VR giants unveil standardised VirtualLink to simplify VR rigs
18 July 2018 | 0
Virtual reality (VR) headsets will standardise on a new physical connector standard, known as VirtualLink, that will be designed around the existing USB-C interface.
A consortium of the VR industry bigwigs, including Nvidia, Oculus, Valve, AMD, and Microsoft, have backed the interface. Notable exceptions appear to be Sony, whose PlayStation VR was not listed among the promoter companies, and Intel, which has backed the Thunderbolt specification. Companies that wish to join the consortium can do so at VirtualLink.org, which for now resolves to a Google Sites address.
Details of the VirtualLink spec itself were not immediately available, though the member companies said that the spec will support four high-speed HBR3 DisplayPort lanes, which are scalable for future needs; a USB 3.1 data channel for supporting high-resolution cameras and sensors; and up to 27 watts of power. It is not immediately clear what bandwidth the cable will support, or how scalable it will allow VR headsets to be. Anandtech, however, did the maths and concluded that the spec allows for 4K @ 120Hz with 8 bits per colour.
What the member companies did say, however, was that the cable would provide a standardised solution for VR cabling, which has used traditional HDMI display and USB cables. It also provides another kick to USB-C, which is quickly replacing the traditional USB-A cabling.
“Simulating reality requires incredible visual fidelity and processing power,” said Jason Paul, Nvidia’s general manager of gaming and VR, in a statement. “With a single, high-bandwidth cable, VirtualLink unlocks the full potential of the PC to power amazing VR experiences.”
This could be interpreted as a VR call to arms. Supposedly, VirtualLink will debut in “next-generation” VR devices, but it is not clear exactly when that will be. But when it does, make sure to squint: We already have “standard” USB-C ports as well as ones that support the new Thunderbolt spec, each typically labelled with a small icon. Will VirtualLink add a third?
