“Polk Audio will announce the next generation of HD Radio tuners that will establish a direction connection between HD and iPods — and in the process bring e-commerce to HD. In an alliance with Apple, Polk’s new I-Sonic ES2 HD Radio will include an iPod docking station that features a “tagging button” which will allow listeners to buy songs they hear on HD Radio stations via iTunes. The advancement requires HD stations to encode their signals and insiders say eight radio groups have committed to encoding.” –
