HDBaseT – new standard to replace ‘ageing’ HDMI home A/V interface


So the people in the home audio visual industries have just come together again to agree a new cable and interface standard called HDBaseT to replace HDMI. Aw c’mon people, you’re having us on right? You expect everyone to throw away their new flat screen television, set top boxes and other living room A/V peripherals next year just to ‘upgrade’ to the new standard? Dream on.

This kind of what I call wanton stupidity, where an industry delivers a sub-standard tech and then quickly upgrades it to encourage additional sales volumes sucks. Why can’t they get it right first time? So this HDBaseT combines HD video, audio, Ethernet and even power over a single super length Cat5 type cable, which is great. But all this should have been implemented at the start of the digital switchover instead of HDMI, all the technologies were around a few years ago. No excuses. Pfaff. More here.

 The cornerstone of HDBaseT technology is 5Play, an unrivaled feature-set that converges full uncompressed HD video, audio, 100BaseT Ethernet, high power over cable and various control signals through a single 100m/328ft CAT5e/6 LAN cable. HDBaseT has the bandwidth to support the highest video resolutions such as full HD 1080p as well as 3D and 2Kx4K formats. HDBaseT is the first to provide all-in-one connectivity, making it possible for a single-connector TV to receive power, video/audio, Internet and control signals from the same cable.


  • Yeah I know, another year another format, however I think HDMI will still be very useful. Can you imagine smart phones or digital cameras burdened with an Ethernet port? The long range HDBaseT should come in very handy.

    • i suspect we will see a number of hdmi to ethernet converters if this takes off (and honestly, i want to see it take off, as i am getting tired of all the cables and ports).

  • Hmmm… it wasn't that long ago when HDTV's only had component inputs. HDMI was "forced" down our throats. Add in HDCP with the anticipated analog sunset in Blu-ray players, and the anticipated implementation of the image constraint token, people with older HDTV's and projectors without HDMI will not be able to watch new movie releases in HD.

    I have not yet seen the HDBaseT spec, but the patent applications and the current implementation of chip sets available from Valens Semiconductor has HDBaseT defined as an add-on to HDMI rather than a replacement. Both an HDMI chipset and a HDBaseT chipset are required.
