On November 30th, the FCC is requiring that many television stations provide access to emergency information for people with visual disabilities. In order to comply with this requirement, we are now transmitting a second audio channel on WETM 18-1 that viewers can select instead of the main audio. This service is usually called "SAP" (Seconday Audio Program) or MTS (Multichannel Television Sound).  

Here is what you will typically hear on the SAP channel:
    • Emergency information from crawls, read by an electronic voice;
    • Video description audio, if the program has it available;
    • Normal program audio, if no video description track exists.

How do viewers get this service (or turn it off)?
Most TV remote controls have a button marked "SAP", "MTS", or "SAP/MTS". Usually, you press the button until you hear the sound you want; the screen will show something like "1 - ENGLISH" (for the main audio) or "2 - VI" or "2 - UNDEFINED" (for the SAP audio).

What is "video description"?
Just as closed captioning makes television accessible for people with hearing problems, video description improves accessibility for people with visual disabilities. Typically, this service is a copy of the main program audio with additional voice-overs that describe the action taking place.

What else might someone hear on the SAP channel?
Depending on the programming, it's possible that the SAP might contain Spanish content.
