HDBaseT Now Supports 4K 60Hz 4:4:4, UL Cable Certification Program

New reference design for HDBaseT transmission supports full 18 Gbps HDMI 2.0, including 4K 60 4:4:4. HDBaseT Alliance will also partner with UL for Power over HDBaseT (PoH) cable certification program.


Valens, the developer of HDBaseT and founder of the HDBaseT Alliance, has announced the availability of a reference design for HDBaseT transmission of full 18 Gbps HDMI 2.0, including 4K @ 60 4:4:4.

The reference design leverages Lattice Semiconductor’s video connectivity ASSPs (Application Specific Standard Product) to enable Ultra High-definition (UHD) video transmission using visually lossless compression, while maintaining overall latency to a few microseconds.

The company says with its latest design, vendors and manufacturers will be able to develop solutions that address the growing appetite for Ultra HD 4K and HDR support.

“With this new reference design, we are addressing the market need for long range transmission of full 4K 60Hz 4:4:4 and HDR-enabled content,” says Gabi Shriki, head of A/V business line, Valens. “This solution is also a precursor to the future HDMI 2.1 specification, which will use visually lossless compression to support the higher format resolutions. Valens has a long-standing policy of listening to our customers’ needs, and provide the most suitable solutions to address their requests.”

Several companies are already introducing such solutions, and will be showcasing them at ISE 2017 in Amsterdam. 

The solution pairs Valens Colligo chipset (VS2310) with Lattice’s chipsets (SiI9630, a low-power HDMI 2.0 transmitter and SiI9396, a low-power HDMI 2.0 receiver), to deliver a turnkey design for HDMI 2.0 4K60 4:4:4 video signal transmission.

HDBaseT, UL Alliance Validate Quality

The HDBaseT Alliance and alliance member UL, the global safety science company, have announced a certification program for Power over HDBaseT (PoH) cables.

HDBaseT Alliance says the program targets cable manufacturers and addresses the increased performance and safety requirements of A/V installations. 

The new certification program evaluates a cable’s ability to carry DC power of up to 100 watts over the four pairs of the cable, per the PoH standard, and to maintain HDBaseT data transmission performance. The PoH standard is based on the IEEE 802.3at standard (power over Ethernet – PoE), with the necessary modifications to enable safe delivery.

Under the new certification program, UL will evaluate the cables in accordance with the soon-to-be published UL 4299 — Outline of Investigation for Power over HDBaseT (POH) cables.

“Until now, the HDBaseT Alliance had a Cable Recommendation Program in which it tested cables for HDBaseT transmission,” says Ariel Sobelman, president, HDBaseT Alliance. “The new cable certification program goes one step further, providing increased transparency to vendors and end users and identifying the best cables for complex installations. By cooperating with the leading safety company in the world, the Alliance reiterates our commitment to the highest performance levels in the industry.”
