I’ve seen the future, and it’s using 50% less bandwidth to produce a picture with increased quality of up to 300%.
I just completed a tour of KLCS, a public broadcaster in Los Angeles. As Chairman of the FCC, visiting a television station isn’t necessarily that noteworthy. But today’s visit was different, because KLCS is about to make history.
KLCS has entered into an agreement with KJLA, a Spanish-language station in L.A., to become the first broadcasters in America to pilot the concept of sharing channels of spectrum, which are the airwaves that transmit mobile images and information to TVs, radios and other wireless devices.
Seeing is believing! On my visit I saw KLCS putting out 1 HD stream and 7 standard-definition streams of programming on its current allotted channel of spectrum, what they call multi-casting. What’s really exciting is that as part of the pilot program with KJLA, KLCS will test broadcasting two full HD streams of programming over the same channel. If the pilot works as engineers expect it will, this could be a game changer for the concept of channel sharing.
So why does this matter?
If you live in the United States and you are reading this, you realize that America has gone mobile. Most Americans would have a hard time imagining life without their smartphones, and tens of millions are similarly in love with their tablets.
The problem is that spectrum, the lifeblood of all wireless technologies, is finite. That wasn’t a problem before the mobile web, when most consumers were mostly watching videos or surfing the web at home. If we don’t free up more airwaves for mobile broadband, demand for spectrum will eventually exceed the supply. If you’ve ever been frustrated by websites that loaded slowly or videos that wouldn’t download to your phone, you have a sense what that world could look like.
