Here comes wireless DisplayPort: VESA and WiGig team up


— 7:00 AM on November 3, 2010

The WiGig Alliance is certainly keeping busy. Just under six months after releasing their 7Gbps wireless spec and partnering up with the Wi-Fi Alliance, the WiGig folks now say they've teamed up with VESA to bring us wireless DisplayPort. WiGig and VESA are developing that technology with a certification program to match, and their goal is to deliver image quality on par with that of the wired DisplayPort interface.

As part of today's announcement, the WiGig Alliance says it's also completed "version 1.0 A/V and I/O protocol adaptation layer (PAL) specifications." The press release has more details about the two specs:

The WiGig A/V PAL (WiGig Display Extension) supports wireless transmission of audio/visual data. This implementation enables wireless DisplayPort and other display interfaces that include the High-bandwidth Digital Content Protection (HDCP) 2.0 feature. This PAL offers key A/V applications, such as the transmission of compressed or uncompressed video from a computer or digital camera to an HDTV, monitor or projector.

The WiGig I/O PALs (WiGig Bus Extension and WiGig Serial Extension) define high-performance wireless implementations of widely used computer interfaces over 60 GHz. These PALs enable multi-gigabit wireless connectivity between any two devices, such as connection to storage and other high-speed peripherals.

The complete specifications should be published early next year. We asked WiGig Marketing Group Chair Mark Grodzinsky when we can expect the first products based on those specs; he said he wouldn't be surprised to see samples next year, with the first products potentially arriving in late 2011 or early 2012.

Like what we're doing? Pay what you want to support TR and get nifty extra features.
