The HDBaseT Alliance, a standards development and popularization promotion group for the interface standard "HDBaseT", demonstrated the automotive Ethernet application at the electronic component 2016 "electronica 2016". At the "2016 InternaTIonal CES" held in January, the alliance also did similar demonstrations. This demonstration uses a vehicle-mounted transceiver IC, which is quite different from the CES demonstration. The CES uses a transceiver IC for consumer products.
HDBaseT was originally developed as a cable interface for audio and video products. It can transmit a variety of signals such as uncompressed high-definition video and audio signals using a common Ethernet cable, and can also supply power. At present, it is more and more adopted in the field of commercial audio and video products.
HDBaseT (vehicle HDBaseT) for automotive use also has the same features, not only to transmit HDMI, USB and Ethernet signals, but also to supply power. Unlike HDBaseT, which is used in audio and video products, a pair of UTP cables can be used. A maximum of 6 Gbps of signal can be transmitted with a pair of UTP cables up to 15 m in length. The demonstration uses the VA600T, a transceiver IC supporting the HDBaseT from Valens Semiconductor of Israel, to implement data transmission at 1 Gbps. Also targeted for applications in infotainment systems.
Since HDBaseT used to be the standard for audio and video products, the "Board Member", which is the dominant player in the HDBaseT alliance, in addition to Valens, also includes LG Electronics, Samsung Electronics and Sony Pictures Entertainment. Now, General Motors Corporation of America. Also joined in. In addition, Samsung acquired Harman International Industries, which is engaged in the business of in-vehicle infotainment equipment. Therefore, two large companies in the automotive industry have become members of the chairman.
In addition, companies in the automotive industry have become “Contributor Membersâ€. For example, Daimler in automakers and Delphi in auto parts manufacturers.

According to the booth commentator, the problem with the popularization of the HDBaseT is that the companies engaged in the IC business are currently “only Valesâ€. For this "single resource", the expectations of automakers are not too high. Therefore, "the Alliance is considering implementing IP licensing to other semiconductor vendors." Among the members of the HDBaseT Alliance is NXP Semiconductors of the Netherlands, which is estimated to be able to manufacture transceiver ICs that support the HDBaseT.
In the field of automotive Ethernet, BMW has taken a fancy and adopted Broadcom's data transmission technology "BroadR-Reach". At that time, in terms of the physical layer IC supporting the technology, only the Broadcom family was involved. BMW hopes that there will be other companies that can be purchased in addition to Broadcom, so NXP, which has developed CAN and FlexRay physical layer ICs, is proposing to develop physical layer ICs that support BroadR-Reach. NXP then developed a physical layer LSI that supports BroadR-Reach. Because of this experience, NXP is likely to manufacture transceiver ICs that support the HDBaseT.
In addition, the HDBaseT Alliance targets targets in addition to audio and video products and automotive applications, as well as applications in industrial networks. At the seminar held in the electronica 2016 showroom, the alliance also promoted the characteristics of HDBaseT that can also be applied in the industrial field.
