Transformative Engineering’s HD-4K Earns DPL Seal of Approval Designation is DPL Labs’ First Full 4K, 18Gbps Certification of an HDBaseT Category Cable ExtenderRS Staff ⋅ Apr 9, 2018 DPL Laboratories Inc., the digital testing laboratory specializing in the performance assessment of digital signaling solutions such as HDMI 4K Extenders, has issued the first Full 4K HDR 18Gbps HDBaseT Category Cable Seal of Approval to Transformative Engineering for the HD-4K. “Running HDBaseT extenders through our testing process just about always yields some disappointing anomaly. The Transformative Engineering HD-4K was no different except the anomaly turned out to be a superb performance level when pushed to its max distances with CED (Character Error Detection),” said Jeff Boccaccio, president of DPL Laboratories. “After 36 hours of run time, the system registered zero errors for all three TMDS channels. We have experienced short Fiber Cables that have generated as many as 200 errors over 10 minutes. This just means the HD-4K is doing a great job in the conversion process and output control. CED is one of the new features with HDMI Rev 2.0 where some active components have not fared very well. Copper is far from being extinct.” Jay Trieber, president of Transformative Engineering and president of Home Theater Concepts in Norwood, MA, remarked, “We are exceedingly proud to merit the first DPL Seal of Approval for our 4K HDR 18 Gbps HDBaseT over Category Cable HMDI extender. It is very exciting to gain the recognition of Jeff’s prestigious DPL laboratory. We all know DPL’s Approval is only awarded to HDMI equipment that tests to extremely high and rigorous standards. All of our products are designed here in Norwood, for custom installers, by custom installers. “Although the HD-4K was first released last April, 2017, the DPL Seal of Approval is just now announced due to the fact that DPL Labs had to design and build customized test fixtures allowing a portion of their Tektronix test equipment to run DPL’s “Augmentative Matrix Analysis”, the nucleus to DPL’s rigid testing process,” Trieber added.
