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, 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 th! at sum i n 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.
