The data listings for TV stations will now include a new feature under "other information": mDTV. This is Mobile Digital Television, a separate broadcast that stations can use to target mobile video devices. Instead of the unreliable (for moving targets) 8-VSB used for our current digital multicasting, the signal for mobile viewers is encoded in a standard called ATSC-M/H.
The stations currently broadcasting the mDTV signal are WSFA and WAIQ in Montgomery and WBIQ in Birmingham. Other stations with a target 2011 launch date include WBRC, WBXA-LD, WVTM, WIAT in Birmingham, and WEAR, WFGX & WFNA in Mobile-Pensacola. There is no information on whether any TV stations in Huntsville, Columbus, Dothan or Biloxi are planning any roll outs.
