Verizon Wireless to Stream Super Bowl 2014 Using Next Generation LTE Multicast
Verizon Wireless will be testing out a new wireless technology that will allow for fast, unbuffered delivery of live streaming video on Sunday -- Super Bowl Sunday. But unless you're one of the small number of lucky attendees at a Verizon event in New York, you won't be streaming Super Bowl XLVIII that way.
A few Verizon subscribers will have a chance to stream the big game and test out the new technology at a remote "skybox" in Bryant Park, in New York City. Ironically, while Verizon tests a next generation technology to broadcast the 2014 Super Bowl without delays or buffering in New York, Verizon customers at the game will be blocked from all live video streams of the game while in the arena; Perhaps they can find some other way to catch the action -- like with their eyes. (If you're not at the Super Bowl or Bryant Park, here's how to stream the game).
Verizon calls the new LTE broadcasting technology LTE Multicast. It delivers content to multiple subscribers at once instead of sending separate streams to each user's device, according to Computer World. It's literally more like a broadcast than a cellphone signal, and its advantages are in speed and efficiency: it uses the spectrum more efficiently, knocking out wireless signal congestion and preventing those annoying buffering pauses for viewers.
The problem with mobile streaming video is that it's what GigaOm described as "unicast." Each device is getting a separate stream of content on a separate channel, even if many devices are connected to the same stream and the same cell phone tower. It eats up a lot of bandwidth, and if you have many devices all streaming the same video, it can overload the system (that's partly why Verizon is blocking streams at the Super Bowl).
An LTE broadcast or LTE Multicast combines all of those streams into a single feed, the same way that an old-fashioned on-air broadcast TV tower would feed the same signal to millions of television sets in a city. Even though the test is being run in a small room in Bryant Park, in principle, a wireless company could LTE Broadcast the same streaming video to thousands of devices in the same area -- say, at the Super Bowl -- and still only use a small part of its overall capability.
Of course, LTE Broadcasting is not just for streaming video -- that's just the consumer-friendly way to show off the technology. The same technology could be used by carriers to cut back on congestion in any situation where many devices on the same local network are requesting the same content -- like when the new iOS 7 nearly broke the internet after its initial introduction. Software updates or emergency messages could in principle be LTE broadcast throughout an entire network much more efficiently.
In order to enable LTE Broadcasting though, wireless companies have to set aside a portion of their spectrum, as well as set up content partnerships, upgrade network capabilities and software, and upgrade customer devices. It may take a little while before this becomes commonplace, but it appears that AT&T and Verizon are both planning on making this happen, so expect it to happen -- at least in parts -- by the end of the year.
