HD Radio receivers are complex and difficult to create. A basic HD Radio receiver should have two different parts to it. A digital receiver is the first part of the antenna. This is where the HD Radio signal's information is kept. The upper and lower sidebands contain the information transmitted from the broadcasting towers. For HD Radio, you can receive album covers, text for song titles and artists, and obviously the sound as well. If your receiver falls out of the area of HD Radio, then the second part of the receiver will kick in. A conventional radio receiver is implemented into the design so that when a lost HD Radio signal occurs, your typical FM signal will pick up and give you a conventional sound.
These receivers are also equipped with the capability to receive multiple channels for a single frequency carrier wave. This means that with every specific radio station, you can pick up an alternative station as well. These are commonly named HD2 and HD3 stations and the process is also known as multicasting or multiplexing. HD Radio is capable to send one extra music channel and three extra talk channels before there is a loss in sound quality.
