Silicon Image UltraGig 6400 WirelessHD, hands-on (video)
Silicon Image is hoping that you'll want to play HD from your handheld device on a big screen without taking the more convoluted WiFi route using DLNA, Airplay and the like. As such, the company took its WirelessHD 1080p60 tech currently seen in bulkier gadgets like laptops and shrunk it to mobile size as the UltraGig 6400 wireless transmitter. It's now created a reference design for the tech in the form of the tiny chip shown highlighted in the image above, which it would like manufacturers to integrate in their handsets or tablets. To show how it works, they jury-rigged the chip into a smartphone and set up a receiver on an HD panel, so naturally we wanted to take an Android game for a spin on the big screen. The signal stayed solid thanks to the chip's focused antenna array and 30-foot claimed range, while distracting latency seemed to be minimal -- in line with the company's 5ms assertion. Silicon Image is still talking to manufacturer's to see who might like to integrate the tech into their devices, but until then, you can experience it vicariously in the video after the break.
Silicon Image reveals UltraGig 6400 wireless HDMI output for next-gen phones and tablets
Up 'til now, the WirelessHD standard has been best suited to large, thirsty devices like laptops, AV adapters and projectors. If we wanted video output from a battery-powered weakling of a mobile device, then we'd either be looking at a WiFi-based option like AirPlay, DLNA or Miracast, which can sacrifice bandwidth and latency, or at a wired connection like MHL, which effectively means tethering ourselves to the TV. However, Silicon Image claims it's come up with a new WirelessHD transmitter, the UltraGig 6400, which allows for gaming and full 1080p60 video and yet is easily light-footed enough to fit into a smartphone or tablet. The company's optimistic photoshop above shows off the compactness of the module relative to the type of flagship phone it'd one day like to be part of: the silicon itself is 10mm x 7mm in area, or a fifth the size of the older WirelessHD Gen3. Just as importantly, the 60GHz transmitter consumes less power than a smartphone's own local display (around 500mW, with a 30-foot line-of-sight range), has a mere 5ms latency to allow for interactivity, and shouldn't add more than $10 to the cost of manufacture. Of course, we'd have to add a little more to that sum in order to purchase the mains-connected HDMI receiver box -- but in return we'd get to enjoy all our mobile vices at something much closer to life-size.
