HDBaseT Technology

Q: What is the HDBaseT technology?

A: HDBaseT technology is optimized for the delivery of uncompressed, ultra-high-definition digital media, and can connect all the entertainment devices in the home through its 5Play™ feature set, converging uncompressed ultra HD 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.

Q: What is the minimum requirement for HDBaseT?

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.

Q: What video and audio formats are supported by HDBaseT?

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.

Q: Does HDBaseT travel on an Ethernet network?

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

Q: Are there any special connector or cabling requirements that differ from existing Ethernet LAN products?

A: No, this is what makes HDBaseT so unique and easy to deploy. HDBaseT utilizes the existing Ethernet infrastructure meaning adopters can use existing Cat6 LAN cables, Ethernet in-wall passive connectors and RJ45 Ethernet jacks, while electronics manufacturers also utilize the existing RJ45 connector.

In addition, HDBaseT is fully backward compatible with Ethernet protocol, and connected devices can automatically switch to Ethernet communication mode only.

Q: what kind of control signals can HDBaseT drive? 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 propriety controls to be used when their equipment is on both ends. HDBaseT was designed to support different types of media and controls and it is built into the technology and the devices.

Q: What’s HDBaseT Class B? Does it support the same features?

A: Class B is a class defined and certified by HDBaseT Alliance.

This class provides a more cost-effective solution for industry applications seeking selected HDBaseT functionality at shorter distances.

It supports transmission distances of up to 70m/230ft.

It does not support Ethernet functionality.

Q: The technology is capable of delivering a charging power of up to 100 watts; is this power supplied through the data cable to the device?

A: Yes, it is.

Q: What is the maximum size of TV that HDBaseT can power?

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.

Q: Does HDBaseT Support 4K?

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

Q: How is HDBaseT technology different than others?

A: Unlike other HD distribution technologies currently available, HDBaseT is the only technology that enables long-reach wired connectivity up to 100 meters 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 also require a specific cable and/or a new proprietary connector while HDBaseT utilizes the existing Ethernet infrastructure.

HDBaseT Certification Program

Q: Is there a product certification program?

A: On June 15, 2011, the Alliance announced the 1.0 Certification Program. The Certification Program provides members with a set program for ensuring their products are compliant, interoperable 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.

Q: Are there certified devices available?

A: Yes. The first HDBaseT certified products were announced on June 15, 2011 in conjunction with the certification program launch. These products have gone through thorough testing based on HDBaseT CTS, ensuring they work in accordance to all functionality specified in the HDBaseT 1.0 specification and are interoperable with other HDBaseT products.

There are already dozens of HDBaseT certified products available , all of which can be found on the certified products list page.

Q: How can I tell if a product has been certified?

A: Look for the HDBaseT logo. Only certified products can carry the HDBaseT logo on them.

Q: What does the HDBaset logo indicate when placed on a product?

A: The HDBaseT logo indicates the product complies with the HDBaseT standard for, is interoperable with other HDBaseT products that are certified for the same features. It is the Alliance’s priority to encourage its members to submit their products to testing and certification, and to educate the professional installers’ community to look for the HDBaseT logo.

Q: Are all HDBaseT certified products compatible with any/other HDBT certified product?

A: No. HDBaseT products are certified for the features they support according to the HDBaseT standard, but not all HDBaseT products support all 5Play feature set. In addition, there may be interoperability issues not related to HDBaseT that may affect operation. 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.

For example, Vendor A can design certain RS232 commands that work only with its own products. Vendor B uses different RS232 commands and in fact might interpret a “Power-on” command as a “Power-off” command. If you connect the two devices using HDBaseT, they will probably not work properly, just as but we all understand that the same issue will occur when the devices are connected without HDBaseT.
