IEEE 802.3at standard (Power of Ethernet – PoE), with the appropriate modifications to enable safe delivery of up to 100 watts (W) over the four-pairs of the Ethernet cable, as necessary.
In a typical POH implementation, the power source equipment (PSE) is installed and powered by a 50- to 57-volt DC power supply, and all powered devices (PDs) then receive power directly over the HDBaseT link across all four pairs of LAN cables. Four-pair powering is the key to delivering more power with greater efficiency. Defined in the latest high-power PoE standards, four-pair powering gives PDs two power interfaces so they can receive twice the power of earlier two-pair solutions by using all four pairs of Ethernet cable.
For more information, please refer to the Introduction to Power over HDBaseT white paper.
A: PoH safely delivers the necessary amount according to the product being powered, up to a maximum of 100 Watts.
A: 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.
A: 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.
A: Yes. HDBaseT is the only standard that delivers uncompressed Ultra-HD 4K video for up to 100m
A: 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.
A: The Certification Program provides members with a framework to ensure their products are compliant and part of an established product ecosystem. This is an important milestone for the Alliance in promoting industry-wide adoption of HDBaseT technology for whole-home and commercial multimedia content distribution. The certification Program also assists installers and integrators in determining interoperability of different HDBaseT products.
A: Yes. The first HDBaseT-certified products were announced in 2011, ans since then hundreds of products have been certified. Certified products undergo thorough testing based on the HDBaseT Certification Testing Specification (CTS), according to the HDBaseT generation the product supports (Spec 1.0 and 2.0).
A: Check the HDBaseT Alliance Certified Product List.
A: The HDBaseT logo indicates the product has been certified by the HDBaseT Alliance. It is the Alliance’s priority to encourage its members to submit their products for testing and certification, and to educate the professional installers’ community to look for the HDBaseT logo.
A: No. HDBaseT products are certified for the features they support according to the HDBaseT standard, but not all HDBaseT products support all 5Play features. In addition, there may be interoperability issues not related to HDBaseT that may affect operation. Manufacturers may implement proprietary features not related to HDBaseT that may interfere with interoperability in general. For more information, please see the Product Certified List. HDBaseT is an important part of the solution, but it is part of the larger whole. Installers and integrators should also check the products’ datasheets and technical materials for more information.
