Per the FCC, Descriptive Video Service isn't required for every show or every station. »
www.fcc.gov/guides/video ··· on#top25Some highlights: FCC rules require local TV station affiliates of ABC, CBS, Fox, and NBC located in the top 25 TV markets (see list below) to provide 50 hours per calendar quarter (about 4 hours per week) of video-described prime time and/or children's programming.
Local TV stations in markets smaller than the top 25 also may provide video description. Check with your local TV stations.
Many Public Broadcasting System (PBS) stations also provide video description on a number of programs. Check with your local PBS station.
The requirement to provide video description is extended to local TV station affiliates of ABC, CBS, Fox, and NBC located in the top 60 television markets beginning July 1, 2015.
The top 5 non-broadcast networks - Disney Channel, Nickelodeon, TBS, TNT, and USA - must provide 50 hours per calendar quarter (about 4 hours per week) of video-described prime time and/or children's programming.
Subscription TV systems (offered over cable, satellite or the telephone network) with 50,000 or more subscribers must carry video description.
Subscription TV systems with fewer than 50,000 subscribers also may provide video description. Check with your subscription TV provider.
And more. You could be asking for something that just isn't available, not the fault of a useless customer service representative.
