1:35 PM -- In the story about NFC (linked previously), I mentioned Miracast. That's a technology that lets a TV or PC simulcast something that's playing on your phone -- videos and games, specifically.

Miracast is Wi-Fi based, and the key is that Broadcom has gotten the latency down to imperceptible levels, making it usable for gaming. But that latency trick gets washed out when Miracasting a video, because Broadcom can't predict what encoder/decoder will be used. The latency is only about half a second, but it's noticeable.

Location-based technology got discussed but not really demonstrated. Broadcom's point was that an indoor environment, such as a retail store, can be hyper-wired with Bluetooth and even NFC sensors to provide pinpoint location of a user. That way, things like targeted ads -- assuming you want such things -- can become specific to the particular aisle you're walking down.

In a less creepy vein, Broadcom talked about combining adding location awareness to your calendar. Your phone could tell you, "Better leave now to make that 30-minute drive to your next meeting." That could come in handy.
