Watch the episode HERE!
It's only about 4 minutes long and is rather entertaining.

Now, someone has just explained to him what milk IS and where it comes FROM, and thus he's now having an existential crisis over the realisation of how incredibly decadent and wasteful his life of milk-baths has been.
The US already switched over to digital broadcasts, but remember that the digital signal still requires broadcasting over the airwaves, thus occupying some amount of bandwidth on the spectrum. Hell, even cable TV requires broadcasting, since individual networks beam their feeds to cable providers, who then send it via fiber-optic or whatevers.roid wrote:The Analogue TV signal is being phased out here already, i thought this was a global thing? When digital TV first came out here, it was introduced as a replacement for analogue with the understanding that it would be an eventual permanent switchover, the analogue signal would be switched off. There has thus been a rush to get digital set-top boxes to those who needed them, there was actually a government handout program for them iirc.

It seems to scan for unused frequencies and then transmit on the broadest bandwidth range it can get away with.--Cognitive radio will enable smarter use of wireless spectrum--

The device is the first that can operate from 100 megahertz to 7.5 gigahertz, meaning all the way from AM and FM bands though television and Wi-Fi and cellular frequencies. It can also sense available spectrum and switch between frequencies at around at 50 microseconds, and in some cases as little as one microsecond. This is a record speed, according to Peter Woliansky, a Bell Labs alumnus who made the gadget and founded the startup behind it.

Cognitive radio technology could enable a range of new services. For example, it could route cellular calls to Wi-Fi signals—something that is done today in small wireless base stations called small cells—but also avoid having to use fiber to send the signal out over the Internet, and instead use available television spectrum in the 400 megahertz range.

"You want to jump around in radio spectrum as fast as possible and as far as possible, and when you land somewhere, you want to grab as much spectrum as you can, and pump it in and out of the radio, and these are actually very challenging to do," says Chip Elliot, project director for the NSF's cognitive radio project at BBN in Cambridge, Massachusetts. "This radio is perfect for things like that."
