DTV radio


Digital-television radio, DTV radio, or DTR describes the audio channels that are provided with a digital television service. These channels are delivered by cable television, direct-broadcast satellite or digital terrestrial television. In terms of variety, DTR falls somewhere between regular AM or FM radio, and satellite radio. However, because it is delivered through a digital signal, the actual sound quality can be equal to or greater than satellite radio.

DTR may be available for free, or as part of a subscription television service. DTR music and audio channels are often provided as part of the "basic" television subscription service or package.

In a 2014 study, 11% of Americans listened to DTV radio on an average day, with 5.2% of time spent listening to audio attributed to DTV Radio.

In the United States, DirecTV offers up to 70 channels of Sonic Tap, and Dish Network offers 95 channels of SiriusXM Satellite Radio and Muzak for residential subscribers, depending on type of subscription. Music Choice offers nearly 50 channels, which all fit on a single digital cable TV channel through multiplexing. This includes still video images which are sent at a low bit-rate to identify the station and song, and give more info about the artist.CRN Digital Talk Radio Networks offers seven channels, all broadcasting talk radio. Terrestrial broadcasters account for over 450 audio channels. Some AM and FM broadcasters co-brand their DTV simulcasts with their traditional frequency numbers, such as WDNJ via WMBC-TV, and WSIC via WHWD-LD.
