iBiquity Digital is demonstrating the first batch of receivers to make use of HD Radio and iTunes tagging. The technology enables users to "tag" songs they hear on FM radio that they like, marking them for later purchase and download.
HD Radio works both on FM radio and HD2 multicast radio channels. iBiquity says the technology provides CD-like quality audio over FM frequencies, with AM broadcasts able to sound more like FM quality, both absent of static, hiss, pops and fades. With iTunes tagging, users hear a song they want and "tag" it; that tag is then loaded onto the iPod. The next time the iPod is synced on iTunes, the selected songs are displayed on a list which you can then purchase through Apple's iTunes store.
iBiquity now counts more than 1,500 AM and FM stations broadcasting in HD and more than 700 in HD2 multicast. Companies including CBS Radio and Clear Channel are now implementing iTunes tagging in their broadcasts.
The first batch of HD Radio-equipped receivers hitting the market include devices from Alpine Electronics, JBL, JVC, Polk Audio and Sony.
