Using GPS to track cargo shipments is nothing new...Many trucking companies have been doing this for years!

Macs = Art? In our house, we use an aging 17 inch "Lampshade" iMac as a fancy (and quite stylish) digital photo frame. We had it on hand and weren't actively using it any more, so we put it to use showing a screen saver of our pictures!

They are already starting to add aux inputs...Chrysler and GM already have this in many of their cars. About 75% of the rental cars I have driven recently have had one.

Two options...Try VLC or Handbrake...

Sounds like some of the (free) services that have been available in the US for quite some time. TDD (Telecommunications Device for the Deaf) and Relay operators who converse between TDD users and standard voice phone users are very common. Some are run by state agencies, others are run by the federal government.

I work as a Broadcast Engineer with high powered FM broadcast transmitters...I have seen these transmitters installed in the back of shipping containers all the time! Not my first choice for an install, but it does make for quick deployment and emergency recovery!

I was going to say the same thing! That was one freaky episode...

I agree with the earlier poster...It is the multicasting that will make HD Radio fly. Originally, this capability was not there. Commercial broadcasters (the ones behind HD Radio) feared that additional channel capacity would give them additional competition, so they were against it. Public broadcasters, on the other hand, were all for it! They often have more content than they have airtime, and no commercials! Maybe if commercial broadcasters adopt multicasting, we will (at least initially) see some commercial free HD2 signals out there from commercial broadcasters.

Some people believe it is a scam because one of the chief stakeholders is Clear Channel (one of the largest advertising companies in the United States who also happens to own a large number of radio stations).

Others point at the fact that the technology is not an "open" standard (like DRM--NO not THAT DRM--Digital Radio Mondiale). Ironic that an open standard for something has the acronym DRM... (side note--this is probably why most of the HD Radios out there do not have optical or coaxial digital outputs)

People also complain that the US did not adopt the same digital broadcasting standard as much of the rest of the world, DAB. The main reason for this is because the frequencies used for DAB in the rest of the world were not available here in the US. The FCC had already allocated them for other purposes. Also, broadcasters were not anxious to give up the large investments in their existing frequency allocations. As the recent spectrum auction demonstrated, licensing of radio frequencies is big business and involves a lot of money.

HD Radio was developed, and is licensed by a company called iBiquity. iBiquity was born out of a merger between several companies who were originally developing competing digital radio technologies for use in the US.

It is a bit of a compromise, because it allows for broadcasting of both an analog and a digital signal on the same frequency. Existing radios will continue to work and newer HD radios will take advantage of the digital signal if it is present. If the digital signal is not present, the HD radios will just act like a normal radio.
