It allows terrestrial radio stations to broadcast with a full digital signal, better than CD sound quality. You'll be able to get all parts of the music track sounding as they were intended to sound by the producer and engineer through your speakers. Makes AM sound like FM, and also allows up to 8 sub-channels per frequency, eg: a station can have 104.10, 104.11, 104.12, etc. Those sub-channels could carry alternate programming too. You could have syndicated programming which originates in NYC on a sub-channel of your LA FM HD station without the need to tape-delay the broadcast, and have your usual programming on the regular non-HD frequency. We are planning a sub-channel of all acoustic and live music by the artists we frequently play at our station. I get to program one of the sub-channels, but I doubt I'll get to put on it what I would truly like to.
