I own and operate a local hospitality visitor channel in SW Florida that serves over 35 hotels in our area. Doing a local insertion into older analog Direct TV systems is not a problem for us using a modulator and playback unit to reside on a vacant channel in the hotel cable system. We are unable to do a local insertion into the newer SWM systems. Bulk TV, the local installer, has been unhelpful and unresponsive in assisting us. Can anyone out there explain how we can accomplish our local insertion into these systems?
