Proving my point from before that everything wants to be “HD” these days<\/a>, I read the Zune HD<\/a> specs<\/a> that come out recently and in that I found out that it claims to support HD radio<\/a>. Amusingly enough, it does not claim mp3hd support which probably would’ve made the buzzword bingo crowds go wild. We can always hope for the next model! \ud83d\ude42<\/p>\n

So what is HD radio? The site says:<\/p>\n

Instead of sending out one analog signal, stations send out a bundled signal \u00e2\u20ac\u201c both analog and digital. Because it is digital, textual data such as traffic, stock info and song titles can be sent out, as well.<\/em><\/p><\/blockquote>\n

From what I understand, pretty much the same way RDS<\/a> is already done.<\/p>\n

The technology is not even new. The site lists news items from 2006 and yet I’ve never heard of it before. They claim<\/a> FM stations get “CD-quality sound” and (as I find pretty funny) AM stations get “FM-quality sound”. What is “CD-quality” in this context I wonder? I find no mention or details on what exact codecs or bitrates etc they use. Wikipedia’s page to the rescue<\/a>: it says you get approximately 100-150 kbps of a lossy “proprietary iBiquity HDC codec” which claims to be able to provide “CD quality as low as 64 kbit\/s”. Somehow I think that sounds a little too good to be true. According to wikipedia HD radio beats DAB in audio quality.<\/p>\n

And to top it all of, the FAQ<\/a> describes what the HD means:<\/p>\n

It does not mean either hybrid digital or high definition, it is simply the branding language for this new technology.<\/em><\/p><\/blockquote>\n

Personally I’ll just rather go IP all the way and stream my music\/radio\/video over that. I think media or content-specific transfer mediums\/concepts of this kind are technologies of the past. For this reason, I don’t think DAB+<\/a> will have much of a future either.
