Digital-television radio , DTV radio , or DTR describes the
audio channels that are provided with a
digital television service.
[1] These channels are delivered by cable television,
direct-broadcast satellite or
digital terrestrial television .
[2] In terms of variety, DTR falls somewhere between regular
AM and
FM radio, and
satellite radio .
[3]
[4]
[5] However, because it is delivered through a digital signal, the actual sound quality can exceed both.
[6]
DTR may be available for free,
[7]
[8] 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.
[9]
[10]
In a 2014 study, 11% of Americans listened to DTV radio on an average day,
[11] with 5.2% of
time spent listening to audio attributed to DTV Radio.
[12]

[16]

[17] all broadcasting

[18] Terrestrial broadcasters account for over 450 audio channels.
[19]
[20]

WDNJ via
WMBC-TV ,
[24] and
WSIC via
WHWD-LD .
[25]
In Canada, digital television providers typically carry the digital radio service provided by
Stingray Music , which provides up to 100 channels, and song information provided through either metadata rendered by the set-top box, or through an interactive menu interface which allows the viewer to navigate through channels and view playlists.
[26] While the
Canadian Radio-television and Telecommunications Commission (CRTC) only specifically requires digital television providers to carry local community, campus, and
CBC Radio stations, some offer feeds of most local AM and FM radio stations available in their service region.
[27] Some terrestrial broadcasters also carry audio channels, such as CH6498, CH5535-DT,
CH2517-DT and
CJON-DT .
[28]

digital terrestrial television service,
free of charge using the
