Mobile High-Definition Link, or MHL, wasn't announced at CES 2012, but it was during CES that we at PopSci
really started to get excited about it. It's a new kind of technology that can be applied to just about any connector, like HDMI, USB, or any kind of proprietary port (including Apple's iPod/iPhone/iPad port), and it essentially gives those dumb old connectors a whole bunch of new powers. Some of those, like HDMI, for example, can't deliver power. But an MHL-supporting HDMI port sure can. That's how we can get things like the Roku Streaming Stick
, which is an entire Roku the size of a USB thumb drive that plugs right into your TV's HDMI port. Other cool features include the ability to control anything plugged into an MHL-enabled HDMI port with your TV's remote--no need to have several remotes scattered around anymore.
