The Qualcomm VP says Netflix-style streaming technology and over-the-top services will make mobile TV possible. For all that’s going on at NAB 2012, click here.
Widespread TV broadcasting through smartphones is coming, and Dynamic Active Streaming over HTTP (aka DASH), the same technology Netflix users access to watch movies on their smartphones, is the way it’s going to get there. That’s the belief of G. Kent Walker, VP of technology for Qualcomm Inc., speaking at the NAB Show Saturday.
“Walling up bandwidth, setting up a dedicated channel and letting it run is very expensive,” Walker said. “The first thing you’ve got to be is flexible. There isn’t that one user per cell per sector; don’t do it as broadcast. You’re wasting bandwidth and ultimately you’re wasting money.”
DASH, on the other hand, “works much better on a mobile device than RTP,” Walker said. (RTP is real-time transport protocol, a format used in TV services to deliver audio and video over IP networks.) “The principal reason is because it inverts the relationship between whose driving the pipe,” Walker said. “With RTP, the server is trying to figure out what does the handset the best.… DASH turns this around and is a much more effective way to do things.”
And having the content get to phones over the top will be the best way, Walker said. “Why? Because the receivers are already there,” he said. “Getting people to put their receiver on your phone is a really hard problem,” particularly since mobile handsets are cycled through every two years.
