Made possible by a chipset from Valens Semiconductor, the HDbaseT Alliance is inviting companies to join. There is a HDBaseT Comparison Table listing details of other current and future technologies alongside the HDBaseT 1.0 spec.
The HDMI cable was an incredible advance when it first arrived, but it isn’t easy to pull one through conduit and create an end in situ. The cost of using the technology was also the cost of the chipset, plus a payment based upon quantity with the HDMI alliance. The HDBaseT Press Release doesn’t mention any license fees.
It takes just a little thinking to realize how important a technology that can pass network data, USB, control data, daisy-chain (or star) devices, plus pass audio and video. The pr mentions a video recorder serving all devices in a multi-TV house, but it goes much farther. The digital signage field has handled some of these protocols, for example, but it has been through proprietary work.
