High Definition Radio and New Content Alternatives 305

An anonymous reader writes "Many people are aware that satellite radio is a viable consumer option thanks to massive marketing campaigns. What many people do not know is that an alternative, High Definition Radio, exists in most major US markets. IBM DeveloperWorks explains how HD Radio works and why the masses may soon be scrambling to adopt this technology and expand it to alternative content as fast as possible."

        I'm quite interested in HD Radio's "bitstreams 4-6 times the size" of satellite. On XM, the average bitrate of a music channel is 40kbps. HD Radio (IBOC) offers a total bitrate of 96kbps per station. So right there, you're nowhere near 4-6 times the bitrate of satellite. Add to that the fact that the HD Radio signal will be split most of the time into two or even three chunks for the HD2 and HD3 streams, and that bandwidth is looking pretty small. Plus, XM isn't working on surround sound, they already have it. It's called XM HD Surround, and it's available on a few channels using receivers with the proper decoder.

        So, on an HD Radio station that is not serving up any subchannels, the sound quality can easily blow away satellite. But once you start adding the HD2 and HD3 subchannels to the mix, which most stations will do, the sound quality argument falls apart.

      • HD Radio delivers 96Kbps at it's best right now. The all digital mode promises more, but we've got to get folks to give up their analog radios first. That's gonna take a really long time. Long enough that the issue will remain relevant where the viability of both new technologies is concerned.

        Additionally, most stations are giving up the higher 96Kbps bitrates in trade for multiple streams that range from 32Kbps to 64Kbps. This is on par with Satellite and does not differentate the two in a significant way.

    I don't see the motivation for HD radio right now - the receivers are WAY to expensive for what you get.

    If you are in your car, you won't be able to tell the difference between HD Radio and plain-old FM Multiplex (unless your car is so well soundproofed that it poses a danger to everyone else on the road because you cannot hear horns/emergency vehicles/etc.)

    If you are at home, for the cost of an HD setup you can get a HELL of a lot of music, or listen to sat radio.

    Now, *IF* they were *replacing* radio stations with a pure digital block, then I could begin to see the advantage.

    Wikipedia has this to say which clears it up a bit

    In hybrid mode, the AM version can carry 36 kilobits per second of data for the main audio channel, while FM stations can carry information at 96 kbit/s. HD Radio can also be used to carry multiple distinct audio services, called multicasting but actually more like multiplexing. Secondary channels, such as for weather, traffic, or a radio reading service, can be added this way, though it may reduce the audio quality of all channels on a station. Datacasting is also possible, and RDS-like metadata about the program and station are included in the standard. Stations may eventually go all-digital, meaning they could no longer be heard on a regular radio.
    Interesting to preserve backwards compatibility, but not as technically innovative as DAB...

In fact in-band digital radio sounds much worse than analog FM radio. The CODEC sounds so bad that the FCC came close to not approving it. Only strong lobbying by iBiquity, the holders of the patents on the CODEC, convinced the FCC to approve.

    HD Radio has many many problems, notably that its sideband transmission scheme crowds out adjacent low-power FM stations. Basically, it's Clear Channel's master plan to finally kill off the local competition. Oh, and guess who is a major investor in iBiquity and its patent portfolio? Yeah, Clear Channel.

    Have some samples to add? Get hold of me and I'll get them up.

    I collected these samples and wrote the paper linked above out of personal interest. I'm not employed, nor have an interest in either Ibiquity or the radio industry in general. Just joe listener wondering how badly his radio will get hosed! (Short answer, FM mode is no biggie --either people will like it or not. AM mode sucks hard and will make a mess of the medium. Knife the baby quick!)

    Enjoy!
